[0025] The output end of the suction pump 5 is fixedly installed with a connecting pipe 6. An extension hole is provided on the top of the housing 1. The connecting pipe 6 penetrates through the extension hole into the interior of the housing 1. Three nozzles are fixedly installed on the oil guiding pipe 7, which is convenient for pumping the lubricating oil inside the box body 4 into the interior of the oil guiding pipe 7, so as to lubricate the plunger body 2 and reduce the wear of the plunger body 2.
[0026] In addition, the bottom of the connecting pipe 6 is fixedly installed with an oil guiding pipe 7. A controller 8 is fixedly installed on the top of the housing 1. A wear-resistant ring 9 is fixedly installed on the outside of the plunger body 2.
[0027] It should be noted that, for this wear-resistant and fatigue-resistant three-plunger reciprocating process pump, by installing a wear-resistant lubrication component, it is convenient to protect the outside of the plunger body 2 and reduce the damage and erosion of the plunger body 2. And by lubricating the plunger body 2, the wear of the plunger body 2 during operation is reduced, and the service life of the pump body is improved.
[0028] Specifically, for this wear-resistant and fatigue-resistant three-plunger reciprocating process pump, the wear-resistant layer 3 can protect the plunger body 2, improve the corrosion resistance effect of the plunger body 2, and then improve the use effect of the plunger body 2. At the same time, the lubricating oil is put into the box body 4 through the oil inlet pipe, and then the suction pump 5 is started to put the lubricating oil in the box body 4 into the oil guiding pipe 7 through the connecting pipe 6 to lubricate the plunger body 2, reduce the wear of the plunger body 2, improve the service life of the plunger body 2, and improve the use effect of the reciprocating process pump.
[0029] In this embodiment, the limiting component includes a mounting sleeve 11 sleeved on the top of the plunger body 2. Two telescopic springs 12 are fixedly installed inside the placing block 10. A placing groove for placing the mounting sleeve 11 is formed at the top of the placing block 10.

[0034] Specifically, when using this wear-resistant and fatigue-resistant three-plunger reciprocating process pump, the machine shell 1 is disassembled, and then the two L-shaped pull rods 15 are pulled in opposite directions, compressing the two telescopic springs 12, driving the two sliding plates 13 to move, and making the two clamping blocks 14 move synchronously to release the limit on the mounting sleeve 11. Furthermore, it is convenient for the user to take out the plunger body 2 from the inside of the placing block 10 for replacement, repair and other operations.
[0035] The working principle of the above embodiment is as follows:
[0036] (1) For this wear-resistant and fatigue-resistant three-plunger reciprocating process pump, the plunger body 2 can be protected through the wear-resistant layer 3, improving the corrosion resistance effect of the plunger body 2. Furthermore, the use effect of the plunger body 2 is improved. At the same time, lubricating oil is put into the box body 4 through the oil inlet pipe, and then the feeding pump 5 is started to put the lubricating oil in the box body 4 into the oil guide pipe 7 through the connecting pipe 6 to lubricate the plunger body 2, reducing the wear of the plunger body 2, increasing the service life of the plunger body 2, and improving the use effect of the reciprocating process pump.
[0037] (2) When the wear-resistant and fatigue-resistant three-plunger reciprocating process pump is in use, the machine housing 1 is disassembled. Then, the two L-shaped pull rods 15 are pulled in opposite directions, causing the two telescopic springs 12 to be compressed, driving the two sliding plates 13 to move, and enabling the two clamping blocks 14 to move synchronously, releasing the limit on the mounting sleeve 11. Thus, it is convenient for the user to take out the plunger body 2 from the inside of the placing block 10 for operations such as replacement and repair.
