How to operate a lubricating oil purifier?

Operating a lubricating oil purifier requires proper setup, monitoring, and safety practices. Below are general steps for safely and effectively running a typical centrifugal-type lubricating oil purifier:

 1. Preparation

   - Inspect the Equipment: Check for any visible damage or leaks in the purifier, piping, and valves. Ensure all parts, including the filters and seals, are properly fitted.

   - Prepare the Oil Source and Collection Tanks: Ensure oil inlet and outlet tanks are clean, and that valves are in the correct positions.

   - Check Power and Safety Systems: Confirm that power sources, emergency stops, and alarm systems are functional. Ensure proper grounding to prevent electrical hazards.

 2. Pre-Heating the Oil (if required)

   - Heat the Oil: Many purifiers require oil to be preheated to reduce its viscosity and make purification more efficient. Set the temperature according to the machine’s specification, typically between 60–90°C (140–194°F).

   - Verify Temperature: Check that the oil reaches the target temperature before starting the purifier, as temperature affects separation efficiency.

 3. Starting the Purifier

   - Start the Machine Slowly: Begin by slowly opening the inlet valve to let oil flow into the purifier chamber without overwhelming it. Ensure the system pressure is within operating limits.

   - Engage the Centrifugal Separator: Start the centrifugal unit, allowing it to build up to its operating speed. The centrifugal force will help separate contaminants based on density.

   - Adjust Flow Rate: Set the oil flow rate according to the purifier’s specifications. A slower rate typically allows better separation, so adjust as needed based on oil type and contamination level.

 4. Monitoring Operation

   - Check Pressure and Flow: Continuously monitor gauges for proper pressure and flow rates. Adjust if needed to maintain consistent flow through the purifier.

   - Inspect Outlet for Clarity: Periodically check the outlet oil for clarity. If it appears cloudy, it could indicate water or impurities are not fully separated.

   - Monitor Water and Sludge Discharge: In purifiers with automatic discharge, monitor the sludge and water discharge intervals and collection containers. Ensure that sludge and water are effectively removed.

 5. Stopping the Purifier

   - Gradually Reduce Flow Rate: Before shutting down, gradually reduce the oil inflow rate to prevent pressure surges.

   - Stop the Centrifugal Separator: Once the oil flow stops, turn off the centrifugal unit, allowing it to come to a complete stop naturally.

   - Close Valves and Drains: Close all inlet and outlet valves. Drain any remaining water or sludge from the purifier, if applicable.

 6. Maintenance and Cleaning

   - Clean Separator Components: Disassemble and clean the bowl, nozzles, and filters periodically, following manufacturer instructions.

   - Inspect Seals and Bearings: Lubricate or ｒｅｐｌａｃｅ seals and bearings as needed to prevent leaks and wear.

   - Check for Wear and Tear: Regularly inspect the purifier for worn parts, especially if used frequently, to avoid unexpected breakdowns.

Operating a lubricating oil purifier requires attention to detail and adherence to safety procedures. Always consult the specific operating manual for your machine, as different models may have unique features or requirements.
