Shandong Hairui Zhonglian Pump Industry Co. , ltd. The blowdown pump that is a major produces manufacturer. When type selecting of client blowdown pump, manufacturer of my company water pump can provide the before-sales service such as price of pump of blowdown pump model, blowdown, 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 blowdown pump lift exorbitant the knowledge that uses an influence to pump:
Above all must we know why can the client choose blowdown pump lift exorbitant?
Reason one, too one-sided to the understanding of lift, the fault regards the length of conduit giving water as lift, bring about blowdown pump lift to be more than real need.
Reason 2, because the user is right,the computation of blowdown pump lift does not have a standard, think anthology a bit bigger always be better, stem from conservative psychology, be in after deciding lift, still add a few meters more, concern is smoked do not sail upstream the anxiety that coming is an user all the time.
Reason 3, the operating mode that the blowdown pump that uses in soar Cheng operating mode so changes low lift will use, can save brushstroke fund so, improper nevertheless.
Reason 4, the lift discretion of blowdown pump and rotate speed have immediate concern, rotate speed is higher, lift is taller, the groovy rotate speed of water pump has 760 to turn, 980 turn, 1450 turn, 2900 turn, if electric machinery extremely several misfit, cause water pump rotate speed exorbitant, also can cause lift exorbitant.
We were told about aboveBlowdown pumpThe reason with exorbitant lift, appear what can such circumstances cause to affect?
When blowdown pump lift when the choice is too tall, water pump runs, carry water the inferior height of real need, redundant pressure can produce changeover, make the rotate speed of blowdown pump increases, the flow that can bring about water pump so is too large, the power that consume increases, the electric current of electric machinery greatens, too big when cause overload to protect effective and automatic tripping operation.
To such circumstance, how should be we solved? The method has 4 kinds:
One, the valve that through involving small conduit will control flow, achieve the goal that controls electric current thereby.
2, ravel blowdown pump, the external diameter cut impeller is small, reduce discharge and lift, nevertheless cut value has a limit, need attention, if be cut too much,abandoned.
3, change water pump, choose the blowdown pump of the lift of adjacent and real need. (real work lift cannot under pump of rated lift 80% )
4, timing of electric machinery of use frequency conversion, will control the on any account of the size of discharge and lift through changing rotate speed, the situation that avoids to exceed electric current happens.
Summary: Blowdown pump has normally relatively actor work area, one allows working area and blame work area. Advanced influence of life of equipment of oppose of two interval labour is not very big, if be in moving impact of blame work area is bigger, because the design of blowdown pump is designed according to rated operating mode, once deviate operating mode can cause radial load, cavitation surplus produces change, cause oscillatory, calorific reach hair of frequency of sealed bearing breakdown to wait. Pump should contrast to produce the pump function curve that manufacturer gives out when choosing pump, must choose to be inside the working interval of function curve, cannot design curvilinear terminal more than namely.
Thank you very much to Shandong Hairui Zhonglian Pump Industry Co. , ltd. The visit of official website! Above is about blowdown pump lift exorbitant the introduction that uses an influence to pump, 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 the pump below fluid, welcome you at any time seek advice.
