[CNC machine for sale]Oil pump fault treatment for CNC machine tool

Oil pump fault treatment for CNC machine tool shared by CNC machining service China.

Such as when the pump does not spray oil, pressure is not normal, noise and other phenomena, should know what the main reasons are, what is the corresponding solution.

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

(1) pump injection not the main reason may be the tank liquid level is low, oil pump reversal, low speed, high oil viscosity, the oil temperature is low, and blockage of the filter, vacuum tubing pipe volume is too large, the inlet of air, shaft and rotor frayed, etc., has corresponding solutions to the main reason, the wound with oil, confirm sign, when oil pump reverse change to come over, etc.

(2) CNC milling service China points out that abnormal pressure means that the pressure is too high or too low. The main reasons are various, such as improper pressure setting, bad pressure regulating valve coil action, abnormal pressure gauge, oil pressure system leakage. The corresponding solution is to disassemble and clean according to the specified pressure setting, replace a normal pressure gauge, and inspect each system in turn.

(3) noises are mainly caused by oil pumps and valves. When the valve is noisy, the reason is that the flow exceeds the rated standard, the flow should be adjusted appropriately; When there is noise in the oil pump, the reasons and corresponding solutions are also various, such as high viscosity of oil, low oil temperature, the solution is rising oil temperature; When there are bubbles in the oil, air should be released from the system and so on.
