How to select sumbersible pump kind?

Shandong Hairui Zhonglian Pump Industry Co. , ltd. The sumbersible pump that is a major produces manufacturer. When type selecting of client sumbersible pump, manufacturer of my company water pump can provide the before-sales service such as price of sumbersible pump model, sumbersible 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 about how choosing the knowledge of sumbersible pump type:

One, the choice of sumbersible pump or sumbersible pump
Answer to decide to use single-phase pump or three-phase pump according to circumstance of local power source, the place that always has three-phase power supply should choose three-phase pump commonly. Because be compared with the single-phase pump of norms and three-phase pump photograph,this is, three-phase pump housing accumulates small, weight vibration is light, light, choose three-phase pump so relatively economy.
2, the choice of sumbersible pump type
1. chooses a well to useSumbersible pumpWhen, should the diameter according to the well (100mm, 150mm, 200mm, 250mm, 300mm) the baseplate date of affirmatory report pump, choose its according to the actual flow of the well, lift again specific norms model.
2. uses Yu Jian well, river, laky when waiting for place of ordinary clear water to take water, but preferential choose QY model, Q with QS model etc on pump sumbersible pump.
3. is used at local district catchment, impurity of little grain solid is contained in water quality, if construction of flood prevention drain flooded fields, building, farm is purified,wait, choose QX model, QDX etc next pump sumbersible pump is more appropriate.
4. is used at carrying to contain the foul water such as solid grain and contamination, when the foul water that contains big grain contamination especially, should choose sumbersible pump of WQ sewage contamination.
When 5. should be used at the mining area excavate such as the colliery to carry the foul water that contains the solid grain such as contamination, coal fines, must choose can of explosion proof lie between explode model mine uses sumbersible pump, do not use general sumbersible pump, lest produce explosive risk.
3, the examination of sumbersible pump quality
The electric machinery of sumbersible pump has the structure such as type full water, type full oil and screen type. Before be being used to filling water type pump, must twist bolt of two affusion aperture entirely below, an affusion (without Sha Shui) , another discharges air, need after affusion static wait for the left and right sides 15 minutes, etc the air inside electric machinery antrum adds clear water again after all eduction, until after adding full water screw 2 affusion bolt again. Make electric machinery is in encapsulated situation. After electric machinery fills water, in winding job Yushui, can undertake metrical to electric machinery insulation, measure insulation resistance to must shake namely with million Europe watch watch, cannot use all-purpose list, because the span of all-purpose watch is finite, not clear to block value is isolated from to measure between winding and earth. After insulation is eligible, undertake trying moving detecting to water pump. Conditional place, after full water is added inside electric machinery, screw affusion bolt, can be pump inside cistern electrify test run, but cannot run for long, do not have a condition the idling can be done on the well, but time must not exceed 3 seconds.
4, choice of sumbersible pump norms
The sumbersible pump of different specifications has different scope of application. AnySumbersible pumpthe flow that provides on nameplate and lift are the rated operating mode that this sumbersible pump uses, also be use efficiency is taller commonly relatively fine point.
In using, change as discharge, lift happening, the efficiency of sumbersible pump and electromotor power also produce change accordingly, the economy that uses to sumbersible pump and dependability have certain effect. Be like use lift too low, overheat of dynamoelectric opportunity, move for long to be able to burn out even electromotor; Be like use lift exorbitant, criterion water pump discharge is met decrescent, loss of efficiency.
Sumbersible pump can be in commonly 0.7 times ～ moves normally inside the rated discharge limits of 1.2 times. Accordingly, when requirement user is choosing and using sumbersible pump, must consider likely scope of application, be opposite especially the sumbersible pump of soar Cheng, do not make its are nodded in too low lift move, waste electric energy already otherwise, may damage again sumbersible pump.
