As we all know, the hydraulic system plays an important role in the hydraulic industry and is an indispensable system. The system in practical application is generally composed of hydraulic pumps, hydraulic valves, hydraulic actuators and accessories. details as follows:
1. The hydraulic pump discharges hydraulic oil driven by the electric motor or engine.
2. The hydraulic actuator is connected with the working parts and is driven by the hydraulic oil to drive the working parts.
Drive, usually refers to the movement of working parts. The hydraulic actuator has another task: to make the working parts from moving to immobile, that is, to brake. In this book, driving and braking are collectively called control, and the working parts that need to be controlled by hydraulic actuators are collectively called loads.
Controlling the movement of the load is the basic task on which hydraulic technology depends.
To control the movement of the load, it is necessary to overcome various resistances that affect the movement. Therefore, in this book, the various resistances overcome by hydraulic actuators are collectively referred to as load forces.
Hydraulic actuators are divided into hydraulic cylinders and hydraulic motors.
Generally speaking, the hydraulic cylinder controls the linear movement of the load and overcomes the load force; the hydraulic motor controls the rotation or swing of the load and overcomes the load torque. For the sake of brevity, the following generally refers to hydraulic actuators with hydraulic cylinders, which generally only increase the load force and omit the load torque.
According to national standards, a motor refers to "an executive element that provides rotary motion", including hydraulic motors and pneumatic motors.
Since this book does not involve pneumatics, the hydraulic motor is referred to as "motor" hereinafter.
3. The hydraulic valve is used to restrict the flow of hydraulic oil to control the movement of the hydraulic actuator.
4. Auxiliary parts include connecting pipes, fuel tanks, filters, heaters, coolers, indicating instruments, etc.
Because the liquid does not have a fixed shape, hydraulic actuators, hydraulic valves and hydraulic accessories can be arranged wherever needed, as long as the hydraulic pipeline can be passed through, there is no restriction on direction and distance. Therefore, it is very flexible.
