Abstract

The invention discloses a manufacturing process of a plunger pump shell, the plunger pump shell and a plunger pump. The manufacturing process of the plunger pump shell comprises the following steps that thermal refining is conducted on a medium carbon steel shell base body (100); the quenched and tempered medium carbon steel shell base body (100) is machined, an inner cavity (110) of the medium carbon steel shell base body (100) is machined to the surfacing size, and the surfacing size is larger than the preset size of the inner cavity (110); surfacing a duplex stainless steel layer (200) on the side wall of the inner cavity (110); and processing the inner cavity (110) to the preset size. According to the scheme, the problem that the safety and reliability of the plunger pump are poor can be solved.

Description

technical field [0001] The invention relates to the technical field of oil and gas field pumping equipment, in particular to a manufacturing process of a plunger pump casing, a plunger pump casing and a plunger pump. Background technique [0002] The plunger pump is the main equipment for high-pressure pumping liquid medium in the production process of oil and gas fields. The plunger pump includes power end housing, liquid end housing, crankshaft, tappet and plunger. The crankshaft is located in the power end housing. One end of the tappet penetrates into the power end housing and is connected with the crankshaft. The other end of the power end is located outside the housing and is connected to the plunger. The plunger part is located within the liquid end housing. The crankshaft drives the tappet to move back and forth, so that the tappet drives the plunger to move back and forth to realize the suction and discharge of the plunger pump. [0003] The liquid end shell of t...
