determine no matter whether it functions below the essential situations.
(four) Lubricant & grease: The lubricant is for medium load industrial equipment oil
(grade 220, kinematic viscosity of 198 ~ 242mm2 / s 40ºC, flash stage ≥ 200ºC)
The grease is butter (synthetic lithium grease penetration 220-250, drop level ≥
190ºC). Change the lubricant and grease soon after first 200 several hours running, and replace
again after a moth working. Later on, replace the lubricant and grease according to the
setting and lubricant (grease) good quality suggest a appropriate EPT for 3
(5) Always examine the inlet air filter, thoroughly clean or substitute the filter in time.
(6) Blower overload often not right away displayed, so pay consideration to
the consumption and exhaust pressure, bearing temperature and the current boost tendencies
of motor to decide no matter whether the blower functions generally
(7) Ahead of disassembling the blower, the assembling relation and dimensions
should be recorded or calculated, make marks on factors to ensure the original
needs soon after assembling.
(8) When recently equipment or overhaul, the oil tank should be cleaned prior to use
and propose change all grease soon after eight several hours working.
