The Working Principle Of Four-column Hydraulic Press

The hydraulic transmission system of a four-column hydraulic press consists of a power mechanism, a control mechanism, an executive mechanism, an auxiliary mechanism and a working medium. The power mechanism usually uses an oil pump as the power mechanism, which is generally a product oil pump. In order to meet the requirements of the motion speed of the actuator, one oil pump or multiple oil pumps are selected. Gear pumps for low pressure (oil pressure less than 2.5MP); vane pumps for medium pressure (oil pressure less than 6.3MP); plunger pumps for high pressure (oil pressure less than 32.0MP). Pressure processing and forming of various plastic materials, such as extrusion, bending, stretching of stainless steel plate and steel plate and cold forming of metal parts. It can also be used for the pressing of powder products, grinding wheels, bakelite, and resin thermosetting products.
