Abstract

The invention discloses a hydraulic cylinder controlled swash plate type plunger hydraulic transformer and relates to a swash plate type piston hydraulic transformer, aiming at solving the problems that the manually controlled hydraulic transformer can not control the flow and the pressure accurately and the electricity-controlled quantitative type hydraulic transformer can not realize displacement regulation. A rear port plate is fixedly connected with a front port plate; the rear port plate is processed with a gear; a rack is arranged inside a hydraulic cylinder and is fixedly connected with a piston; the rack is meshed with the teeth on the rear port plate; a main axis penetrates the transition block of an oil circuit and then is fixedly arranged in the rear port plate; a high-pressureoil hole on the transition block of the oil circuit is communicated with a high pressure oil circuit on the front port plate by a high-pressure oil duct on the main axis and a high-pressure channel on the rear port plate; a load oil hole on the transition block of the oil circuit is communicated with a load oil circuit on the front port plate by a load channel on the rear port plate; and the oil hole of an oil sump tank on the transition block of the oil circuit is communicated with the oil circuit of the oil sump tank on the front port plate by the channel of the oil sump tank on the rear port plate. The hydraulic transformer can accurately control the flow and pressure and achieve displacement regulation.

Description

technical field [0001] The invention relates to a swash plate type plunger hydraulic transformer, which belongs to the technical field of hydraulic components. Background technique [0002] The hydraulic constant pressure network secondary regulation technology developed in recent years has improved the flexibility and efficiency of the hydraulic system. The principle of secondary regulation has many advantages. However, when driving a linear load, the traditional method is to achieve throttling control. Since there is a large pressure difference in throttling control, this control method brings a large energy loss. How to transmit the energy of the constant voltage network with variable pressure without energy loss like a power transformer or a mechanical gear transmission, this is the technical background of the hydraulic transformer. [0003] The traditional hydraulic transformer directly connects the hydraulic motor and the hydraulic pump coaxially. By adjusting the dis...
