Learn these, you are also a "maintenance" of liquid nitrogen generator

This is a reliable nitrogen generator used to separate or generate very clean nitrogen. Using it can solve many problems caused by the use of nitrogen, and can reduce costs. It puts the certain flow rate and purity of ordinary nitrogen and hydrogen together into the installation and arrangement. After enough mixing in the mixer, it enters the installation and arrangement of the deaerator equipped with a palladium catalyst. The chemical reaction reaches the purpose of deoxygenation. After deoxidation, the water vapor in the liquid nitrogen is dehydrated from the beginning and the end of the cooler, and then the liquid nitrogen enters the monotoner monotonously, so that the dew point of the liquid nitrogen reaches about -60 ℃. The monotoner that has absorbed the plump water vapor is regenerated to prepare for the next cycle of adsorption work. After the monotonic liquid nitrogen filter removes dust, the high-purity liquid nitrogen is obtained, which is the liquid nitrogen generator.

When the following problems occur in the process of using the liquid nitrogen generator, you can fix it yourself:
1. When the liquid nitrogen pressure does not reach the set value, the flow meter should be observed first. If the flow rate display is larger than usual, it can basically be concluded that there is a gas leakage problem in the entire system.
Solution: first turn off the power, remove the gas path, the liquid nitrogen outlet needs to be sealed with a sealing nut, and then turn on the power of the liquid nitrogen generator to see if the pressure can reach the set value and whether the flow rate display can reach "000" If the flow display can return to zero, it means that there is no air leakage in the instrument itself. Then, please check the pipeline after the gas outlet and the air-using equipment for air leakage. If the flow rate display cannot return to zero, there is a leak point. Please use soap to check if there is a leak in the drying tube.
2. A noise occurs during operation.
Solution: Use a wrench to properly adjust the tightness of the nut on the instrument, not too tight; if it does not work, the instrument shell needs to be disassembled and the inside cleaned (mainly due to impurities inside), if it is not possible after cleaning, it must be replaced with a new one of.
3. During operation, the meter shows that the digital large pressure cannot reach the set value.
Solution: This is caused by air leakage, and it is necessary to conduct a comprehensive leak detection on the gas circuit, especially the drying room and the battery.
