• What should we pay attention to when using a thermal shock test chamber (water-cooled)?

  Nov 22, 2025

  I. Before Operation Use deionized water or distilled water as cooling water (to prevent scale formation); control temperature at 15-30℃, pressure at 0.15-0.3MPa, flow rate ≥5L/min. Clean the Y-type filter element in advance to ensure unobstructed water flow. Inspect water supply/drainage pipelines for secure connections, no leakage or kinking; keep drainage ports unobstructed with a height difference ≥10cm. Ensure the environment is ventilated and dry, grounding resistance ≤4Ω, and power supply (AC380V±10%) stable. Keep the inner chamber and shelves clean. Sample volume ≤1/3 of effective capacity, with weight evenly distributed on shelves. Seal moisture-sensitive parts of non-hermetic samples to avoid condensation affecting test accuracy. II. During Operation Real-time monitor cooling water pressure, flow rate and temperature. Immediately shut down for troubleshooting (pipeline blockage, leakage or chiller failure) if pressure drops sharply, flow is insufficient or temperature exceeds 35℃. Set high/low temperature parameters per GB/T, IEC and other standards (not exceeding rated range); control heating/cooling rate ≤5℃/min. Prohibit instantaneous switching between extreme temperatures. Do not open the door arbitrarily during operation (to prevent scalding/frostbite from hot/cold air). Use protective gloves for emergency sample handling. Shut down immediately for maintenance upon alarm (overtemperature, water shortage, etc.); prohibit forced operation. III. After Test Turn off power and cooling water inlet/outlet valves; drain residual water in pipelines. Clean the water tank and replace water monthly; add special water stabilizer to extend pipeline service life. Wipe the inner chamber and shelves after temperature returns to room temperature. Clean the air filter (1-2 times monthly); inspect pipeline seals and replace aging/leaking ones promptly. For long-term non-use: Power on and run for 30 minutes monthly (including water cooling system circulation), inject anti-rust protection fluid into pipelines, and cover the equipment with a dust cover in a dry, ventilated place. IV. Prohibitions Prohibit using unqualified water (tap water, well water, etc.) or blocking filters/drainage ports (to avoid affecting heat dissipation). Prohibit overloading samples or unauthorized disassembly/modification of water cooling pipelines/core components. Repairs must be performed by professionals. Prohibit frequent start-stop (wait ≥5 minutes after shutdown before restarting). Prohibit placing flammable, explosive or corrosive substances.

• Industrial Precision Ovens: The Key to Precise Temperature Control

  Nov 21, 2025

  In modern industrial manufacturing, industrial precision ovens are key "temperature artisans". They are widely used in electronics, aerospace, automotive, medical and other fields, providing stable performance and reliable quality for products. Gaining an in-depth understanding of their principles not only clarifies the scientific logic of industrial production, but also helps practitioners use equipment efficiently to improve benefits. (I) Heating System: The Source of Heat The heating system is the "heat source core" of the oven. The thermostat controls the thyristor through signals to adjust the heater power and regulate heat output: full power is supplied when the temperature is much lower than the set value, power gradually decreases when approaching the set value, and output stops when the set value is reached. This is energy-efficient and achieves high temperature control precision. (II) Air Circulation System: The Messenger of Heat Transfer Composed of a blower motor, extended shaft and multi-wing fan blades, the air circulation system is critical for heat transfer. The motor drives the wind wheel to rotate and form air flow, which is evenly delivered to all areas of the oven through optimized air ducts, avoiding dead corners and temperature differences. Hot air fully contacts materials during circulation to achieve rapid and uniform heating, which is essential for high-precision processes such as electronic chips and optical lenses. (III) Electrical Control System: The Core of Precise Operation The electrical control system is the core control unit of the oven. The Q8 series electrical control system adopts full-touch operation with a control precision of 0.01 level and supports multiple sensor adaptations. It has 100 built-in processes (50 steps per group), including EVT, cold output and transmission output functions. The DO channel features safe isolation and arc suppression design, enabling convenient, accurate and reliable operation that adapts to diverse control scenarios. Future Outlook: Technological Innovation Leads Development In the future, industrial precision ovens will focus on three major innovation directions: intelligence, energy conservation and environmental protection, and special process adaptation, continuously innovating to shape a new industrial future.

• Sample Restrictions for All Models of Test Chambers

  Nov 17, 2025

      As core equipment in industrial production and scientific research that accurately simulates complex environmental conditions such as high and low temperatures, and humidity, the safe and stable operation of test chambers not only directly affects the test process, but is also closely related to the characteristics of test samples. To maximize the protection of the performance of the equipment's core components, avoid safety risks during operation, and ensure the accuracy and reliability of the final test data, all models of test chambers have established clear and strict restriction standards for sample selection. Testing and storage of the following models of samples are strictly prohibited. The specific prohibited scope includes: • Flammable substances such as gasoline and ethanol, explosive substances such as gunpowder and acetylene, and volatile substances such as methanol and ether; • Corrosive substances such as strong acids, strong alkalis and various corrosive solvents that may damage the equipment cavity; • Biological samples such as microorganisms, cell tissues and living organisms that may cause pollution or safety hazards; • Samples that are strong electromagnetic emission sources such as high-frequency emission modules, which may interfere with the equipment's control system; • Radioactive substances with radiation hazards such as uranium and cobalt; • Highly toxic substances that pose serious hazards to humans and the environment, such as cyanides and highly toxic pesticides; • All models of samples that may generate flammable, explosive, volatile, highly toxic, corrosive, or radioactive substances due to changes in temperature and humidity during the testing or storage process.     Before starting the test chamber, operators must confirm the specific properties of the samples through professional testing methods or authoritative materials, and strictly abide by the above restriction requirements. If there is any doubt in judging the applicability of the samples, they should consult the technical personnel of the equipment manufacturer or experts in related fields immediately, and must not operate blindly based on experience. This is to avoid equipment cavity damage, control system failure, safety accidents, or serious deviations in test data caused by illegal use.

• User Preparation Before Delivery of High and Low Temperature (Humidity) Test Chamber

  Nov 15, 2025

  1. Preparation for Load-bearing and Dimensional Adaptation • The load-bearing capacity of the site floor shall strictly meet the core requirement of ≥500kg/m², which is a key prerequisite for ensuring the long-term stable operation of the equipment and avoiding equipment deformation or safety hazards caused by insufficient load-bearing capacity. • It is necessary to accurately confirm the external dimensions of the test chamber specified in the technical specification in advance. Combined with the on-site actual survey of the transportation and installation path, ensure that the equipment can smoothly pass through all key passage nodes such as elevators, laboratory doors and corridors, so as to avoid delay in delivery and installation due to inconsistent dimensions. 2. Preparation for Installation Site Conditions • The floor of the installation site shall be flat without protrusions and depressions, and the ventilation conditions shall meet the basic standards for equipment operation. At the same time, there shall be no flammable, explosive, corrosive gases or dust in the environment, as such substances will seriously affect the service life of equipment components and the accuracy of test data. • Strong electromagnetic radiation sources such as high-voltage lines and large motors should be actively avoided near the equipment installation location, as strong electromagnetic interference may cause disorder of the equipment control system, thereby affecting the temperature and humidity control accuracy of the test chamber. • A floor drain that meets the drainage standards must be provided within 2 meters of the equipment's refrigeration unit. This requirement is to timely discharge the condensed water generated during the operation of the refrigeration system, so as to avoid water accumulation soaking the equipment or polluting the site environment. • Sufficient maintenance and operation space shall be reserved around the equipment in accordance with specifications. The specific requirements strictly follow the following standards: Area A ≥80cm, Area B ≥60cm, Area C ≥110cm, Area D ≥110cm. Sufficient space is a necessary guarantee for later equipment maintenance, calibration and component replacement.

• Differences between High and Low Temperature Test Chamber and Constant Temperature Test Chamber

  Nov 13, 2025

      In environmental reliability testing, high-low temperature humidity test chambers and constant temperature and humidity test chambers are easily confused due to similar names, but they differ significantly in testing capabilities, applications and technical characteristics. Accurate distinction and selection are key to ensuring valid test data. This blog will analyze the core differences and provide selection suggestions. I. Core Definition: Essential Distinction of Functional Boundaries     The core difference between the two starts with functional positioning, which directly determines the applicable scenarios.     The core of the constant temperature and humidity test chamber is "maintaining stability". It can accurately control and maintain the set temperature and humidity for a long time, and is used to simulate the long-term performance of products in specific environments, such as electronic component stability testing and textile temperature-humidity sensitivity testing. Its core requirement is "steady-state environmental performance verification".     The high-low temperature humidity test chamber focuses on "dynamic simulation". In addition to precise temperature and humidity control, it has a wide-range fluctuation capability, which can simulate environments such as high-low temperature cycles and alternating humidity and heat, such as extreme temperature differences during product transportation and diurnal temperature-humidity changes of outdoor equipment. Its core requirement is "dynamic environmental reliability verification". II. Key Differences: Multi-dimensional Analysis from Technology to Application 1. Temperature and Humidity Range and Fluctuation Capacity     The constant temperature and humidity chamber has a mild temperature and humidity range (temperature 0℃-100℃, humidity 30%-95%RH) and high control precision (temperature fluctuation ±0.5℃, humidity ±2%RH), but no extreme temperature-humidity impact capability.     The high-low temperature humidity chamber has a wider temperature and humidity coverage (temperature -70℃~200℃, humidity 10%-98%RH) and rapid change capability (heating rate 3℃/min-15℃/min, cooling rate 1℃/min-10℃/min), which can realize rapid cycle switching between "high temperature and high humidity - low temperature and low humidity"—a feature unavailable in the former. 2. Differences in Core Technical Architecture     The constant temperature and humidity chamber adopts single-stage compression refrigeration, conventional resistance heating, and steam or ultrasonic humidification. Its system design focuses on "energy saving and stability", with simple structure and low operating cost.     To meet extreme needs, the high-low temperature humidity chamber uses cascade refrigeration, rapid-heating tubes, and its humidity system includes a fast-response dehumidification module, with a thicker insulation layer on the chamber wall. Its technical complexity and manufacturing cost are much higher than the former. 3. Applicable Scenarios and Testing Purposes     The constant temperature and humidity chamber is used for steady-state environmental adaptability testing, such as electronic component aging and pharmaceutical storage simulation, to verify the performance consistency and durability of products in a fixed environment.     The high-low temperature humidity chamber focuses on dynamic reliability testing, such as high-low temperature cycling of auto parts and extreme environment simulation of aerospace products, to expose product defects (material aging, structural deformation, etc.) under drastic environmental changes.     In summary, the constant temperature and humidity chamber guards the steady-state environment, while the high-low temperature humidity chamber challenges the dynamic environment. There is no absolute advantage or disadvantage between the two. Only by matching needs, clarifying scenarios and budgets can the test truly guarantee product quality.

• Was soll ich tun, wenn die Hoch- und Niedertemperaturprüfkammer Probleme hat?

  Jun 23, 2025

  Hoch- und Niedertemperaturprüfkammer Bei der Verwendung können verschiedene Probleme auftreten. Nachfolgend finden Sie eine Zusammenfassung möglicher Fehler und ihrer Ursachen aus verschiedenen Perspektiven:1. KernsystemfehlerTemperatur außer KontrolleGrund: Die PID-Regelparameter sind nicht im Gleichgewicht, die Umgebungstemperatur überschreitet den Auslegungsbereich des Geräts, Temperaturstörungen in mehreren Zonen.Fall: In einer Werkstatt mit Sonderumgebung kommt es aufgrund der hohen Außentemperatur zu einer Überlastung des Kühlsystems, was zu einer Temperaturdrift führt.Die Luftfeuchtigkeit ist anormalGrund: Eine schlechte Wasserqualität bei der Befeuchtung führt zu Kalkablagerungen und Düsenverstopfungen, zum Ausfall der piezoelektrischen Platte des Ultraschallbefeuchters und zu einer unvollständigen Regeneration des Entfeuchtungs-Trockenmittels.Besonderes Phänomen: Beim Test mit hoher Luftfeuchtigkeit kommt es zu einer Rückkondensation, die dazu führt, dass die tatsächliche Luftfeuchtigkeit in der Box niedriger ist als der eingestellte Wert.2. Mechanische und strukturelle ProblemeDer Luftstrom ist ungeordnetLeistung: Im Probenbereich herrscht ein Temperaturgradient von über 3 °C.Grundursache: Das kundenspezifische Probengestell veränderte den ursprünglich konzipierten Luftkanal und die Ansammlung von Schmutz auf den Radialventilatorflügeln führte zur Zerstörung des dynamischen Gleichgewichts. DichtungsfehlerNeuer Fehler: Die Magnetkraft der elektromagnetischen Türdichtung lässt bei niedrigen Temperaturen nach und der Silikon-Dichtungsstreifen wird nach -70 °C spröde und reißt.3. Elektrik und SteuerungIntelligenter SteuerungsfehlerSoftwareebene: Nach dem Firmware-Upgrade tritt ein Fehler bei der Einstellung der Temperatur-Totzone auf und der Überlauf der historischen Daten führt zum Absturz des Programms.Hardwareebene: Ein Ausfall des Halbleiterrelais SSR führt zu kontinuierlicher Erwärmung und die Buskommunikation ist elektromagnetischen Störungen durch den Wechselrichter ausgesetzt.SicherheitslückenVersteckte Gefahren: der synchrone Ausfall des dreifachen Temperaturschutzrelais und der Fehlalarm durch den Ablauf der Kalibrierung des Kältemitteldetektors.4. Herausforderungen besonderer ArbeitsbedingungenSpezifischer TemperaturschockProblem: Bei einer Umwandlung von -40 °C auf +150 °C kommt es zu einer schnellen Spannungsrissbildung an der Schweißnaht des Verdampfers, der Unterschied im Wärmeausdehnungskoeffizienten führt zum Versagen der Dichtung des Beobachtungsfensters.LangzeitbetriebsdämpfungLeistungsabfall: Nach 2000 Stunden Dauerbetrieb führt der Verschleiß der Kompressorventilplatte zu einer Verringerung der Kälteleistung um 15 % und zu einer Abweichung des Widerstandswerts des Keramikheizrohrs.5. Auswirkungen auf Umwelt und InstandhaltungInfrastrukturanpassungFall: Die Leistungsschwankungen des PTC-Heizgeräts, die durch Schwankungen der Versorgungsspannung und den Wasserschlageffekt des Kühlwassersystems verursacht wurden, beschädigten den Plattenwärmetauscher.Blinde Flecken bei der vorbeugenden WartungLektion: Das Ignorieren des Überdrucks der Box führt dazu, dass Wasser in die Lagerkammer eindringt und sich Biofilm bildet und das Kondensatablaufrohr verstopft.6. Schwachstellen neuer TechnologienNeue KältemittelanwendungHerausforderungen: Probleme mit der Systemölkompatibilität, nachdem R448A R404A ersetzt hat, und Hochdruckdichtungsprobleme bei unterkritischen CO₂-Kältesystemen.Risiken der IoT-IntegrationFehler: Das Fernsteuerungsprotokoll wird böswillig angegriffen, was zu Programmmanipulationen und Cloud-Speicherfehlern führt, was wiederum den Verlust der Testbeweiskette zur Folge hat.StrategieempfehlungenIntelligente Diagnose: Konfigurieren Sie den Schwingungsanalysator, um den Ausfall des Kompressorlagers vorherzusagen, und verwenden Sie eine Infrarot-Wärmebildkamera, um die elektrischen Verbindungspunkte regelmäßig zu scannen.Zuverlässiges Design: Wichtige Komponenten wie der Verdampfer bestehen aus Edelstahl SUS316L, um die Korrosionsbeständigkeit zu verbessern, und dem Steuerungssystem werden redundante Temperaturregelmodule hinzugefügt.Wartungsinnovation: Implementieren Sie einen dynamischen Wartungsplan basierend auf den Betriebsstunden und richten Sie ein jährliches System zur Prüfung der Kältemittelreinheit ein.Die Lösungen für diese Probleme müssen in Kombination mit dem spezifischen Gerätemodell, der Einsatzumgebung und der Wartungshistorie analysiert werden. Es wird empfohlen, einen kollaborativen Wartungsmechanismus einzurichten, der den Gerätehersteller, externe Prüfinstitute und technische Benutzerteams einbezieht. Für wichtige Testobjekte wird empfohlen, ein Hot-Standby-System mit zwei Maschinen zu konfigurieren, um die Kontinuität der Tests zu gewährleisten.
