Belong to industrial centrifugal pump technical field.
Background technology
Before generally industrial centrifugal pump opens pump will in pump chamber injected media, be commonly called as pump priming, otherwise centrifugal pump can not normal startup optimization.
One of tradition pump priming method is to build head-tank, and pump is placed in lower, it is achieved pump chamber is just pressing water, this method not only construction costs
Height, the maintenance cost in pond is the highest.Another kind of common pump priming method is to arrange bottom valve at suction line lowest part, first to pump chamber
Opening pump, this method troublesome poeration after inside filling medium again, fault rate is high, bottom valve maintenance also difficulty.
For just opening pump problem after solving centrifugal pump elder generation pump priming, people begin attempt to the sky using vacuum pump to extract in centrifugal pump pump chamber
Gas, is pressed into pump intake pipeline by atmospheric pressure medium, it is achieved tank pump.Vacuum pump can solve centrifugal pump pump priming problem, but commonly
There is following shortcoming in vacuum pump: 1, equipment manufacturing cost is high, floor space is big；2, operation complexity, repair and maintenance workload is big；3、

Empty device, by pump main shaft by clutch, drive mechanism, drives and inhales vacuum auxiliary device.Inhale vacuum equipment and pass through suction nozzle
Connecting with pump intake pipeline, when opening pump, clutch closes, pump main shaft by actuator drives inhale vacuum equipment work, extract into
Air in mouthful pipeline also forms negative pressure, and medium under atmospheric pressure, is entered suction line, pump chamber by pond.Pump startup
After operation, clutch departs from, and inhales vacuum equipment and quits work.The shortcoming of this device is: 1, structure is complicated, and fault rate is high.
To arrange suction vacuum equipment on pump, actuating device, arrangement of clutch could realize suction vacuum function, and the number of parts increase of pump is several
Times.When 2, playing pump, pump chamber does not has medium, is unfavorable for that pump seal uses.If do not taked auxiliary lubricating device, sealing member such as machinery
Seal, packing seal is in dry grinding state；If taking auxiliary lubricating device, then improve equipment manufacturing cost, adding equipment complicated
Degree and fault rate.3, the vibrations inhaling vacuum equipment are big, have a strong impact on pump main shaft, main shaft bearing, pump torr, mechanical seal or fill out
The service life of material.4, noise is big, pollutes environment.5, maintenance difficulty.No matter maintenance pump or vacuum aided mechanism, will
All disassembling centrifugal pump, inhale vacuum system, the parts and components related to is many, complex operation, and labor intensity is big.
