Can it still be tested with air after running for a year?

Can a urea carbon dioxide compressor (model 4M32-186) still be used for air testing after one year of operation? Last edited by lxq700918 on 2009-3-22 20:27.]

Sure, it’s just that the control parameters for each section are different from those for CO2 injection. Of course, attention must also be paid to compression units that have been in operation for a long time, as their pipes and equipment may accumulate a large amount of oil; during air testing, high temperatures can easily lead to the ignition and explosion of this accumulated oil.

It should be fine, but make sure to follow safety procedures

The hydrogen compressor here is still undergoing air test runs after its major repair.

It’s completely possible; a trial run under load is used to check the operating condition of the compressor, and it’s possible to determine the status based on that.

What is the ignition point of 68# lubricating oil?

Since it is a test run after maintenance, it is recommended that you separate the buffer tank from the machine body and purge it with steam in order to remove carbon deposits and oil residues that have accumulated over time. Compressors that use inert gases (carbon dioxide, nitrogen) can pose risks during air-based tests after long periods of operation. During the air test of the carbon dioxide compressors in our plant, a break occurred at the thin tube of the outlet buffer tank in the third stage, which caused a small burst of flames. We are using 150# lubricant. This post was last edited by lxq700918 on 2009-3-23 at 17:17

Circulating oil grade: 40# (N68); Flash point: ≥190°C. Source: http://bbs.hcbbs.com/viewthread.php?tid=400072&highlight=%D1%B9%CB%F5%BB%FA. Last edited by 1025199692 on 2009-4-3 21:51
