[0002] A three-plunger high-pressure pump is a common pump used in high-pressure hydraulic transmission systems. The three-plunger high-pressure pump uses three plungers as working elements, compresses the liquid through reciprocating motion and outputs high-pressure fluid. When the driving mechanism drives the plungers to reciprocate, due to the sealing between the plungers and the pump chamber, the liquid in the pump chamber will be compressed and forced to enter the output pipeline through the valve. As the plungers move, the liquid will be continuously compressed and output to form high-pressure fluid. In this process, the pump flows through the high-pressure seamless steel pipe at a fixed displacement and finally enters outlet devices such as nozzles to realize the application of high-pressure fluid.

[0003] Due to wear caused by long-term use, it is necessary to maintain the guide sleeve of the three-plunger high-pressure pump. Disassembly is a process that requires careful operation during maintenance. Since the structures of three-plunger high-pressure pumps of different models and brands may be different, the sizes of the guide sleeves are not fixed. If the disassembly tools are relatively single, the size range of clamping the guide sleeve cannot be freely controlled, resulting in poor adaptability and the need to frequently replace the disassembly tools, which affects the efficiency.

Through the provision of the threaded sleeve 16, the threaded sleeve 16 can be rotated and displaced along the thread groove 15 on the surface of the mounting tube 1 through the rotating rod 17. When the threaded sleeve 16 abuts against the end face of the positioning tube 6 and is further tightened, the mounting tube 1 will cause the guide sleeve to be gradually pulled out of the mounting hole of the three-plunger high-pressure pump as the threaded sleeve acts until the guide sleeve is completely pulled out.

Since the worm 504 is meshed with the tooth plate 503, when the worm 504 is lifted, it can drive multiple claws 502 to open and close at the same time, clamping and fixing the guide sleeve, and the bolt rod of the fixing bolt 8 extends to the inside of the mounting tube 1 through the fixing hole 7 until it contacts the lifting rod 3, thereby adjusting the position of the lifting rod 3. Fix it and try to avoid loosening of the claw 502. Through the cooperation of the positioning plate 13 and the positioning hole 14, it is convenient to fix the positioning cylinder 6 and the mounting cylinder 1 at the mounting hole port of the three-plunger high-pressure pump guide sleeve. The threaded sleeve 16 can be rotated and displaced along the threaded groove 15 on the surface of the mounting cylinder 1 through the rotating rod 17.
