What are the control modes of the pump control cabinet?

The pump control cabinet is an electrical function control cabinet that controls the operation of one or more pumps. Pump control cabinets are widely used in fire safety, industrial drainage, agricultural irrigation and other industries. There are many advantages and conveniences in using the pump control cabinet. The pump control cabinet has its own unique function. Shenzhen Xiangxiang will briefly introduce the function of the pump control cabinet.

As a fire pump control cabinet (fire control cabinet) for fire safety. The fire pump control cabinet is divided into a fire hydrant control cabinet, an automatic spray control cabinet and a fire pressure control water pump control cabinet, which can be divided into one use, one use, one use and one standby. When the work pump fails, the standby pump is automatically put into operation. The pump control cabinet consists of a fire button inside the fire box, a water flow relay, a pressure switch and a fire system control system. The pump control cabinet functions when the water source is not water.

As a life pump control cabinet (constant pressure water supply control cabinet). The life water pump control cabinet is divided into a liquid level control cabinet, a pressure control cabinet and a constant voltage frequency conversion control cabinet, etc., and can be divided into one use, one use, one use and the like. When the working pump fails, the standby pump is automatically put into use. The water pump control cabinet is controlled by the water level of the water tank, the pressure gauge control and the remote control system. The constant pressure water supply is the pressure of the pipe network through the remote pressure gauge or the pressure transmitter, and the output is 4-20 mA or 0-10V to the inverter. The frequency converter adjusts the pump speed according to the signal to meet the pump flow change requirements, thereby achieving constant pressure variable water supply and saving energy.

As a hot water circulation pump control cabinet. The hot water circulation pump control cabinet can control one or more pumps, generally using one and one standby. When the working pump fails, the standby pump is automatically put into use. The pump is temperature controlled or remotely controlled.

As the chilled water pump control cabinet, the pump control cabinet controls multiple pumps, and the main pump and the backup pump are used. When the main pump fails, the standby pump is put into use. The pump control cabinet has both manual and automatic modes of operation and can be selected via switches.

As a drain pump control cabinet. The pump control cabinet can be used for single level control, multi-level control and remote control. High water level start, low water level stop, super high water level start at the same time, automatic rotation work and other functions. The pump control cabinet is equipped with a number of signal indicators and feedback signal sources.
