Hydraulic power unit how it works，Vertical mill hydraulic station is a vertical mill roll pressurisation hydraulic station, mainly used for vertical mill roll pressurisation cylinders and maintenance cylinders pressurisation and control of the direction of movement, then the vertical mill hydraulic station is specifically how to work, the following for you to explain the working principle of the vertical mill hydraulic station.hydraulic power unit how it works
Working principle of vertical mill hydraulic station:
Motor through the coupling drive gear pump through the oil filter from the tank oil suction, gear pump output high pressure through the high-pressure oil pipe into the control valve block, into the control valve block of high-pressure oil filtered by the pressure filter all the way into the proportional relief valve mouth, proportional relief valve role is through the proportional amplifier remote control of the hydraulic station’s working pressure.
Another way involves high-pressure oil entering the electromagnetic directional valve mouth. From there, it flows into the liquid control check valve. The oil then passes through the electromagnetic ball valve and the control valve block outlet. Next, it travels through the high-pressure oil pipe into the shut-off valve. The oil then moves through the plate ball valve and into the hydraulic system. Finally, it enters the rod chamber of the main cylinder and the accumulator. At this point, the grinding rollers in the main cylinder piston rod begin to work.
In addition to providing stable grinding pressure for the vertical mill, the vertical mill hydraulic station also has other functions. It is used for lifting and landing the pressure frame when the mill is under repair. Furthermore, it facilitates the adding, discharging, and circulating filtering of hydraulic oil.
