A vacuum degasser is used to remove gas from drilling fluid, helping restore mud density, stabilize performance, and support mud circulation purification systems. Proper maintenance is essential for reliable operation and longer equipment life.
 

 
Daily Operation and Monitoring

Regularly check the vacuum gauge and adjust the pressure-reducing valve to maintain a vacuum degree of 0.03–0.05. Before entering gas-bearing formations, ensure the vacuum degasser is operating correctly.
 
Post-Use Cleaning

After use, clean the rotor and suction pipe inside the vacuum tank. Disconnect the power, remove inspection covers, check for damage, clear debris, and wash the tank wall and rotor with a high-pressure water hose.
 
Weekly Top Cover Cleaning

Clean the vacuum tank top cover weekly to prevent blockage of the gas channel. Flush the gas collection chamber, foam separator, vacuum line, wire plug, and gauge base with clean water or a high-pressure hose for 3–5 minutes. Clean after each drilling operation for best performance.
 
Monthly Lubrication

Add 250–300 mL of grease to the main shaft bearing every month to reduce wear and extend service life.
 
Vacuum Pump Maintenance

Inspect bearings and lubrication regularly. Bearing temperature should stay 15–20°C above ambient temperature. If it exceeds 30°C, monitor the vacuum gauge, replace separator water when necessary, and keep water temperature below 35°C.
 
Winter Precautions

Drain water from the separator and pump immediately after use to prevent freezing damage. After repairs or reinstallation, ensure proper coupling alignment to avoid premature pump failure.
 
Conclusion

Regular monitoring, cleaning, lubrication, vacuum pump maintenance, and winter protection will help maximize the service life of your vacuum degasser and maintain reliable drilling performance.
