CNC vertical lathe is a high-precision machine tool, and its oil pump, as one of its power sources, plays a key lubrication and cooling role. However, sometimes we find abnormal noise in the oil pump. How should we deal with it?

First of all, the root cause of abnormal noise in the oil pump is that the oil enters the oscillation zone from the gap between the inlet and outlet of the oil pump, causing deformation inside the oil pump. This deformation causes tiny movements between the oil pump and other related parts, causing abnormal noise.

To deal with this problem, we can deal with it from the following aspects:

1. Check the oil: Abnormal noise may be caused by problems with the oil. It is recommended to remove the oil pump for inspection and replacement.

2. Adjust the position of the oscillation zone: By adjusting the position of the oscillation zone, the tiny movements between the oil pump and other components can be reduced, thereby avoiding the occurrence of abnormal noise. This approach requires experimentation and testing to find the sweet spot.

3. Lubricating the working surface: Movement between the oil pump and other related parts is often caused by insufficient lubrication. By enhancing the lubrication of the lubricating working surface, the probability of abnormal noise can be reduced.

4. Replace parts: If none of the above methods can solve the abnormal noise problem, the last resort is to replace the oil pump or other related parts to eliminate the problem.

In short, the abnormal noise of the CNC vertical lathe oil pump is a relatively common problem, but we can avoid and solve this problem by taking the above measures to ensure the efficient operation of the machine tool.
