Mainly from three aspects to master the precision CNC CNC machining of CNC machine tool oil pressure system abnormal causes and solutions:.
(1) the oil pump is not the main reason for the oil pump may be the low level in the tank, the oil pump flip, the speed is too low, the oil viscosity is too high, the oil temperature is too low, the filter is blocked, the suction pipe tube capacity is too large, the import suction, shaft and rotor damage, etc. The main reasons have corresponding solutions, such as oil filling, determine the sign, oil pump flip, etc.
(2) Abnormal pressure, i.e. too high or too low pressure. There are also many main causes such as improper pressure setting, poor pressure regulating valve coil operation, abnormal air pressure gauge, and leakage of oil pressure system. The corresponding solution is to disassemble and clean according to the prescribed pressure setting, replace the normal air pressure gauge, and check according to each system.
(3) The key to the noise generated by oil pumps and valves. When the valve noise, the reason is that the flow rate exceeds the rated specification, the flow rate should be properly adjusted; when the oil pump noise, the reasons and corresponding solutions are also many aspects, such as pneumatic CNC machining of high oil viscosity, low oil temperature, oil temperature rise, system gas release, etc.
