Pump control stations, their application

Programs aimed at conserving energy andrational use, in modern conditions of economic development play a huge role. The more efficiently the equipment works, the better it affects the finances. If the device at the same time consumes little energy, then the economy increases. Such technologies have recently become more popular. This applies to pumping stations, which represent a whole group of devices responsible for management.

This equipment works automatically,therefore the control unit is supplied with electrical and technological protection. The control station of the submersible pump "Cascade" stands out among the others. It can be used for automatic or manual control, but works as a shield protecting a three-phase electric motor. This unit is used to increase pressure, drainage. This equipment has also spread in the conditions of water supply systems. Here it is possible to carry artesian wells.

Features of use

Control stations for submersible pumpsensure trouble-free operation, because the devices are equipped with the whole set of protection and control of the motor based on the microprocessor. It guarantees trouble-free and durable operation of the three-phase electric motor. The pump station and the submersible pump, which were equipped with similar devices, acquire new opportunities. For example, certain functions are provided by a water intake system that allows you to monitor the operating current, emergency state and quickly adjust the protection of the electric motor.

If an accident occurs, then it isequipment will be reset automatically, after which the mechanism will restart with time delay. On the front panel there are buttons "Stop" and "Start", with their help you can manage the station in manual mode. The water is lifted and drained automatically, taking into account the level of fluid trapped by the pressure sensors.

Protection of the electric motor by means of a control station

Control stations for submersible pumpsProvide engine protection if a low level of artesian well debits was noted. The protection will be used in the case of idling the engine, which occurs when the engine-pump connection is broken. Protection is guaranteed when several or one phase is broken.

In the electrical network, there may be shortthe protection in this case will also work, as in the asymmetry of the voltage that the mechanism feeds. Such control stations for submersible pumps are located in special metal cabinets or boxes, the doors of which have a rubber seal. The cabinet can be locked, and its housing corresponds to the level of protection IP-54.

The description and subtleties of the management of Grundfos station

One of the most common today is thestation of the brand Grundfos. As its main purpose is the increase in pressure in hydraulic systems in the process of water intake and pumping water circulating. The water is taken from:

• storage tanks;
• wells;
• water supply network.

Such control stations for submersible pumpsprovide a wide range of operation possibilities. The cases are small in size and allow the installation of equipment in confined spaces.

The device guarantees ease of use andprovides automation of the control system. Information on the operating modes you can find by looking at the control panel, which is very convenient for review. Automatic operation is guaranteed by a thermoregulator, pressure and flow switch, and an integrated membrane tank. At water intake, the unit is switched off and on automatically.

Need to use a control station

The most common control station is a submersibleThe ECW pump is used to maintain a certain pressure in the pipeline. With the help of such equipment it is possible to maintain the water level in the water tower or tank.

A similar device is used to controlseveral units that are involved in the conditions of a hot or cold water supply system. Such systems are used to control several or separate fecal or drainage electric pumps in order to monitor the level of liquid in a basement, a well or a container.

Use of the control station pumps CPS

Centrifugal pumps, which are installed inwell conditions, also need to be managed and protected. They use special stations, which were mentioned in the subtitle. They can be operated in closed rooms, where the temperature of the outside air varies from -45 to +40 ^aboutC, while the relative humidity can be kept at 98% or lower. Such conditions are true for a temperature of +25 ^aboutC. Such control stations provide the system with certain functions, among them:

• water level management;
• switching off the electric motor;
• dry-running sensor monitoring;
• restoration of the operating mode;
• blocking the engine.

Features of the QK control station application

Excellent control station for submersible pumps- model QK. It is intended for single-phase equipment, whose engine power can vary from 0.37 to 2.2 kW. The device should not be allowed to approach children, they should not be touched in the switched on or off state. Children should not touch the pump wiring.

The device functions exclusively inautomatic mode, manual control is not possible. By disconnecting the electrical power, you can connect the station. If the pump station and the submersible pump have been equipped with the described system, and during operation you notice the occurrence of the same type of faults within a short time, it is necessary to take appropriate measures to correct the situation.

To start, reset the settings from theusing the button and restarting the system. Once you notice the flashes of the indicators, you can be sure that the hardware has rebooted. You can select the mode of operation of the pump using the switch that is located on the electronic board. The pump must be powered by connecting the pressure switch to the pump terminals.
