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 equally 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 attain the
goal of blowing.

Function of our roots blower:
1. Huge adjustment of the air volume
two. Minimal Noise
three. Substantial performance
4. Minimal vitality cosumption
5. Prolonged time life
six. Trustworthy running, straightforward servicing,little footprint

         Doosn Horzitonal Device Heart

The Application of the Roots Blower

Servicing and inspection
(one) Verify all fasteners and finding pins conditions no matter whether they are loosening.
(2) Usually check out whether or not the leakage phenomenon of the physique.
(3) Shell out interest to lubrication, volume of grease and noises when running,
figure out no matter whether it works below the needed circumstances.
(four) Lubricant & grease: The lubricant is for medium load industrial gear oil
(grade 220, kinematic viscosity of 198 ~ 242mm2 / s 40ºC, flash level ≥ 200ºC)
The grease is butter (synthetic lithium grease penetration 220-250, drop position ≥
190ºC). Exchange the lubricant and grease following first two hundred hrs managing, and change
yet again right after a moth working. Afterwards, replace the lubricant and grease according to the
atmosphere and lubricant (grease) top quality propose a suitable EPT for a few
months.
(five) Always check out the inlet air filter, cleanse or exchange the filter in time.
(six) Blower overload sometimes not instantly shown, so spend interest to
the consumption and exhaust strain, bearing temperature and the current improve tendencies
of motor to establish whether the blower operates generally
(7) Ahead of disassembling the blower, the assembling relation and proportions
need to be recorded or measured, make marks on factors to make certain the authentic
demands soon after assembling.
(8) When recently device or overhaul, the oil tank must be cleaned ahead of use
and suggest exchange all grease soon after eight hrs operating.

Typical failure purpose and troubleshooting

No Failure Attainable motives Elimination approaches
1 Friction
amongst the
impeller
(one) Impurities on the impeller,
resulting in the hole is as well small
(2) Gear wear, ensuing in a
big backlash
(3) The gear is not nicely mounted,
can not preserve the impeller
synchronization
(four) Bearing wear resulting in
clearance escalating.
(1) Get rid of dirt and verify
whether there is damage areas
(two) Change the equipment hole, replace
the gears if the gear backlash is
increased than the regular thirty% to
fifty%
(three)Re-assemble the gears, maintain
the taper get in touch with spot is to 75%
(4)Change the bearing
two Collision
between
impeller and
wall, the
impeller best
and casing
(one) Installation gap is not correct
(2) operating force is as well
higher, exceeding the specified
price
(3) Functioning temperature is way too high
(four) Casing or base deformation,
positioning admirer failure
(five) Bearing axial area is not great
(1) Modify the gap
(two) Recognize brings about of
overloading, lowered the strain
to the specified price
(three) Examine the installation
accuracy and reduce the pipe
tension
(four) Verify and mend bearings,
and to make certain the clearance
(5)Relocation
3 Temperature
way too high
(one) Oil in tank is as well much, too
thick or too soiled
(two) Filter or silencer is blocked
(3)The pressure is larger than
the specified benefit
(4)Abnormal put on of the
impeller, big hole
(5)Bad air flow, indoor
temperature is higher, ensuing in
inlet air’s high temperature
(6) The rotating pace is way too reduced,end result in the belt slipping.
(one)Reduce the oil stage or rely on
oil
(2)Take away of blocking objects
(three)Reducing the force via
the blower
(4)Repair its clearance
(five)Open up vents to lessen room
temperature
(6) Increase pace to avoid the
belt slipping.
four Inadequate
flow
(1) The inlet filter is blocked
(two) Impeller dress in and the hole
raises also significantly
(3) Belt slipping
(4) Huge imports stress loss
(5) Pipeline air flow leakage
(one) Clean the filter dust and
obstruction
(two) Restore the hole
(3)Tighten the belt and increase
the variety of belts
(4)Change the inlet pressure to the
specified benefit
(5) Examine and repair the pipeline
five Oil leaking or
oil leaking
into the enclosure
(one)High tank placement cause
leakage from the discharge port
(two) Seal dress in, resulting in shaft oil spills
(3) The pressure is higher than
the specified price

 
(one)Reduce the oil level
(2)Change the seals
(3)Obvious the air vents, 2mm diameter faucet is mounted in the
middle chamber, open the faucet
under the wall
6 Abnormal
vibration and
sounds
(1)Bearing clearance exceeds the
specified worth or bearing put on
(2) The equipment backlash is too
huge, not in a tight fastened
(3) The international objects and dust
induced by the impeller and the
impeller, the impeller and the
housing collision
(4) the impeller shaft
deformation brought on the collision
induced by overload,
(five) Friction amongst the impeller
and the inlet housing caused by
overheating
(6) Unbalance of the impeller
triggered by fouling or overseas
entire body
(seven) Anchor bolts or other
fasteners are loosened

seat
(2)Reassemble gear and guarantee
backlash
(3)Cleaning blower, examine the
situation is damaged
(four)Examine the again strain, verify
the wheel and adjust hole
(five)Examine the filter and back
strain, increase the gap
amongst the impeller inlet and the
casing
(6)Thoroughly clean the impeller and the
casing, to guarantee that the impeller
clearance work
(7) Tighten the anchor bolts and
leveling the foundation.
7 Motor
overload
(1)Compared with the necessary
force, the pressure distinction
is huge that the back force or
the inlet strain is substantial
(two) When compared with the
products requirements, blower
flow is way too large, so its force
increases
(3)Inlet filter is blocked, or outlet
pipe is obstructed or blocked
(4) Collusion or friction (stuck)
rotating elements
(five) The oil stage is as well higher
(6) Slim V-belt is overheat,
vibration is also big, or pulley
is also tiny
(1) Decrease the stress to the
specified price
(2) Exhaust the excess fuel into
the atmosphere or lessen the
blower pace
(3) Eliminate the obstructions
(four)Instantly shut down, check out
the cause
(5) Change the oil to the correct
level
(six) Examine the belt tension, and
replaced it with massive diameter
pulley.
