The functioning basic principle of the a few-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 motion 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 fuel in the chamber is pushed to obtain the
function of blowing.

Function of our roots blower:
one. Huge adjustment of the air volume
two. Reduced Sound
3. Substantial effectiveness
4. Reduced energy cosumption
5. Extended time existence
6. Trustworthy running, straightforward upkeep,small footprint

The Software of the Roots Blower

Servicing and inspection
(1) Verify all fasteners and finding pins situations whether they are loosening.
(2) Usually check out whether or not the leakage phenomenon of the entire body.
(3) Pay interest to lubrication, sum of grease and noises when running,
figure out no matter whether it functions beneath the essential conditions.
(4) Lubricant & 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 (artificial lithium grease penetration 220-250, drop point ≥
190ºC). Replace the lubricant and grease after initial 200 hrs working, and exchange
yet again after a moth running. Later, exchange the lubricant and grease in accordance to the
setting and lubricant (grease) quality suggest a suited EPT for three
(5) Always check the inlet air filter, cleanse or exchange the filter in time.
(six) Blower overload often not right away exhibited, so shell out attention to
the consumption and exhaust pressure, bearing temperature and the existing improve trends
of motor to decide whether or not the blower functions normally
(seven) Ahead of disassembling the blower, the assembling relation and dimensions
must be recorded or measured, make marks on factors to make certain the authentic
demands after assembling.
(eight) When recently equipment or overhaul, the oil tank should be cleaned before use
and suggest replace all grease soon after 8 hours managing.

Frequent failure explanation and troubleshooting

No Failure Possible motives Elimination techniques
1 Friction
among the
(one) Impurities on the impeller,
resulting in the hole is as well small
(two) Equipment put on, ensuing in a
large backlash
(three) The gear is not nicely mounted,
can not sustain the impeller
(four) Bearing use resulting in
clearance increasing.
(one) Remove dust and examine
whether or not there is hurt components
(two) Adjust the gear hole, change
the gears if the gear backlash is
better than the average thirty% to
(3)Re-assemble the gears, preserve
the taper speak to location is to seventy five%
(four)Replace the bearing
two Collision
in between
impeller and
wall, the
impeller leading
and casing
(one) Set up gap is not appropriate
(two) operating strain is also
high, exceeding the specified
(3) Running temperature is as well substantial
(4) Casing or base deformation,
positioning fan failure
(5) Bearing axial location is not great
(one) Change the gap
(2) Determine brings about of
overloading, diminished the pressure
to the specified value
(3) Verify the set up
precision and reduce the pipe
(four) Examine and mend bearings,
and to make sure the clearance
three Temperature
way too higher
(1) Oil in tank is as well considerably, as well
thick or also soiled
(two) Filter or silencer is blocked
(3)The stress is increased than
the specified price
(four)Excessive put on of the
impeller, massive gap
(five)Inadequate air flow, indoor
temperature is substantial, ensuing in
inlet air’s substantial temperature
(six) The rotating speed is as well reduced,outcome in the belt slipping.
(one)Reduce the oil level or depend on
(2)Take away of blocking objects

casing, to make sure that the impeller
clearance perform
(seven) Tighten the anchor bolts and
leveling the foundation.
seven Motor
(one)When compared with the required
force, the force variation
is massive that the back again force or
the inlet pressure is substantial
(two) Compared with the
products requirements, blower
movement is way too big, so its strain
(three)Inlet filter is blocked, or outlet
pipe is obstructed or blocked
(4) Collusion or friction (trapped)
rotating elements
(five) The oil stage is way too large
(6) Slim V-belt is overheat,
