Submersible pump for wells with control: types and working principles

Submersible pump in the well will provide uninterrupted water supply

Purpose and types of pumps for pumping water from wells and wells

All pumps of the submersible type provide water rise to the surface with a certain depth which depends on the power unit, and its delivery to the consumer. A distinguishing feature of such pumps is that they are omitted partially or completely in the water column. Two different types of submersible pumps can be distinguished by the principle of action for well. With or without automation it, they are:

• vibration. The basic operating member of these pumps is a movable piston, which generates the water pressure during its reciprocating motion. It is provided by the electromotive force of the inductor, to which the core is rigidly attached through piston rod. The coil is current voltage of 220 V, which generates a magnetic field causing movement of the core together with the piston. When retracting the piston in the working chamber flows into the water. After reaching the limit point, the piston opens the contacts and the magnetic field is shut off. Under the action of the spring force presses the piston with the water, creating a pressure. This process is constantly repeated by raising the water at the desired level. These pumps are not very thick, but nice to cope with muddy water and small stones without significant damage to their health. they are not expensive, about 20 - 25 USD The piston can be replaced independently without much difficulty;

Wiring centrifugal submersible pump

Any of these types of units can be equipped with an automatic control system that allows you to turn the unit already when opening the tap.

Useful advice!If the water in the well or downhole turbid or small stones caught therein to 2 mm, it is better to choose vibrating pumps. They are less susceptible to such pollutants. In this case, you need to know that their power is in 2 - 3 times lower than that of the centrifugal.

Submersible pump for wells with automatic

Recently, growing in popularity gaining submersible pumps for wells with automation. This is no accident. After all, people have always sought to make their lives easier by inventing these or other mechanisms. Strictly speaking, to create an automatic water supply system little one pump and hoses. We need additional equipment. Such equipment may include: an electronic control unit, accumulator, various sensors, the protection device against overheating and low water filters.

Submersible pump for well

Let us consider all of these elements in more detail. The control unit is used for receiving and processing signals from the various sensors. His task is switched on and off the pump in certain situations. The accumulator is a sealed bottle, can withstand high internal pressure. It is a membrane connected to the sensor. It is triggered when the pressure is lowered below the critical value. In this equipment comprises a pump which fills the water bottle. When the pressure is raised to a necessary - the pump turn off. It is this mechanism to ensure that the pump does not run continuously, joining at each tap is opened. This greatly increases the life of the entire system and creates a stable pressure in the water.

Sensors are used for readout with certain parameters. Water pressure sensor determines the rate in the water. Sensor "dry run" protects the pump from overheating. He works in the off when released into the air system, indicating that the water level drops. The water level sensor provides disabling pump at the critical water level is lowered. It is mounted on floats of centrifugal pumps.

Design and operation of an automatic water supply system

To submersible pumps for wells with automatic run smoothly the whole system must be mounted properly. A device such her in the well or well in the water column or on the float located pump. From him comes the pipe in which the nipple and check valveThat does not allow the water to flow down. The pipe is connected with the crosspiece on the surface and through the check valve and nipple. It is a pressure sensor connected via a flexible liner to the control unit.

From one cross pipe goes to the pressure accumulator, and the other to all consuming elements: faucets, toilets, soul, washing machines and other household appliances. The wire is connected from the pump outlet through the control unit. The block itself is connected to network 220 via circuit breakers, calculated on the current strength of 10 to 16 amperes. This parameter depends on the capacity of the equipment. Circuit breakers provide protection for automation and pump overload in the network.

Submersible pumps for wells

Submersible pumps for wells with automatic work as follows: when you first start pump pumps water a pressure accumulator via a check valve and filter, until the pressure therein reaches a maximum. The pressure sensor is activated and sends a signal to the automation of the pump shutdown. The system is now ready for use. Including faucet or appliance water consumption, we enable water under pressure out of the accumulator. Water therein may be from 30 to 100 liters.

Useful advice!Buying pressure accumulator, it should be understood that the amount of water are put into it, approximately 2 times smaller than the volume of the entire device. This is due to the fact that all the free space above the membrane is filled with air.

When most of the water will, by the spring diaphragm will increase the volume of the chamber with air, which reduces the pressure. When critically low level sensor will give a signal to the control unit to switch the pump. Water, filling the accumulator, again increase the pressure and the cycle can be repeated again and again.

How to choose submersible pumps for wells with automatic

When choosing a submersible pump for wells with automatic deciding what should be, how high it should raise the water and how far its supply. These settings are reflected on the packaging and in the instructions. For small to 20 m. The wells can be any pump if the water is supplied not too far. In the case where the distance to the consumer not more than 50 m, the pump must buy a lifting height of not less than 20 m. The distance from 50 to 100 m. Makes use lifting device with a height of 40 m.

Scheme of immersion pump with automatics

Pump selection depends on the purity of the water. The purified sand and small impurities well, possible to use any pumps, and contaminated only vibration.

Useful advice! If you plan to build a permanent water supply, it is best to purchase a pump with the upper wall of water. This allows the pump does not overheat at strong lowering of the water level and not to dial a sand or silt. The pump will "swallow air," and it will turn off automatic.

Mounting submersible pump

The volume of the accumulator should be selected based on the needs of the family. At a low enough water consumption of 50 - 60 l and with a significant need to acquire the cylinder capacity of at least 100 liters.
