The electrical control cabinet has protection functions such as overload, short circuit, phase loss protection, water leakage of the pump body, motor over-temperature, electric leakage, no lack of flashing and other protection functions, as well as single-pump and multi-pump control operation modes, main pump and standby pump switching modes and multiple starts Way. It can be widely used in industrial and agricultural production, water supply and drainage, fire protection, spray pipe network pressurization, HVAC cold and hot water circulation and other occasions.
Electrical control cabinets are widely used in the control of various electrical control cabinets, skyscrapers, residential pumps, fire pumps, sewage control cabinets, air-conditioning circulating pumps and other industrial, agricultural and municipal engineering related pumps. The control type is:
1. Temperature control: The temperature of the electric control box is controlled according to the constant temperature on/off of the electric control box in the heat exchange system.
2. Liquid level control: The control panel is equipped with a high-performance float switch, which can actively control the opening/closing of the electric control cabinet according to the change of the liquid level.
3. Pressure control: The external electric contact pressure gauge or pressure controller on the control panel of the electrical control cabinet can actively switch the electrical control cabinet with the change of the pipe network pressure. This water supply system is mainly used for daily fire fighting.
4. Time control: There are time setting buttons and flashing screen on the control panel of the electric control cabinet. Users can control the switch of the electric control cabinet according to their own time requirements. This type is mainly suitable for controlling various time organization or general intermittent operation methods.
The concept of electrical control cabinet programming is very important. For the problems that may occur during the operation of the equipment, it should be considered in advance, and pre-solutions should be used to solve them to achieve multi-faceted solutions. Each alarm display and operation shall be complete.
