Automatic Liquid Phase Rust Tester

     The MOEORW‑WER21 Liquid‑Phase Rust Evaluation Instrument assesses rust‑inhibiting performance of additive‑treated mineral oils when blended with water, following the GB/T11143‑2008 national specification. Also known as turbine oil anti‑rust analyzer or mineral‑oil aqueous corrosion tester, this bench‑top device serves lubricant factories, third‑party metrology labs, power utilities and chemical research centers.

The integrated unit merges thermostatic water bath, electronic control cabinet and stirring drive assembly, eliminating extra supporting hardware. Equipped with a 5‑inch multi‑language touch HMI and four isolated test channels, it runs temperature regulation, agitation and timing cycles autonomously. PT100 high‑precision platinum resistance sensors and imported brushless permanent‑magnet drive motors guarantee stable running conditions. Operators may launch four parallel oil‑specimen assessments simultaneously. Collected test logs can be stored for traceability, and generated reports hold legal weight for arbitration scenarios. The hardware delivers steady long‑run performance with minimal failure risk, well‑suited for batch laboratory analysis and routine on‑site oil quality screening.

✅ Full‑standard compliance for arbitration‑valid outputs Thermal structures, stirring mechanics, vessel dimensions and workflow sequences strictly comply with every clause within GB/T11143‑2008. Each instrument completes a 24‑hour simulated rust test prior to shipment, accompanied by factory temperature calibration paperwork and inspection certification. Data outputs can be submitted for product filing and commercial dispute resolution. Many low‑cost copycat units on market show thermal errors above 0.5 ℃ and cannot pass CNAS assessment. Our tight ±0.2 ℃ thermal accuracy plus retrievable calibration logs guarantee audit‑ready traceability.

✅ Quad‑channel isolated layout for boosted lab throughput Four physically separated test stations each feature dedicated stirring drive and independent timing module. Operators may start four distinct oil‑sample runs together or stagger sample loading timelines. Malfunctions affecting one station will not interrupt remaining three channels, so maintenance does not require full‑machine shutdown. Within a standard 24‑hour experimental cycle, one unit handles four batches of specimens, outperforming typical dual‑channel devices and reducing capital expenditure and bench‑space occupation.

✅ Closed‑loop high‑precision thermal control avoids invalid trials PT100 platinum‑resistance detectors pair with SSR non‑contact solid‑state relays for closed‑loop thermal management, removing large temperature swings caused by conventional contactor switching. Thermal subdivision reaches 0.01 ℃; long‑term bath fluctuation remains within ±0.2 ℃, significantly outperforming national‑standard permitted deviation. Built‑in bath offset correction allows on‑site recalibration with reference thermometers without factory return. Every finished unit passes a 72‑hour 0‑100 ℃ burn‑in screening with zero thermal drift, preventing batch‑sample failure and material waste induced by poor temperature stability.

✅ Imported brushless stirring drives: stable rotation & low re‑test expenses All four positions adopt original imported permanent‑magnet brushless motors that generate zero grinding debris to pollute specimens. Under 1000‑hour full‑load running conditions, rotational drift stays below ±10 rpm. Consistent mixing throughout long‑duration 24‑hour tests ensures thorough oil‑water blending, eliminating misjudgments stemming from inadequate stirring and cutting repeat‑test costs. Under normal operating conditions, motor component replacement is unnecessary within three service years.

✅ Intuitive touch‑screen human‑machine interface for quick operator onboarding The 5‑inch high‑definition color touch‑screen initializes automatically upon power‑on. Real‑time bath temperature, set‑point value, per‑channel countdown timers and equipment operational states are displayed straightforwardly. Menu options include temperature setup, timing adjustment, system‑time synchronization, bilingual switching, thermal offset correction and calibration‑record query & export. Factory login password defaults to zero, lowering operational barriers; newly‑assigned lab staff can run complete experiments after brief orientation. Archived calibration entries satisfy mandatory data‑retention rules during laboratory audits.

✅ Multi‑layer hardware safety safeguards against lab hazards Mandatory water‑level guidance: users must fill clean water to 3‑4 cm below tank rim before starting experiments. Dry‑run situations trigger automatic heating‑module cut‑off for fire prevention. Replaceable onboard fuses plus spare fuses delivered with unit resolve circuit faults on‑site without sending hardware back to manufacturer. Three‑core fully‑grounded power cord mitigates electric‑shock danger within water‑bath surroundings. Anti‑overflow bath geometry reserves safe liquid height and protects internal electronics from overflow‑triggered short‑circuits.

✅ Industrial‑grade component selection curbing after‑sales workload Key thermal‑control, stirring and touch‑screen assemblies adopt industrial‑spec components. Every main‑board semi‑finished product undergoes 24‑hour powered aging. Final goods pass triple‑stage factory checks: temperature‑accuracy validation, stirring‑speed verification and insulation‑safety inspection. Factory defect‑rate is controlled below 0.3 %. Common issues including thermal offset and blown fuses can be rectified on‑location, cutting logistics‑related maintenance expenditure.
