Reasons and solutions for the slow temperature drop of the constant temperature and humidity test chamber

Under normal circumstances, the constant temperature and humidity test chamber will reduce the temperature to a relative value according to the set time period. However, because the machine equipment is used for too long or the actual operation is not good, it will cause the temperature of the constant temperature and humidity test chamber to slow down. , 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 temperature reduction rate is very high, the 2 sets of generator sets are working separately. In the early stage of the temperature maintenance link, the 2 sets of generator sets are still working separately. When the temperature basically stabilizes, 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 be started normally during the entire operation of the environmental test chamber, and the refrigeration compressor can be started during the entire operation of the natural environment test equipment, indicating that from the main switching power supply to each The home appliance route of the refrigeration compressor is all normal, and there is no problem at the software level of the home appliance system.

3. When we did not clarify what the problem is in the constant temperature and humidity test box, we integrated the machine and equipment to further determine the problem during the whole process of operation. The machine and equipment have two refrigeration units.

Anti-corrosion method for gate valve of refrigeration compressor of constant temperature and humidity equipment test box

To put it plainly, there are two types of natural environment: theory and category. The theoretical natural environment refers to the natural environment around the gate valve installation and the commodity circulation substances inside it; the category natural environment refers to the standards around the gate valve installation. Most of the natural environment cannot be controlled, and the production process cannot be changed at will. Only under conditions that are not easy to cause harm to commodities and processing techniques, can you choose to manipulate the natural environment, such as deoxygenation of the heating furnace water, adjustment of the pH value of the alkali in the processing technology of the refinery, etc. From this point of view, the addition of desulfurizers, photoelectric catalytic maintenance, etc. also belong to 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 and so on. Its purpose is to enhance the corrosion resistance of metal materials and improve the working capacity of mechanical equipment of metal materials. Architectural paint sprayed with latex paint is the most commonly used 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 made up of anti-corrosion coatings, vulcanized rubber pastes, edible oils, organic solvents, etc., and cover the metal surface to block substances and air for anti-corrosion purposes.

Main parameters of constant temperature and humidity testing machine

1. The production experience is rich and colorful, 15 years of production experience, long-term focus on the research, development and production of constant temperature and humidity test chambers, and can quickly develop and produce constant temperature and humidity tests that meet the needs of customers’ practical activities according to customers’ practical activities. machine.

2. The supply is abundant and convenient. After many years of development, the testing equipment in Suzhou has already been completed. China’s fast-track constant temperature and humidity testing machine production industrial base has long been equipped with dozens of various types of constant temperature and humidity equipment, or even more than 100. Taiwan, can quickly satisfy the customer’s order must.

3. The materials used are more unique. The constant temperature and humidity testing machine of Suzhou Testing Instruments is more unique at the material level. The quality and quantity are solid. The Dutch refrigeration compressor is used in the whole production process of the constant temperature and humidity testing machine. , Japan ternary control panel, imported stainless steel plate and other machinery and equipment.

4. After-sales maintenance services are deeply traded. After recycling all a piece of machinery and equipment, you can get a one-year after-sales service validity period. During this period of time, the insurance insured business scale will bear the full amount of free maintenance, which is satisfactory to you Must.
