How to connect the pressure switch to the pump "Kid"

The process of connecting the accumulator

If the accumulator is connected correctly, then all further maintenance can be done independently. Therefore, connect this device correctly so that you do not suffer later during its operation.

A check valve must be used to connect the accumulator. The battery tank is connected to a submersible pump, so the valve will not allow water to flow. You can also choose a deep-well pump of the Gileks brand, which can be lowered to the bottom of a well or well. Of course, there are other types of pumps. After all, the pumping apparatus is also capable of pumping air for the pumping station. Let's analyze the usual case of mounting a hydraulic accumulator.

Hydraulic accumulator connection mechanism:

1. We measure the dimensions of the accumulator;
2. We get the scheme of pipes for water supply and heating;
3. We are looking for a free place for installation according to the dimensions;
4. Of the options found for installation, leave the place that is closest to the pump;
5. We connect the submersible pump to the accumulator.

Thus, you will calculate the place for installing the accumulator.

The device must be located as close as possible to the water pump. As a rule, batteries in this case are located at the entrance to the country house. In order to subsequently service the accumulator, it is necessary to calculate its integration into the cold and hot water system. This need is associated with the discharge of water from the tank. Therefore, be careful about the installation site.

Pump device "Kid"

It is based on the vibrational principle of translational motion. The electromagnet, by switching on / off, attracts and releases the armature with a rod and a return spring. A membrane is fixed on the stem, forcing fluid to enter the valve. The armature oscillation frequency is about 50 times per second. Simple, like all ingenious scheme, and very effective design. Some models of the pump have overheating sensors that allow you to avoid temperature overloads that turn off the equipment in a timely manner.

Main characteristics and important features of technical solutions implemented in various models of the Malysh pump

The technical characteristics common to all models of the "Kid" pump are:

• Supply voltage 220 volts.
• Throughput 432 ml/sec.
• Lower or upper intake.
• Power 250 watts.

There are also options that are reflected in the price. By the way, it is small from 1 thousand to 2500 rubles.At a low price for pumping equipment, the unit copes well with its tasks, is unpretentious in operation, convenient and productive, but due to its low power it cannot create high pressure. It enjoys excellent reviews among the owners of country houses, summer cottages and household plots.

Depending on the pump model, there are some design additions and changes. Let's consider them in more detail.

Kid Classic

The basic model without additional devices (thermal sensor idling relay filter), has a lower water intake, is distinguished by the possibility of pumping over long distances (up to 150 meters). The diameter of the connected hose is 18−22 mm. It is not designed to work in dirty water without an additional filter, which is not included in the package. Water with a temperature above +35 quickly leads to overheating and requires the unit to be stopped manually until it is completely cooled down. The limit of possible immersion to a depth of 5 meters. The model is very simple, which is reflected in the lowest price among all modifications of the product.

Baby - M

The product is similar to the base model. The only difference is that the water intake occurs from above and allows the unit to work in contaminated wells, wells and other sources. The remaining parameters correspond to the basic characteristics.

Kid - K

The main characteristics are also the same as those of the classic model, the difference lies in the built-in overheating protection device. The product can be used for long, continuous work without fear of breakage.

Baby - 3

The submersible pump "Kid-3" is the flagship of the model line. It costs a little more, but has very useful additions.

• The pump body, especially the electrical part, is placed in a hermetic case.
• The power of the electromagnet has been reduced to 165 watts, and, accordingly, energy consumption has been reduced, without sacrificing performance.
• The product is capable of pumping 0.432 m³/h at a head of 20 meters.
• Weight only 3 kg.

You can buy separately for any model, and install additional equipment and devices: filters, dry-running sensors that work on the principle of a float, irrigation nozzles.

The filter is a device for extending the working life of the unit.

The operation of the pump is possible in contaminated water, but this leads to an increase in the likelihood of breakdowns. This mainly occurs when solid particles enter from the bottom of a reservoir, well or other source. In the process of long-term operation, pipes become clogged, silt formations appear on various nodes that have contact with water, and wear of moving parts. An effective way to avoid this is to install filtration devices manufactured specifically for Malysh pumps. For example, the EFVP filter is St-38-12, it is easy to install, perfectly retains abrasive particles up to 150 microns in size.

The manufacturer, unfortunately, does not complete pumps with them when they are sold. You will have to purchase it separately, the price is low, about a hundred rubles. The filter will greatly increase the working life of the unit, eliminate blockages, and provide clean water.

The length of the water supply and the number of nodes

Although water will move horizontally through the system, losses in nodes and pipes cannot be avoided. Purchased equipment is recommended to be purchased with a power reserve of up to 20%.

These devices are also divided into two categories
:

• centrifugal
  having a higher price and better performance;
• vibrating
  that cost less and perform worse.

Vibratory pumps have a suction valve that can be located:

• at the top of the device;
• at the bottom of the device.

The ability to avoid the ingress of bottom mud, in the first variant, can be compensated by a problem in operation at a low water level in the well.

The second option has downsides - near the bottom, such a pump sucks clay, while the low water level will become an obstacle many times less.

The installation of vibration devices is not recommended in sand wells, which are considered to be all channels made to the depth of interstratal or groundwater.

Installation in a well or well

The submersible pump Kid is suspended on a synthetic cable. A metal cable or wire is quickly destroyed by vibration. Their use is possible if a synthetic cable is tied below - at least 2 meters. There are eyelets in the upper part of the case for its fixing. The end of the cable is threaded through them and carefully fixed. The knot is located no lower than 10 cm from the pump housing - so that it is not sucked in. The cut edges are melted so that the cable does not unravel.

The cable clings to a special eye

Connecting hoses and pipes

A supply hose is put on the outlet pipe of the pump. Its inner diameter should be slightly smaller (by a couple of millimeters) than the diameter of the pipe. Too narrow a hose creates an additional load, due to which the unit burns out faster.

It is allowed to install flexible rubber or polymer hoses, as well as plastic or metal pipes of suitable diameter.When using pipes, the pump is connected to them with a piece of flexible hose at least 2 meters long.

Installation diagram of a submersible vibration pump

The hose is secured to the nozzle with a metal clamp. Usually a problem arises here: the hose jumps off from constant vibrations. To prevent this from happening, the outer surface of the pipe can be processed with a file, giving it additional roughness. You can also make a groove for the clamp, but do not get carried away too much. It is better to use a stainless steel clamp with notches - it gives additional rigidity to the mount.

It is better to take a collar like this

Preparation and descent

The installed hose, cable and electric cable are pulled together, installing constrictions. The first is placed at a distance of 25-30 cm from the body, all the rest in increments of 1-2 meters. The straps can be made from sticky tape, plastic ties, pieces of synthetic twine, etc. The use of metal wire or clamps is prohibited - when they vibrate, they fray the sheaths of the cord, hose or the twine itself.

A crossbar is installed on the head of the well or well, for which the cable will be attached. The second option is a hook on the side wall.

The prepared pump is gently lowered to the required depth. Here, too, questions arise: at what depth to install the Malysh submersible pump. The answer is twofold. Firstly, from the water surface to the top of the hull, the distance should be no more than the immersion depth of this model. For the “Kid” of the Topol company, this is 3 meters, for the PATRIOT unit - 10 meters. Secondly, there must be at least a meter to the bottom of the well or well. This is so as not to disturb the water too much.

Tie with plastic, nylon cords, adhesive tape, but not with metal (even in a sheath)

If the Malysh submersible pump is installed in a well, it should not touch the walls. When installed in a well, a rubber spring ring is put on the body.

Having lowered the pump to the required depth, the cable is fixed on the crossbar

Please note: all weight must be on the cable, not on the hose or cable. To do this, when fastening, the twine is pulled, and the cord and hose are slightly loosened.

Installation in a shallow well

With a small depth of the well, when the length of the cable is less than 5 meters, to neutralize vibrations, the cable is suspended from the crossbar through a springy gasket. The best option is a piece of thick rubber that can withstand the load (weight and vibration). Springs are not recommended.

Mounting options for submersible vibration pumps with upper and lower water intake

Installation in a river, pond, lake (horizontal)

The Malysh submersible pump can also be operated in a horizontal position. Its preparation is similar - put on a hose, fasten everything with ties. Only then the body should be wrapped with a rubber sheet 1-3 mm thick.

Vertical installation option in open water

After the pump is lowered under water, it can be turned on and operated. It does not require any additional measures (filling and lubrication). It cools down with the help of pumped water, which is why switching on without water has an extremely bad effect on it: the motor overheats and can burn out.

Features of equipment installation

There are two pump mounting options:

1. The self-priming device is mounted next to the water source. A special submersible hose is lowered into the water at one end, and attached to the pump with the other.
2. The submersible device is attached to the pipe.If it is a flexible hose, then an addition to the fasteners can be a cable, which is attached at one end to the pump, the second to any stable element with a well. A flexible mounting option is preferable, as it allows you to adjust the immersion depth of the unit. The pump is completely immersed in water. Most of these devices do not tolerate dry operation. Therefore, it is always worth monitoring the level in the well or purchasing a pump with a float switch that will protect the device in the event of a lack or critically low water level.

It is recommended to install a check valve on the pipe itself, which will keep water in the system.

The submersible equipment installation algorithm includes how many points:

• All pipes are installed. If the pump will be installed on a rigid pipe, then it is recommended to put a small piece of flexible hose between it and the main channel for moving water into the house, which will dampen engine vibrations.
• The following are connected to the device: - a cable, - an electric wire, - a hose.
• The pump is smoothly lowered to the bottom of the well.
• When the unit touches the bottom, the entire structure should be raised to a height of half a meter to a meter from the point of contact.
• The cable must be firmly fixed, the wire connected to the network, the hose connected to the rest of the system and laid in the attachment channels.
• It is recommended to provide the upper hole of the well with a cover to prevent foreign objects and dirt from entering the system.

Electrical connection should be made only to a grounded source using a circuit breaker according to the following scheme:

During installation of the pump, you may need metal-fluoroplastic bushings

What parameters to consider when choosing

At a relatively low price, the technical characteristics of the Malysh submersible pump fully satisfy the needs of the modern user:

• operating voltage - 220W;
• productivity - 432 l / s;
• the presence of upper and lower openings for water intake;
• working depth - up to 40 m;
• power - 245 watts.

Varieties of models of pumps Kid

The price of the Baby water pump varies from 1000 to 2000 rubles, while it has good performance characteristics that allowed it to gain trust among users. In modern modifications, an additional built-in automatic protection system is installed. Automation protects the pump from overheating as a result of dry running, and also allows the engine to respond quickly to power surges in the network. This is very important for suburban areas, which can not always boast of a stable power supply.

Automatic water pump The kid turns off the power to the mechanism when the water level in the tank is low. The level is determined using a float system. When the water rises to a certain level, the pump motor starts again. The protection system operates from the same power source as the pump itself.

It should also be understood that in the modern market of pumping equipment there are several modifications of this unit.

Examples of immersing the pump Kid with upper and lower water intake into a well or well

Classic Pump Kid

The peculiarity of this model is that it is designed to supply water over a long distance.Classic Malysh effectively pumps water over 100-150 m, so it is often used for watering large summer cottages. The diameter of the hose for the Baby pump is 18-22 mm.

This model is not designed to work in a polluted environment, the permissible concentration of impurities should not exceed 0.01%. There are also requirements for the temperature of the pumped water - not higher than 35 ° C.

The basic model is not equipped with overheating protection, filter and pressure switch. And if the filter can still be installed on its own, then you will have to do without other modifications. Of course, all this directly affects the price of the unit, because it is much lower than other models. The base model can dive to a maximum of 5 m, and water is taken through the bottom valve.

Table of technical characteristics of pumps Malysh

Pump Malysh-M

This model, in terms of its technical characteristics, practically does not differ from the classical one, except that water is taken through the top valve. Therefore, this modification of the Malysh well pump is recommended to be used where the lower intake is not possible due to the high pollution of the bottom.

Kid-K

It has the same characteristics as the base model, but boasts built-in overheating protection. Such a model can be effectively used for long-term continuous work without supervision.

The device of nanosos "Malysh-M" and "Malysh-K" with an upper water intake

Baby-Z

The Malysh-3 submersible well pump is the most relevant for use in small wells. It is characterized by slightly more expensive than the base model, but it boasts significant structural differences:

The pump itself and the electric motor are enclosed in a monolithic sealed unit, which completely eliminates the ingress of water.
The rated power of operation is lower than that of the base model, and is only 165 watts. This is enough to work in a small well.
The unit produces 0.432 m? / hour at a pressure of 20 m.
The weight of the device does not exceed 3 kg.

Also, the pump of this model has a compact size, and it comes with a cable protected from water. The water filter is not included in the basic package, but it can be easily purchased and installed on your own.

The power of the vibration pump Malysh, depending on the model, ranges from 185 to 240 kW

Device with lower and upper water intake

"Baby" is one of the simplest and most affordable submersible devices today. It has been produced for a long time and has established itself as a high-quality and reliable device.

Materials for repairing the Baby pump can be bought at a specialized store and on the Internet

With its small dimensions, it can easily perform the following tasks:

• Provide water supply from sources with a diameter of up to 11 centimeters and reservoirs with a water temperature of less than 36 ° C;
• Pumping water from open reservoirs;
• Transport it from containers to domestic water supply;
• Fill the pools with water, drain it from there;
• Pump out liquid from flooded areas, such as basements.

It must be taken into account that the "Kid" pump can pump water with an extremely small amount of mechanical impurities.

"Baby" has three varieties that differ in technical characteristics and are used for various purposes:

1. Classical.The water intake of this model is lower, so it can easily cope with the supply of water from open sources located at a great distance. They can also drain flooded rooms, and pumping occurs to a minimum level. The ingress of dirt particles into the pump can damage it. The advantage of the device is the thermal protection function. The relay in the unit turns it off in case of overheating. On such a pump put the marking in the form of the letter "K". There are models marked "P". They differ in that their upper body is plastic. This is the most budget option. Models without this marking are made of aluminum. This is a higher quality and durable material.
2. "Kid-M". This is a top suction model. It is convenient for pumping from a well or wells. The advantage is that it can be used in polluted waters. This is due to the fact that during its operation, the debris will remain at the bottom and will not clog the unit. The engine in these devices cools better, this avoids overheating of the equipment.
3. "Baby-Z". This pump is also a top suction model. It is used for the same purposes as "Kid-M", but it is smaller and has less power and pressure. These properties allow it to be used for pumping water from shallow wells and small wells.

How to properly adjust

Often you come across such a position of installers that, they say, the set pressure of the relay at the factory is enough for the plumbing system to work comfortably and satisfy the requirements of the owner of the house. But, as life shows, having moved to your own private house, where a modern pumping station with a pressure switch is installed, the water pressure does not satisfy us (it is small).Asking a specialist to adjust the pressure in the system is useless (most often), so you should figure it out on your own.

So, the plumbing system at home most often consists of:

• Water intake point - this can be a village water pipe or a well with a submersible pump.
• Pressure switch with hydraulic accumulator.
• Water treatment in the form of a system of tanks and filters.
• Consumer.

How to properly adjust the pressure switch. Firstly, it is necessary to understand what pressure will be needed so that it is sufficient in the process of opening all points of consumption, especially for the soul, as the most powerful consumer. Secondly, it is necessary to know the pressure at the point of water intake. After all, how does the relay, and accordingly the pump. If the pressure at the intake point is below 1.4 atm, then the relay will not even turn on, that is, the pump will not work. This often happens if your private house is connected to the village water supply network, where the pressure most often does not rise above 1.0 atm.

If water is taken from a well or well using a pump, then the pressure in the home network will depend on the technical parameters of the unit. In any case, not lower than 2.0 atm. That is, you don’t have to worry that the relay will not turn on, so you can safely adjust it.

How to set the lower pressure limit

First of all, you need to adjust the lower pressure level. There are two nuts on the relay body. The first (it is larger) regulates exactly the lower level, the second is the difference between the lower limit and the upper one. We are interested in the first. With this nut, the state of the fixing spring is changed.When the nut is rotated clockwise, the spring is compressed, thereby increasing the lower limit of the water pressure in the system. When rotating counterclockwise - decrease.

Let's look at an example where there is a need to raise the upper limit, say, to 4.0 atm., And leave the lower limit within the factory limits. To do this, turn the large nut clockwise to the desired value. The smaller nut also rotates clockwise to the point at which the pump will turn on at a pressure of 1.4 atm.

True, this method, as practice shows, is not the most accurate. Moreover, in the factory settings, most often the spring of the small nut is practically weakened, so that it does not create the necessary pressure difference. Its optimal indicator is 1.0 atm., But in fact - 1.3 atm.

Therefore, it is worth adjusting in a different way. For example, equalize the pressure using a hydraulic accumulator (these are special expansion tanks for the water supply network, they are blue). True, this method is quite complicated and lengthy. In principle, you have to select the pressure using the “poke” method. That is, we set up the relay, inserted it at the water supply system, turned on the pump. If the indicators do not match, it is necessary to carry out a complete shutdown, drain the water from the expansion tank (from its lower part), bleed air from its upper part. And thus adjust the pressure parameters to the required ones. And this can take a long time.

There is another option, but for this you will have to remove the relay case and make an adapter, because testing and adjustment will have to be carried out not with water, but with air using a compressor. It is the pressure gauge of the compressor unit that will serve as an accurate reference point for the pressure in the device.At the same time, it is possible to carry out relay settings right there on the spot with the compressor turned on. It is convenient and fast, besides quite accurate.

And some more helpful tips.

• The pressure switch can only be connected to a grounded socket.
• The cross section of the supply electrical cable must correspond to the power of the pumping unit.
• It would be better if one more pressure switch with slightly higher pressure thresholds is installed in series in the electrical circuit of the house's water supply. Because the RDM 5 device often has contacts sticking.

Overview of popular models

There are two types of pressure switches: mechanical and electronic, the latter are much more expensive and rarely used. A wide range of devices from domestic and foreign manufacturers is presented on the market, facilitating the choice of the required model.

RDM-5 Dzhileks (15 USD) is the most popular high-quality model from a domestic manufacturer.

Characteristics

• range: 1.0 - 4.6 atm.;
• minimum difference: 1 atm.;
• operating current: maximum 10 A.;
• protection class: IP 44;
• factory settings: 1.4 atm. and 2.8 atm.

Genebre 3781 1/4″ ($10) is a Spanish-made budget model.

Characteristics

• case material: plastic;
• pressure: top 10 atm.;
• connection: threaded 1.4 inches;
• weight: 0.4 kg.

Italtecnica PM / 5-3W (13 USD) is an inexpensive device from an Italian manufacturer with a built-in pressure gauge.

Characteristics

• maximum current: 12A;
• working pressure: maximum 5 atm.;
• lower: adjustment range 1 - 2.5 atm.;
• upper: range 1.8 - 4.5 atm.

The pressure switch is the most important element in the water intake system, which provides automatic individual water supply to the house.It is located next to the accumulator, the operating mode is set by means of adjusting screws inside the housing.

When organizing autonomous water supply in a private house, pumping equipment is used to raise water. In order for the water supply to be stable, it is necessary to select it correctly, since each type has its own technical characteristics and features.

For efficient and trouble-free operation of the pump and the entire water supply system, it is necessary to purchase and install an automation kit for the pump, taking into account the characteristics of the well or well, the water level and its expected flow rate.

The vibration pump is chosen when the amount of water spent per day does not exceed 1 cubic meter. It is inexpensive, does not create problems during operation and maintenance, and its repair is simple. But if water is consumed from 1 to 4 cubic meters or water is located at a distance of 50 m, it is better to purchase a centrifugal model.

Usually the kit includes:

• operating relay, which is responsible for supplying and blocking voltage to the pump at the time of emptying or filling the system; the device can be immediately configured at the factory, and self-configuration for specific conditions is also allowed:
• a collector that supplies and distributes water to all points of consumption;
• pressure gauge for measuring pressure.

Manufacturers offer ready-made pumping stations adapted to specific requirements, but a self-assembled system will work most efficiently. The system is also equipped with a sensor that blocks its operation during dry running: it disconnects the engine from power.

The safety of the equipment operation is ensured by overload protection sensors and the integrity of the main pipeline, as well as a power regulator.
