Pump Control Panel
Pressure control type pumps are mainly used in household water supply, fire fighting pressure stabilization, air-conditioning water pump system and production process water, etc. Generally, electric contact pressure gauges and pressure switches are equipped to set upper and lower limit of working pressure. It starts when pipe network’s pressure is lower than lower limit, and stops when pipe network’s pressure reaches upper limit. Pressure range between upper and lower limit cannot be too little. Otherwise, equipments will be caused to start & stop frequently, affect motor system’s performance and cause motor faults. Pressure stabilizing measures are commonly taken to reduce pressure fluctuation such as pressure tank in order to ensure the system’s normal operation.
