Hydraulic oil carries out thermometric and carries out temperature switch action to motor in system.
Further, the outer surface of motor and hydraulic pump is provided with radiating fin.In the design of fluid pressure drive device
Cheng Zhong, key issue are the set locations of motor.Hydraulic pump can be placed into fuel tank internal, and the motor of domestic production can only be put
Into indoor or water.Hydraulic power unit and outer surface of motor in the present invention are oil-immersed type, are arranged on the fuel tank full of hydraulic oil
It is interior.The radiating fin of device outer surface, can heat effectively caused by the operation of loss equipment, ensure the stabilization of its long-term work
Property.
For a kind of Jing Yin fluid pressure drive device provided in the present invention, there is simple in construction, easy to operate, stability height
The features such as.The shortcomings that overcoming conventional hydraulic drive device, substantially increase the operational efficiency of device, safe for operation, reliability
It is high.
Except providing a kind of Jing Yin fluid pressure drive device, the present embodiment additionally provides carries out Jing Yin hydraulic pressure using described device
The method of driving.Comprise the following steps：
(1) motor is connected with hydraulic pump, is placed on fuel tank internal；
