What should I do if there is abnormal lubrication in Ningbo Easy Forging Press?

When the lubrication is abnormal, you must stop the machine for inspection first, and then start working after troubleshooting. The 60-ton punch is a pneumatic friction clutch punch. It uses electric heavy oil pump to pump grease into the oil separator, which distributes it to all lubricating points according to the designed flow rate, thus lubricating the motion pair. When the oil pump starts pumping oil, the valve core on the oil separator will swing, and the microswitch on it will trigger a pulse signal to the PLC control system. If the signal is normal within the specified time, if the signal is abnormal, PLC will give an alarm. There are several possibilities for abnormal lubrication alarm failure of punch press: 1, the lubricating oil level is too low, and the oil suction port can't suck oil, so it is necessary to refuel to the upper limit position in time. If there is air in the lubricating oil, the oil pressure will not rise. The air in the oil should be exhausted, and there is an exhaust button or plug on the oil pump. 3. Some lubricating points are blocked. Generally, progressive oil distributors are used for oil distribution in punch presses. If one lubrication point is blocked, the whole oil circuit will be blocked. It is necessary to check the oil path and lubrication points. After finding the fault point, it can be solved by cleaning. It is recommended to find a professional maintenance master to help solve it. 4. In addition, it is also possible that the wiring of the oil pump motor is reversed during debugging, and even if the motor is reversed, oil cannot be pumped (gear pump). You can follow the above steps to solve the problem.
