1. Pascal's law acts on the pressure of a closed fluid to be transmitted from the fluid to all parts of the container without changing the size. The basic principle of the hydraulic machine is that the oil pump delivers the hydraulic oil to the integrated cartridge valve block, and distributes the hydraulic oil to the upper cavity or lower cavity of the cylinder through various one-way valves and overflow valves, and makes the cylinder move under the action of high pressure oil.
2. The hydraulic press is a machine made by Pascal's law that uses liquid pressure to drive. The hydraulic cylinder and surrounding environment should be clean, and the oil tank should be sealed to prevent contamination. Pipelines and fuel tanks should be cleaned to prevent falling off iron oxide scale and other debris. Use lint-free cloth or special paper for cleaning. Cannot use twine and adhesives as sealing materials.
3. Hydraulic presses that use water-based liquid as working medium are called hydraulic presses, and those that use oil as working medium are called hydraulic presses. The single-arm hydraulic machine frame is an integral cast steel structure or a steel plate welded structure. The structure is simple, and the workpiece can be approached from three directions when working, and the operation is simple and convenient. In order to ensure that the frame has sufficient strength and rigidity, sometimes the frame is made relatively heavy, but the accuracy of the machine stamping and calibration work is guaranteed.
