The functioning 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 the two sides of the cavity. By means of the action of a pair of
synchronous gears, the two rotors rotate in reverse directions 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 achieve the
function of blowing.

The Software of the Roots Blower

Upkeep and inspection
(1) Verify all fasteners and finding pins problems no matter whether they are loosening.
(2) Often examine whether or not the leakage phenomenon of the entire body.
(3) Pay interest to lubrication, volume of grease and noises when operating,
decide whether or not it operates under the required conditions.
(4) Lubricant & grease: The lubricant is for medium load industrial equipment oil
(grade 220, kinematic viscosity of 198 ~ 242mm2 / s 40ºC, flash position ≥ 200ºC)
The grease is butter (artificial lithium grease penetration 220-250, fall stage ≥
190ºC). Replace the lubricant and grease following first 200 hours managing, and change
once again after a moth working. Later on, replace the lubricant and grease in accordance to the
atmosphere and lubricant (grease) good quality propose a suitable EPT for three
months.
(5) Constantly check the inlet air filter, cleanse or replace the filter in time.
(six) Blower overload occasionally not right away displayed, so spend focus to
the intake and exhaust pressure, bearing temperature and the current enhance traits
of motor to figure out whether or not the blower works usually
(seven) Just before disassembling the blower, the assembling relation and proportions
must be recorded or calculated, make marks on elements to make sure the first
requirements right after assembling.
(eight) When recently equipment or overhaul, the oil tank need to be cleaned before use
and suggest exchange all grease after 8 hours working.
