The doing work 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. Via the motion of a pair of
synchronous gears, the two rotors rotate in opposite 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 achieve the
purpose of blowing.

Attribute of our roots blower:
one. Massive adjustment of the air quantity
two. Minimal Noise
3. Substantial performance
four. Lower energy cosumption
5. Long time existence
6. Reputable operating, straightforward servicing,little footprint

The Software of the Roots Blower

Routine maintenance and inspection
(1) Examine all fasteners and finding pins circumstances no matter whether they are loosening.
(2) Constantly verify whether or not the leakage phenomenon of the human body.
(3) Pay out interest to lubrication, volume of grease and noises when running,
figure out regardless of whether it performs under the required circumstances.
(four) Lubricant & grease: The lubricant is for medium load industrial equipment oil
(quality 220, kinematic viscosity of 198 ~ 242mm2 / s 40ºC, flash level ≥ 200ºC)
The grease is butter (synthetic lithium grease penetration 220-250, fall stage ≥
190ºC). Replace the lubricant and grease following 1st two hundred hrs operating, and exchange
again soon after a moth operating. Later, exchange the lubricant and grease according to the
surroundings and lubricant (grease) top quality suggest a suited EPT for three
months.
(five) Constantly check out the inlet air filter, clear or replace the filter in time.
(6) Blower overload sometimes not immediately displayed, so pay out interest to
the ingestion and exhaust pressure, bearing temperature and the current enhance traits
of motor to determine regardless of whether the blower performs typically
(7) Before disassembling the blower, the assembling relation and dimensions
have to be recorded or measured, make marks on components to ensure the first
specifications soon after assembling.
(eight) When recently machine or overhaul, the oil tank ought to be cleaned just before use
and propose exchange all grease right after eight hrs managing.

Typical failure purpose and troubleshooting

No Failure Achievable reasons Elimination techniques
1 Friction
amongst the
impeller
(1) Impurities on the impeller,
ensuing in the gap is as well small
(two) Equipment put on, resulting in a
huge backlash
(3) The gear is not effectively fixed,
can not sustain the impeller
synchronization
(four) Bearing put on ensuing in
clearance rising.
(1) Take away grime and check
no matter whether there is damage areas
(2) Adjust the gear hole, substitute
the gears if the equipment backlash is
better than the average 30% to
50%
(3)Re-assemble the gears, maintain
the taper contact location is to seventy five%
(four)Change the bearing
2 Collision
between
impeller and
wall, the
impeller best
and casing
(1) Set up hole is not correct
(two) running pressure is way too
substantial, exceeding the specified
value
(3) Working temperature is way too higher
(four) Casing or foundation deformation,
positioning admirer failure
(five) Bearing axial spot is not good
(one) Modify the hole
(two) Discover triggers of
overloading, reduced the pressure
to the specified value
(3) Examine the installation
accuracy and lessen the pipe
pressure
(4) Verify and mend bearings,
and to make sure the clearance
(five)Relocation
3 Temperature
also high
(1) Oil in tank is way too a lot, way too
thick or also dirty
(two) Filter or silencer is blocked
(three)The strain is increased than
the specified price
(four)Excessive wear of the
impeller, big hole
(five)Very poor ventilation, indoor
temperature is higher, ensuing in
inlet air’s high temperature
(six) The rotating speed is as well reduced,result in the belt slipping.
(one)Decrease the oil amount or rely on
oil
(two)Remove of blocking objects
(3)Decreasing the stress by means of
the blower
(four)Mend its clearance
(5)Open up vents to lessen room
temperature
(6) Improve pace to prevent the
belt slipping.
4 Insufficient
movement
(one) The inlet filter is blocked

obstruction
(two) Fix the gap
(three)Tighten the belt and enhance
the quantity of belts
(four)Modify the inlet pressure to the
specified value
(5) Verify and repair the pipeline
five Oil leaking or
oil leaking

center chamber, open the faucet
beneath the wall
six Irregular
vibration and
noise
(one)Bearing clearance exceeds the
specified price or bearing use
(2) The gear backlash is too
massive, not in a tight fastened
(three) The international objects and dust
induced by the impeller and the
impeller, the impeller and the
housing collision

the wheel and change gap
(5)Examine the filter and back
force, enhance the gap
among the impeller inlet and the
casing
(6)Thoroughly clean the impeller and the
casing, to ensure that the impeller
clearance work
(seven) Tighten the anchor bolts and
leveling the base.
7 Motor
overload
(one)In comparison with the needed
strain, the strain big difference
is big that the back pressure or
the inlet stress is substantial
(2) When compared with the
equipment specifications, blower
stream is as well large, so its stress
will increase
(three)Inlet filter is blocked, or outlet
pipe is obstructed or blocked
(4) Collusion or friction (caught)
rotating parts
(5) The oil degree is too substantial
(6) Slender V-belt is overheat,
vibration is as well massive, or pulley
is way too modest
(one) Lessen the stress to the
specified price
