Autoignition Point Tester For Fire Resistant Oil

    Engineered to comply with DL/T 706‑1999 (Test Protocol for Auto‑Ignition Temperature of Power‑Station Fire‑Resistant Fluid) and align with DL/T 571 power‑sector oil‑testing specifications, the MOEORW‑WER31 measures spontaneous combustion thresholds for phosphate ester‑based fire‑resistant fluids fitted within governing assemblies of generating units rated above 30MW. Test outputs are admissible for power‑plant safety audits and CMA‑accredited third‑party labs.

    Proprietary AI‑driven thermal regulation delivers balanced heat distribution throughout the heating flask; thermal deviation across upper, mid‑ and lower flask zones stays capped at ≤1℃. An integrated viewing mirror lets operators observe flame onset without extra optics. Compact and user‑friendly, this unit serves power‑generation conglomerates, electric‑power research bodies, lubricant fabricators, independent oil‑assay contractors and on‑site power‑O&M enterprises. It accommodates bulk group tenders as well as single‑unit procurement for small maintenance workshops and captive power facilities.

     The intelligent full‑span thermal control system sustains uniform thermal conditions inside the open‑top 200 mL Erlenmeyer flask. Operators draw 0.05 mL fire‑resistant oil aliquot and swiftly inject it into the pre‑heated vessel by means of the high‑precision micro‑syringe, triggering a 60‑second countdown timer.

     When visible flame occurs within 60 seconds, the prevailing flask temperature represents the sample's auto‑ignition value.

In the absence of ignition, raise set‑point temperature by 10℃ and repeat the assay; ensure minimum 15‑minute dwell interval between successive injections.

    Once ignition is captured, incrementally reduce set‑point by 5℃ for iterative retesting until spontaneous combustion no longer occurs. Document the threshold temperature just capable of triggering ignition as the final auto‑ignition result.

     This workflow strictly implements DL/T 706‑1999 requirements, minimizing human‑induced reading scatter for high‑volume specimen batches and satisfying recurring monthly inspection workflows for utility labs and third‑party testing agencies.

On‑site Thermal Calibration & Offset Tuning

Hold down the "Sample Run" icon on the touch panel to enter thermal self‑tuning workspace. Independent correction for upper, middle and bottom temperature readings is supported. Following component wear or hardware swap‑outs, one‑click field calibration eliminates factory‑return downtime and cuts after‑sales service expenditure.

Short‑cut Gradient Temperature Panel

Instant temperature shift presets (+/‑2℃ / +/‑5℃ / +/‑10℃) remove manual numeric input steps, streamlining multi‑step thermal screening workflows for high‑throughput third‑party assay labs.

Single‑Operator Visual Inspection Architecture

Purpose‑built reflector embedded on furnace top removes auxiliary viewing hardware. One technician completes sample injection, timing activation and flame observation solo, cutting labour expenditures.

Modular Flask Swap‑out Assembly

Sensor bracket incorporates limit slide rails plus high‑temperature interlock to prevent improper disassembly. Once adequately cooled, one staff member can complete flask replacement within five minutes in three straightforward steps, without interrupting high‑volume test cycles.

Multi‑Layer Safety Guard Mechanism

- Three‑conductor protective‑earthing power inlet: match industrial socket with live, neutral and protective earth connections. Reliable earthing is mandatory to mitigate electric‑shock hazards for high‑temperature flammable‑sample testing, passing regular power‑supervision safety audits.
- Segmented large‑area heat‑dissipation ducting: dedicated ventilation grilles on side panels prevent overheating under eight‑hour continuous batch‑testing cycles, mitigating high‑temperature scalding risks and accidental ignition of nearby oil‑based materials.
- Mechanical high‑temperature interlock safeguard: limit‑cover slide‑rail for temperature sensor physically blocks flask disassembly while apparatus remains hot, preventing burn‑related incidents.
- Circuit overload cut‑off: embedded overload suppression module avoids nuisance tripping where multiple lab instruments run concurrently. All maintenance must be undertaken by qualified technicians after full power disconnection; internal circuit‑isolation layout mitigates service‑phase hazards.

      ducing staffing requirements. Single‑batch assay turnaround is shortened by approximately 30 %; the instrument supports more than 40 specimen batches daily. Field‑executable one‑click thermal self‑tuning plus independent three‑point correction remove the need for factory return for adjustment, sharply lowering labour and downtime expenses for third‑party laboratories and large‑scale power‑utility operators.

Industrial‑grade comprehensive safety plus one‑stop consumable & after‑sales ecosystem, lowering long‑term group‑procurement maintenance burden Hardware safeguards cover triple‑wire protective earthing, standalone ventilation ductwork, mechanical high‑temperature locking interlock and circuit overload protection, complying with safety‑audit benchmarks for high‑risk power‑lab environments and preventing outages triggered by electric leakage, thermal burns or fire events. Original‑equipment manufacturing delivers the full analyzer plus supporting consumables including Erlenmeyer flasks, K‑type thermocouples and micro‑syringes. Tiered volume‑purchase discounts are available; long‑term consumable‑supply framework contracts can be negotiated. Global 400‑support hotline and regional field‑service engineers serve end‑users. Bulk‑order purchasers may negotiate extended core‑component warranty terms. Multi‑site enterprise clients enjoy localised on‑site support; single‑unit buyers obtain one‑on‑one remote operational coaching.

Product Application

This instrument is designed for power plant laboratories to determine the auto-ignition temperature of fire-resistant fluids used in turbine speed control systems (for 30MW+ generating units). Following the DL/T 706 standard, it injects a 0.05mL oil sample into a heated flask, observes flame occurrence within 1 minute, and records the lowest ignition temperature. The test ensures the thermal safety and reliability of hydraulic fluids in high-temperature turbine operations.
