The functioning theory of the 3-blade roots blower: two a few-lobed rotors are organized in the cavity, and the
suction port and the discharge port are opened on the two sides of the cavity. Via the action of a pair of
synchronous gears, the two rotors rotate in reverse instructions and Relying on the mutual engagement of the two
rotors, the suction port and the discharge port are isolated, and the fuel in the chamber is pushed to accomplish the
function of blowing.

The grease is butter (synthetic lithium grease penetration 220-250, drop position ≥
190ºC). Exchange the lubricant and grease soon after 1st 200 hours managing, and replace
once more following a moth operating. Later, exchange the lubricant and grease in accordance to the
surroundings and lubricant (grease) top quality propose a suited EPT for a few
(5) Often examine the inlet air filter, clear or replace the filter in time.
(6) Blower overload at times not right away exhibited, so pay focus to
the ingestion and exhaust stress, bearing temperature and the existing improve developments
of motor to determine whether or not the blower performs typically
(7) Before disassembling the blower, the assembling relation and dimensions
need to be recorded or measured, make marks on components to make certain the unique
needs soon after assembling.
(8) When recently device or overhaul, the oil tank should be cleaned ahead of use
and propose change all grease right after eight hours working.
