　　Liquid Nitrogen GeneratorWhat is it like? How to maintain it?

　　The liquid nitrogen generator uses cryogenic mixed refrigerant throttling refrigeration technology, skid-mounted design, compact structure, continuous and convenient liquid nitrogen supply, and can be used as a regional source of a small amount of liquid nitrogen supply. It consists of an air compressor, freeze dryer, filter, nitrogen generator, and buffer tank. The nitrogen generator is non-standard equipment, and the prices of air compressors, freeze dryers, and tanks vary among different Brands. Too cheap supporting equipment will also affect the overall service life.

　　The liquid nitrogen generator is a nitrogen generation equipment designed and manufactured based on pressure swing adsorption technology. It helps to keep the gas flowing smoothly in the system, reduce the discharge temperature of compressed air, and separate water, oil and other impurities from the compressed air according to the decrease of compressed air temperature, thus helping to prolong the service life of the post-processing equipment and improve the quality of compressed air.

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

　　The liquid nitrogen generator uses an automatic compressed cylinder device and a unique air intake method, so that the airflow direction in the adsorber remains unchanged, avoiding fatigue and wear of the adsorbent during frequent switching cycles, effectively ensuring the service life of the adsorbent for up to 10 years. The inertial force loading method of the adsorbent makes the filling density of the adsorbent higher, the filling is tighter, prevents the adsorbent from crawling and pulverization, improves the adsorption separation efficiency, and thus ensures and correspondingly extends the service life of the adsorbent.

　　This liquid nitrogen generator is mainly used for school laboratory teaching, livestock refrigeration, bearing production thermal expansion and contraction, and beverage bottling preservation. Using carbon molecular sieve as the adsorbent, under certain pressure, the different diffusion rates of oxygen and nitrogen in the pores of the carbon molecular sieve are utilized. That is, the diffusion and adsorption of oxygen by the carbon molecular sieve are far greater than that of nitrogen, achieving the purpose of air separation. It uses a programmable controller to control the opening and closing of multiple valves to realize the alternating cycle of pressure adsorption and pressure adsorption of two adsorption towers.

　　The following areLiquid Nitrogen Generatormaintenance precautions:

　　1. Stabilize the power voltage to eliminate damage to the controller and solenoid valves caused by power problems.

　　2. Always pay attention to the pressure of the atmospheric storage tank and do not let it fall below the rated value.

　　3. Do not use corrosive solutions such as gasoline or thinner.

　　4. Operators should regularly observe the three pressure gauges on the machine. In the event of equipment deployment obstacles, record their pressure changes and check the flow meter and nitrogen purity environment, as well as the purity of the nitrogen connected to the outlet.

　　5. Regularly check the heat sink of the air dryer every week to ensure it is clean, so as to avoid affecting the performance and service life of the dryer due to poor heat dissipation.
