Abstract

The invention relates to a hydraulic transformer with axial flow distribution, belonging to the hydraulic technology field and solving the problems that the existing hydraulic transformer has large volume and complex structure. The hydraulic transformer comprises a cylinder body, a flow distribution plate, a pump shell, a flow distribution shell, a main flow distribution shaft, a bearing, a pin, an end cover and a control mechanism, the flow distribution plate and the main flow distribution shaft are connected by a pin, an electric hydraulic servo mechanism is used for controlling the rotation of the main flow distribution shaft, so as to control the rotating angle of the flow distribution plate and realize change of transformer ratio; a fan-shaped notch is arranged on the flow distribution plate, an oil path of the notch is directly communicated inside the pump shell, and a low-pressure return opening of the same pump is realized to be communicated to an oil tank, so as to realize direct connection of the fan-shaped notch and the oil tank; a waist-shaped groove with the same shape as the flow distribution plate and at the same position as the flow distribution plate is designed on the main flow distribution shaft, so as to realize communication of the oil path. The hydraulic transformer with axial flow distribution is used as the hydraulic pressure transformer.

Description

technical field [0001] The invention relates to a hydraulic transformer with axial flow distribution, which belongs to the technical field of hydraulic pressure. Background technique [0002] With the development of the secondary regulation technology of the hydraulic constant pressure network, the flexibility and efficiency of the hydraulic system have been improved. The secondary regulation technology has many advantages, but when the linear load is driven by throttling control, there is a large Pressure difference, so there will be 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 is the problem to be solved by the hydraulic transformer. [0003] The traditional hydraulic transformer directly connects the hydraulic motor and the hydraulic pump coaxially. By adjusting the displacement of the hydraulic motor, the input pressure is changed to t...
