Description
Technical field：
The invention belongs to pump type seal technical field, it is related to a kind of preparation method of liquid pump cyclic sealing gasket, especially
It is a kind of with multi-sealed cable architecture, liquid pump is reduced gas-liquid leakage, effectively improve the annular seal of liquid pump lift value
The preparation technology of pad.
Background technology：
Liquid pump is the device for the energy for the mechanical energy of prime mover being converted to liquid；Liquid pump is before activation, first in pump
The liquid conveyed is filled in shell, after startup, prime mover rotarily drives liquid pump rotation, and liquid pump impeller is revolved at a high speed
Turn, while impeller drives interlobate liquid to rotate, liquid is thrown to impeller outer edge from impeller central under the influence of centrifugal force
And energy is obtained, and to leave impeller outer edge at a high speed into volute pump case, liquid flows into discharge line with higher pressure, defeated
Deliver to the place of needs；When liquid flows to outer rim by impeller central, certain vacuum is formd in impeller central, due to storage tank liquid
Pressure above face is more than the pressure of liquid pump porch, and liquid is just by continuously press-in impeller；Therefore, if liquid pump porch
Connecting portion have gas-liquid leakage phenomenon, then the reduction of vacuum at pump intake, reduce that liquid pump external and internal pressure is poor, shortening is raised
Journey (lift is the increment to energy at pump housing outlet at pump housing import of the Unit Weight liquid pumped of pump), as a result liquid is just
The place of needs can not be transported to.In the prior art, end face and liquid input tube road end face at the casing inlet of liquid pump
Between be directly connected to fix by bolt, contact of the face with face make sealing effectiveness not good；Therefore, a kind of liquid pump ring-type is sought
The preparation method of sealing gasket, prepares a kind of cyclic sealing gasket with multi-sealed cable architecture, and the liquid installed in liquid pump enters
Between mouth and liquid input tube road, ensure high between sealing gasket and liquid input tube road between liquid inlet and sealing gasket respectively
Effect is tightly connected, and reduces gas-liquid leakage, improves pump housing work lift and operating efficiency, and the preparation method of sealing gasket is simple, is easy to
Popularization.
The content of the invention：
The goal of the invention of the present invention is the shortcoming for overcoming prior art to exist, and seeks to design a kind of liquid pump ring-type close
The preparation method of packing, to solve poor sealing after being connected between the casing inlet of existing liquid pump and liquid input tube road,
Gas-liquid leakage causes lift to shorten, the problem of useful work reduces, effectively the sealing of enhancing casing inlet junction, improves output
Power, increases the lift value of liquid pump.
