Abstract

The invention relates to a processing technology for a plunger and barrel assembly. The plunger and barrel assembly comprises a plunger and a barrel. The plunger and the barrel are processed through processing technologies for the plunger and the barrel respectively, and then the plunger and the barrel are assembled together, so that the plunger and barrel assembly is formed. According to the processing technology for the plunger and barrel assembly, the processing is convenient; the technology is simplified; the processing flow is reduced; and on the premise that the product quality is guaranteed, the production cost is reduced, and the processing accuracy is improved.

Description

technical field [0001] The invention relates to the technical field of plunger pair processing technology for oil pump parts in diesel engines, in particular to a PW2000 plunger pair processing technology. Background technique [0002] The plunger couple is the fuel injection plunger of the high pressure oil pump of the diesel engine. Due to the precise fit of the plunger couple and the high-speed movement of the plunger, the fuel can be pressurized. In the prior art, the process route for the processing of the plunger pair is cumbersome and long, and dust is easily generated during the process, and the dust in the workplace is harmful to employees. Contents of the invention [0003] Aiming at the shortcomings in the above-mentioned existing production technology, the applicant provides a plunger pair processing technology, which simplifies the processing technology, reduces the processing flow, reduces the production cost and improves the product quality under the premis...
