The working principle of the single-column hydraulic press
A single-column hydraulic press is a device that uses liquid to transmit pressure. Liquids obey Pascal's law when they transmit pressure in a closed container. The hydraulic transmission system of the hydraulic press consists of a power mechanism, a control mechanism, a performance mechanism, an auxiliary mechanism and a working medium. Power arrangement Generally, an oil pump is used as the power arrangement, which is generally a positive displacement oil pump. In order to meet the requirements of the scheduled movement speed, choose one oil pump or multiple oil pumps. Gear pump for low pressure (oil pressure less than 2.5MP); vane pump for medium pressure (oil pressure less than 6.3MP); plunger pump for high pressure (oil pressure less than 32.0MP). Hydraulic machines generally refer to hydraulic pumps and hydraulic motors. Both hydraulic pumps and hydraulic motors are energy conversion equipment 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 equipment in the hydraulic system. The hydraulic motor converts the pressure energy of the oil into mechanical energy and is the performance equipment in the hydraulic system.
