After a long time of use, high and low temperature test chambers are inevitably large and small problems. For example, high and low temperature test chambers have poor cooling performance and cannot be started. Due to improper use of humans, it is easy to cause the life of high and low temperature test chambers due to the cost of electricity. shorten. If you choose "good", you should use "good". With these common problems, Xiaobian will answer you one by one.
(1) How to prevent leakage of cold air from high and low temperature test chambers?
Answer: After using the high and low temperature test chamber for a long time, the cold air in the high and low temperature test chamber leaks due to the aging deformation of the sealing strip on the door, which reduces the cooling effect. The method of inspection is to open the handle flashlight into the test box, close the door, and carefully observe whether there is a gap between the high and low temperature boxes. If the seal is cleaned with detergent powder, the seal at the leak will be opened. , put a piece of sealant paper, put the seal on the original, and then check if it still leaks. Repeat the test for this patch until there is no light leakage.
(2) Why does the high and low temperature test chamber not start?
a, the power supply voltage is within the scope of the specification, the general requirement voltage is 380V; if it is not in this range, it should be equipped with a voltage regulator or a professional electrician to solve;
b. The line in the box is broken;
c. The ambient temperature placed in the high and low temperature test chamber should not be lower than 5 degrees, otherwise the compressor will not start;
d, compressor failure;
e, the low temperature compensation switch is not turned on, the low temperature compensation switch is faulty, and the low temperature compensation heating wire cannot be turned on;
The reflective spray-painted cloth can be made into large-scale outdoor billboards for highways, roads, mines and other outdoor environments. There is no need for lighting at night, only vehicle light and can make the advertising content clear and bright, with the same effect in the day.The reflective spray painting cloth is composed of a reflective layer and a base layer of light box cloth. According to the difference of its reflective structure, it can be divided into standard reflective materials, wide-angle reflective materials and all sky star reflective materials.
