Hydraulic walking system is a kind of system that realizes mechanical movement by using hydraulic principle. It is mainly composed of hydraulic pump, hydraulic motor, hydraulic cylinder, hydraulic valve, and oil tank. The hydraulic walking system is widely used in various construction machinery, such as excavators, loaders, bulldozers, etc. It has the characteristics of flexibility, efficiency, and stability.
The hydraulic pump is the core of the hydraulic walking system, which compresses the oil through mechanical force to produce a certain pressure, and then transfers the high-pressure oil to the hydraulic motor to make the hydraulic motor start to rotate. Hydraulic motor is a device that converts hydraulic energy into mechanical energy, which can convert high-pressure oil into rotating torque, thereby driving the movement of machinery. The speed of the hydraulic motor can be adjusted by the hydraulic valve.
The hydraulic cylinder is another important part of the hydraulic walking system, which can convert the hydraulic energy into linear motion to realize the mechanical movement. The hydraulic cylinder is usually composed of piston, cylinder block, seal, and an actuator, and its stroke can be realized by adjusting the hydraulic valve.
The hydraulic valve is the control center of the hydraulic walking system, which can adjust the pressure, flow, and direction of the output of the hydraulic pump, to control the operation of the hydraulic motor and hydraulic cylinder. Hydraulic valves usually have a variety of types, such as check valves, safety valves, speed regulating valves, reversing valves, etc., which can be combined according to the needs of machinery.
The oil tank is the oil reservoir of the hydraulic walking system, which is used to store hydraulic oil and transport it to various parts of the system through tubing. The tank usually has an oil inlet, an oil outlet, an exhaust hole, an oil level meter, and other parts, which are designed to have good sealing, filtering, and heat dissipation.
The hydraulic walking system has many advantages, such as being able to achieve efficient and flexible mechanical movement, with high accuracy and stability, suitable for a variety of harsh working environments. But there are also some problems, such as hydraulic oil leakage, and system maintenance is difficult. Therefore, when using the hydraulic walking system, it is necessary to pay attention to the maintenance and maintenance of the system to ensure its normal operation and extend its service life.
