Matters needing attention when installing and maintaining the thermal shock test chamber

The thermal shock test box is a necessary test equipment for the metal, plastic, rubber, electronic and other material industries. It is used to test the material structure or composite material. It can withstand the extreme high temperature and low temperature in an instant. Detect the chemical change or physical damage caused by thermal expansion and contraction of the sample in the shortest time. The test methods that the thermal shock test chamber meets: GB/T2423.1.2, GB/T10592-2008, GJB150.3 high and low temperature shock test. Principle and function The high and low temperature impact box is a necessary testing equipment for the metal, plastic, rubber, electronic and other material industries. It is used to test the structure of materials or composite materials, which can be tolerated in a continuous environment of extremely high temperature and extremely low temperature in an instant To detect the chemical change or physical damage caused by thermal expansion and contraction of the sample in the shortest time. Divided into two-chamber and three-chamber, the difference lies in the test method and internal structure, the product conforms to the standards: GB/T2423.1-2008 test A, GB/T2423.2-2008 test B, GB-T10592-2008, GJB150 .3-198, GJB360A-96 method 107 temperature shock test requirements. There are strict requirements for the installation and maintenance of the thermal shock test chamber. Improper operation will affect the performance and service life of the machine. The Standard Group briefly lists some standardized operating methods for the thermal shock test chamber. 1. The temperature test box cannot be installed upside down. It must be placed horizontally on the floor to make the operating door of the temperature test box easy to open and reduce the noise during mechanical operation; 2. There should be a good ventilation space behind the test box for the condenser Can play the role of heat dissipation. And avoid direct sunlight, keep away from heating elements such as stoves, so as not to affect the freezing effect; 3. Although the inner and outer materials of the test box are made of high-grade stainless steel, but the place with damp running water will easily cause the machine parts and the electronic control center to have adverse effects and reduce The efficiency should be avoided as much as possible; 4. Please use a dedicated switch for the power switch, and do not use the soft cord of the SW plug with other electrical machinery. Do not place it on the floor or in a damp place to avoid stepping on or leakage; 5. The power supply voltage is too low An autotransformer should be installed at the place to increase the voltage to the rated value, so as not to burn the compressor motor because the voltage is too low to start; 6. During the test, the operating door should not be opened for a long time to avoid water mist in the box; 7 .The inside of the warm test box should be kept clean at all times. When the outer box is clean, you can apply a little varnish and polish it with a soft dry cloth. If it is too dirty, use a neutral lotion and water to clean it. Never use a brush to polish Wipe the inside and outside of the machine with powder, acid, benzene oil or hot water. The back or the wall is most likely to be covered with dust, and the heat dissipation of the condenser should be prevented. You should always pay attention; 8. If this model is water cooling (WATER COOLING) At this time, special attention should be paid to the treatment of water quality, and the use of ground water should be avoided as much as possible. Because ground water contains more minerals, it is easy to produce scale, which will affect the cooling effect and reduce the life of the machine.

Collectively, the effect of textile testing equipment on industrial society has been to eliminate tensile tester manufacturers and drastically reduce the time long associated with tensile tester manufacturers.
