Laboratory liquid nitrogen machine maintenance methods

　　Laboratory Liquid Nitrogen GeneratorPrimarily used for laboratory teaching in schools. Beverages are kept fresh by inverting the cans. Using a carbon molecular sieve as an adsorbent, under a certain pressure, utilizing the oxygen and nitrogen in the air, the diffusion speed of the carbon molecular sieve in the pores is different, achieving the purpose of air separation. The characteristics of the laboratory liquid nitrogen generator are: room temperature production, simple process, high degree of automation, low susceptibility to damage, easy shutdown, convenient maintenance, and low production cost. Therefore, let's understand the maintenance methods of the laboratory liquid nitrogen generator below.

　　Laboratory Liquid Nitrogen GeneratorIt is a nitrogen generation equipment designed and manufactured based on pressure swing adsorption (PSA) technology, which helps the smooth flow of air in the system, reduces the discharge temperature of compressed air, and separates water, oil, and other impurities from the compressed air according to the decrease in compressed air temperature, extending the life of the post-treatment equipment and improving the quality of compressed air.

　　The laboratory liquid nitrogen generator adopts a special molecular sieve filling technology and a gas grading design, with a high adsorption rate and effectively preventing molecular sieve differentiation. Three-stage filtration, air angle valve control, 3 million trouble-free operation PLC microcomputer automatic control, and remote computer online control.

　　In the long-term use of the laboratory liquid nitrogen generator, maintenance is necessary to extend the service life of the equipment. The maintenance methods are briefly introduced below.

　　1. During operation, if a large amount of black dust is ejected from the inside of the test box, the machine needs to be stopped immediately, and the cause needs to be investigated to prevent further deterioration of the carbon powder molecular sieve.

　　2. The carbon molecular sieve is its core component. To prevent pollution and loss of function, strictly control the oil content of the air compressor exhaust, and regularly replace the filter element and activated carbon in the oil remover.

　　3. Regular inspectionLaboratory Liquid Nitrogen Generatorof the compressed cylinder pressure gauge. If there is no pressure, or if the pressure drops during disassembly and assembly, the cylinder will not be able to press the carbon molecular sieve normally, and the carbon molecular sieve will be pressed and unable to move. The problem needs to be solved immediately to avoid the generation of molecular sieve. If the carbon molecular sieve needs to be rebuilt due to loss, or if a carbon level alarm is triggered due to normal wear and tear, immediately stop adding carbon molecular sieve. The storage, transportation, and loading and unloading of the molecular sieve are harmless to the human body. When filling the carbon molecular sieve, medical goggles, respiratory filters, and an exhaust fan should be worn, and the skin contact area should be washed with soap after filling.
