Pit pump turn what are the reasons for points

pit pump failure and the reason analysis of

1, fault: there are insufficient flow pressure or pressure

: the manual pressure relief valve sealing, pressure regulating spring fatigue; Nozzle holes and wear.

solutions: repair; Replacement.

2, fault: sudden high pump pressure

why: relief valve failure, pressure relief valve failure, system failure.

solutions: check repair troubleshooting.

3, fault: running noise big impact sound

why: crankshaft crank and bearing wear, clearance is too large, mobile connecting rod bolt; Gear pump with sundry, damage; Liquid absorption.

solution: replacement, tight; Clean, replace; Check.

4, failure: plunger seal leaking serious

why: seal wear or damage; The plunger surface hair cut.

solution: replace the seal; Replace or repair the plunger.

the analysis of the causes of pit pump turns motionless

do you know why in the diving sewage pump or use a new buy diving sewage pump will inevitably encounter pit pump turns motionless phenomenon, and encounter the phenomenon when I don't know what is the cause of the authentic pit pump turns motionless, here is your share of all kinds of pit pump turns motionless:

1, the pit pump turns motionless is likely a factor: the use of submersible sewage pump with stir function if it is automatically stir sewage pump, is likely to be conveying liquids which contain fiber and other groceries winding to the above or plugging into the water pump body, impeller pit pump turns motionless phenomenon.

2, pit pump turns motionless reason may be the cause of the damage caused by pit pump bearing, the pit start appear stuck pump and a pump control cabinet, the phenomenon of the trip, then should replace new bearing.

3, pit pump turns motionless and may be the cause of transport corrosive liquid of ordinary cast iron drainage pump is easy to corrode, impeller nut loose after corrosion, cause the impeller and pit pit due to pump pump pump body contact switch, suggest that choose stainless steel material made of stainless steel pit pump products.

4, replacement after a new bearing or a phenomenon, when pit pump turns motionless and may be the cause of pit of pump motor rotor, as a result of the motor rotor diameter slightly a little coarse make it difficult to turn the phenomenon in the pit of pump motor, the problem can be to change the new motor rotor or take down the old motor rotor and the lathe car 30 microns can solve above pit pump turn phenomenon.
