Shandong Hairui Zhonglian Pump Industry Co. , ltd. The conduit pump that is a major produces manufacturer. When type selecting of client conduit pump, manufacturer of my company water pump can provide the before-sales service such as price of pump of conduit pump model, conduit, 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 the knowledge that fights cavitation erosion function about how raising conduit pump:
Raise conduit pump to fight cavitation erosion function to conduce to the service life that prolongs conduit pump, what measure can raise conduit pump to fight cavitation erosion function so? Conduit pump expert puts forward to suggested at 2 o’clock: (One) improve the plant that enter fluid surplus of significant cavitation erosion; (2) raise conduit pump itself to fight cavitation erosion function.
One, improve the plant that enter fluid the measure of surplus of significant cavitation erosion:
Device instead is sucked to flow backward on 1. general device.
2. reduces the installation height of pump of suction device conduit.
3. increases the pressure of face of the fluid in canister of fluid of the lay aside before conduit pump, in order to raise surplus of significant cavitation erosion.
4. is reducedConduit pumpBefore the loss of going from place to place on pipeline. If asking limits shortens as far as possible pipeline, reduce the velocity of flow in pipeline, reduce bent housing and valve, increase valve to leave as far as possible degree etc.
2, the measure that raises conduit pump itself to fight cavitation erosion function:
Inducer of the buy before 1. is used, make current does work ahead of schedule in advanced buy inducer, in order to increase current pressure.
2. is used double suck impeller, let current from impeller two side enter impeller at the same time, import sectional increase one times, entrance velocity of flow can reduce one times.
3. uses the data that fights cavitation erosion. Practice makes clear, the intensity of material, hardness, tenacity is taller, chemical stability is better, the performance that fights cavitation erosion is stronger.
4. design operating mode is used largish developing part, import part in order to increase blade, reduce what blade entrance is in to bend, reduce blade block, in order to increase entrance acreage; Improve the working condition below large flow, in order to reduce loss of going from place to place. Dan Zhengchong angle shoulds not be too great, affect efficiency otherwise.
5. improves the air suction opening of conduit pump to be designed to the structure near impeller. Had increased to shed an area; Increase impeller cover board to import paragraph curvature radius, reduce current to be quickened quickly with step-down; Reduce the thickness that blade imports appropriately, import blade Xiu Yuan, make its are close to streamline form, also can reduce those who circle ministry of titles drifting a leaf to quicken with step-down; Improve impeller and appearance of blade import share bright and clean degree in order to reduce obstruction loss; blade import side is imported to impeller outspread, make current is accepted ahead of schedule do work, increase pressure.
Above measure can be mixed according to the type selecting of conduit pump, select material the condition such as the use spot of conduit pump, undertake integration analysis, try to apply appropriately.
Thank you very much to Shandong Hairui Zhonglian Pump Industry Co. , ltd. The visit of official website! Above is the introduction that fights cavitation erosion function about how raising conduit 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 returns production to suck pump oneself, welcome you at any time seek advice.
