Maintenance and Care Suggestions

To extend the service life of spare parts and ensure the stable operation of ZL240 series vacuum pumps, our engineers with 28+ years of on-site oilfield maintenance experience provide practical tips (with avoidable pitfalls):

• Bearings & Rotating Parts: Check W21156213 Bearing 6213-2RS and X06020005 Vacuum pump shaft every 80 working hours for temperature, noise, and wear; replace if temperature exceeds 85°C, abnormal noise occurs, or wear exceeds 0.1mm. Add lithium-based lubricating grease every 120 working hours to ensure smooth operation—insufficient lubrication can shorten bearing service life by 3,200 hours. Avoid over-tightening the bearing cap, as this can cause bearing jamming.

• Seals & Gaskets: Inspect W12124653 Oil seal FB65×90×12, W11214508 O-ring 450×7, and X06020007 Paper pad φ120×φ160 every 70 working hours for cracks and leakage; replace if cracks are found or leakage occurs. Clean the seal contact surface before installation—oil or debris on the surface can cause seal failure. Avoid using sharp tools when installing seals, as this can damage the seal lip.

• Structural Components: Check X06020002 Vacuum pump housing and X06020003 Vacuum pump cover every 100 working hours for deformation and corrosion; replace if deformation exceeds 0.3mm or corrosion is severe. Clean the pump cavity regularly to remove oil sludge and debris—blockages can increase pump load and cause component wear.

• Fasteners & Connecting Fittings: Check W01042081 Bolt M8×25, W01042125 Bolt M12×45, and W41302110 Rc2″ tapered union every 90 working hours for tightness and wear; replace if thread damage or wear is found. Always use matching spring washers and flat washers—non-standard washers reduce fastening force and cause air leakage.

• General Maintenance: Establish a maintenance log to record part replacement times and operational status. Follow API 682 (4th edition) and relevant national standards (GB/T5783-2000, GB/T9877.1-1988) for regular equipment inspection, and use only matching ZL240 series spare parts to avoid system damage caused by mismatched components. Store spare parts in a dry, clean environment to prevent oil contamination and corrosion.
