The doing work theory of the three-blade roots blower: two a few-lobed rotors are arranged in the cavity, and the
suction port and the discharge port are opened on equally sides of the cavity. By means of the motion 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 gas in the chamber is pushed to obtain the
function of blowing.

Characteristic of our roots blower:
1. Large adjustment of the air volume
two. Lower Sound
3. Substantial efficiency
4. Low power cosumption
five. Long time existence
six. Dependable operating, easy maintenance,small footprint

Our Roots Blower Workshop

         Doosn Horzitonal Equipment Heart

The Application of the Roots Blower

Servicing and inspection
(1) Check out all fasteners and locating pins conditions whether they are loosening.
(two) Often verify whether or not the leakage phenomenon of the body.
(three) Shell out focus to lubrication, amount of grease and noises when managing,
establish whether it performs below the needed situations.
(4) Lubricant & grease: The lubricant is for medium load industrial gear oil
(quality 220, kinematic viscosity of 198 ~ 242mm2 / s 40ºC, flash stage ≥ 200ºC)
The grease is butter (synthetic lithium grease penetration 220-250, drop position ≥
190ºC). Exchange the lubricant and grease soon after very first two hundred hours managing, and substitute
once more right after a moth working. Afterwards, change the lubricant and grease in accordance to the
setting and lubricant (grease) good quality propose a suitable EPT for a few
months.
(five) Constantly examine the inlet air filter, thoroughly clean or change the filter in time.
(6) Blower overload occasionally not quickly exhibited, so pay attention to
the ingestion and exhaust force, bearing temperature and the recent improve trends
of motor to figure out whether the blower functions usually
(7) Prior to disassembling the blower, the assembling relation and dimensions
have to be recorded or measured, make marks on factors to make sure the unique
needs after assembling.
(eight) When newly machine or overhaul, the oil tank should be cleaned before use
and propose substitute all grease following eight several hours working.

Frequent failure explanation and troubleshooting

No Failure Feasible causes Elimination approaches
one Friction
in between the
impeller
(1) Impurities on the impeller,
ensuing in the gap is also tiny
(two) Gear use, ensuing in a
large backlash
(3) The gear is not effectively mounted,
can not maintain the impeller
synchronization
(4) Bearing dress in resulting in
clearance growing.
(1) Take away grime and check
regardless of whether there is hurt elements
(2) Alter the gear gap, exchange
the gears if the equipment backlash is
better than the regular 30% to
50%
(three)Re-assemble the gears, preserve
the taper make contact with spot is to seventy five%
(four)Exchange the bearing
two Collision
in between
impeller and
wall, the
impeller best
and casing
(one) Set up hole is not correct
(two) operating strain is way too
large, exceeding the specified
price
(3) Working temperature is as well higher
(4) Casing or base deformation,
positioning fan failure
(5) Bearing axial location is not excellent
(1) Adjust the hole
(two) Determine leads to of
overloading, diminished the strain
to the specified benefit
(three) Check out the installation
precision and lessen the pipe
pressure
(4) Verify and fix bearings,
and to make certain the clearance
(five)Relocation
3 Temperature
as well substantial
(one) Oil in tank is too considerably, too
thick or also dirty
(two) Filter or silencer is blocked
(3)The pressure is increased than
the specified benefit
(four)Too much wear of the
impeller, large gap
(five)Inadequate ventilation, indoor
temperature is substantial, ensuing in
inlet air’s large temperature
(six) The rotating pace is also low,outcome in the belt slipping.
(one)Reduce the oil amount or count on
oil
(two)Eliminate of blocking objects
(3)Reducing the strain via
the blower
(four)Restore its clearance
(5)Open vents to decrease room
temperature
(six) Increase velocity to prevent the
belt slipping.
4 Insufficient
movement
(1) The inlet filter is blocked
(2) Impeller dress in and the gap
boosts also a lot
(3) Belt slipping
(four) Large imports strain decline
(5) Pipeline air flow leakage
(one) Cleanse the filter dust and
obstruction
(two) Mend the gap
(3)Tighten the belt and boost
the variety of belts
(four)Alter the inlet force to the
specified value
(5) Check out and mend the pipeline
five Oil leaking or
oil leaking
into the enclosure
(one)Large tank position result in
leakage from the discharge port
(2) Seal dress in, resulting in shaft oil spills
(3) The strain is greater than
the specified value

 
(one)Decrease the oil stage
(two)Substitute the seals
(3)Distinct the air vents, 2mm diameter faucet is fastened 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 use
(2) The gear backlash is as well
large, not in a tight fastened
(3) The international objects and dust
triggered by the impeller and the
impeller, the impeller and the
housing collision
(4) the impeller shaft
deformation induced the collision
caused by overload,
(5) Friction amongst the impeller
and the inlet housing brought on by
overheating
(6) Unbalance of the impeller
induced by fouling or overseas
body
(7) Anchor bolts or other
fasteners are loosened
(one)Substitute bearings or bearing
seat
(two)Reassemble gear and make sure
backlash
(three)Cleansing blower, verify the
circumstance is ruined
(four)Examine the back again force, check
the wheel and adjust gap
(5)Verify the filter and back again
stress, enhance the gap
in between the impeller inlet and the
casing
(6)Cleanse the impeller and the
casing, to guarantee that the impeller
clearance operate
(seven) Tighten the anchor bolts and
leveling the base.
7 Motor
overload
(1)When compared with the required
pressure, the force big difference
is huge that the back again strain or
the inlet strain is high
(2) In contrast with the
tools needs, blower
circulation is too large, so its strain
raises
(three)Inlet filter is blocked, or outlet
pipe is obstructed or blocked
(4) Collusion or friction (stuck)
rotating parts
(5) The oil stage is also high
(six) Slender V-belt is overheat,
vibration is as well massive, or pulley
is as well modest
(one) Lessen the force to the
specified price
(two) Exhaust the excessive gas into
the environment or decrease the
blower pace
(3) Take away the obstructions
(4)Right away shut down, check out
the purpose
(five) Alter the oil to the proper
level
(six) Check out the belt tension, and
replaced it with large diameter
pulley.
