What precautions should we take when using liquid nitrogen machines in the lab? How can we extend their lifespan?

　   Laboratory Liquid Nitrogen GeneratorThis is commonly used equipment in the current industrial field, and it has many advantages. However, the equipment should be used correctly. If operated improperly, some malfunctions will often occur. Next, the laboratory liquid nitrogen generator manufacturer will detail some precautions during use.

　　A laboratory liquid nitrogen generator is a device that uses air as a raw material and then uses physical methods to separate the oxygen and nitrogen to obtain nitrogen. This product is a nitrogen generation device designed and manufactured based on pressure swing adsorption technology. In daily life, many operators of nitrogen generation units do not use the machine according to regulations, which can lead to some malfunctions and seriously affect its service life. Therefore, operators should not arbitrarily move the adjusted valves during use, otherwise it will affect its purity. And equipped with an air compressor, air dryer and filter according to technical requirements. This is also very important. Only daily maintenance can maintain the original effect.

　　So how to extend the service life of the laboratory liquid nitrogen generator?

　　Nitrogen generators have become essential equipment for many enterprises, but many workers do not know how to operate them or how to maintain them.

　　Laboratory Liquid Nitrogen GeneratorThe main application areas are, for example, as a protective gas in metal heat treatment processes, purification of industrial gases in chemical and various storage pipelines, production of rubber and plastic products, and exhaust for preserving packaging in the food industry. There are also some more special ones, such as purification in the beverage industry and use as a covering gas.

　　Of course, such a good product is also very good in the medical industry. Among them, the purity, stability, pressure, flow rate, etc. are different. It can meet the various needs of different customers.

　　For any machine, maintenance is very important, and good maintenance can effectively extend the service life of the laboratory liquid nitrogen generator. In addition to maintenance, the correct use of the laboratory liquid nitrogen generator is also important for extending the life of the equipment.

　　1. Turn off all power switches, including the laboratory liquid nitrogen generator, nitrogen inlet valve and sampling valve, and wait for the system and pipeline to be completely depressurized. Adjust the oxygen analyzer sampling, adjust the pressure reducing valve pressure to 1.0 bar, adjust the sampling flow meter, and adjust the gas volume to about 1. Note that the sampling gas volume cannot be too large, and start testing the nitrogen purity.

　　2. Only when the compressed air pressure reaches more than 0.7mpa can theLaboratory Liquid Nitrogen Generatorstop valve be opened, and the pressure change of the adsorption tank and whether the pneumatic valve can work normally need to be observed at the same time.

　　3. When the regeneration tower pressure is zero and uniform, the pressure of the two towers should be close to half of the original working tower.

 4. Turn off the entire system and each part of the system. When the adsorption tank pressure of the nitrogen generator reaches about 0.6 MPa, observe whether the nitrogen generation system is working normally.
