Machining process for connecting rod of high-pressure plunger pump

Abstract

The invention discloses a machining process for a connecting rod of a high-pressure plunger pump. The machining process for the connecting rod of the high-pressure plunger pump specifically comprises the following machining steps that S1, a connecting rod blank is obtained, specifically, the blank is made according to the requirement, the size and the material of the blank meet the machining requirement, the blank is inspected to be prevented from having obvious defects, and an initially inspected blank is obtained; S2, the blank is measured and roughly machined; S3, dynamic balance detection is carried out on the roughly machined object; S4, reinforcement treatment is carried out on the detected object; S5, finish machining is carried out on the object obtained after reinforcement treatment; S6, quenching treatment is conducted on the object obtained after finish machining; and S7, the finished product is packaged, specifically, the qualified product quenched in the step S6 is packaged. Compared with an existing machining process for the connecting rod of the high-pressure plunger pump, the operation method is simple, it is guaranteed that the machined connecting rod is high in external strength and good in hole internal flexibility, the service life is prolonged, the machining precision of the connecting rod is guaranteed, installation is accurate in the using process, and abrasion is reduced.

Description

technical field [0001] The invention relates to a process for processing a connecting rod of a high-pressure plunger pump, which belongs to the technical field of material processing. Background technique [0002] The operating pressure of the high-pressure plunger pump should generally be between 10MPa and 100MPa. It belongs to the positive displacement pump, which achieves the purpose of conveying liquid by means of the periodic change of the volume in the working chamber; the mechanical energy of the prime mover is directly converted into the pressure energy of the conveying liquid through the pump; the capacity of the pump only depends on the volume change value of the working chamber and its The number of changes per unit time has nothing to do with the discharge pressure in theory. The reciprocating pump uses the reciprocating motion of the piston in the working chamber of the hydraulic cylinder (or the periodic elastic deformation of flexible elements such as diaphra...
