1. The machine primarily employs mechanical filtration, utilizing filter screens with progressively finer mesh to achieve higher filtration precision. Consequently, during operation, the first-stage filter is prone to clogging by impurities; when this occurs, the oil inflow rate will drop below the outflow rate.
Remedy: Remove the top cover of the first-stage filter, take out the screen, clean it with the same type of clean oil, and then reinstall it to resume operation.
2. If the pumping head (lift) is excessive during the oil transfer process, the motor temperature will rise rapidly, and the oil pump noise will increase.
Remedy: 1. Operate within the specified pumping head limits; 2. Use intermittent operation.
3. Abnormal increase in oil pump noise:
Remedy: 1. Check the alignment (concentricity) of the oil pump connecting shaft; 2. Check for loose or missing fastening screws. Rectifying these issues will resolve the problem.
4. Operation with missing phases is strictly prohibited to prevent burning out the motor.
