Chongqing Chinon Oil Filtration Machine: On-Site Maintenance & Field Application Case in 2026
Chongqing Chinon (Chinon Filtration) — with 30+ years of industrial oil purification expertise — delivers robust, CE/ISO-certified oil treatment solutions for power generation, petrochemical, and heavy industry. Below are 5 key on-site maintenance & filtration projects executed in 2026, showcasing real-world performance across UHV transformers, 600MW turbines, lubricant plants, and refineries.
1. 800kV UHV Transformer: Online Transformer Oil Filtration (Double-Stage Vacuum)
- Client: State Grid UHV Substation
- Equipment: Chinon ZJA-12000 Double-Stage High-Vacuum Oil Purifier (12,000L/h)
- Challenge: 800kV transformer in service; online oil purification required to remove moisture (<5ppm), dissolved gases, and carbon particles without shutdown
- Result: Oil breakdown voltage restored to ≥70kV; NAS cleanliness improved to Grade 5
2. 600MW Steam Turbine Unit: Electrostatic Oil Filtration (Lubricating Oil)
- Client: Datang Power Generation Plant
- Equipment: Chinon ESP-300 Electrostatic Oil Purifier (3,000L/h)
- Challenge: Turbine lube oil contaminated with sub-micron varnish, sludge, and metal wear particles; risk of bearing failure
- Technology: Electrostatic adsorption removes 0.1~5μm contaminants without filter consumables
3. Shell Lubricants: 30m³/h Lubricant Purification & Dehydration Site
- Client: Shell Global Lubricants Blending Plant
- Equipment: Chinon TY-30000 Vacuum Lubricating Oil Purifier (30,000L/h = 30m³/h)
- Scope: Bulk purification of Shell Hydraulic Oil (Tellus 68) & Gear Oil (Omala 320); dehydration, degassing, and fine filtration
- Standards met: Moisture ≤5ppm, gas content ≤0.1%, NAS ≤4
4. Sinopec: Insulating Oil Treatment & Reclamation Site
- Client: Sinopec Lubricant Company (Jingmen Plant)
- Equipment: Chinon ZYD-2000 Transformer Oil Regeneration System (20,000L/h)q
- Mission: Reclaim aged/oxidized insulating oil from power transformers; remove acid, sludge, and deep oxidation byproducts
- Result: Waste oil restored to new-oil specs; saved ~80% vs. oil replacement
5. Datang International: 12,000L/h Transformer Oil Filter (UHV Treatment Site)
- Client: Datang International Power
- Equipment: Chinon ZJA-12000 Double-Stage Vacuum Oil Purifier (12,000L/h)
- Application: Offline filtration + vacuum drying for new 500kV/800kV transformers before commissioning
- Capacity: Processes 12,000 liters per hour; ultimate vacuum ≤5Pa
