Analysis of various factors affecting nitrogen machine

The nitrogen making machine is a high-tech product of machine, electricity and instrument, which is particularly important for the stable long-term use of the equipment. We see that the self-made nitrogen unit is not difficult, affecting the following two points: 1, stability control valve: PSA nitrogen machine, must have the following characteristics: A. Valve material performance is good, absolutely no leakage; B. Receive the control signal within 0.02 seconds after completing the opening or closing movement; C. Can withstand frequent opening and closing, to ensure that there is enough long life; 1.1, the cause of valve failure, in general, in each cycle of each control valve (about 120 seconds) to switch once, in a year to produce machine nitrogen 300 working days, 24 hours a day continuous dynamics, 4 minutes of adsorption and desorption cycle, and then each valve needs to open and close about 200,000 per year. The failure of only one valve will affect the normal operation of the entire equipment. Therefore, the most important part of the continuous service life of the valve nitrogen machine is stable and reliable.

Performance index of carbon molecular sieve

B. Nitrogen production A hardness (cubic meters/TH)C recovery rate (N2 / air)% of the packing density of carbon molecular sieve manufacturers the above indicators have been in the factory sign, but only as a reference data, how to maximize the efficiency of carbon molecular sieve, which is a direct relationship with the length to diameter ratio of each nitrogen manufacturer and the adsorption process is a direct relationship. At the same time, the service life of the molecular sieve is very special

Effect of oil, gas and water on molecular sieve

Because the air containing oil and water vapor, through the compressor, there is no strict air purification treatment, oil vapor is easy to adsorb on the carbon molecular sieve, and it is difficult to desorption, fill the molecular sieve pore size, resulting in the failure of molecular sieve "poisoning". Therefore, it is crucial to set a strict air purification device before the compressed air enters the adsorption tower to ensure the service life of the screen ring. Although the water in the molecular sieve is not fatal, it will increase the adsorption load of the molecular sieve, affect the adsorption capacity of O2 and CO2, make the compressed air dry to remove water, and improve the molecular problem of sieve adsorption capacity and stability can not be ignored
