Abstract

The invention discloses an integrated hydraulic transformer, relates to a hydraulic transformer, and aims to solve the problems that throttling losses exist in an existing transformer, and the transformer is small in regulating ratio range and large in noise in the operating process. A left end cover, a shell and a right end cover are sequentially connected from left to right, an outer annular swash plate is rotatably arranged in the left end cover, an inner annular swash plate is arranged on the outer annular swash plate, an outer swash plate adjusting rod penetrates through the left end cover and is connected with the outer annular swash plate, an inner swash plate adjusting rod sequentially penetrates through the left end cover and the outer annular swash plate and then is connected with the inner annular swash plate, a cylinder block and a thrust plate are sequentially arranged in a sealing inner cavity from left to right, a needle bearing is externally arranged on the cylinder block, one ends of a plurality of plungers are matched with plunger holes in the cylinder block, the other ends of the plungers are hinged to piston shoes, and the piston shoes are restrained on the swash plates through inner baffle rings and outer baffle rings. The integrated hydraulic transformer is used for hydraulic transformation.

Description

technical field [0001] The invention relates to a hydraulic component, in particular to an integrated hydraulic transformer. Background technique [0002] The secondary regulation technology of constant pressure network developed in recent years has improved the flexibility and efficiency of the hydraulic system. However, although the principle of secondary regulation has many advantages, its application in the field of hydraulic pressure has been limited. In terms of driving the rotating load, the driving of the rotating load can be realized by adjusting the adjusting mechanism of the variable hydraulic motor. The traditional method of driving linear loads with different load pressure requirements is through a throttling control method. Since the throttling control method has a large pressure difference, this control method brings a large energy loss. How to transmit the energy of the constant voltage network with a certain pressure without energy loss like a power transf...
