The functioning principle of the 3-blade roots blower: two three-lobed rotors are organized in the cavity, and the
suction port and the discharge port are opened on each sides of the cavity. By way of 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 obtain the
purpose of blowing.

Feature of our roots blower:
1. Large adjustment of the air quantity
two. Lower Sound

Our Roots Blower Workshop

         Doosn Horzitonal Equipment Heart

The Application of the Roots Blower

Routine maintenance and inspection
(1) Check out all fasteners and finding pins circumstances whether they are loosening.
(two) Often check whether or not the leakage phenomenon of the entire body.
(3) Pay out consideration to lubrication, amount of grease and noises when managing,
decide no matter whether it functions under the needed problems.
(4) Lubricant & grease: The lubricant is for medium load industrial equipment oil
(grade 220, kinematic viscosity of 198 ~ 242mm2 / s 40ºC, flash position ≥ 200ºC)
The grease is butter (artificial lithium grease penetration 220-250, drop position ≥
190ºC). Change the lubricant and grease after 1st two hundred several hours managing, and exchange
once again right after a moth operating. Afterwards, change the lubricant and grease according to the
setting and lubricant (grease) good quality suggest a suitable EPT for three
months.
(5) Constantly verify the inlet air filter, thoroughly clean or change the filter in time.
(6) Blower overload at times not quickly exhibited, so spend consideration to
the consumption and exhaust force, bearing temperature and the present enhance trends
of motor to determine regardless of whether the blower works usually
(7) Prior to disassembling the blower, the assembling relation and dimensions
must be recorded or calculated, make marks on parts to ensure the unique
requirements soon after assembling.
(8) When recently equipment or overhaul, the oil tank ought to be cleaned just before use
and suggest change all grease following 8 several hours operating.

Typical failure reason and troubleshooting

No Failure Feasible reasons Elimination methods
one Friction
between the
impeller
(1) Impurities on the impeller,
resulting in the gap is as well small
(two) Equipment put on, resulting in a
huge backlash
(3) The equipment is not nicely mounted,
can not preserve the impeller
synchronization
(four) Bearing put on resulting in
clearance rising.
(1) Get rid of grime and check out
no matter whether there is harm parts
(2) Change the equipment gap, exchange
the gears if the equipment backlash is
better than the common 30% to
50%
(3)Re-assemble the gears, hold
the taper contact area is to seventy five%
(four)Exchange the bearing
two Collision
between
impeller and
wall, the
impeller top
and casing
(one) Installation hole is not appropriate
(two) running strain is as well
substantial, exceeding the specified
worth
(3) Working temperature is also higher
(four) Casing or base deformation,
positioning enthusiast failure
(five) Bearing axial place is not very good
(1) Modify the hole
(two) Recognize leads to of
overloading, diminished the force
to the specified value
(3) Verify the set up
accuracy and minimize the pipe
tension
(4) Check and restore bearings,
and to make certain the clearance
(five)Relocation
3 Temperature
too higher
(1) Oil in tank is way too much, way too
thick or way too filthy
(two) Filter or silencer is blocked
(3)The stress is greater than
the specified value
(four)Excessive use of the
impeller, massive gap
(5)Inadequate air flow, indoor
temperature is large, ensuing in
inlet air’s substantial temperature
(six) The rotating speed is as well reduced,end result in the belt slipping.
(one)Reduce the oil degree or rely on
oil
(two)Take away of blocking objects
(three)Reducing the strain by means of
the blower
(4)Fix its clearance
(five)Open up vents to reduce area
temperature
(6) Improve speed to avoid the
belt slipping.
four Insufficient
flow
(one) The inlet filter is blocked
(2) Impeller put on and the hole
increases also a lot
(3) Belt slipping
(4) Massive imports pressure loss
(five) Pipeline ventilation leakage
(1) Thoroughly clean the filter dust and
obstruction
(two) Mend the hole
(3)Tighten the belt and boost
the variety of belts
(four)Modify the inlet force to the
specified value
(five) Verify and restore the pipeline
five Oil leaking or
oil leaking
into the enclosure
(one)Higher tank placement result in
leakage from the discharge port
(2) Seal use, resulting in shaft oil spills
(3) The pressure is greater than
the specified price

 
(1)Lessen the oil degree
(2)Exchange the seals
(3)Very clear the air vents, 2mm diameter faucet is mounted in the
center chamber, open the faucet
below the wall
6 Irregular
vibration and
sound
(1)Bearing clearance exceeds the
specified value or bearing dress in
(2) The equipment backlash is too
huge, not in a tight fixed
(3) The foreign objects and dust
induced by the impeller and the
impeller, the impeller and the
housing collision
(four) the impeller shaft
deformation induced the collision
caused by overload,
(five) Friction in between the impeller
and the inlet housing brought on by
overheating
(6) Unbalance of the impeller
caused by fouling or overseas
physique
(7) Anchor bolts or other
fasteners are loosened
(one)Substitute bearings or bearing
seat
(two)Reassemble gear and make certain
backlash
(three)Cleaning blower, verify the
circumstance is damaged
(four)Check the again pressure, check out
the wheel and modify gap
(five)Verify the filter and back again
force, improve the gap
among the impeller inlet and the
casing
(six)Clear the impeller and the
casing, to make sure that the impeller
clearance work
(7) Tighten the anchor bolts and
leveling the base.
seven Motor
overload
(one)In contrast with the needed
force, the force difference
is huge that the back strain or
the inlet pressure is higher
(two) Compared with the
tools demands, blower
flow is also huge, so its force
raises
(3)Inlet filter is blocked, or outlet
pipe is obstructed or blocked
(four) Collusion or friction (trapped)
rotating components
(5) The oil level is as well higher
(six) Narrow V-belt is overheat,
vibration is as well large, or pulley
is as well tiny
(1) Decrease the pressure to the
specified price
(two) Exhaust the extra fuel into
the ambiance or reduce the
blower velocity
(3) Eliminate the obstructions
(four)Immediately shut down, check
the purpose
(five) Change the oil to the appropriate
amount
(six) Examine the belt stress, and
changed it with huge diameter
pulley.
