Why can be blowdown pump efficiency reduced slowly?

The welcome visits Shandong Hairui Zhonglian Pump Industry Co. , ltd. Website, the blowdown pump that my company is a major produces manufacturer. When you need blowdown pump type selecting, we will provide the before-sales service such as price of pump of blowdown pump model, blowdown, in order to offer your referenced alternative. This product information is the knowledge that why can reduce slowly about blowdown pump efficiency:

Blowdown pump is a kind of pump and electric machinery join system, the pump that slips into the job below fluid at the same time kind product, compare with general horizontal pump or vertical sewage pump, blowdown pump structure is compact, cover an area of an area small. Installation maintains pump of convenient diminutive blowdown to be able to be installed freely, largeBlowdown pumpDeserve to automatic lotus root adds up to device to be able to undertake be installinged automatically commonly, installation and maintenance are quite convenient. Successive movement time is long. Blowdown pump because pump and electric machinery coaxial, the axis is short, rotational component weight is light, because of load of the susceptive on this bearing (radial) relatively lesser, life should grow more than general pump. Nonexistent cavitation destroys the problem such as the pilot a ship into a harbour that reach fill. Especially hind to the operation personnel brought very big convenience. Oscillatory noise is little, electric machinery temperature rise is small, to environmental free from contamination. Blowdown pump basically includes: Pump of phreatic water blowdown | Take cut sewage to promote pump | Pump of stainless steel blowdown | Suck type blowdown pump oneself | Without jam blowdown pump | Pump of report of family expenses dive | Tear off type blowdown pump | Explosion proof goes corrupt pump, main type has the series such as QW, WQ, JYWQ, JPWQ, WQK/QG, AS/AV, GW, LW, ZW.
Blowdown pump loss of efficiency is main reason:
1. casts blemish, cavitation erosion, abrasion as a result of what craft of blowdown pump treatment causes, corrode and the reason such as chemical dip corrode, cause the generation inside pump flow path empty or interstitial, produce when current touch a nest and cause energy loss. Irrigation works loss of efficiency.
2. because of current erode, wall of water pump flow path and impeller cross surface to become coarse and rough, the frictional resistance coefficient of the flow path inside water pump increases, be in plus water the velocity of flow inside pump is very large, of pressure head loss is added. Hydraulic loss of efficiency.
Because 3. is cast add the account such as medicaments or water quality, make inside pump case serious scale or corrode. The scale inside pump case is serious can make pump case wall large increase 2mm left and right sides, and water pump wall forms dirty tumour, it is quantity of contractible, pump water reduces pump housing volume, and flow path is coarse, head loss is added. Cubage efficiency and irrigation works efficiency Zuo .
Loss of machinery of estrangement of 4. volume cause. Because pump uses time to grow, of obstruction of estrangement of leakage of mechanical wear generation is big, make cubage efficiency and mechanical loss of efficiency. Above reason, make water pump function becomes poor. 2~5% of moving loss of efficiency, serious can make water pump loss of efficiency 10% above.
The cavitation erosion of 5. impeller surface, because blade carries negative pressure of the generation when surface moves on the back, when pressure Pk<Pva, after producing steam acupuncture point and beehive appearance, action is corroded to fall in electrochemistry, make pump leaf cavitation.
Thank you very much to Shandong Hairui Zhonglian Pump Industry Co. , ltd. The visit of official website! Above is aboutBlowdown pumpThe introduction that why can efficiency reduce slowly, 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 returns production to suck pump oneself, welcome you at any time seek advice.
