Reasons and solutions for the slow cooling of the constant temperature and humidity Test Chamber
In general, the constant temperature and humidity Test Chamber will reduce the temperature to a relative value according to the set time period. However, due to the prolonged use of equipment or poor operation, the temperature of the constant temperature and humidity Test Chamber will slow down. , and now we have a technical discussion on how to solve this problem.
1. One is the leading generator set and the other is the auxiliary generator set. When the cooling rate is high, the 2 generators work separately. In the early stage of the temperature maintenance link, the two generating sets are still working separately. When the temperature is basically stable, the auxiliary generator set stops working, and the main generator set keeps the temperature stable.
2. Because the temperature cannot be maintained, observe whether the refrigeration unit can start normally during the entire operation of the environmental Test Chamber, and whether the refrigeration compressor can be started during the entire operation of the natural environment test equipment, indicating that each refrigeration compressor from the main switching power supply The home appliance wiring is normal, and there is no problem at the software level of the home appliance system.
3. When we don't know what the problem is in the constant temperature and humidity Test Chamber, we integrate the machinery and equipment to further determine the problem during the entire operation process. Machines and equipment have two refrigeration units.
Anti-corrosion method for refrigeration compressor gate valve of constant temperature and humidity equipment test box
To put it bluntly, there are two kinds of natural environments: theory and category. Theoretical environment refers to the environment around the gate valve installation and the circulation substances inside; the natural environment category refers to the conditions around the gate valve installation. Most of the natural environment is uncontrollable, and the production process cannot be changed at will. Only under the condition that it is not easy to cause harm to products and processing technology, can we choose to control the natural environment, such as deoxidation of heating furnace water, pH adjustment of alkali in refinery processing technology, etc. From this point of view, the addition of desulfurizers, Photocatalytic maintenance, etc. It also belongs to the manipulation and erosion of the natural environment. Metal surface layer solution Metal surface layer process treatment can help sleep coating, surface layer infiltration, surface air oxidation passivation treatment, etc. Its purpose is to enhance the corrosion resistance of metal materials and improve the working ability of metal materials mechanical equipment. Spraying architectural paint with latex paint is a common anti-corrosion method, and it is also an indispensable anti-corrosion paint and identification mark on industrial valves of refrigeration compressors.

Architectural coatings are also classified as non-metallic materials. They are generally composed of anti-corrosion coatings, vulcanized glue, cooking oil, organic solvents, etc., covering the metal surface to block substances and air, and play a role in anti-corrosion.
