The Application of the Roots Blower
Servicing and inspection
(1) Examine all fasteners and finding pins situations regardless of whether they are loosening.
(two) Constantly check whether or not the leakage phenomenon of the physique.
(three) Pay out consideration to lubrication, quantity of grease and noises when running,
determine no matter whether it functions beneath the required conditions.
(4) CZPT & grease: The lubricant is for medium load industrial equipment oil
(quality 220, kinematic viscosity of 198 ~ 242mm2 / s 40ºC, flash point ≥ 200ºC)
The grease is butter (synthetic lithium grease penetration 220-250, fall position ≥
190ºC). Change the lubricant and grease following very first two hundred several hours managing, and change
once again right after a moth running. Afterwards, substitute the lubricant and grease in accordance to the
environment and lubricant (grease) high quality propose a appropriate alternative for 3
months.
(5) Constantly check out the inlet air filter, clean or substitute the filter in time.
(six) Blower overload occasionally not quickly shown, so pay attention to
the ingestion and exhaust pressure, bearing temperature and the present increase tendencies
of motor to figure out regardless of whether the blower functions normally
(7) Before disassembling the blower, the assembling relation and proportions
should be recorded or measured, make marks on parts to guarantee the CZPT
demands following assembling.
(8) When freshly machine or overhaul, the oil tank need to be cleaned just before use
and suggest change all grease right after eight hours operating.
