DQBP variable frequency water supply equipment

Developed and produced by Zhejiang Dongquan Pump Industry Co., LtdVariable frequency water supply equipmentWhen the pipe pressure drops to the ON value of the pressure switch when the user uses water, the water pump automatically starts to increase the pressure and deliver water; When the water supply is stopped and the pipe pressure reaches the OFF value of the pressure switch, the water pump will automatically shut down. When using water, the motor starts smoothly, and the frequency converter senses the water pressure based on the feedback from the pressure sensor, thereby controlling the motor operating frequency and continuously changing it to reach the set speed. The water pressure is used to maintain a stable pressure at the set value.

DQBP variable frequency water supply equipmentPurpose:

1. Apartment, residential, villa water supply, rural household water supply;
2. Factory water supply, water supply system, drinking water system;
3. RO water treatment, supermarkets, motels SPA、 Beauty salon.

Applicable liquids: pure water without impurities, clean, thin and non corrosive neutral liquids.

DQBP variable frequency water supply equipmentUsage conditions:
Environmental temperature: Max.+40 ℃

Liquid temperature:+2 ℃~+90 ℃

Inlet pressure: set value

DQBP variable frequency water supply equipmentProduct Advantages:

1. Constant pressure and stabilization: When in use, the pressure will not exceed the set pressure value, and the water supply will remain stable even if the water consumption exceeds the constant pressure range.

2. Water free power outage: When the water source is dry, the water pump automatically shuts off and attempts to start on its own until normal water supply is achieved.

3. Water stop shutdown: When water is stopped, the microcomputer automatically detects and controls the motor to slow down and shut down.

4. Leakage compensation: When there is leakage or dripping in the pipeline, the microcomputer automatically detects and operates the water pump to compensate for the pressure to the set value.

5. Differential pressure switching: In case of abnormal function of the pressure transmitter, it can be switched to the differential pressure function to avoid water shortage

DQBP variable frequency water supply equipmentAutomatic switching of pressure tank operation function during low flow:

Some water supply systems have low or no water flow at night, and if the equipment continues to operate continuously, it can cause problems such as reduced equipment efficiency, high energy consumption, and equipment wear and tear. To improve this unfavorable working condition, a small air pressure tank can be connected in parallel in the equipment system. When the flow rate is low, the water supply can be operated intermittently in an air pressure tank manner, and normal operation can be resumed when the water supply flow rate in the system reaches a certain level.
