Description

Technical Field

[0002] A reciprocating pump is a positive-displacement pump that relies on the reciprocating motion of a piston, plunger, or diaphragm in a pump cylinder to alternately increase and decrease the working volume in the cylinder to transport or pressurize a liquid. Among them, a high-pressure reciprocating pump is one of the common reciprocating pumps. When disassembling and repairing a high-pressure reciprocating pump, a disassembly tool is required.

[0003] Referring to the patent document with publication number CN218875286U, a disassembly tool for a high-pressure reciprocating pump is disclosed. The high-pressure reciprocating pump includes a crank-link mechanism and a stuffing box with a central through hole arranged at an interval from the crank-link mechanism. Through the above technical solution, the crank-link mechanism in the high-pressure reciprocating pump is reasonably utilized, the operation is convenient and safe, the disassembly is easy, and the working efficiency is greatly improved.

[0004] Although the above solution can disassemble the crank-link during use, there are still some deficiencies in the process of use. For example, when it is difficult to disassemble the piston assembly, it is necessary to pull the piston assembly upward, and then manually support the piston assembly so that another worker can disassemble the piston rod. However, during the disassembly of the piston rod, the worker needs to support the piston rod for a long time, which not only increases the labor intensity of the worker, but also easily causes the piston rod to shake during the operation, affecting the disassembly efficiency of the worker. Therefore, a disassembly tool for a high-pressure reciprocating pump is proposed. Summary of the Utility Model
