Tools/materials: oil-water separator, pipeline and valve.

1. First, the oil-water separator should be installed near the material to be purified to minimize the pressure loss in the pipeline.

2. The pipelines for discharging oil and water should also be shortened as far as possible, and the oil pollution tank should be as close to the equipment as possible and lower than the equipment.

3. In order to prevent large particles of impurities from damaging the oil-water separator, a primary filter should be set in front of the equipment.

4. Before the equipment is officially used, be sure to connect the relevant roads and close the drain valve.

5. Before starting the machine, confirm whether the rotation direction of the motor is correct. If the rotation direction is wrong, adjust the line sequence in time.

6. After the equipment enters the normal working state, observe whether there is oil pollution flowing out from the sewage outlet.
