What are the outstanding advantages of hydraulic press?

Hydraulic press is a kind of liquid as the working medium, according to the principle of PASCAL made for the transfer of energy to achieve various processes of the machine. Hydraulic press is generally composed of three parts: the machine (main engine), power system and hydraulic control system. Hydraulic press classification valve hydraulic press, liquid hydraulic press, engineering hydraulic press.

The outstanding advantages of hydraulic press are:

1, the work is stable, the impact and vibration is very small, the noise is small, which has great benefits for the health of workers, the foundation of the plant, the surrounding environment and the equipment itself.

2. Easy to adjust pressure and speed. The hydraulic press uses the pressure of the working liquid to transfer energy, and can adjust the pressure and limit the pressure by adjusting various pressure control valves, and can reliably prevent overload, which is conducive to protecting the mold and equipment. The adjustable range of the moving speed of the movable beam is large, and it can adapt to the different requirements of the working speed in different processes.

3, easy to get a larger total pressure and larger working space. This is the outstanding advantage of hydraulic press. Based on the principle of hydraulic transmission, the actuator structure of the hydraulic press is simple, and the power equipment can be arranged separately, can work with multiple cylinders, and the liquid pressure and the working area of the piston (or plunger) can be changed in a large range. And because the hydraulic press is a static pressure equipment, it does not need a large foundation, so it can achieve a large tonnage. At present, all kinds of forming equipment, where the need for larger pressing tonnage more than the use of hydraulic press, hundreds of thousands of cattle above almost all are hydraulic press.

4, easy to get a large working stroke, easy to press large size workpiece, and can produce rated large pressure at any position of the stroke, can be maintained for a long time. This characteristic of the hydraulic press is necessary for some processing processes, such as deep drawing, extrusion, plastic molding, superhard material synthesis, etc.
