Reciprocating compressor oiler
Thread Content
Dear masters: I would like to ask what the oiling standards are for the oil injectors in reciprocating compressors. Are there any industry standards regarding this? Thank you.
Our 4M80 filler is oiled at 40 drops per minute
I haven’t seen the oiling standards, but I’ll share my experience from before; I hope it will be helpful to you. First, look at the cylinder diameter; generally, cylinders with a larger diameter have multiple oil injection points ； Another factor is pressure; when the pressure is low, the amount of oil to be injected can be appropriately reduced ； Finally, it is related to the operating temperature: the higher the operating temperature, the greater the amount of oil that needs to be injected. My previous requirement was 15–25 drops per minute for the low-pressure section, and 20–30 drops per minute for the high-pressure section; the filler material should be the same as that used in the cylinder body.
For our compressor’s oil injectors, about 5-7 drops are required at each of the two injection points; the filler has only one injection point and requires 10-15 drops. No specific standard seems to exist. Excessive oil injection into the cylinders is harmful to the equipment, and too much oil accumulating in the buffer tank needs to be drained regularly
There seems to be no fixed standard; in principle, as long as the compressor can operate safely and stably, the less oil is used, the better. Generally, one drop every four seconds is a suitable rate. Excessive oil injection not only leads to waste of oil but also puts pressure on various oil levels. If the waste oil is not removed in a timely manner, it can easily enter reactors such as synthesis towers, causing the catalyst to become poisoned and lose its effectiveness
It seems there is no fixed standard; each manufacturer calculates the losses based on the materials used and the temperature, etc., and can adjust them according to the actual conditions of use.
Thank you, sir. Our machines are relatively small, and in principle things are agreed upon verbally; the specified rate is 10–15 drops per minute. I was just wondering if there are any specific standards in this industry. Thank you.
Thank you, sir. Our machines are relatively small, and in principle the dosage is determined verbally – 10-15 drops per minute. I was just wondering if there are any specific standards in this industry. Your experience is very helpful to me, thank you.
Thank you, sir. In principle, we just communicate verbally here; there are no strict rules. Thank you.
Thank you, master. Your explanation was quite detailed and very helpful to me. Thank you. I think those who work with equipment know the standards well; if they don’t understand something, they can ask us and we can tell them what standards are being followed, which gives them more confidence. Now I know what’s going on, thanks.
Thank you, master. I just want to learn more on my own.
