Small variable frequency water supply pump unit

Small variable frequency water supply pump unit
Small frequency conversion water supply pump unit is applicable to: apartment, residence, villa water supply, factory water supply, water supply system, drinking water system, RO water treatment, supermarket, motel and spa.
Small variable frequency water supply pump unit -- Product Introduction
For small frequency conversion water supply unit, when the pipe pressure drops to the on value of the pressure switch when using water, the water pump starts to pressurize and supply water by itself; When the water is stopped and the pipe pressure reaches the off value of the pressure switch, the water pump will shut down automatically.
Purpose of small frequency conversion water supply unit: apartment, residence, villa water supply, factory water supply, water supply system, drinking water system, RO water treatment, supermarket, motel and spa.
Applicable liquid: clean water without impurities, clean and thin neutral liquid without corrosiveness.
Small variable frequency water supply pump unit -- service conditions
Ambient temperature: max. + 40 ℃
Liquid temperature: + 2 ℃ ~ + 90 ℃
Inlet pressure: set value
Small variable frequency water supply pump unit -- Product Description
When using water, the motor starts smoothly, and the frequency converter senses the water pressure according to the feedback of the pressure sensor, so as to control the operating frequency of the motor, change it to reach the speed continuously, and maintain the water pressure at the pressure setting value stably.
Constant pressure and pressure stabilization: when in use, the pressure will not be higher than the pressure setting value, and the water consumption exceeds the constant pressure range, and the stable water supply will still be maintained.
No water and power off: when there is no water source, the water pump will automatically cut off water and try to start it by itself until the water supply is normal.
Water stop shutdown: when the water is stopped, the microcomputer automatically detects the return and controls the motor to slow down and stop.
Leakage detection and compensation: the microcomputer will automatically detect and operate the water pump to compensate the pressure to the set value.
Differential pressure switching; In case of abnormal function of the pressure transmitter, it can be switched to the differential pressure function to avoid no water.
