Embodiment Construction

[0029] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0030] Such as figure 1 As shown, the present invention provides a novel buckle type split plunger pump swash plate variable adjustment mechanism, including swash plate body 2, snap connection seat 3, hinged connecting rod 4, variable adjustment guide seat 5, variable spring 6 , variable spool 7, valve sleeve 8, spring retainer 9, retaining ring 10 and O-ring 11;

[0031] The swash plate body 2 is installed on the bearing seat of the plunger pump casing 1 through the deep groove ball bearings at the trunnions at both ends;

[0032] The buckle connection seat 3 is fixedly connected with the swash plate body 2; figure 2 , 3 The preferred structure shown is specifically: a plane is set on the peripheral surface of the swash plate body 2 as the installation surface, and a rectangular protrusion is set on the plane; the cross-section o...

Abstract

The invention discloses a novel buckle-type split plunger pump oblique disc variable adjusting mechanism and method. The novel buckle-type split plunger pump oblique disc variable adjusting mechanismcomprises a buckle connecting seat, a hinging connecting rod, a variable adjusting guide seat, a variable spring, a variable valve element, a valve sleeve and a spring blocking piece. The buckle connecting seat is fixedly connected with an oblique disc body; one end of the hinging connecting rod is hinged to the buckle connecting seat, and the other end of the hinging connecting rod is hinged to the variable adjusting guide seat; the valve sleeve is mounted in a plunger pump shell, and the spring blocking piece is mounted at the front end of the valve sleeve; one end of the variable valve element and the variable adjusting guide seat are connected in a threaded mode, and the other end of the variable valve element is mounted in the valve sleeve; the variable valve element is sleeved with the variable spring; and two oil holes are formed in the valve sleeve and communicate with two control oil openings in the plunger pump shell correspondingly. Force bearing in the supporting position of an oblique disc is improved through split-type buckle connection, the pre-compression quantity of the variable spring is changed by adjusting the thread screwing-in mode of the guide seat, angle adjustment of the oblique disc body is achieved through left and right moving of the valve element, and the control performance of an oblique disc type plunger pump can be effectively improved.

Description

technical field [0001] The invention belongs to the technical field of plunger pumps, and in particular relates to a novel buckle type split plunger pump swash plate variable adjustment mechanism and an adjustment method. Background technique [0002] The swash plate axial piston pump is more and more widely used in petrochemical, engineering machinery, aerospace and other fields due to its advantages of high pressure rating, convenient variable control and compact structure. The swash plate is a key component to realize variable control, and the optimal design of its structure is of great significance for improving the performance index of the swash plate axial piston pump. Due to the limited internal space of the plunger pump housing, the traditional one-piece swash plate structure has problems such as complex processing technology, difficult installation and debugging, and severe local structural stress, which greatly affects the performance of the swash plate axial pisto...
