Cleaning Method of Condenser in Rapid Temperature Change Test Chamber
Rapid temperature change test chamber is a kind of high-precision and high-stability experimental equipment, which can carry out temperature changes in a short time to test the performance changes of materials and products at different temperatures. It is mainly used to detect the performance of products under rapid temperature changes and limit temperature conditions, and is widely used in semiconductor chips, scientific research institutions, quality inspection, new energy, optoelectronic communications, aerospace military industry, automotive industry, LCD display, medical and other science and technology industries.
After handing over the machine to the customer, in addition to instructing the precautions of equipment operation, it will also emphasize the daily maintenance of the equipment. After a long period of operation, Rapid temperature change test chamber should pay special attention to the maintenance of the refrigeration system, because the refrigeration system is not only a complex manufacturing process but also the core of the equipment refrigeration, and the next will focus on understanding the cleaning method of the condenser in the refrigeration unit.
1, Chemical pickling and scaling
For vertical and horizontal shell and tube condensers, the chemical pickling method can be used, and the weakly acidic detergent can be prepared in the pickling tank. After the pickling pump is turned on and run for 24 hours, the pickling pump is turned off, and the circular steel brush is used to brush the tube wall of the condenser back and forth, and the water is washed until all the dirt or rust stains and the scaling solution remain in the tube are clean.
2, Mechanical scaling
First, the refrigerant in the vertical shell and tube condenser is extracted, and all the valves connected to the condenser are closed, and then cooling water is normally supplied to the condenser. Use the bevel gear connected with the flexible shaft pipe washer (the diameter of the hob should be selected to be smaller than the inner diameter of the cooling pipe to scratch the inner wall) in the condenser from the top down rotary rolling mode to remove scale, because the circulating cooling water and the friction of the pipe wall generate heat, can help dirt and rust and other dirt directly washed out of the pool. After the end of descaling, drain the water in the condensate pool, clean up the dirt, and refill the water.
3, Electronic magnetic water scaling
At normal temperature, the electron magnetic water can dissolve calcium, magnesium and other salts in the cooling water of the condenser as positive and negative ions in the water. Electron magnetic water can change its crystallization conditions, can loosen the structure, reduce the tensile and compressive capacity, so that it can not form a hard scale with strong bonding force, and is converted into loose mud with the flow of cooling water and discharged.
The above is the scientific method of cleaning the condenser dirt of rapid temperature change test chamber.
Definition and Use of Temperature Cycling Test Chamber
Temperature cycling test chamber is a kind of laboratory equipment widely used in various industries, its main function is to cycle the product within a certain temperature range to simulate the operation of the product in different temperature environments. The equipment is an important tool to realize product reliability testing, quality control and product performance evaluation.
The temperature cycling test chamber is widely used and can be used for testing in various fields, such as aerospace, automotive, electronics, electric power, medical and other fields. In the aerospace sector, temperature cycle test chambers are used to test the performance of aircraft components at extreme temperatures to ensure their reliability in extreme environments. In the automotive field, the temperature cycle test chamber is used to test the performance of automotive components under different temperature and humidity conditions to ensure that the car can operate normally in a variety of environments. In the field of electronics and power, temperature cycling test chambers are used to test the performance and reliability of electronic equipment under different temperature conditions to ensure that the equipment can operate stably for a long time. In the medical field, temperature cycling test chambers are used to test the performance and reliability of medical equipment under different temperature and humidity conditions to ensure the normal operation of the equipment.
The working principle of the temperature cycling test chamber is to carry out the cycling test by controlling the temperature and humidity in the chamber. The device has a variety of temperature control modes, such as constant temperature control, programmed temperature control, programmed temperature control, etc., which can be selected according to needs. During the test process, the temperature cycling test chamber will place the product in different temperature environments for testing to simulate the use of the product in different environments. After the test is completed, users can improve and upgrade the product according to the test results to improve the reliability and performance of the product.
In short, the temperature cycling test chamber is a laboratory equipment widely used in various industries, and its main function is to cycle the product within a certain temperature range to simulate the operation of the product in different temperature environments. The equipment can be used for testing in various fields, such as aerospace, automotive, electronics, power, medical and other fields, and is an important tool to achieve product reliability testing, quality control and product performance evaluation.
