Precautions during use of high and low temperature chamber

With the rapid development of science and technology, high and low temperature chamber have become very common in our life. In particular, many daily necessities are tested with high and low temperature test chamber. It can be seen that the fields involved are also very wide. Well, in the process of using the high and low temperature test chamber, there are many details that need our attention. Do you know? If you don’t know, please take a look at the following introduction.

First: Sample placement position, the high and low temperature test chamber depends on the wind circulation, so the sample cannot be too large and the volume cannot exceed 1 / 3 of the working room space. If it exceeds, the air circulation in the test chamber may be affected, thus affecting the uniformity of the equipment. When using the high and low temperature chamber, the test sample shall be placed in the middle of the working room, and the upper air duct shall not be blocked or directly placed on the surface of the chamber;

Second: Sample material, the high and low temperature chamber cannot detect any inflammable, explosive and corrosive substances. If the test sample is water, it must be stored in a container and must not be spilled;

Third: Maintenance, after using the high and low temperature chamber, wipe the chamber with a dry cloth. Do not use alcohol, gasoline or other organic solvents, nor directly splash water on the test box. Once the high and low temperature test enters the water, please stop using it immediately, otherwise there may be electric leakage, electric shock, fire and other hazards;

Fourth: Pay attention to scalding, do not open the door of the high and low temperature chamber when doing the test. Opening the chamber door at high temperature will cause scald to the operator, while doing the low temperature test will cause frostbite to the operator, and may also cause the evaporator to freeze, thus affecting the cooling effect. If the chamber door must be opened, protection must be done.

Fifth: Before starting the compressor of the high and low temperature chamber, check whether the suction and exhaust stop valve and the valve in the system that should be opened are in the correct position, and check whether the power supply voltage and the ambient temperature are within the specified range;

Sixth: During the operation of the high and low temperature chamber compressor, the suction and discharge pressure shall not exceed the use range. Listen to the operation sound of the compressor. Except for the clear rising and falling sound of the inlet and exhaust valve pieces, other parts shall not have knocking sound;

Seventh: If leakage is found during the operation of the high and low temperature chamber compressor, it should be handled in time. When the compressor stops for a long time, the refrigerant should be recovered into the accumulator and the exhaust stop valve should be closed;

Eighth: After the high and low temperature chamber test, cut off the power supply of the whole machine. After each test, take out the sample and clean the equipment tank;

Ninth: When using this kind of high and low temperature test chamber, please read the instructions carefully before operating the machine. It is strictly prohibited for non professional personnel to operate the high and low temperature alternating damp heat test chamber.

There are many matters needing our attention in the process of using the high and low temperature chamber. If we do not pay attention to them, not only the test results will be affected, but also the equipment will be damaged. Therefore, after purchasing the high-quality LISUN high and low temperature test chamber, customers should also know more about the precautions for the use of this test chamber, so as to better operate the high and low temperature chamber.
