Problems solved by technology

[0003] The method used to increase the strength of the high-pressure steel sleeve is similar to the principle of self-tightening of the gun barrel. At present, the self-tightening of the high-pressure steel sleeve is mostly used in the form of hydraulic self-tightening and mechanical self-tightening, but the hydraulic self-tightening technology is expensive and needs to be adjusted. The steel sleeve is sealed, and it is difficult to seal when the self-tightening pressure is high, so it is not suitable to adopt the hydraulic self-tightening method, and the mechanical self-tightening device has poor universality, which is not conducive to wide use

Abstract

The invention discloses a steel sleeve rolling self-tightening device for a high-pressure plunger pump. The steel sleeve rolling self-tightening device comprises a mounting base, a first fixing seat,a second fixing seat, a roller frame, a first driving device, a first driving mechanism, a second driving device, a second driving mechanism, a steel sleeve assembly and a roller assembly, wherein thefirst fixing seat and the second fixing seat are mounted on the mounting base; the roller frame is arranged outside the first fixing seat and the second fixing seat in a sleeving mode and slidably connected with the first fixing seat and the second fixing seat; the first driving device is mounted on the mounting base and connected with the first driving mechanism; the second driving device is mounted on the mounting base and connected with the second driving mechanism; the steel sleeve assembly is rotatably connected to the first fixing seat and the second fixing seat; and the roller assemblycan penetrate through the steel sleeve assembly and is rotatably connected to the roller frame. The steel sleeve rolling self-tightening device for the high-pressure plunger pump is low in cost and has universal applicability.

Description

technical field [0001] The invention relates to the technical field of a steel sleeve self-tightening device for a high-pressure plunger pump, in particular to a steel sleeve rolling self-tightening device for a high-pressure plunger pump. Background technique [0002] Since the high-pressure steel sleeve in the high-pressure plunger pump needs to bear the action of reciprocating high and low pressure stress at all times, the strength and service life of the high-pressure steel sleeve are important factors to ensure the quality of the high-pressure plunger pump. [0003] The method used to increase the strength of the high-pressure steel sleeve is similar to the principle of self-tightening of the gun barrel. At present, the self-tightening of the high-pressure steel sleeve is mostly used in the form of hydraulic self-tightening and mechanical self-tightening, but the hydraulic self-tightening technology is expensive and needs to be adjusted. The steel sleeve is sealed, and ...
