Abstract: The basic philosophy of oil-mist lubrication is introduced, the differences between purge oil-mist lubrication and pure oil-mist lubrication in terms of configuration and structure are discussed, and the different application conditions of the two oil-mist lubrication methods in engineering are analyzed in detail. The key points of design for transforming the lubrication method of the existing pumps into purge oil-mist lubrication and pure oil-mist lubrication are put forward respectively. It is concluded that purge oil-mist lubrication can be chosen preferably according to the transformation conditions, so as to enhance the mechanical reliability and reduce the transformation difficulty. Finally, relevant requirements of the piping design of oil-mist lubrication are introduced.

Key words: purge oil-mist lubrication, pure oil-mist lubrication, transformation
