The working basic principle of the a few-blade roots blower: two a few-lobed rotors are organized in the cavity, and the
suction port and the discharge port are opened on the two sides of the cavity. Through the action of a pair of
synchronous gears, the two rotors rotate in reverse 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 attain the
purpose of blowing.

Attribute of our roots blower:
one. Large adjustment of the air quantity
two. Low Sounds
three. Large effectiveness
4. Minimal vitality cosumption
five. Long time daily life
six. Reliable operating, easy upkeep,small footprint

Our Roots Blower Workshop

         Doosn Horzitonal Device Heart

The Application of the Roots Blower

Servicing and inspection
(1) Verify all fasteners and finding pins problems no matter whether they are loosening.
(two) Often check whether the leakage phenomenon of the physique.
(3) Pay out interest to lubrication, quantity of grease and noises when managing,
figure out no matter whether it operates underneath the required problems.
(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 (synthetic lithium grease penetration 220-250, drop position ≥
190ºC). Replace the lubricant and grease after very first 200 hours working, and replace
once more soon after a moth managing. Afterwards, substitute the lubricant and grease in accordance to the
environment and lubricant (grease) high quality suggest a appropriate EPT for 3
(5) Constantly check the inlet air filter, thoroughly clean or replace the filter in time.
(six) Blower overload often not immediately exhibited, so pay attention to
the intake and exhaust strain, bearing temperature and the existing boost developments
of motor to determine whether or not the blower works usually
(7) Just before disassembling the blower, the assembling relation and dimensions
must be recorded or calculated, make marks on parts to make sure the first
requirements soon after assembling.
(8) When freshly device or overhaul, the oil tank ought to be cleaned ahead of use
and suggest substitute all grease after 8 several hours working.

Widespread failure cause and troubleshooting

No Failure Possible factors Elimination approaches
one Friction
among the
(one) Impurities on the impeller,
resulting in the hole is too tiny
(two) Gear put on, ensuing in a
big backlash
(three) The gear is not properly fixed,
can not keep the impeller
(4) Bearing wear resulting in
clearance increasing.
(one) Remove filth and verify
whether there is damage components
(2) Alter the gear hole, change
the gears if the gear backlash is
increased than the typical 30% to
(3)Re-assemble the gears, preserve
the taper get in touch with location is to 75%
(four)Change the bearing
2 Collision
impeller and
wall, the
impeller prime
and casing
(one) Installation hole is not appropriate
(2) functioning strain is also
higher, exceeding the specified
(three) Running temperature is too higher
(four) Casing or base deformation,
positioning enthusiast failure
(5) Bearing axial location is not excellent
(1) Modify the hole
(two) Discover triggers of
overloading, lowered the stress
to the specified value
(three) Examine the installation
accuracy and minimize the pipe
(4) Check out and restore bearings,
and to guarantee the clearance
three Temperature
as well large
(1) Oil in tank is way too much, way too
thick or way too dirty
(2) Filter or silencer is blocked
(three)The stress is increased than
the specified price
(4)Too much put on of the
impeller, huge hole
(5)Inadequate air flow, indoor
temperature is substantial, ensuing in
inlet air’s large temperature
(6) The rotating speed is way too minimal,result in the belt slipping.
(1)Minimize the oil degree or rely on
(2)Get rid of of blocking objects
(3)Decreasing the force via
the blower
(4)Fix its clearance
(5)Open up vents to lessen place
(6) Boost pace to avert the
belt slipping.
4 Insufficient
(1) The inlet filter is blocked
(two) Impeller use and the gap
will increase too a lot
(three) Belt slipping
(four) Large imports stress reduction
(5) Pipeline air flow leakage
(1) Clear the filter dust and
(two) Restore the hole
(three)Tighten the belt and improve
the variety of belts
(4)Modify the inlet pressure to the
specified benefit
(five) Verify and mend the pipeline
five Oil leaking or
oil leaking
into the enclosure
(one)Large tank place cause
leakage from the discharge port
(2) Seal use, resulting in shaft oil spills
(three) The pressure is greater than
the specified value

(one)Decrease the oil stage
(2)Change the seals
(3)Very clear the air vents, 2mm diameter faucet is set in the
middle chamber, open the faucet
underneath the wall
six Irregular
vibration and
(one)Bearing clearance exceeds the
specified price or bearing dress in
(2) The gear backlash is too
big, not in a tight fastened
(three) The overseas objects and dust
brought on by the impeller and the
impeller, the impeller and the
housing collision
(4) the impeller shaft
deformation triggered the collision
triggered by overload,
(five) Friction in between the impeller
and the inlet housing induced by
(6) Unbalance of the impeller
induced by fouling or international
(7) Anchor bolts or other
fasteners are loosened
(one)Substitute bearings or bearing
(2)Reassemble equipment and make certain
(3)Cleansing blower, check the
circumstance is ruined
(4)Examine the back again pressure, check
the wheel and modify hole
(5)Examine the filter and again
force, boost the gap
in between the impeller inlet and the
(6)Thoroughly clean the impeller and the
casing, to make certain that the impeller
clearance perform
(7) Tighten the anchor bolts and
leveling the foundation.
7 Motor
(1)In contrast with the necessary
stress, the strain big difference
is big that the back force or
the inlet strain is substantial
(2) Compared with the
equipment specifications, blower
circulation is also big, so its force
(three)Inlet filter is blocked, or outlet
pipe is obstructed or blocked
(4) Collusion or friction (trapped)
rotating components
(five) The oil amount is too substantial
(6) Slim V-belt is overheat,
vibration is as well massive, or pulley
is way too little
(1) Reduce the force to the
specified price
(two) Exhaust the excess gasoline into
the atmosphere or lessen the
blower speed
(3) Get rid of the obstructions
(4)Quickly shut down, check
the cause
(5) Alter the oil to the correct
(six) Examine the belt pressure, and
changed it with big diameter
