Multifunctional test equipment for centrifugal pump

The utility model relates to a centrifugal pump multi-function tester, which belongs to fluid machinery teaching and study device. The bottom of a high level water tank is connected with a low level water tank through a connecting pipe, after the cavitation adjustment device, the fluid is respectively connected with a pump A4 and a valve A6 through a tee, and the serial bypass is respectively connected with the outlets of the valve A6 and the pump A4 after addedly arranged with a valve 7, the pipeline passing through a pump A5, a valve A8, a flowmeter A9 and another pipeline are joined through the tee and are back flown into a high level water tank 1 through a valve A12.The utility model has the advantages of truly realize the multi-functions integrated: in a system, the performance test, serial test, parallel test, cavitation test, variable speed adjustment test, and automatic water supply control test, etc. can be realized simultaneously; the system adopts the ''open'' type design, and it can be also reassembled or the function can be expansed when necessary.
