After the pump starts the screw pump, the reason of the pump pressure high current low diaphragm pump is:
(1) the outlet valve of the pump is not opened or the gate is falling off:
(2) the line pressure of the water injection dry gear pump is high S
(3) the pump pressure meter and the ammeter are not allowed,
(4) the coin flow valve was killed.
How is the f pump and the name electric Shenyang store after the water injection
Answer: after the pump starts, the high current of the pump is low.
(1) open the pump gate valve, if the sluice board is lost or the single flow valve is killed,
Risk repair,
(2) check the instrument, stop the pump to replace the instrument,
(3) reporting and scheduling, adjusting the pressure of the external network.
The cause and place of the pump pressure low or no water after the water injection mulberry is fixed
What are the methods of reason?
Answer: Causes and treatment methods of pump pressure low or no water after injection of water pump
There are the following JL cases.
(1) phenomenon: the pump pressure is very high, the current is small, the pressure is normal, no water.
Cause: the outlet valve did not open, the gate fell off, and the outlet pipeline was blocked.
Treatment: overhaul or replace the outlet valve and remove the blockage of the outlet pipeline.
(2) phenomenon: low suction pressure, low pressure and fluctuation of pump, no water.
Reasons: import negative open, sluice sluice, inlet filter plugging
