After half a year, the hydraulic system of the machine tool, the spindle lubrication system and the X-axis should be inspected. If there is a problem, the new oil should be replaced and then cleaned. After thoroughly familiarizing with and mastering the knowledge of preventive maintenance, you must have a deeper understanding and necessary grasp of the causes and treatment of abnormal phenomena in the hydraulic system. For example, when the oil pump does not spray oil, the pressure is abnormal, there is noise, etc., you should know what are the main reasons and what is the corresponding solution.

The causes and treatment of abnormal phenomena in the hydraulic system should be understood from three aspects:

(1) The main reason for the oil pump not to be injected may be low liquid level in the fuel tank, reverse oil pump, low speed, high oil viscosity, low oil temperature, filter blockage, excessive suction pipe capacity, and suction at the oil inlet. There are damages to the air, shaft, and rotor. For the main reasons, there are corresponding solutions, such as filling the oil, confirming the sign, and changing when the oil pump reverses.

(2) The pressure is abnormal. The pressure is too high or too low. The main reasons are also various, such as improper pressure setting, poor operation of the pressure regulating valve coil, abnormal pressure gauge, and leakage of the hydraulic system. The corresponding solution is to open and clean according to the specified pressure setting, change to a normal pressure gauge, and check according to each system.

(3) Noise There is mainly noise generated by oil pumps and valves. When the valve is noisy, the reason is that the flow rate exceeds the rated standard, and the flow should be properly adjusted; when the oil pump has noise, the reason and the corresponding solution are also various, such as high viscosity of oil and low oil temperature, solution To raise the oil temperature; when there are air bubbles in the oil, the air in the system should be released.
