What is the principle of a hydraulic press
Hydraulic press is a mechanical equipment that uses the static pressure of liquid to transmit energy to complete various processing processes. It is widely used in metal molding, plastic pressing, powder metallurgy and other fields. This article will introduce in detail the working principle of the hydraulic press, and combine the popular topics and hot contents of the entire network for the past 10 days to present you a structured popular science article.
1. Basic principles of hydraulic press
The working principle of hydraulic press is based onPascal's Law, that is, the pressure change in the closed container will be evenly transmitted to the fluid at any point. The hydraulic press applies pressure through a small piston, and uses the incompressible liquid to transmit pressure to the large piston, thereby achieving amplification of force.
| Part Name | Function description |
|---|---|
| Hydraulic pump | Convert mechanical energy into hydraulic energy |
| Hydraulic cylinder | Convert hydraulic energy into mechanical energy |
| Control valve | Adjust the flow direction and pressure of hydraulic oil |
| tank | Storage of hydraulic oil and cooling system |
2. The core advantages of hydraulic presses
1.Force amplification effect: Amplification of force is achieved through the area ratio of the pistons of large and small
2.Stable transmission: Hydraulic oil has extremely low compressibility and stable movement
3.Overload protection: The maximum working pressure can be set through the safety valve
4.Wuji speed adjustment: Speed adjustment is achieved through flow control valve
