Problems solved by technology

[0002] The sealing structure of the asphalt delivery pump is commonly used as a mechanical seal, which refers to a seal that prevents fluid leakage by at least a pair of end faces perpendicular to the axis of rotation under the action of fluid pressure and the elastic force of the compensation mechanism and the cooperation of auxiliary seals. The original commonly used spring machinery is easily damaged and cannot be reused. It must be updated every time, which causes a lot of waste, and a good sealing device should have a certain buffering effect

Abstract

The invention discloses a sealing device of an asphalt pump. According to the sealing device, a pump body is arranged, a sleeving connecting block is arranged on the outer side of the pump body; fourfirst limiting blocks are symmetrically arranged on the side walls of the opposite ends of the sleeving connecting blocks separately; first sliding grooves are formed in the side walls of the four first limiting blocks; first sliding blocks are arranged in the four first sliding grooves in a sliding mode; first connecting rods are connected to the side walls of the four first sliding blocks in a rotating mode; every two opposite first connecting rods are connected through a buffering device; each buffering device comprises a first arc-shaped block; two second limiting blocks are symmetricallyarranged on the side wall of each first arc-shaped block; and second sliding grooves are formed in the side walls of the second limiting blocks. The sealing device has the advantages that the structural design is reasonable, the operation is simple, a user can conveniently dismount the sealing device, and in addition, a certain buffering effect can be achieved.

Description

technical field [0001] The invention relates to the technical field of sealing of asphalt delivery pumps, in particular to a sealing device of an asphalt pump. Background technique [0002] The sealing structure of the asphalt delivery pump is commonly used as a mechanical seal, which refers to at least one pair of end faces perpendicular to the axis of rotation, under the action of the fluid pressure and the elastic force of the compensation mechanism, and the cooperation of the auxiliary seal to keep fit and relatively slide to prevent fluid leakage. For the device, the original commonly used spring mechanism is easily damaged and cannot be reused. It must be updated every time, which causes a lot of waste, and a good sealing device should have a certain buffering effect. Contents of the invention [0003] The object of the present invention is to solve the disadvantages of being unable to disassemble and having no buffering effect, and to propose a sealing device for an...
