Thermal shock test chamber is a high-precision, high-performance environmental test equipment, can simulate -65 ° C to high temperature 180 ° C climate environment, is mainly used to assess and determine the detection of instrumentation, machinery, electrical and electronic products, such as the whole machine and parts and components in the high and low temperature impact test after the parameters and performance. For manufacturers to confirm the quality of product reliability, it is an indispensable test tool. In the process of equipment use, the operator's good use of skills and maintenance methods, will extend the service life of the thermal shock test chamber.

1. The condenser is sticky with dust will make the compressor high-pressure switch jump off and produce false alarms, therefore, monthly vacuum cleaner will be available to the condenser cooling mesh attached to the dust sucked out or boot after the use of hard bristles brush, or high-pressure nozzle to blow the dust clean;

2. Around the body and the bottom of the ground should be kept clean at all times, so as to avoid a large amount of dust sucked into the unit to produce accidents or reduce equipment performance;

3. When opening and closing the door or taking specimens from the thermal shock test chamber, it should not be allowed to touch the sealing strip on the door;

4. A year to check the core of the thermal shock test chamber - refrigeration system, check whether the copper pipe leakage, various joints, interfaces have no responsible leakage, if any, please notify the manufacturer;

5. Thermal shock test chamber humidifier and water tank should be cleaned frequently, so as not to produce scale, affecting the dissemination of steam, generally every time the test is done to clean once, timely exclusion of scale is conducive to prolonging the life of the humidifier tube, to ensure a smooth flow of water; in the cleaning of the use of copper brushes scrubbing, and then cleaned with water;

6. The distribution room should be cleaned and overhauled more than once a year, the node of the loose will make the whole thermal shock test chamber in a dangerous working condition, light is burned components, heavy is fire, alarm and life safety;

7. Wet and dry ball gauze is often checked, when the gauze becomes hard or unclean should be replaced in a timely manner, it is recommended that a 3-month replacement;

8. The water pipeline is easy to plug easy to leak the device, need to regularly check whether the phenomenon of water leakage plugging, if so, please promptly exclude or notify the manufacturer;

9. Humidifier storage water should be replaced once a month to ensure that the water quality is clean, smooth water flow;

10. When the test product time arrives to take the product, must be in the state of shutdown and the staff must wear a good dry, anti-electricity, moisture-resistant gloves to pick up and put the product.

When the thermal shock test chamber in doing high temperature test, if the temperature change does not reach the test temperature value, you can check the electrical system, one by one to rule out, on the contrary, if the temperature rises slowly, you can check the wind circulation system, look at the wind cycle of the adjustment of the baffle is normally open.

If the low temperature feel test indicators can observe the temperature change, is the temperature drop slower not the temperature to a certain value after the temperature has a tendency to rise, do the low temperature test before the studio must be dried, two box thermal shock test chamber so that the studio to keep dry before the test samples into the chamber, the chamber samples can not be put too much, it will lead to the chamber of the wind can not be circulated. Temperature shock test chamber in the humidity and heat test, the wet bulb sensor on the gauze drying will cause the actual humidity and target humidity related to a large number of people to do the test should be the structure of the test chamber and some operating rules have an understanding.

Poor ambient temperature may also cause the failure of the two-box thermal shock test chamber. TEMAK recommends that the temperature is set to 5-28 degrees, humidity should be in the 35-75% or so can be, two-box thermal shock test chamber machine operators must know some maintenance tips to ensure that the service life of the product.
