Problems solved by technology

[0003] In order to overcome the current field of mechanical equipment hydraulic control systems, especially the hydraulic station in the aspect of hydraulic transmission and reversing control, the hydraulic station is not integrated, and a variety of hydraulic control parts, electronic and electric controls, etc. are required to be connected to complete the hydraulic transmission and reversing, resulting in uneven hydraulic operations. Stability, not suitable for low temperature operation, poor maintenance and other defects, the invention provides a reversing oil pump station device, the reversing oil pump station device adopts a reversing valve body, an oil pump body and a low-voltage motor in one design, The power supply uses low voltage to control the start or stop of the motor with the zero line, which realizes the one-time operation of the control handle to start the motor and complete the hydraulic transmission and reversing, which is more suitable for low temperature operation

Abstract

The invention discloses a reversing oil pump station device. An oil pump body and a reversing valve body are manufactured or combined as a whole to be connected with a motor; a reversing lever and the reversing valve body are assembled together; a control handle is provided with handle contacts which correspond to an upper contact and a lower contact; during operation, the control handle is pressed, hydraulic oil enters an oil cylinder through a pipe B, and the oil cylinder is extended; when hydraulic transmission reversing is required, the control handle is lifted, the hydraulic oil enters the oil cylinder through a pipe A, and the oil cylinder is contracted; when the control handle is in the middle position, the handle contacts are not in contact with the upper contact and the lower contact, and the reversing oil pump station device is in a service-unavailable state.

Description
