The causes and treatment of the abnormal phenomenon of the hydraulic system of CNC lathe processing equipment should be understood from three aspects: (1) The oil pump of the CNC lathe processing equipment does not spray oil The main reasons 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, suction air at the inlet, shaft and rotor. For damages, etc., there are corresponding solutions to the main reasons, such as filling the oil, confirming the signage, and changing when the oil pump reverses. (2) The pressure of the CNC lathe processing equipment is abnormal That is, the pressure is too high or too low. The main reasons are 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 of CNC lathe processing equipment Noise is mainly 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 rate should be properly adjusted; when the oil pump is noisy, the cause 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.
