Excuse me, does that expert know what causes the oil in a diaphragm compressor system to turn black?

Thread Content

Our company is using diaphragm compressors manufactured by Beijing Jingcheng Environmental Protection. 10 days ago, we noticed that the oil in one of the machines had turned black. Recently, we drained the oil from that machine and replaced it, but the oil changed color to black again within less than 12 hours. If anyone knows the reason for this, I would appreciate it if they could give me some advice. Thank you very much!

1. The inside of the machine is quite dirty. 2. High temperatures cause the oil to carbonize. 3. Next, check whether the quality of the oil is up to standard.

One more thing: it’s possible for the medium to leak and enter the fuel tank, causing the fuel to deteriorate.

It’s not clear what medium the compressor is compressing. In my opinion, a quality analysis of the lubricant that has turned black should be conducted to determine whether there is any compressed medium present in it.

Hello! Our company also has a diaphragm compressor from Beijing Jingcheng Environmental Protection, and we encounter a similar issue: the oil turns black very quickly. What do you find to be the cause of this? Is the oil temperature too high? Is it still caused by mechanical impurities? Looking for an answer?

The original poster isn’t being fair – so many people have asked, why don’t you answer? I think it’s probably the diaphragm that’s leaking

Please, the original poster, explain the cause of the malfunction; only by exchanging ideas can we all improve together.

There can’t be so many mechanical impurities. Is the diaphragm damaged?
