Working principle of hydraulic press

Hydraulic press is a kind of mechanical equipment that uses liquid to transfer pressure to achieve work. It is mainly composed of hydraulic system, workbench, hydraulic cylinder, control system and so on. The working principle of the hydraulic press is based on PASCAL's law, which states that in a closed liquid system, the pressure applied to the liquid will be evenly transmitted to all parts of the system.

The working principle of the hydraulic press can be simply described as the following steps:

1. Hydraulic system oil supply: The hydraulic press extracts the liquid (usually oil) from the tank through the hydraulic pump and transmits it to the hydraulic cylinder through the pipeline. The pressure produced by the hydraulic pump gives the liquid a certain energy.

2. Pressure transfer: The pressure provided by the hydraulic pump makes the liquid transfer in the hydraulic system. The liquid enters the hydraulic cylinder through the pipe and exerts pressure on the hydraulic cylinder at the same time.

3. Hydraulic cylinder work: After the liquid enters the hydraulic cylinder, the pressure makes the piston move in the hydraulic cylinder. The structure of the hydraulic cylinder is designed so that the movement of the piston generates the required force and displacement.

4. Workbench operation: The hydraulic press's workbench is usually installed on the piston of the hydraulic cylinder. When the piston moves, the workpiece on the workbench moves with it. By adjusting the pressure and displacement of the hydraulic cylinder, the machining, forming and pressing of the workpiece can be realized.

5. Control system: The control system of the hydraulic press is used to control the work of the hydraulic pump and the movement of the hydraulic cylinder. The control system can use manual operation, automatic control or computer control to achieve accurate control of the hydraulic press.

The working principle of the hydraulic press has the following advantages:

1. Large force: Due to the incompressible characteristics of the liquid, the hydraulic press can provide a lot of force, which is suitable for processing large workpieces or processing operations requiring high pressure.

2. High flexibility: the working pressure and displacement of the hydraulic press can be controlled by adjusting the parameters of the hydraulic pump and the hydraulic cylinder, so as to achieve accurate control of the workpiece and a variety of processing operations.
