Temperature shock Test Chamber and cold and heat shock Test Chamber, divided into vertical basket type cold and heat shock Test Chamber or horizontal sliding type cold and heat shock Test Chamber, widely used in electrical, electronic products, complete machines and for cold testing Parts, rapid changes in temperature or gradients under adaptive test conditions, especially suitable for environmental stress screening (ESS) testing of electrical and electronic products.
Maintenance method:
1. The temperature shock Test Chamber should be fixed once every 3 months to clean the condenser: for the cooling system that adopts air cooling, the condensing fan should be checked regularly, and the condenser should be decontaminated and dust-removed to ensure its good ventilation and heat transfer Performance; For water cooling, in addition to ensuring that the inlet pressure and inlet temperature are within the specified range, the corresponding flow rate needs to be guaranteed, and the inside of the condenser needs to be cleaned and descaled regularly to obtain continuous heat transfer performance.
2. The temperature shock Test Chamber keeps low temperature for a long time. After completing a cycle, the temperature should be set to 110 degrees, and the chamber door should be opened in a small range for two hours of defrosting treatment. For each test, set the temperature close to ambient temperature, work for about 30 minutes, then disconnect the power and clean the studio
3 inner walls. The temperature shock test box should be cleaned regularly: due to the different cleanliness of the tested products, the evaporator will condense many fine particles, such as dust, under the action of strong wind circulation, so the evaporator should be cleaned regularly. Cleaning and balancing of circulating air blades and condenser fans Appearance of the Test Chamber: Similar to cleaning the evaporator, due to the different working environment of the Test Chamber, the circulating air blades and condenser fans will condense many small particles, such as dust, and should be cleaned regularly.
4. Cleaning of the waterway and humidifier: If the waterway is not smooth, the scale of the humidifier will easily cause the humidifier to dry and burn, which may damage the humidifier. Therefore, the waterway of the humidifier needs to be cleaned regularly.
5. If you need to move the equipment, it is recommended to operate under the guidance of technical personnel to avoid damage to the equipment. If the customer walks by himself, it is necessary to ask a professional electrician to confirm the correct circuit before starting the operation, otherwise the relevant components of the equipment will be burned.
6. If the machine is shut down for a long time, it should be turned on regularly for no less than one hour every half month, and check whether the relevant parts of the equipment are in normal operation.
