摘要

Reliability-focused readers know quite a bit about oil mist and many use plantwide oil mist systems for their process pumps and electric motor drivers. In fact, some major grassroots olefins plants used oil mist on motors with rolling-element bearings as small as 1 hp (0.75 kW) and as large as 1,250 hp (925 kW) as early as 1975- What's less known is that oil mist, together with the right viscosity synthetic lubricant, will save considerable energy.
