Problems solved by technology

At present, there is no experience in the manufacture of similar components in the combination of steel matrix and copper alloy in the combination of cylindrical surface and hole. At present, the domestic solution to the composite problem of the plunger hole (cylindrical hole) of the hydraulic plunger pump cylinder, The method of pouring or inlaying copper sleeves is usually used. The pouring method is to melt the copper and manually pour the copper liquid on

Example Embodiment

[0012] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Such as figure 1 As shown, a composite copper alloy plunger pump cylinder body is processed from a blank 1 with a spherical concave surface 3 in the center of the top of the blank 1 and a circle of columns is arranged inside the blank 1 In the cylinder hole 3, a copper sleeve 5 is arranged in the cylinder hole 2, and the copper sleeve 5 is sleeved on the core rod 4, and the top end of the copper sleeve 5 is lower than the top end of the core rod 4. A through hole is opened in the center of the core rod 4, a sealing plate 6 is installed on the lower end surface of the blank 1, and the sealing plate 6 is provided with an air hole communicating with the through hole on the core rod 4.

[0013] During production, the first step is to clean the cast surface of the blank 1 and then apply the metal activator to the cast surface of the steel substrate f...

Abstract

The invention discloses a processing method of a composite copper alloy plunger pump cylinder body. The processing method is characterized in that a copper alloy bush (5) and a core rod (4) are arranged in a cylinder body hole; and meanwhile, another kind of copper alloy material is placed in a spherical concave surface (3) at the top center of a cylinder body blank (1), and a method of heating and cooling is utilized, so that different copper alloys can be compounded on two different working faces of the plunger pump cylinder body, and further the performance of a plunger pump is improved and the service life of the plunger pump is prolonged.

Description

technical field [0001] The invention relates to the field of plunger pump manufacture, in particular to a processing method for a composite copper alloy plunger pump cylinder. Background technique [0002] In order to solve the problem of friction pair matching between the cylinder body and the plunger, oil distribution plate and other parts during use, the cylinder body of the existing hydraulic plunger pump is a composite component composed of a steel matrix and a copper alloy. The composite surface includes Planar, curved, cylindrical, and holes. At present, there is no experience in the manufacture of similar components in the combination of steel matrix and copper alloy in the combination of cylindrical surface and hole. At present, the domestic solution to the composite problem of the plunger hole (cylindrical hole) of the hydraulic plunger pump cylinder, The method of pouring or inlaying copper sleeves is usually used. The pouring method is to melt the copper and man...
