Tell you about the solution to the problem of high and low temperature test chamber
The core parts of the high and low temperature test chamber are the three major parts of electronic control, sheet metal, and refrigeration. Among them, refrigeration is the main source of problems. Let's first understand the most common problems. What to do if the low temperature cannot be maintained, the high and low temperature test chamber manufacturer is for you Tell about the solution: Touch the exhaust and suction lines of the main unit R23 compressor of the high and low temperature box with your hand. If you find that the temperature of the exhaust line is not high, the temperature of the suction line is not low (no frost), which also It illustrates the lack of R23 refrigerant in the host group. One of the high and low temperature test chamber is the main unit and the other is the auxiliary unit. When the cooling rate is large, the two groups of units work at the same time. At the beginning of the temperature maintenance stage, the two groups of units still work at the same time. After the temperature stabilizes, the auxiliary unit will stop working, and the host group will maintain the temperature drop and stability. If the host group R23 leaks, the cooling effect of the host group will be insignificant. Since the two units are working at the same time during the cooling process, there is no phenomenon that the temperature is not stable, and the cooling rate is indicated to decrease. First observe whether the refrigeration compressor of the high and low temperature box can be started during the operation of the high and low temperature test box. If the compressor of the high and low temperature box can be started during the operation, it means that the electrical circuits from the main power supply to each high and low temperature box compressor are Normally, there is no problem in the electrical system. When there is no problem with the electrical system of the high and low temperature box, continue to check the refrigeration system.
Lipsticks are intended to add color and texture to the Lips and often come in a wide range of colors, as well as finishes such as matte, satin and lustre. Lip stains have a water or gel base and may contain alcohol to help the product stay on the lips. The idea behind lip stains is to temporarily saturate the lips with a dye. Usually designed to be waterproof, the product may come with an applicator brush, rollerball, or be applied with a finger.
