Solutions to the failure of hydraulic chuck of Shandong CNC lathe
There is too little hydraulic oil in the oil tank of Shandong CNC lathe hydraulic station, which leads to the idling of the hydraulic pump due to lack of oil. The hydraulic oil in the oil tank of the hydraulic station has not been replaced for a long time, and dirt enters the oil, causing the hydraulic oil to be too high and produce abnormal noise. As the output oil pipe of the hydraulic pump station is blocked somewhere, hydraulic shock and sound are produced. The connection between the hydraulic pump and the hydraulic motor is loose and makes a sound.

Solutions to the failure of hydraulic chuck of Shandong CNC lathe:

After inspection, it was found that after the hydraulic pump was started, the pressure at the outlet of the hydraulic pump was at 0, the oil level in the oil tank was at the normal position, and the hydraulic oil was relatively clean. The hydraulic pump was further disassembled for inspection, and it was found that the hydraulic pump was a vane pump, the vane pump was normal, and the hydraulic motor rotated normally. Therefore, the hydraulic pump and hydraulic motor bearings are normal. The coupling between the hydraulic pump and the hydraulic motor is a nylon tooth coupling. Due to the long trial time of the equipment and the high adjustment of the output pressure of the hydraulic station, the meshing teeth of the coupling are damaged. When the hydraulic motor rotates, the coupling cannot transmit torque well, resulting in abnormal noise.
