High temperature and low temperature low outline tester tester is widely used in aviation, aerospace, defense, electrical, electronics and other products and machine parts high temperature and humidity test at atmospheric pressure. For users of the machine (or parts), electrical appliances, equipment, materials, coatings, coating, etc. for an aging test in order to test the performance and quality of reviews, this device has the following basic characteristics: 1, the test system design advanced and reasonable structure, manufacturing process specifications, good looks, generous, easy maintenance. 2, the supporting parts and assembly matching good, the main function of components are imported parts with the international advanced level. 3, to improve the product's safety and reliability, to ensure that the user for a long time, the requirements of stable operation. 4, the device easy to use, the buyer need to provide electricity and to meet the requirements of the work environment can be. Low temperature tester main technical indicators: l Studio Size: Selection 2 Dimensions: 3 Temperature selection can range: -40 ~ 150 ℃ 4 Temperature fluctuation: ± 0.5 ℃ 5 temperature uniformity: ≤ ± 2 ℃: 6 heating time: 0 ~ + 150 ℃ 70min 7 Cooling Q: 20 ~ -0 ℃ 20mln 8 Power: 220V50Hz 9 Winds: ≤1.7m / s; 10 power: 4KW above products run technical data are at room temperature 25 ℃, relative humidity ≤85% RH, chamber load, atmospheric conditions, temperature constant measured after two hours. Low temperature refrigeration parts tester 1) refrigeration compressors: The world known brand names in France 'Taikang "closed compressor single-stage refrigeration system of this type compressor cooling capacity, low noise, low power consumption, high efficiency can. long-term, stable and reliable operation, the system as a whole constitute a reasonable, cost-run 2) Evaporator: Fin Evaporator uses 30% higher than the average evaporator heat transfer efficiency, a handsome, compact, and quick cooling 3. ) high efficiency condensing evaporator heat exchanger consists of a number of adult-shaped corrugated sheet suppress corrosion-resistant stainless steel flakes, opposite an adjacent pair of stainless steel sheet corrugation direction, corrugated back line intersect each other constitute a large number of contact pads, mountains in the complex intersecting the contact network channels so that both sides forming fluid turbulence, improve heat transfer intensity, while strong turbulence and smooth stainless steel surface in the surface difficult to scale the flow path brazed plate heat exchange, the use of this heat exchanger after not only can reduce system resistance, but also to overcome the past made large-scale cryogenic chamber dimensions of this part of the large, poor heat transfer, low efficiency 4) refrigeration parts: solenoid valve (Japan Saginomiya and Italy Casto), Manual As of Min (Italy Casto), filter (Danfoss and American Sporlan) are imported brand-name products; 5) Evaporator equipment used by the US, one-sided welding, cold-expanded; 3 Cooling: air-cooled; 4 Cooling agent: American authentic Honeywell.Genetrom.R404 (environmentally friendly fluorine lithium Aung) 5 humidification way: shallow tray evaporative humidifier; water supply device 6: Using automatic water supply systems, water without water humidifying water with alarm device 7: distilled or deionized water to high temperature and low tester air conditioning; 1, the air conditioning mode: Forced ventilation circulation, balance thermostat law that when the target temperature requirements are higher than room temperature +15, the cooling system is not working, the central control. amplification system based on the collected inside temperature signal, analog / digital conversion, after the non-linear calibration and temperature setpoint (target) for comparison, the error signal obtained by the PID operation, automatic control of heating output regulation signal the output power, the test tank heating and hot bulk to achieve a dynamic equilibrium, and ultimately achieve the purpose of constant temperature. When the target temperature requirements below room temperature +15, the refrigeration system in the case of continuous operation, the central control system amplified according to the collected inside temperature signal, analog / digital conversion, after the non-linear calibration and temperature setpoint (target) for comparison, the error signal obtained by the PID operation adjustment signal output, automatic control of heating output power, and finally to achieve a dynamic equilibrium temperature inside 2, air circulation device: built air-conditioned rooms, circulation air duct and centrifugal fans: 3, air heating: quality nickel-chromium alloy electric heater; 4. Air cooling: the multi-stage diaphragm air heat exchanger (Evaporator) low temperature refrigeration system tester: 1 exquisite workmanship of the low-temperature process: low temperature coupled with high-quality oxygen-free copper pipe conduit, nitrogen welding, high packing leak-proof technology to ensure the quality of welding; pipe length, inclination, the slope and to undergo a rigorous calculation, in order to achieve the best cooling effect: threaded connections used by the US "Loctite" anaerobic adhesive seal, basic stamp made cryogenic Freon leak test equipment and so on. Low temperature tester chamber structure: a chamber with the overall structure, electrical control system operation and easy maintenance. Chamber adopts SUS304 stainless steel plate inner walls, outer box made of high quality cold-rolled steel molding, surface acid phosphate processing made after electrostatic spray treatment; 2 chamber door: the use of flexible silicone rubber suspension tambour plus dense silicon strip good sealing performance of the device for easy adjustment. In order to prevent condensation at low temperature test door edge and the door or frost, door frames and door edge is provided with an electric defroster. To facilitate the observation of the sample with the cabinet door 265 × 375 electric heating frost hollow glass; 3 fine glass fiber insulation materials, thermal insulation effect is good, the appearance of the chamber without frost, no condensation. 4 Box side opened a 050 test holes. 5 water tank: Front, add water more convenient 6 studio lighting: 7w energy saving lamps. Low temperature tester and Control System: 1 temperature components: Import PTl00 Central American precision platinum resistance temperature controller 2: Using self-developed Chinese RUIKOYOM displayed temperature program control regulator, the controller uses LCD touch screen liquid products, control The system uses human-computer dialogue; with automatic, intelligent, user-friendly design. It can display, set test parameters, the program curve, working hours, heating systems, refrigeration units, circulating fan working condition. Both test runs automatically and PID parameter self-tuning function; can be automatically combined heating system, cooling system, circulating fan, over-temperature alarm and other subsystems work to ensure high quality control over the entire temperature control system; control system further includes a self-test self-diagnostic function, automatic fault display, alarm.
