Abstract

The invention discloses a double-acting plunger pump comprising a left hydraulic pump and a right hydraulic pump. The double-acting plunger pump is characterized in that the hydraulic pumps comprise a left hydraulic mechanism and a right hydraulic mechanism which are symmetrically arranged; a driving gear is arranged between the left hydraulic mechanism and the right hydraulic mechanism and is meshed with a driven gear; the actuation end of the driving gear is connected with a servo motor; the left hydraulic mechanism and the right hydraulic mechanism are connected with the driving gear and the driven gear by a crank connecting rod transmission mechanism; the oil outlets of the left hydraulic mechanism and the right hydraulic mechanism are respectively connected with an actuating mechanism by a check valve; and the oil return openings of the left hydraulic mechanism and the right hydraulic mechanism are respectively connected with an oil tank by the check valve. In the double-acting plunger pump, output flow can be subjected to constant-flow output, and the double-acting plunger pump has smaller friction and vibration, small noise pollution and a simple structure.

Description

technical field

[0001] The invention relates to a hydraulic component, in particular to a double-acting plunger pump. Background technique

[0002] At present, in the hydraulic pump, the plunger pump has been widely used for its simple working principle. The principle is: when the driving force drives the plunger to reciprocate in the plunger hole of the cylinder, the plunger and the cylinder are composed The volume of the closed working chamber changes, so as to realize the process of oil suction and discharge. The plunger pump has the advantages of high rated pressure, compact structure, high efficiency and convenient flow adjustment.

[0003] The plunger pump can be divided into radial type and axial type according to the different arrangements of the plunger in the cylinder. The plungers of the radial piston pump are installed radially in the cylinder body, and the cylinder body is driven by the prime mover to rotate, so the cylinder body is generally called the rotor. ...
