Since the balance of multistage centrifugal pump in actual work, indicated the water pressure is the pressure gauge balance multistage pump pump axis to the vertical height and a drain on the surface of the drainage the sum total of all the head loss table indicating the vacuum degree of vacuum is refers to the vertical axis to the suction surface height and the suction pipe road the sum of all losses.
In use process, surface water to the surface vertical height plus on the suction and discharge pipe on the sum total of all kinds of loss must be within the pump head range, the best balance of multistage centrifugal pump operating at the design point condition, when running head in excess of the prescribed scope for a long time, will affect the safety of the pipeline system, using economy, if the head below the prescribed scope, that is to say, the water pump used in large capacity low head case, especially compared to lower pump, shaft power will increase rapidly, lead to motor overload operation, easy to burn out;
Allow the suction of the pump when flow increase height as traffic increases, and make the water pump is easy to produce cavitation, has a great influence on the pump performance, use efficiency is poor, so when using self balancing multistage water pump head are not allowed to running under specified conditions.
Self balancing multistage centrifugal water pump installation height signal structure is as follows: more structure design principle of reference: self balancing multistage pump structure
