The welcome visits Shandong Hairui Zhonglian Pump Industry Co. , ltd. Website, the sumbersible pump that my company is a major produces manufacturer. When you need sumbersible pump type selecting, we will provide the before-sales service such as price of sumbersible pump model, sumbersible pump, in order to offer your referenced alternative. This product information is the knowledge that should notice about sumbersible pump choose and buy functional sex is divisional:
If cannot make in-depth inspection to sumbersible pump, how does that do simply probably judge? Staff member basis is old experience, undertake as follows arranging to point of sumbersible pump visual examination:
Sumbersible pump product is a kind of machinery carrying water that slips into underwater movement. Basically small-sized sumbersible pump, sewage contamination sumbersible pump, well uses a few sort such as sumbersible pump and pump of report of phreatic water screw model. Sumbersible pump structure compact, installation is convenient, use convenient, the whole when the job is located in underwater, moving noise disappears in underwater, do not hear aircrew noise almost, improved working environment greatly. At the same time electromotor underwater moves, medicinal powder hot condition is good, can improve electric machinery efficiency, prolong electric machinery service life. Be used extensively irrigate at farm, sewage eliminates and drinking water is carried wait for a respect.
One, purchase sumbersible pump note:
1, the choice of manufacturer home:
Choose sumbersible pump, want recognize water pump to produce manufacturer above all, clear shop sign and product certificate of approval should view above all when choosing pump, cannot buy 3 without the product, do not have manufacturer home namely, without production date, without manufacturing licence.
2, the choice of the type:
1) when choosing a well to use sumbersible pump, 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) with 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) use 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) use 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.
5) when should be being 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 choice of single-phase pump or three-phase 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.
4, norms choice:
Of different specificationsSumbersible pumpHave different scope of application. The flow that provides on the nameplate of an any sumbersible pump and lift are the rated operating mode that this sumbersible pump uses, also be the point with use higher efficiency commonly.
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.
5, the examination of water 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 be isolated from to electric machinery
Undertake metrical, measure insulation resistance to must shake namely with million Europe watch watch, cannot use a list, because the span of the 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.
6, the option that buys a place. Want to notice the point of sales that agriculture machinery branch approbates or brand shop are bought.
2, note of use sumbersible pump
1, a few necessary inspections should make before starting to sumbersible pump: The rotational circumstance of pump shaft is normal, have do not have calorie of dead phenomenon; The position of impeller is normal; Cable and cable outlet have crack-free, abrade and break off the phenomenon. Carry
Should notice to observe the metabolic condition of voltage in travel, ordinary control is in of rated voltage losing less than of 5 ％ limits. Additional, position of water pump underwater is very significant, answer to choose abundant, good without silty, water quality in water quantity place as far as possible, hang down
Straight suspensory in water (attention: Ten million cannot use cable suspensory) , do not allow a horizontal stroke to put, lest be immersed in mud medium or be jammed by suspension content water pump entrance, and bring about acute of quantity giving water to decrease smoke even do not sail upstream come.
2, water pump maintenance is become once water pump appeared breakdown, him avoid by all means starts work disassemble. When disassembling because of oneself, it is not to know to breakdown is in where and be caused tear open in disorder blindly; 2 be do not have special tool and often damaged original and in good condition
Component. Good idea is to arrive the experience, maintenance that has dimensions nods maintenance, change in time overage component and certain and fragile. Below normal circumstance, every half an year should maintain water pump.
3, the electric pump of long-term out of service, should carry water pump in time from fountainhead, side by side the seeper inside empty pump, be in especially cold winter. Set its dry office next, conditional user also can be on the key place besmear of water pump butter, in the axis
Bear inside add lubricating oil, in case component is rustily. Additional, the blame operating period of water pump, be not grow better more. If be not used for long, not only extremely easy rustily component, return the service life that can reduce water pump.
Thank you to be mixed to the visit of above content very much read! This information is the introduction that should notice about sumbersible pump choose and buy functional sex is divisional, if you still want to have farther knowledge to this problem, or want to buy this relevant product, contact personnel of my company customer service directly please, my company returns production to suck pump oneself, welcome you at any time seek advice.
