What is the working principle of single column hydraulic press


  single column hydraulic pressIt is a device that uses liquid to transmit pressure. When the liquid transmits pressure in a closed container, it follows Pascal's law. The hydraulic transmission system of a single-column hydraulic press is composed of a power mechanism, a control mechanism, a driver, an auxiliary mechanism and a working medium. Let's learn about it. What is the working principle of a single-column hydraulic press!

 single column hydraulic pressThe structure usually uses an oil pump as the power mechanism, usually a volumetric oil pump. In order to meet the movement speed requirements of the drive, one oil pump or multiple oil pumps are selected. Low pressure (hydraulic less than 2.5MP) with gear pump; medium pressure (hydraulic less than 6.3MP) with vane pump; high pressure (oil pressure less than 32.0MP) with plunger pump.

  single column hydraulic pressGenerally refers to hydraulic pumps and hydraulic motors. Both 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 device in the hydraulic system.

The hydraulic pumps and hydraulic motors commonly used in hydraulic systems are volumetric, and their working principle is to use the change of the seal volume to attract oil, thereby starting the pressure oil. From the working principle, most hydraulic pumps and hydraulic motors are opposite to each other. In other words, after the pressure oil is input, the hydraulic pump becomes a hydraulic motor, which can output speed and torque, but from the structural point of view, the hydraulic pump and the hydraulic motor are slightly different.

  single column hydraulic pressIt has independent power mechanism and electrical system, and adopts button centralized control, which can realize the stroke and range of mechanical working pressure, stamping speed, no-load rapid downward and deceleration in three working modes of adjustment, manual and semi-automatic, and can be adjusted according to process requirements. The extrusion process can have three process modes of extrusion process, each process is constant pressure, and the two process actions of fixed process are optional, extrusion forming process after extrusion with extrusion delay and automatic single column hydraulic press has a wide range of versatility, processing and forming of various plastic materials, for example, in addition, hydraulic press can also be used for various plastics, powder products stamping forming. In addition, the single-column hydraulic press can also be used for product correction, pressing, shaping, etc.
