Problems solved by technology

At present, when the servo piston is disassembled without damage, the spring must first be compressed by the spring seat, and then the retaining ring and the retaining spring for the hole in the figure can be taken out. The outer sleeve of the piston is used in conjunction with the cylinder on the pump housing. Its surface accuracy and smoothness are very high, and the surface cannot be used as a clamping object.

Abstract

The invention relates to a waste hydraulic pump disassembly line comprising a plunger pump disassembly station. The waste hydraulic pump disassembly line is characterized in that the upper stream of the plunger pump disassembly station is connected with a waste oil recovery device, the plunger pump disassembly station is connected with a hydraulic manifold block disassembly station, a servo piston disassembly station and a pump housing disassembly station through a part conveying line, the hydraulic manifold block disassembly station is connected with a valve body disassembly station through the part conveying line, and the valve body disassembly station is connected with a material recovery box through a material recovery conveying line. The waste hydraulic pump disassembly line has the advantages of reasonable layout and high working efficiency.

Description

technical field [0001] This patent belongs to the technical field of recycling of hydraulic pumps, in particular to a dismantling line for waste hydraulic pumps. Background technique [0002] When remanufacturing waste plunger pumps used in the field of construction machinery, it must first be disassembled without damage. With the increase in the number of various types of construction machinery in our country, more and more plunger pumps for waste construction machinery need to be remanufactured. This requires the establishment of a reasonable dismantling line in order to carry out efficient and large-scale dismantling, and As a relatively precise hydraulic part, the plunger pump can be disassembled efficiently and non-destructively only by following a reasonable disassembly process, using reasonable disassembly tooling, fixtures and correct disassembly methods. At present, there is not a plunger pump dismantling line that is arranged according to a reasonable dismantling ...
