Zhongshan nitrogen machine manufacturers for nitrogen machine purity does not solve the problem. I have two nitrogen machines in my unit, and the purity never goes up, at 99. About 8%.

The unit is a pressure swing adsorption nitrogen machine, but the pressure of the two pressure swing adsorption towers is generally only about 0.6Mpa!! The purity is about 99.8, the purity has been very low, the purity is not related to the adsorption pressure of the two adsorption towers ？？？？ Previously in 0.7-0.8mpa. Purity can be up to 99. 99%!!

For the high purity of nitrogen, generally need to reach 99.9% ~ 99.99%, that is, the national standard in the oxygen free requirements; PSA carbon molecular sieve nitrogen production unit can maintain constant pressure supply in the production process to ensure the normal operation of the production line; Nitrogen does not contain dust and heat source and can be used for injection potting.

Some molecular sieve nitrogen machine due to the factory fashion sieve is not tight enough or molecular sieve quality problems. Will produce purity drop or spray screen failure! Some of the decline is caused by molecular sieve poisoning caused by not handling the purification of oil and water in the air in use!

Generally, when nitrogen is produced in Huizhou nitrogen nitrogen machine equipment, the reasons for the decline in nitrogen purity of the nitrogen machine are:

1. The adsorption pressure of PSA nitrogen maker is unstable, such as too high, more than 0.8Mpa or too low, less than 0.6Mpa.

2. There is too much water and oil in the gas source

3, the outlet part of the interface leakage

4. The pressure of air intake rises too fast

5. Molecular sieve poisoning of pressure swing adsorption nitrogen making machine equipment

The solution measures that can be taken are as follows to improve the nitrogen purity of the PSA nitrogen making machine:

1, reduce the air pressure, increase the intake pressure

2. Add a storage tank to the air intake

3. Remove and reinsert

4. Replace the molecular sieve

5. Adjust the inlet regulating valve of the nitrogen machine to reduce the intake volume, and install an oil-water separator before the inlet.
