The functioning principle of the 3-blade roots blower: two 3-lobed rotors are organized in the cavity, and the
suction port and the discharge port are opened on each sides of the cavity. Through the action 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 gasoline in the chamber is pushed to achieve the
function of blowing.

Characteristic of our roots blower:
one. Huge adjustment of the air volume
two. Lower Sounds
3. Large effectiveness
4. Lower vitality cosumption
5. Extended time lifestyle
6. Dependable working, effortless routine maintenance,tiny footprint

Our Roots Blower Workshop

         Doosn Horzitonal Equipment Heart

The Application of the Roots Blower

Servicing and inspection
(one) Verify all fasteners and finding pins conditions whether or not they are loosening.
(2) Always check whether the leakage phenomenon of the physique.
(3) Pay consideration to lubrication, sum of grease and noises when operating,
decide regardless of whether it performs under the necessary problems.
(four) Lubricant & grease: The lubricant is for medium load industrial gear oil
(grade 220, kinematic viscosity of 198 ~ 242mm2 / s 40ºC, flash stage ≥ 200ºC)
The grease is butter (artificial lithium grease penetration 220-250, fall position ≥
190ºC). Change the lubricant and grease right after very first 200 hrs running, and exchange
yet again after a moth managing. Later, substitute the lubricant and grease in accordance to the
surroundings and lubricant (grease) high quality suggest a suited EPT for a few
months.
(5) Constantly verify the inlet air filter, clear or replace the filter in time.
(6) Blower overload occasionally not immediately exhibited, so shell out interest to
the intake and exhaust strain, bearing temperature and the current enhance developments
of motor to determine whether the blower functions normally
(7) Before disassembling the blower, the assembling relation and proportions
must be recorded or calculated, make marks on parts to make certain the unique
specifications following assembling.
(eight) When newly equipment or overhaul, the oil tank must be cleaned ahead of use
and propose replace all grease right after eight hours working.

Widespread failure cause and troubleshooting

No Failure Attainable causes Elimination methods
1 Friction
between the
impeller
(one) Impurities on the impeller,
ensuing in the hole is as well tiny
(2) Equipment use, ensuing in a
big backlash
(three) The equipment is not nicely set,
can not maintain the impeller
synchronization
(4) Bearing use ensuing in
clearance rising.
(1) Take away dust and check
whether or not there is harm parts
(two) Alter the gear hole, replace
the gears if the gear backlash is
increased than the typical 30% to
50%
(3)Re-assemble the gears, preserve
the taper contact area is to seventy five%
(four)Substitute the bearing
2 Collision
among
impeller and
wall, the
impeller leading
and casing
(1) Installation gap is not proper
(2) working stress is also
high, exceeding the specified
benefit
(3) Working temperature is also large
(4) Casing or base deformation,
positioning supporter failure
(five) Bearing axial place is not great
(1) Adjust the hole
(two) Identify leads to of
overloading, lowered the force
to the specified value
(3) Verify the set up
accuracy and minimize the pipe
tension
(4) Check out and restore bearings,
and to ensure the clearance
(five)Relocation
3 Temperature
too higher
(one) Oil in tank is too significantly, way too
thick or also filthy
(two) Filter or silencer is blocked
(three)The force is higher than
the specified value
(four)Abnormal dress in of the
impeller, massive hole
(five)Bad air flow, indoor
temperature is higher, resulting in
inlet air’s high temperature
(six) The rotating speed is too lower,consequence in the belt slipping.
(one)Lessen the oil degree or rely on
oil
(two)Remove of blocking objects
(3)Decreasing the force via
the blower
(four)Repair its clearance
(5)Open up vents to decrease space
temperature
(6) Improve velocity to avoid the
belt slipping.
four Insufficient
flow
(one) The inlet filter is blocked
(two) Impeller use and the gap
boosts as well a lot
(three) Belt slipping
(4) Massive imports strain decline
(five) Pipeline ventilation leakage
(one) Cleanse the filter dust and
obstruction
(2) Fix the gap
(3)Tighten the belt and increase
the amount of belts
(four)Adjust the inlet pressure to the
specified value
(five) Check and restore the pipeline
five Oil leaking or
oil leaking
into the enclosure
(one)Large tank place cause
leakage from the discharge port
(2) Seal wear, ensuing in shaft oil spills
(three) The stress is increased than
the specified benefit

 
(1)Lessen the oil stage
(two)Substitute the seals
(3)Obvious the air vents, 2mm diameter faucet is mounted in the
middle chamber, open up the faucet
underneath the wall
6 Abnormal
vibration and
sounds
(1)Bearing clearance exceeds the
specified value or bearing dress in
(two) The equipment backlash is also
massive, not in a restricted fixed
(3) The international objects and dust
induced by the impeller and the
impeller, the impeller and the
housing collision
(4) the impeller shaft
deformation triggered the collision
triggered by overload,
(5) Friction among the impeller
and the inlet housing triggered by
overheating
(6) Unbalance of the impeller
induced by fouling or international
human body
(seven) Anchor bolts or other
fasteners are loosened
(one)Change bearings or bearing
seat
(2)Reassemble equipment and guarantee
backlash
(three)Cleansing blower, check out the
situation is destroyed
(4)Verify the back again stress, verify
the wheel and adjust hole
(5)Examine the filter and back
stress, improve the gap
among the impeller inlet and the
casing
(6)Cleanse the impeller and the
casing, to ensure that the impeller
clearance work
(7) Tighten the anchor bolts and
leveling the foundation.
seven Motor
overload
(1)In contrast with the necessary
force, the strain difference
is large that the again stress or
the inlet strain is substantial
(2) In contrast with the
gear demands, blower
circulation is as well huge, so its stress
raises
(three)Inlet filter is blocked, or outlet
pipe is obstructed or blocked
(four) Collusion or friction (trapped)
rotating areas
(five) The oil stage is way too high
(six) Narrow V-belt is overheat,
vibration is as well large, or pulley
is too small
(1) Lessen the force to the
specified benefit
(2) Exhaust the surplus gas into
the ambiance or minimize the
blower speed
(3) Get rid of the obstructions
(4)Immediately shut down, verify
the reason
(5) Adjust the oil to the proper
amount
(6) Check out the belt rigidity, and
changed it with large diameter
pulley.
