Users need to pay attention to their daily maintenance when using the nitrogen machine:
1, the air compressor should be regularly maintained, air filter, oil filter, oil should be regularly arranged according to the manual manufacturer to replace.
2, the cold and dry machine should regularly check the refrigerant pressure, so as to timely supplement, the heat sink dust should be blown with compressed air every day, the filter element should be replaced regularly, the normal is 8000H, depending on the specific situation, pressure difference and so on.
3, open the air storage tank sewage outlet once a day to discharge condensed water and other impurities in the air.
4, check the automatic drainer every day, so as not to clog and lose the drainage effect. If it is blocked, you can slightly open the manual valve, close the self-discharge valve, and then remove the automatic drainer, decompose and clean. When cleaning the automatic drainer, use soap to clean it.
5, mainly check the working pressure of the adsorption tower of the nitrogen machine, purity, flow, etc., and make records for later verification.
6, the activated carbon in the activated carbon filter is generally recommended to be replaced once a year.
7, silencer if there is black smoke, indicating molecular sieve powder, immediately stop, maintenance.
8. The nitrogen analyzer is calibrated periodically, and it is recommended that it be calibrated once every six months.
9, to check the sensitivity of the pneumatic valve and the solenoid valve, the wear of the pneumatic valve will affect the purity of nitrogen, which is a wearing part.
10, the safety valve should be calibrated to the boiler inspection office every year.
The above is the common failure of the user in the process of using the nitrogen machine, for reference.
