Decay resistance pump self-priming pump shutdown after the matters needing attention

decay resistance pump self-priming pump shutdown after the matters needing attention of

when corrosion self-priming pump stop working for a long time, and the weight of the rotor pump impeller axis in one direction stress, easy to constitute axis twists and turns. Regularly disc pump, each time in the same direction will shaft rolling 120 °. To spare vertical corrosion self-priming pump, such as the outlet valve closed lax, high temperature medium within the export pipeline will go back inside pump, the stalling of pump shaft parts unevenly heated up and down, cause the pump shaft winding, so spare the decay resistance of self-priming water pump should be regularly dish pump.

1, if speed pump corrosion self-priming pump have abnormal sound, please check whether inhaled impurities present inside the pump body and impeller friction phenomenon.

2. If the environment is moist perhaps more acidic gas, environment temperature is higher, and all kinds of corrosive environment is too large, are not placed speed pump corrosion self-priming pump ambition environment.

3, removing motor maybe pneumatic motor, the device must first cut off power supply.

4, electric pump pump is necessary to use at an altitude of 1000 meters, more than 1000 meters above sea level when the motor must choose the plateau.

corrosion method of self-priming pump exhaust

there are kinds of corrosion of self-priming pump, but whatever the corrosion self-priming pump products needs to be able to bear or endure corrupt self-priming pump exhaust, commonly used method of corrosion self-priming pump exhaust has the following several kinds:

( 1) With hand pump may be small corrosion self-priming pump water filling some corrosion self-priming pump with a hand pump, also can buy or do small hand pump device at the inlet. With the hand pump water filling, corrosion self-priming pump outlet necessary device behind the valve gate valve closed, filled with a few water first force pump for water diversion, hand pump, such as water, said corrosion has been filled with water in the self-priming pump, able to work on.

( 2) In corrosion self-priming pump into the funnel is installed in place of outlet water filling. This method is to do a funnel, inserted in the hole is filled in the corrosion self-priming pump, from the funnel to corrosion in the self-priming pump water filling, but demand note is must be sealed when no irrigation method to deal with.

( 3) If it is diesel engine corrosion self-priming water pump can use diesel engine, exhaust water filling. When the diesel engine driven corrosion self-priming pump work, can use diesel engine exhaust effect vacuum filling water absorption, by machine inlet valve from corrosion self-priming pump suction effect on air in water. Using diesel engine exhaust extraction need to buy special ejector unit on corrosion self-priming water pump and diesel engine's exhaust pipe, by high-speed airflow when the exhaust ejector effect from corrosion self-priming pump in the air.
