What is a hydraulic motor, and what is the working principle of the hydraulic motor? Why is he safe, reliable and energy efficient?
Hydraulic travel motor principle: It is a device that uses hydraulic oil to transmit pressure. When the hydraulic oil transmits pressure in a closed container, it is a hydraulic transmission system that follows Pascal's law. The hydraulic transmission system consists of a power mechanism, a control mechanism, an actuator, an auxiliary mechanism, and a working medium. The power mechanism usually uses an oil pump as a power mechanism, generally a positive displacement oil pump. In order to meet the requirements of the speed of the actuator, an oil pump or multiple oil pumps are used. Low-pressure (oil pressure less than 2.5MP) wheel pump; medium pressure (oil pressure less than 6.3MP) with a vane pump high pressure (oil pressure less than 32.0MP) with a plunger pump.
Both the hydraulic machine and the final drive motor are energy conversion devices in the hydraulic system. The difference is that the hydraulic pump converts the mechanical energy of the drive motor into the pressure energy of the oil. It is the power device in the hydraulic system, and the hydraulic pump and the motor hydraulic machine commonly used in the hydraulic system. They are all volumetric, and their working principle is to absorb and press oil by changing the sealing volume. From the working principle, most hydraulic pumps and hydraulic motors are reciprocal, that is, the input pressure oil, the hydraulic pump becomes a final drives, can output the speed and torque, but in terms of structure, the hydraulic pump and the hydraulic motor are still Some differences. Maintenance of hydraulic press: The disassembly and assembly of the interference fit is provided by the hammer knocking, the stick sledge, the labor intensity is low and the safety is not safe, the parts are easy to be broken, and the operation method of heating is difficult and the maintenance cost is increased. At the top of the bracket, a hydraulic cylinder with a piston rod vertically downward is mounted, and a lower end of the piston rod is mounted with a pressure head; a bracket is placed on a lower portion of the piston rod, and a work table is horizontally fixed; a hydraulic motor and an oil pump connected to the oil pump pass through The reversing valve is connected to the hydraulic cylinder. With the pressure of the hydraulic cylinder to load and unload parts, there is no violent hammering and sledding, no damage to the parts, no heating and energy consumption, safe and reliable energy saving, high installation precision.
The hydraulic motor converts the pressure energy of the oil into mechanical energy. It is the actuator in the hydraulic system. It can be seen that it is the core device in the hydraulic system. https://www.spfinaldrives.com/
