Power Transformer Oil Open Cup Flash Point Testing Equipment

       The MOEORW‑WES18 automated Cleveland open‑cup flash‑point analyzer delivers standardized open‑cup flash‑point measurement for transformer insulating oil and various petroleum‑based liquids. Also named petroleum flash‑point detector and oil flash‑point analytical unit, this device complies with GB/T 3536‑2008 and GB267‑88 domestic test norms. It integrates Pt‑100 platinum‑resistor temperature sensing with a self‑developed motor‑driven linkage assembly (patent pending) to handle cup lifting, flame triggering, sweeping cycles and post‑test cooling without manual intervention. A colorful touch‑based HMI, built‑in diagnostic suite and local data archiving plus print output streamline lab workflows, while low‑effort upkeep keeps long‑run operational costs under control.

Temperature Acquisition Subsystem Coverage spans 40℃‑400℃, fitted with industrial‑grade platinum resistance probe. Temperature reading error holds within ±1℃; measurement repeatability reaches ±3℃ below 150℃ and ±5℃ for readings above 150℃. Compared against conventional thermocouple hardware, platinum‑resistor sensors generate minimal thermal drift. Stable readouts are maintained across continuous batch runs, cutting re‑test frequency and lowering expenses for consumables and lab manpower.

Main Controller Hardware Built around C8051 high‑speed single‑chip microprocessor. Circuit boards adopt SMT surface‑mount assembly to eliminate quality risks from hand‑soldering such as cold joints or intermittent contact. Extended runtime brings no system lag or temperature offset; lifting mechanism, igniter and air‑cooling module execute synchronized movement with zero perceptible delay.

Automated Actuation Assembly Includes motorized sample‑cup elevation, constant‑speed sweep motion, electric ignition trigger, instant temperature lock upon flash detection with audible‑visual warning, plus automatic air‑cooling cycle once measurement completes. Operators do not need on‑site attendance during full test sequences. Batch sample processing is supported, effectively removing deviation introduced by human manual operation.

Data Output Interface Embedded Chinese‑language thermal printer generates legible, low‑noise hard copies with fast paper feed speed. Serial communication port is reserved for offloading test logs toward external systems, enabling digital filing and satisfying electronic‑record management needs for enterprise laboratories.

Power & Ambient Operating Conditions Maximum power draw ≤700W, compatible with industrial mains AC220±10%V, 50±5%Hz. Acceptable surrounding environment: ambient temperature 5℃‑40℃, relative humidity up to 90%. It performs reliably inside damp chemical workshops and low‑temperature lab environments. Outer dimension: 430×400×260 mm, net weight 24 kg. Compact footprint allows side‑by‑side multi‑unit deployment to expand throughput.

Built‑in Diagnostic Module Seven independent self‑diagnosis channels cover temperature probe, ignition assembly, heating furnace, sweep arm, solenoid valves, cooling blower and printer. Operators launch one‑click system check after power‑on to rapidly pinpoint hardware faults.

Full‑color Touch‑oriented Human‑Machine Interface: Large‑size LCD touch panel features multi‑level Chinese menu layout, separated into four dedicated working screens: system diagnosis, parameter configuration, historical record lookup and real‑time testing. Intuitive navigation lets new personnel get proficient quickly with minimal prior experience.

Highly configurable test setups: Supports two‑digit sample serial numbers (max. value 99). Users can input target flash‑point threshold, adjust ignition duration, apply temperature offset correction, tune heating rate and activate barometric pressure compensation. Auto‑printing can be toggled on or off. Custom parameter profiles for distinct oil mediums may be saved locally to avoid repeated manual configuration for each testing campaign.

Robust record retention capability: All measurement logs persist in local non‑volatile memory permanently. Functions include single‑record printout, serial‑port export and selective single‑entry deletion; bulk one‑shot clearing of historical datasets is available. Meets enterprise traceability and archiving requirements over long operational cycles.

Patent‑pending integrated mechanical linkage: This domestically engineered automatic linkage assembly has filed for national patent protection. Differentiated from entry‑level semi‑automatic competing devices sold on market, it enables unattended continuous measurement and serves as upgraded hardware solution for oil‑testing laboratories across sectors.

Water‑free air‑cooling architecture: Internal forced‑air cooling unit removes necessity for external cooling‑water piping. Laboratory cabling layout gets simplified; equipment‑damage hazards triggered by water leakage are eliminated. No site reconstruction work is required post installation.

Multi‑layer safety safeguard setup: Mechanical hard‑stop limit blocks protect temperature probe and sweep rod against deformation caused by external physical impact. Dual‑ring isolated circuit design prevents short‑circuit risks for flash‑point detector rings and suppresses false flash‑point triggering events. Heating furnace comes with over‑temperature power cut‑off protection to mitigate fire hazards during unattended long‑duration testing.

Maintenance‑friendly construction: Oil residues accumulated on flash‑sensor rings after prolonged service can be wiped away conveniently with petroleum ether. The quantity of wearing spare‑parts is kept small to reduce ongoing maintenance expenditure.
