高低温冲击试验箱、冷热冲击试验箱（三厢）Highandlowtemperatureimpacttestcase

Use equipment: thermal shock test chamber is industry of metal, plastic, rubber, electronics and other materials necessary test equipment to test the structure of the material or composite material, in an instant by a very high temperature and low temperature continuous environment bear the degree, can in the shortest time test sample due to thermal expansion and contraction caused by the changes of chemical or physical damage.

Main technical parameters of the equipment specification material:

(model appearance of technical information are subject to change without notice, Ting Yi has the power of final interpretation)

Maintenance considerations and methods:

The operation of the high and low temperature impact test chamber is divided into five parts: preprocessing, initial detection, test, recovery, and final detection. Yi Ting and share it with the content of process:

1 pretreatment: the test sample is placed in the normal test atmosphere, until the temperature is stable.

2 initial detection: the test samples and standard requirements, in line with the requirements directly into the high and low temperature impact test box.

3 test:

1) the test samples should be in accordance with the standard requirements placed in the test chamber, and the test box (room) temperature rise to a specified point, keep a certain time to test samples to reach stable temperature. For a long time.

2) after the end of the high temperature phase, in 5min test samples of conversion to have been adjusted to 55 DEG C and low temperature test chamber (room), maintain 1 hour or until the test sample to reach steady temperature, for a long time.

3) after the end of the low temperature phase, in 5min test samples of conversion to have been adjusted to 70 DEG C high temperature test box (room), maintain 1 hour or until the test sample to reach steady temperature, for a long time.

4) repeat the above experimental method to complete the three cycle. According to the size of sample size and space, time may be a slight error.

4 recovery: the test samples taken from the test chamber, should be under normal atmospheric conditions to resume, until the test samples to achieve temperature stability.

5 the final test: the extent of the damage in the control standard and other methods to assess the results of the test.

Not test

Explosives, flammable substances, combustible materials, oxides of the nature of the class, flammable materials

1 do not put the test equipment power supply in the power supply, otherwise it will increase the equipment power supply load. Unless the device is left with a sample power interface.

2 test is strictly prohibited flammable, explosive, high corrosion, strong radiation items.

3 equipment under the state or the operation of the power of handling, maintenance.

1, high temperature scald, hot and cold shock test box in the high temperature test case temperature is very high. Test process or the end of the test, such as the need to open the box, open the door to be particularly careful, remember, along the way to walk in the direction of walking, so as not to burn.

2, low temperature frostbite, thermal shock test box in low temperature test box temperature is very low. In the process of test or test is finished, such as the need to open the door to take extra care to avoid frostbite.

3, high temperature scald, hot and cold shock test box in the high temperature test case temperature is very high. In the course of the test or the end of the test, if you need to open the door to be particularly careful, so as not to burn.

4, electric shock, although the device has a sound anti shock measures, but still need to pay attention to, especially the electrical control system, the work of the case, do not touch electrical parts.

Maintenance method

A. cold and heat shock test machine refrigeration unit of the radiator (condenser) should be regularly maintained, keep clean. Dust sticky condenser will make the high-pressure compressor switch jump off and produce false alarms, the condenser should be monthly maintenance, condenser cooling network on chip attachment of the dust suction or boot using hard the hair brush or with high pressure gas mouth blown clean of dust with a vacuum cleaner.

B. open and close the door or take the test from the furnace, not let the goods on the door to prevent the contact edge glue, glue edge damage and shorten the life.

C. around the body and at the bottom of the ground should be kept clean, so as to avoid a large number of dust suction unit to produce an accident and reduce performance.

Please inform us or direct handling D. thermal shock test machine refrigeration system is the core of this machine, please half the inspection of all brass of any leakage of snow, the horn joint, welding mouth, such as the leakage of grease.

E. distribution disc large current contact, power distribution room of every year at least clean maintenance more than once, the loose contact will make the equipment in hazardous work state, light burned out component, fire, alarm, personal injury is very dangerous. When cleaning cleaning using a vacuum cleaner will indoor dust suction can be among.

F. thermal shock test machine power distribution box and two over temperature protection device setting value, please do not just debugging, factory tuned the protection switch is to protect the heating tube air burning and alerts. Set point = temperature set point 20 DEG to 30 DEG C.

H. hot and cold shock test machine when the test product time to take products, must be in the shutdown state and the staff must wear a good drying, electricity, temperature resistant gloves to take and put products.

Internal and external cleaning and maintenance of I. cold and heat shock test case.

J. thermal shock test machine before the operation should be internal impurities (material) clearance.

The K. distribution room is cleaned at least once or more every year, and can be used for cleaning the indoor dust. The exterior of the box must be cleaned more than once per year, which can be cleaned with soap and water.

choose

Desire to buy a product, need to have a general understanding of the product, what is hot and cold impact test box?? a Shanghai court tomorrow equipment plant hot and cold impact test box by cool storage, tested the products stationary of hot and cold alternately impact, testing products in rapid temperature changes after the performance and parameters. That is to say, it is used to test composite materials and structural materials, at the moment, and high temperature and low temperature by the continuous environment can bear degree, that is to say, in the shortest time to test its due to thermal expansion and contraction caused by the changes of chemical or physical damage. The applicable objects including metal, plastic, rubber, and other electronic materials.

Thermal shock test box purchase should pay attention to five aspects: temperature shock, test load, return time, in addition to the frost time, sensors placed.

When purchased, they have their own requirements, the impact of the temperature is to refer to the actual test area can run to the maximum range of temperature. Attention is not the limit temperature of preheat and pre cooling chamber; the direct effect of test load can be placed on the number of test products. Generally speaking, the bigger the weight is, the better it is, the time it takes to switch from one point to the other. Our common specification agreed to less than 5min. The smaller the time the better; the longer the cream, the longer the better. Now the next Ting can do 1000 cycle defrosting time is very ideal. Defrost interval is short that air tightness of the device is worse; the sensor must be positioned within the test area. If placed in the duct interior, and although the test area only 10cm distance, but this energy difference is quite large. Temperature change test and could not reflect the product surface.
