Principle of single column hydraulic press

Single column hydraulic press in the process of work, the role of the working substance is to transfer pressure, to ensure that the working parts of the equipment work sensitive, reliable, long life and less leakage.

The basic requirements of single-column hydraulic press for working substances are

1, there is a suitable fluidity and low compressibility, in order to improve the efficiency of transmission;

2, can prevent rust;

3, have good lubrication performance;

4. Easy to seal;

5, stable performance, long-term work and no deterioration.

The single-column hydraulic press is changed to emulsified oil made by adding a small amount of emulsion in water to enhance lubricity and reduce rust. Oil has good lubricity, corrosion resistance and appropriate viscosity, which is beneficial to improve the performance of single column hydraulic press. Its lubricity and corrosion resistance are close to oil, and the oil content is very small, and it is not easy to burn. But the water emulsified oil price is expensive, limiting its promotion.

Working principle of single column hydraulic press

Single column hydraulic press is the use of liquid to transfer pressure equipment. The liquid state follows Pascal's law when transferring pressure in a closed container. The hydraulic control system of the hydraulic press is composed of the power mechanism, the control mechanism, the implementation mechanism, the assistance mechanism and the working substance. The power mechanism generally uses an oil pump as the power mechanism, generally a volumetric oil pump. In order to meet the needs of the speed of movement of the implementation mechanism, an oil pump or several oil pumps are used. Low pressure (oil pressure below 2.5MP) with gear pump; high pressure (oil pressure below 6.3MP) with vane pump; high pressure (oil pressure below 32.0MP) with plunger pump.

Hydraulic machines usually refer to hydraulic pumps and oil motors. Hydraulic pumps and hydraulic motors are energy conversion devices in the hydraulic system. The difference is that the hydraulic pump converts the mechanical energy of the driving motor into the pressure energy of the oil, which is the power system in the hydraulic system. The oil motor converts the pressure energy of the oil into mechanical energy and is the executive device in the hydraulic system.
