Shandong Hairui Zhonglian Pump Industry Co. , ltd. The centrifugal pump that is a major produces manufacturer. When type selecting of client centrifugal pump, manufacturer of my company water pump can provide the before-sales service such as price of centrifugal pump model, centrifugal pump, in order to offer client reference, and manufacturer of my water pump can provide the service of product of custom-built pump industry for the client. This product information is the knowledge that the circumstance can cause electric machinery of centrifugal pump burn down about what:

Centrifugal pump burns electric machinery to basically have the following reason:
Above all, making clear Hunan electric machinery is burned first was to burn bearing (mechanical failure) still burned coil (electric breakdown) .
If be the breakdown that burns coil, basically cause, exorbitant or voltage is too occasionally low also can cause coil calorific short circuit, check the voltage when moving to be differred with rated voltage first so too much.
Cross voltaic short circuit, the likelihood has the following reasons:
1, centrifugal pump excess load moves, make electric machinery is in for long rated electric current or decide electric current to move above quota. What should notice particularly is, the 3-5 that the starting electric current of electric machinery is rated electric current times, ought to avoid to start as far as possible soCentrifugal pumpBear or full load are taken to move when (the rated electric current that basically should read electric machinery and of normal moving electric current match surplus) .
2, the mechanical failure of centrifugal pump causes electric machinery to pass negative charge, electric current is too big and burn coil.
3, of electric machinery medicinal powder heat gives an issue. Coil of general electric machinery uses wind cold case, sumbersible pump is water-cooling crust. If broke cooling water (air) , make coil cannot come loose hot, likely burn down coil.
4, electric machinery works in damper working environment. The right insulation that ought to check coil before electric machinery is started and alternate with are isolated from, insulation of grade of different use voltage asks to also differ, can consult to be checked about national level. What ought to notice electric machinery in the moving process of electric machinery is waterproof and moistureproof.
The lift of centrifugal pump is to use those who overcome height and resistance, the pump of soar Cheng nods his discharge when the job in soar Cheng is the discharge that designs a place, if be when low lift job, the exit obstruction that is equivalent to centrifugal pump is reduced, at this moment the discharge of centrifugal pump can increase, electric machinery is met excess load, exceed certain level to be met burn down electric machinery. The exemple is consistent the lift of pump of stage water supply is 50 meters, discharge is 50 stere / hour, go to when it of water supply of 50 meters of altitude when, its discharge is 50 stere / hour, go to when it when water supply of 40 meters of altitude, its flow that reduced it with obstruction highly may achieve 80-90 stere / hour above, at this moment electric machinery can give out heat or burn down.
Thank you very much to Shandong Hairui Zhonglian Pump Industry Co. , ltd. The visit of official website! Above is the introduction that the circumstance can cause electric machinery of centrifugal pump burn down about what, still think to this problem like you deep one pace understanding, or the problem that has price of model of type selecting of product of other pump industry, water pump, water pump, water pump needs to solve, contact this water pump manufacturer please, my company still produces fire pump, welcome you at any time seek advice.
