Problems solved by technology

This self-flushing structure uses its own medium to flush the filler 5a. Due to the characteristics of particles and viscosity in the medium of the pump body 1a, the pump shaft 4a and the filler 5a wear relatively quickly, which is easy to cause wear on the pump shaft 4a and reduce the pump life

Abstract

The invention relates to a pump cover of a filler pump. The pump cover comprises a pump cover body. A shaft hole and a filler cavity communicated with the shaft hole are formed in the middle of the pump cover body. The pump cover of the filler pump is characterized in that an outer washing channel is formed in the pump cover body, one end of the outer washing channel is communicated with the filler cavity, and the other end of the outer washing channel is communicated with the outside. A pump cover bolt hole used for fixing the pump cover body is formed in the edge of the pump cover body. The outer circle of the filler cavity is provided with a gland bolt hole used for installing a filler gland. According to the pump cover of the filler pump, an external washing medium is used for washing filler, abrasion between a pump shaft and the filler is greatly reduced, the service life of a water pump is prolonged, and the pump cover is simple in structure and cannot increase production and equipment cost.

Description

technical field [0001] The invention relates to a pump cover, in particular to a pump cover of a stuffing pump, and belongs to the technical field of mechanical structures. Background technique [0002] The structure of packing pump in the prior art is generally as follows figure 1 As shown, it includes a pump body 1a, an impeller 2a, a pump cover 3a and a pump shaft 4a, the pump shaft 4a passes through the pump cover 3a and is connected to the impeller 2a, and the stuffing cavity between the pump cover 3a and the pump shaft 4a is filled with filler 5a. At present, the pump cover of the packing pump generally adopts a self-flushing structure, that is, a self-flushing pipeline 6a is provided on the pump cover 3a, and one end of the self-flushing pipeline 6a communicates with the inner cavity of the pump body 1a, and the other end communicates with the packing cavity, as figure 2 shown. This self-flushing structure uses its own medium to flush the filler 5a. Due to the char...
