A hydraulic system is a mechanical system that uses fluids to transfer energy and is commonly used in a variety of engineering and industrial applications.

First, hydraulic system components

1. Hydraulic pump: usually driven by motor or engine, used to produce flowing hydraulic fluid. It sucks the liquid from the tank and compresses it, and then delivers the high-pressure liquid to the hydraulic system.

2. Hydraulic tank: Used to store hydraulic oil and usually contains a filter and oil level indicator. It ensures that there is always enough liquid in the system and helps to cool the hydraulic oil.

3. Hydraulic valve: control liquid flow and pressure to perform various functions. Common hydraulic valves include control valves, directional valves, relief valves, proportional valves and so on.

4. Hydraulic cylinder: It is an executive mechanism that converts liquid pressure into linear motion. They are commonly used to drive various mechanical devices, such as lifts, excavator arms, etc.

5. Hydraulic motor: similar to the hydraulic cylinder, the liquid pressure is converted into rotating motion. They are often used to drive a variety of rotating equipment, such as conveyor belts, fans, etc.

6. Hydraulic lines and fittings: Hydraulic lines are used to transport liquids and connect various components in the system. Pipe fittings include joints, elbows, flanges and quick joints, etc.

7. Hydraulic filter: used to remove pollutants and impurities to ensure the clean oil and normal operation of the system.

8. Pressure gauges and sensors: These are used to monitor the hydraulic pressure in the system for control and fault diagnosis.

9. Emergency cut-off valve: In an emergency, these valves can be used to quickly cut off the fluid flow of the hydraulic system to prevent accidents.

10. Accumulator: Used to store liquid pressure energy in order to release additional energy when needed to perform quick actions or buffer the system.

Two, hydraulic pump type and characteristics

A gear pump is a fluid accumulation pump that uses one or more pairs of gears (usually gears or gears) to rotate inside the pump in order to draw fluid from the inlet and discharge it through the outlet. When the gear rotates, the liquid is squeezed out. Gear pumps are commonly used in hydraulic systems for lubrication, liquid transfer, and low to moderate pressure applications.

The vane pump uses the vane to rotate in a slot inside, drawing the liquid from the inlet and discharging it through the outlet. The slide can be bent to fit the pump housing shape. Vane pumps are commonly used in liquid transfer and lubrication systems in industrial applications, as well as in automotive braking systems.

The plunger pump uses the plunger to move back and forth in the pump to suction and discharge the liquid. These plungers can move individually or in groups, depending on the type of pump. Plunger pumps are widely used in hydraulic systems that require high pressure and high precision control, such as construction machinery, aerospace and industrial machinery.
