Questions regarding the selection of lubricants and greases.

How should lubricants be selected for reducers, centrifugal pumps, compressors, and vacuum pumps? For ordinary mechanical pumps, which type of lubricant can be used universally under such conditions? Which lubricants and gear oils should be chosen for summer and winter?
It’s difficult to answer such a question; you need to provide the exact device model and operating conditions so that I can analyze which type of oil is suitable
Agree with the person above. There’s one thing to clarify: are all your devices located outdoors? If the answer is no, then you’re overthinking it. If the answer is yes, the actual temperature difference will not be determined by this algorithm, as the device itself experiences a temperature rise while it is in operation.
Reply to 1# lm1986: I’m not sure where the original poster is located; in summer, the maximum temperature is around 40 degrees, and in winter it’s around 30 degrees. Such a small temperature difference?
Reply to 4# hcwang12345: -30 degrees, thank you.
Reply to 3# Youdai: Let’s mention a few models. The model of Friatec is RCNKU 150-125-315CST; the Kenney vacuum pump is model ZJ-702; the Hammett shielded electric pump is model CNF40-160; the diesel generator from Dongfeng Cummins has the model 6CTAA83-62; the RICHGER model is RMA-B-F15*1*6
It has nothing to do with what model of device it is; I’m asking you； Are all your devices outdoors? If the answer is no, then you’re overthinking it. If the answer is yes, the actual temperature difference will not be determined by this algorithm, as the device itself experiences a temperature rise while it is in operation.
