Anhui plant pump save firearms and other supervisors

10 regions such as the total smoke was made in anhui 38 plants pump companies produced 45 batches of goods, pass the batch, 40 goods sampling pass rate was 88.9%, compared with 2007 goods sampling pass rate 82.9% move slightly. Including 14 batches of smoke was made in the Wells with water gun pass 13 batches, commodity sampling pass rate is 92.9%; A miniature power station was pump 22 batches, pass the 18 batch, commodity sampling pass rate is 81.8%; A sewage plant was made in the waste water pump 9 batches, pass the 9 batches, product sampling pass rate is 100%. Smoke examine results reaction sewage plant wastewater pump has good quality status in our province, Wells with shielding pumps and micro shield electric pump is common. Discord into engineering electric pump leads to cable provisions point unit efficiency, pump, pump flow point and Yang Cheng.

Well with power station with electric pump pump cable width than cable width is 2 meters long, micro pump power station cable width not less than 5 meters, pumps will lead to cable with lattice in the process is not convenient installation; Pump regulation point unit efficiency refers to the spray pump efficiency and the product of the efficiency of the motor, shaft with shielding pump is usually referred to as "the unit efficiency, micro power pump is refers to the commonly referred to as electric pump efficiency. Efficiency is the most critical nozzle in addition to the security indexes of quality indicators, its height is the cost, the direct relationship to the nozzle with grid use will cause resources stretched out. Traffic and Yang Cheng pump in use process is the most direct function coefficient, with commodity alternative meet the using requirements.

Causing a rift in the engineering case of important reasons: one is the enterprise to decline the cost and shorten the lead cable width of purpose; 2 it is reference enameled aluminium wire for copper wire as motor winding material, cause abrasion of stator growth, motor efficiency decline; Three is some small enterprise reference line diameter enameled wire or poor quality silicon steel sheet, copper consumption growth, iron loss increase, for the motor in the rated voltage is less than the rated power output, traffic and Yang Cheng alternative to standard, of course.
