Working principle and components of customized hydraulic system

Hydraulic technology is based on the liquid as the working medium, using the static pressure of the closed system liquid to realize the transmission of information, motion and power and engineering control technology. Hydraulic technology has unique technical advantages in power quality ratio, structural composition, response speed, speed adjustment range, overload protection and electro-hydraulic integration, etc., so it has become an important technical means of modern transmission and control and one of the important basic technologies that cannot be replaced, and its application covers all fields of the national economy. Let's understand the working principle and components of the customized hydraulic system together!

The principle of custom hydraulic systems can generally be analyzed by the following methods:

1) The hydraulic components in the system diagram are mainly: fuel tank, motor, hydraulic pump, oil pipe, air cooling, variable piston pump, internal gear pump, pressure gauge, external gear pump, hydraulic pump, joint, variable vane pump, quantitative vane pump

2) Analyze the path of controlling the oil flow of the oil circuit, and the control and operation of the machine it controls on the motion state of the oil cylinder. Such oil circuit is called auxiliary oil circuit. The route of oil flow in the auxiliary circuit should also be from the power element to the control element. In addition, the oil pool is returned from the control element to form a complete cycle. In general, the pressure of the auxiliary circuit is slightly lower than that of the main circuit.

3) Understand the cycle process of the machine tool, understand the movement and action required by the machine tool for the hydraulic system, and the mechanical requirements for the system performance. To analyze the working principle of the hydraulic system, read the hydraulic system diagram.

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

The movement and operation period of the actuator of the customized hydraulic system are realized through the change of the oil flow path of the main circuit. The change of the main circuit oil flow path is also called the control unit within the auxiliary circuit, in the analysis of the working principle of the hydraulic system, especially when the tired system is transferred from one working state to another working state, from which control unit to send a signal, from which hydraulic valve or other control unit

When hydraulic driven and controlled mechanical equipment or devices work, the customized hydraulic system has continuous flow of working oil or flame retardant working oil or water (mostly using working oil) as the working medium, so that the hydraulic pump drives the prime mover of the pump) motor or internal combustion engine) the mechanical energy of the liquid pressure energy is transmitted to the actuator through the closed pipeline and control valve. It is converted into mechanical energy to drive the load and achieve the linear motion, rotational motion or swing required by the action mechanism.
