The hydraulic system is a combination of various hydraulic components organically connected with pipelines in accordance with the transmission requirements of the heavy equipment's working device. The function of the hydraulic system is to use oil as the working medium and use the hydraulic pump to convert the mechanical energy of the engine into hydraulic energy and transmit it. Then the hydraulic cylinder and hydraulic motor will convert hydraulic energy into mechanical energy to realize various movements of heavy equipment.
