Overview
The HK-3130KQ Air Release Value Tester is an automated benchtop instrument engineered for the quantitative determination of air release characteristics in high-performance industrial lubricants—including phosphate ester-based anti-wear turbine oils, hydraulic fluids, and steam turbine oils. It operates on the principle defined in ASTM D3427 and aligned with GB/T 1884–1992 and SH/T 0308–1992, measuring the time required for entrained air to separate from a heated oil sample under controlled gas flow and temperature conditions. The system employs a precision water bath for thermal stabilization of the test vessel, coupled with integrated compressed air delivery at regulated pressure (19.6 kPa), enabling reproducible simulation of real-world fluid aeration and deaeration dynamics in power generation and heavy machinery systems.
Key Features
- Automated test sequence with programmable start/stop, eliminating manual timing and operator variability.
- Integrated water bath heating system with PID-controlled temperature regulation (ambient to 100 °C) and ±0.3 °C stability—critical for compliance with standardized test protocols.
- Dedicated air supply module delivering consistent 0.2 kgf/cm² (19.6 kPa) pressure; air temperature maintained within ±3 °C tolerance during test execution.
- Backlit graphical LCD interface with bilingual operational prompts (English firmware available upon request); built-in non-volatile real-time clock ensures audit-ready timestamping of all test logs.
- Compact footprint (480 × 320 × 520 mm) and low power draw (≤800 W) enable deployment in QC labs, maintenance workshops, or mobile field testing units without dedicated HVAC or high-capacity circuits.
- Robust mechanical architecture featuring corrosion-resistant stainless steel bath housing and sealed pneumatic pathways to ensure long-term reliability in industrial environments.
Sample Compatibility & Compliance
The HK-3130KQ is validated for use with mineral-based, synthetic hydrocarbon, and phosphate ester turbine oils (e.g., Fire-Resistant Fluids per ASTM D2883), as well as aviation hydraulic fluids meeting MIL-PRF-5606 and MIL-PRF-83282 specifications. Its measurement methodology satisfies the requirements of GB/T 1884–1992 (Petroleum Products—Determination of Density—Hydrometer Method, adapted for air release context), SH/T 0308–1992 (Method for Determination of Air Release Value of Turbine Oil), and technical equivalency to ASTM D3427–2021. The instrument supports GLP-compliant operation when paired with external data logging software that provides electronic signatures, audit trails, and 21 CFR Part 11–ready metadata tagging.
Software & Data Management
While the HK-3130KQ operates as a standalone unit with local display and internal storage of up to 100 test records, it features an RS-232 serial interface (standard) for bidirectional communication with laboratory information management systems (LIMS) or custom QA databases. Exported data includes test ID, sample ID, start/end timestamps, bath temperature profile, air pressure confirmation, and final air release time (in minutes:seconds format). Firmware supports UTC-synchronized time stamping and user-defined calibration offset application—enabling traceability to NIST-traceable reference standards. Optional PC-based companion software (sold separately) provides statistical process control (SPC) charting, batch trend analysis, and PDF report generation compliant with ISO/IEC 17025 documentation requirements.
Applications
- Pre-commissioning verification of turbine oil cleanliness and air-handling performance prior to generator startup.
- Routine in-service monitoring of hydraulic fluid degradation in hydroelectric and nuclear plant control systems.
- Quality conformance testing for OEM-supplied fire-resistant fluids used in aviation and marine propulsion hydraulics.
- Root-cause analysis of foaming, cavitation, or pump inefficiency linked to excessive air retention in circulating lubrication systems.
- Supporting predictive maintenance programs by trending air release time against oxidation markers (e.g., RPVOT, FTIR carbonyl index) and particle count data.
FAQ
What standards does the HK-3130KQ comply with?
It is designed to meet GB/T 1884–1992, SH/T 0308–1992, and is functionally equivalent to ASTM D3427 for air release value determination.
Does the instrument require external compressed air?
No—it integrates a regulated internal air supply set to 0.2 kgf/cm² (19.6 kPa); no external compressor or regulator is needed.
Can test results be exported to LIMS?
Yes, via RS-232 serial output with ASCII-formatted data packets compatible with most LIMS and SCADA platforms.
Is calibration traceable to national standards?
Temperature sensors are factory-calibrated against NIST-traceable references; users may apply certified offsets via the configuration menu.
What maintenance is required for long-term accuracy?
Annual verification of bath temperature uniformity and air pressure delivery is recommended; full service includes sensor recalibration and seal replacement per manufacturer’s preventive maintenance schedule.
