Principles for defining oil mist lubrication

Thread Content

The defining principle for using oil mist lubrication equipment in mechanical pumps is as follows: if the lubrication used is non-mandatory, then oil mist lubrication can be employed from a technical standpoint. Oil mist lubrication includes pure oil mist lubrication and purge-type oil mist lubrication, and these two types of lubrication can exist simultaneously in the same oil mist system. Pure oil mist lubrication is suitable for cantilever and double-supported centrifugal pumps with a pump power of less than 1000 Kw, a rotational speed of more than 600 revolutions per minute and less than 3000 revolutions per minute, and bearings that are not sleeve bearings or tapered roller bearings. The pump bearings are of the sliding bearing type; blow-through oil mist lubrication is used when the medium temperature is above 340°C and the pump body temperature is above 80°C. API is a standard set by the American Petroleum Institute; it was initially used primarily in equipment for the oil, petrochemical, and natural gas industries. Since the content covered by this standard is based on sound engineering validation and operational practices, products that comply with it offer significant advantages such as stable operation, long service life, and ease of installation and maintenance. As a result, it is now widely used in equipment for important applications and critical environments both domestically and internationally (such as key pumps in the petroleum, chemical, coal chemical, thermal power plant, and nuclear power industries). API610 is the standard for centrifugal pumps used in the oil, petrochemical, and natural gas industries. The key features of API610 standards are high reliability, long service life, ease of operation, and simplicity in installation and maintenance.
