Oxidation Stability Tester

MOEORW-WET72 Oxidation Stability Tester, also named Rotating Bomb Tester, Lubricant Oxidation Stability Measuring Instrument, Oxygen Bomb Oxidation Tester, fully complies with domestic petrochemical industry standard SH/T0193 (Standard Test Method for Oxidation Stability of Lubricating Oils by Rotating Bomb Method) and ASTM D 2272-2011 Method B Metal Bath Rotating Bomb, and supports international standards ASTM D4742 and IP229 simultaneously. The equipment adopts a dual-channel independent metal bath oxygen bomb structure with two standard temperature control points: 140℃ and 150℃. The 150℃ mode evaluates oxidation stability of new & used turbine oils and automotive engine lubricants; the 140℃ mode rapidly tests mineral insulating oils with phenolic antioxidants. It is not applicable to antioxidant-containing mineral insulating oils whose kinematic viscosity exceeds 12mm²/s at 40℃. The test data is authoritative and credible for issuing standard inspection reports. We supply oil manufacturers, power plants, third-party testing laboratories, university research institutes and instrument distributors, supporting both single-unit retail and bulk group procurement.

Advantage 1 Dry Metal Bath
Abandon traditional oil bath heat conduction structure, adopt integrated alloy metal constant temperature bath, exclusive structure for SH/T0193 Standard Method B Metal Bath. Every unit undergoes 48-hour non-stop high-temperature aging test before delivery, with zero medium volatilization, leakage or pungent odor. Factory air tightness test standard: empty bomb pressurized to 700KPa, kept at 150℃ for 1 hour without pressure drop; qualified only if pressure drop ≤7KPa within 5 minutes. Benefits for bulk buyers: No continuous purchase of heat conduction oil, cutting 60% of consumable and labor maintenance cost; eliminate fire hazard and waste gas pollution from heat transfer oil, easily pass enterprise safety & environmental assessment. Compact desktop design saves lab space for bulk layout and lab expansion projects. Benefits for single-unit buyers: No regular replacement of heat transfer medium, no oil fume pollution, minimum daily maintenance workload for small single-person labs.
 

Advantage 2 Full-process Automatic Intelligent Control System
Integrate automatic constant temperature, automatic oxygen filling, real-time pressure-time curve recording, automatic oxidation inflection point identification, automatic heating cut-off after test completion and automatic data storage. The touch screen contains 5 functional pages: main interface, oxygen filling interface, parameter setting, system calibration and historical data query, supporting sample number input, temperature & pressure calibration and stirring motor self-inspection. Benefits for bulk buyers: No full-time operator required for mass samples, one inspector can manage multiple units to reduce labor cost. Automatic data archiving avoids manual recording errors, test reports comply with supervision standards. Historical data of Channel A/B can be switched with one click for long-term sample traceability. Benefits for single-unit buyers: Equipped with 7-step simplified operation procedure; operators without professional background can run the equipment independently after short training, no professional lubricant testing engineer required.
 

Advantage 3 Multi-layer Safety Protection System, Qualified for Enterprise Bulk Safety Assessment
1.Sealing Protection: Three-point evenly tightened nuts for oxygen bomb chamber, equipped with thick tear-resistant silicone sealing gaskets. Every unit passes air tightness pressure test before delivery to prevent high-pressure leakage.
2.High-temperature Protection: Thickened heat insulation cover for the whole machine. System forces users to cool down below 40℃ before pressure relief after test to avoid injury from high temperature and high pressure.
3.Pressure Early Warning: Real-time pressure monitoring during oxygen filling, pop-up reminder for excessive pressure drop to quickly locate leakage points and prevent high-pressure safety accidents.
 

Advantage 4 Modular Split Structure, Lower Long-term Maintenance Cost
Temperature control, pressure sensor and stirring motor of Channel A & B are fully independent modular components. Fault of one component will not block the operation of another channel. The manual contains complete fault comparison table; lab staff can troubleshoot basic faults of power supply, motor and heating tube by themselves. Standardized universal core spare parts with tiered wholesale price for bulk machine orders, greatly reducing long-term maintenance expenditure.

This Rotating Bomb Tester (Lubricant Oxidation Stability Measuring Instrument, Oxygen Bomb Oxidation Tester) is applicable to oxidation stability test of all types of oil products, matching all categories of purchasers precisely:
1.Lubricant Manufacturers: Factory quality inspection of industrial lubricants, turbine oils and automotive engine oils; bulk procurement for labs supporting production lines.
2.Power Grid & Thermal Power Plants: Periodic performance test of transformer mineral insulating oil, stable repeat bulk orders from state-owned power enterprises.
3.Third-party Oil Testing Laboratories: Entrusted test of in-service lubricants, waste industrial oil and antioxidant additives; multiple units purchased in parallel to raise daily test capacity.
4.Universities & Quality Inspection Research Institutes: R&D of oil antioxidants and teaching experiments for industrial standards, support single-unit purchase and bulk procurement for lab projects.
5.Instrument Distributors: Supply standardized complete machines and full set of consumables in packages, support customized enterprise LOGO and Chinese-English bilingual interface for domestic wholesale and export orders.

• Equipment Connection: Connect instrument air inlet to oxygen cylinder via PU tube, reliably ground the power cord.
• Parameter Setting: Enter parameter setting page on touch screen, input sample ID, set 150℃ for turbine oil and 140℃ for insulating oil.
• Sample Loading: Put catalyst coil into sample cup, accurately weigh 50±0.5g oil sample and add 5mL distilled water; pour another 5mL distilled water into oxygen bomb chamber. Place sample cup steadily, evenly tighten three nuts for sealing and close bath needle valve.
• Oxygen Replacement & Filling: Switch to oxygen filling page, fill Channel A/B to 620KPa then release pressure slowly, repeat replacement twice. Lock valve after third filling to 620KPa, keep static for 5 minutes for air tightness test, qualified if pressure drop ≤7KPa.
• Start Test: Cover heat insulation shield, tap Channel A/B to start test. The machine will heat, rotate, record pressure curve and judge oxidation inflection point automatically.
• Post-test Handling: Machine stops automatically after test. Release pressure only after temperature drops below 40℃, disassemble oxygen bomb and clean all spare parts for next use.
