The operating principle of the 3-blade roots blower: two three-lobed rotors are arranged in the cavity, and the
suction port and the discharge port are opened on both sides of the cavity. By means of the action of a pair of
synchronous gears, the two rotors rotate in opposite directions and Relying on the mutual engagement of the two
rotors, the suction port and the discharge port are isolated, and the gas in the chamber is pushed to accomplish the
purpose of blowing.

The Software of the Roots Blower

Maintenance and inspection
(1) Check out all fasteners and finding pins circumstances whether they are loosening.
(2) Always check no matter whether the leakage phenomenon of the human body.
(three) Shell out focus to lubrication, amount of grease and noises when working,
figure out regardless of whether it operates below the needed situations.
(four) Lubricant & grease: The lubricant is for medium load industrial gear oil
(quality 220, kinematic viscosity of 198 ~ 242mm2 / s 40ºC, flash stage ≥ 200ºC)
The grease is butter (synthetic lithium grease penetration 220-250, fall position ≥
190ºC). Substitute the lubricant and grease following first two hundred hours working, and change
yet again right after a moth working. Afterwards, replace the lubricant and grease in accordance to the
surroundings and lubricant (grease) quality propose a suited EPT for three
(five) Usually check out the inlet air filter, clear or exchange the filter in time.
(6) Blower overload sometimes not immediately exhibited, so shell out focus to
the ingestion and exhaust stress, bearing temperature and the recent boost traits
of motor to figure out regardless of whether the blower works usually
(7) Prior to disassembling the blower, the assembling relation and proportions
have to be recorded or measured, make marks on factors to make sure the original
specifications following assembling.
(eight) When freshly device or overhaul, the oil tank must be cleaned before use
and suggest exchange all grease following 8 hrs managing.
