Annular sealing gasket for liquid pump

Abstract

The invention belongs to the technical field of pump sealing, and particularly relates to an annular sealing gasket for a liquid pump. The main structure comprises a sealing gasket base, a cylinder, a boss, a bolt penetration hole, a first inner ring sealing line, a second inner ring sealing line, a first outer ring sealing line, a second outer ring sealing line, an outer circle and an inner circle, wherein the cylinder is arranged on the periphery of the inner circle of the sealing gasket base; the boss is arranged on the cylinder; the bolt penetration hole is formed in the sealing gasket base; the first inner ring sealing line, the second inner ring sealing line, the first outer ring sealing line and the second outer ring sealing line are arranged on the sealing gasket base; the air tightness at the inlet connection position of the liquid pump is increased; and sealing line structures are arranged on the upper face and the lower face of a sealing gasket disk, so that close contact of an impeller and a water inlet pipe during connection is achieved, gas-liquid leakage is reduced, the lift value is increased and the sealing effect is improved effectively. The structure of the annular sealing gasket is simple and ingenious; materials are used scientifically and reasonably; the preparation cost is low; the use effect and the energy-saving effect are excellent; mass production is facilitated; and the application environment is friendly.

Description

Technical field: [0001] The invention belongs to the technical field of pump sealing, and relates to an annular sealing gasket for a liquid pump, in particular to an annular sealing gasket with multiple sealing line structures, which can reduce gas-liquid leakage and effectively increase the head value. Background technique: [0002] The liquid pump is a device that converts the mechanical energy of the prime mover into the energy of liquid flow; before the liquid pump is started, the pump casing is filled with the liquid to be transported. After the start, the prime mover rotates to drive the liquid pump shaft to rotate, and the liquid pump shaft Drive the impeller to rotate at high speed, and at the same time, the impeller drives the liquid between the blades to rotate. Under the action of centrifugal force, the liquid is thrown from the center of the impeller to the outer edge of the impeller and obtains energy, and leaves the outer edge of the impeller at high speed and e...
