The working principle and components of the customized hydraulic system

Hydraulic technology has unique technical advantages in terms of power quality ratio, structural composition, response speed, speed regulation range, overload protection and electro-hydraulic integration. Therefore, it has become an important technical means and an irreplaceable fundamental technology in modern transmission and control. Its application covers all fields of the national economy. Then, Let's take a look at the working principle and components of the customized hydraulic system together!

The principle of a customized hydraulic system can generally be analyzed through the following methods:

The main hydraulic components in the system diagram include: oil tank, motor, hydraulic pump, oil pipe, air cooler, variable piston pump, internal gear pump, pressure gauge, external gear pump, hydraulic pump, connector, variable vane pump, and fixed vane pump

2) Analyze the path that controls the oil flow in the oil circuit, as well as the control and operation of the movement state of the oil cylinder by the machine it controls. Such an oil circuit is called an auxiliary oil circuit. The flow path of the auxiliary circuit oil should also be from the power components to the control components. In addition, it returns to the oil pool from the control element, forming a complete cycle. Generally speaking, the pressure in the auxiliary circuit is slightly lower than that in the main circuit.

3) Understand the cycle process of the machine tool, the movement and action required by the machine tool for the hydraulic system, as well as the mechanical requirements for system performance. It is to analyze the working principle of the hydraulic system and read the hydraulic system diagram.

4) Analyze the working cycle process of each cylinder in the execution department and the corresponding oil flow path of the main circuit. The circuit that drives the cylinder is the main circuit. The flow path of the oil in the main circuit must form a complete cycle from the oil pump to the oil cylinder and then from the oil cylinder to the oil tank. The cylinder completes the movement required by the system under the action of the hydraulic oil in the main circuit.

The various movements and action cycles of the customized hydraulic system actuator are achieved through the changes in the oil flow path of the main circuit. The change of the main circuit oil flow path is also known as the control unit within the auxiliary circuit. In the analysis of the working principle of the hydraulic system, especially when a tired system transitions from one working state to another, which control unit sends the signal from, which hydraulic valve or other control unit sends the signal

When mechanical equipment or devices driven and controlled by hydraulic power are in operation, the customized hydraulic system uses continuously flowing working oil or flame-retardant working oil or water (working oil is mostly used) as the working medium. The mechanical energy of the prime mover (electric motor or internal combustion engine) driven by the hydraulic pump and the pressure energy of the liquid are delivered to the actuator through closed pipelines and control valves. It is converted into mechanical energy to drive the load, achieving the linear motion, rotational motion or swing required by the action mechanism.
