What is the loss lift of sumbersible pump pipeline?

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 what the knowledge that is lift of loss of sumbersible pump pipeline:

Everybody knows, conduit is content of a kind of solid, water is the material of easy flow, if the water inside conduit is of flow, sure have heat energy of translate into of one part energy and eliminate, lost one share namely hydraulic (or call lift) , this is the report of external object, it is the inevitable rule that current moves. Normally, the phenomenon that we transform this kind of energy, say for energy loss (or call lift of hydraulic loss, loss) . It is computational unit with rice.
Loss lift, it is the block sluggish action with harsh tube wall, 2 it is current spreads the opposite campaign between the layer each, 3 it is the eddy that local and sharp change forms the current inside pipe fitting. Pipeline (net) hydraulic loss by ministry of edge Cheng standoff two parts are comprised. On the project, the amount that we must want computation to know it how many, ability chooses sumbersible pump correctly.
Loss of pipeline edge Cheng is the attrition obstruction that happens on the whole technological process of current, it and tube wall surface roughness, canal diameter of long, canal, velocity of flow about, according to hydraulics principle, can establish its relation. The edge Cheng that concerns along Cheng loss and tube wall surface roughness coefficient of friction concerns into direct ratio, different tubal capable person its surface roughness is different, cast-iron pipe is coarser, along Cheng plastic pipe of somes of coefficient of friction is big; is compared smooth, edge Cheng somes coefficient of friction is small. Concern into direct ratio with pipe length; With the canal diameter concerns into inverse ratio, that is to say, when flow is constant, tubal diameter small, velocity of flow is rapid, criterion edge Cheng loss is big; Still concern into direct ratio with the square value of velocity of flow.
After decorating plan to decide when pipeline, want to get pipeline loss lift through computational method commonly, decide the rated head of phreatic water pumping station next, ability undertakesSumbersible pumpType selecting. Rough estimation: Loss lift is equivalent to height of practically form pump up water (measure be informed) 30%~50% , small, pipeline weak point takes tubal diameter to be worth greatly; Big, pipeline grows tubal way take small cost.
Thank you very much to Shandong Hairui Zhonglian Pump Industry Co. , ltd. The visit of official website! Above is about what the introduction that is lift of loss of sumbersible pump pipeline, 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.
