From July 28 to August 1, 1978, YZ series modular hydraulic press station assessment meeting was held in Guangzhou City. At the meeting, there were 41 representatives from 32 units. Hydraulic Station is a machine designed by the Guangzhou Institute of Tropical Machines, Guangzhou Hydraulic Factory and Hunan Machinery Industry Design Institute and other units jointly designed, the tank capacity of 63,100,160,250 liters of four specifications, the working pressure of 50 kg force / cm ~ 2. Hydraulic station pump device has vertical, horizontal two, the use of variable displacement vane pump pump, pump and double quantitative. The integrated circuit of the hydraulic station consists of medium and low pressure hydraulic control valves and manifolds. During the meeting,
