Maintenance methods for laboratory liquid nitrogen machines

Laboratory Liquid Nitrogen GeneratorMainly used for school laboratory teaching. Beverages are kept fresh by inverting the cans. Using a carbon molecular sieve as an adsorbent, under a certain pressure, the different diffusion rates of oxygen and nitrogen in the air in the pores of the carbon molecular sieve achieve 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, convenient shutdown, easy maintenance, and low production cost.

Laboratory Liquid Nitrogen GeneratorIt is a nitrogen generation equipment designed and manufactured based on pressure swing adsorption technology. It helps the air in the system to flow smoothly, reduces the discharge temperature of the compressed air, and separates water, oil, and other impurities from the compressed air according to the decrease in compressed air temperature. This helps to extend the service life of the post-processing equipment and improve the quality of the compressed air.

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

InLaboratory Liquid Nitrogen Generatorthe long-term use process, maintenance should be paid attention to in order to extend the effective life of the equipment. The maintenance methods are briefly introduced below.

1. During operation, if a large amount of black dust is sprayed from the cavity, the machine should be stopped immediately, and the cause should be investigated to prevent further aggravation of the carbon powder molecular sieve.

2. The carbon molecular sieve is its core. In order to prevent pollution and loss of function, strictly control the oil content of the air compressor exhaust, and regularly replace the precision filter element and activated carbon in the high-efficiency oil remover.

3. Regularly checkLaboratory Liquid Nitrogen Generatorthe pressure gauge of the compressed air cylinder. If there is no pressure or the pressure drops during desorption, the cylinder cannot press the carbon molecular sieve normally anymore, and the carbon molecular sieve cannot be pressed. The problem should be solved in time to avoid the generation of molecular sieve powder. When the carbon molecular sieve gap reconstruction or normal loss leads to a carbon position alarm, immediately stop adding carbon molecular sieve. The storage, transportation, and loading and unloading of the carbon molecular sieve are harmless to the human body. When filling the carbon molecular sieve, wear goggles, a respirator, and an exhaust fan. After filling, wash the skin contact areas with soap.
