decide regardless of whether it works under the needed conditions.
(4) Lubricant & grease: The lubricant is for medium load industrial gear oil
(quality 220, kinematic viscosity of 198 ~ 242mm2 / s 40ºC, flash point ≥ 200ºC)
The grease is butter (synthetic lithium grease penetration 220-250, fall point ≥
190ºC). Replace the lubricant and grease following first 200 hrs operating, and replace
yet again soon after a moth running. Afterwards, replace the lubricant and grease according to the
atmosphere and lubricant (grease) high quality suggest a suited EPT for three
(5) Usually verify the inlet air filter, thoroughly clean or exchange the filter in time.
(6) Blower overload at times not quickly exhibited, so shell out consideration to
the ingestion and exhaust force, bearing temperature and the existing improve tendencies
of motor to figure out whether or not the blower operates usually
(seven) Just before disassembling the blower, the assembling relation and proportions
should be recorded or calculated, make marks on elements to make certain the original
needs after assembling.
(eight) When newly equipment or overhaul, the oil tank should be cleaned ahead of use
and propose substitute all grease soon after 8 hrs operating.
