Programs aimed at energy conservation and rational use in the current conditions of economic development play a huge role. The more efficient the equipment is, the better it affects finances. If the device at the same time consumes little energy, then the savings increase. Such technologies have recently become increasingly popular. This applies to pumping stations, which are a whole group of devices responsible for control.
Such equipment works automatically, so the control unit is equipped with electrical and technological protection. The submersible pump control station "Cascade" stands out among the rest. It can be used for automatic or manual control, and works as a shield protecting a three-phase electric motor. Such a unit is used to increase pressure, drainage. This equipment has also found distribution in the conditions of water supply systems. This may include artesian wells.
Features of use
Submersible pump control stations provide trouble-free operation, because the devices are equipped with a whole set of protection and control of the microprocessor-based electric motor. It guarantees trouble-free and durable operation of a three-phase electric motor. The pumping station and submersible pump, which were equipped with similar devices, gain new opportunities. For example, the performance of certain functions is provided by the water intake system, which allows you to control the operating current, emergency condition and quickly configure the protection of the electric motor.
If an accident occurs, then with the help of this equipment it will be automatically reset, after which the mechanism will restart with a delay in time. The Stop and Start buttons are located on the front panel, with their help you can control the station in manual mode. The rise of water and its drainage are carried out automatically, while taking into account the level of liquid captured by pressure sensors.
Electric motor protection with control station
Submersible pump control stations provide engine protection if a low debit of an artesian well is noted. Protection will be applied in case of engine idling, which occurs when the connection between the engine and pump part is broken. Protection is guaranteed when several or one phase is broken.
Short circuits can occur in the electric network, the protection in this case will also work, as with the asymmetry of the voltage that feeds the mechanism. Such submersible pump control stations are located in special metal cabinets or drawers, the doors of which have a rubber seal. The cabinet can be locked and its housing meets IP-54 protection level.
Description and subtleties of station management Grundfos
One of the most common today is the station brand Grundfos. Its main purpose is to increase the pressure in hydraulic systems in the process of water intake and pumping water in a circulating way. Water is taken from:
- storage tanks;
- wells;
- water supply network.
Such submersible pump control stations provide wide operational possibilities. The enclosures are small in size and allow the installation of equipment in confined spaces.
The device guarantees ease of use and provides automation of the control system. You can find information on operating modes by looking at the control panel, which is very convenient for viewing. Automatic operation is guaranteed by a temperature regulator, pressure and flow switches, as well as an integrated membrane tank. During water intake, the unit is switched off and on automatically.
The need to use a control station
Most often, the ECV submersible pump control station is used to maintain a certain pressure in the pipeline. Using such equipment, you can maintain the water level in a water tower or tank.
A similar device is used to control several units that are involved in a hot or cold water supply system. Such systems are used to control several or separate fecal or drainage electric pumps in order to control the liquid level in the basement, well or tank.
Use of the control system for the pump control system
Centrifugal pumps, which are installed in well conditions, also need to be controlled and protected. For them, special stations are used, which were mentioned in the subtitle. They can be operated in enclosed spaces where the temperature of the external air varies from -45 to +40 ° C, while the relative humidity can be kept at 98% or lower. Such conditions are true for a temperature of +25 ° C. Such control stations provide the system with certain functions, among them:
- water level control;
- motor shutdown;
- dry sensor monitoring;
- restoration of an operating mode;
- engine blocking.
QK Control Station Application Features
An excellent control station for submersible pumps is the QK model. It is intended for single-phase equipment, the engine power of which can vary from 0.37 to 2.2 kW. Children should not be allowed to approach the device; they should not be touched when it is turned on or off. Children must not touch the wiring of the pump.
The device operates exclusively in automatic mode, manual control is not possible. By turning off the electrical power, you can connect the station. If the pumping station and the submersible pump were equipped with the described system, and during operation you noticed the occurrence of the same type of errors for a short time, then appropriate measures must be taken to correct the situation.
First, reset using the button and restart the system. As soon as you notice the flashes of indicators, you can be sure that the equipment has rebooted. You can select the pump operating mode using the switch, which is located on the electronic board. The pump must be powered by connecting a pressure switch to the pump terminals.
