The operating principle of the three-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. By way of 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 gas in the chamber is pushed to obtain the
purpose of blowing.

Characteristic of our roots blower:
one. Massive adjustment of the air quantity
2. Reduced Sound
three. Large performance
4. Reduced strength cosumption
five. Lengthy time life
6. Reliable working, effortless upkeep,modest footprint

Our Roots Blower Workshop

         Doosn Horzitonal Equipment Heart

The Application of the Roots Blower

Routine maintenance and inspection
(one) Check out all fasteners and finding pins circumstances regardless of whether they are loosening.
(two) Constantly verify no matter whether the leakage phenomenon of the human body.
(three) Spend interest to lubrication, sum of grease and noises when running,
decide whether or not it functions under the necessary conditions.
(4) Lubricant & grease: The lubricant is for medium load industrial equipment oil
(grade 220, kinematic viscosity of 198 ~ 242mm2 / s 40ºC, flash level ≥ 200ºC)
The grease is butter (artificial lithium grease penetration 220-250, drop position ≥
190ºC). Exchange the lubricant and grease after very first two hundred several hours working, and exchange
again soon after a moth managing. Later on, replace the lubricant and grease in accordance to the
surroundings and lubricant (grease) high quality propose a appropriate EPT for a few
months.
(five) Constantly check the inlet air filter, cleanse or change the filter in time.
(six) Blower overload sometimes not quickly exhibited, so spend attention to
the consumption and exhaust strain, bearing temperature and the recent increase trends
of motor to figure out whether or not the blower performs typically
(seven) Before disassembling the blower, the assembling relation and proportions
need to be recorded or calculated, make marks on parts to make certain the authentic
requirements after assembling.
(8) When recently device or overhaul, the oil tank ought to be cleaned just before use
and suggest substitute all grease right after 8 hrs working.

Frequent failure cause and troubleshooting

No Failure Feasible motives Elimination approaches
1 Friction
among the
impeller
(1) Impurities on the impeller,
ensuing in the hole is way too tiny
(2) Equipment wear, resulting in a
huge backlash
(three) The gear is not properly set,
can not maintain the impeller
synchronization
(4) Bearing put on resulting in
clearance rising.
(one) Remove filth and check out
whether there is harm areas
(two) Modify the gear gap, exchange
the gears if the gear backlash is
higher than the regular 30% to
50%
(3)Re-assemble the gears, keep
the taper make contact with region is to seventy five%
(four)Substitute the bearing
2 Collision
in between
impeller and
wall, the
impeller best
and casing
(1) Set up gap is not appropriate
(2) functioning pressure is as well
high, exceeding the specified
value
(3) Operating temperature is as well higher
(4) Casing or base deformation,
positioning supporter failure
(five) Bearing axial spot is not very good
(1) Adjust the hole
(two) Recognize triggers of
overloading, lowered the force
to the specified worth
(3) Check out the installation
precision and decrease the pipe
stress
(four) Check and repair bearings,
and to make sure the clearance
(five)Relocation
3 Temperature
also large
(1) Oil in tank is too much, also
thick or also soiled
(two) Filter or silencer is blocked
(3)The pressure is increased than
the specified price
(four)Excessive use of the
impeller, massive gap
(five)Inadequate ventilation, indoor
temperature is large, ensuing in
inlet air’s higher temperature
(6) The rotating velocity is also lower,end result in the belt slipping.
(1)Minimize the oil stage or depend on
oil
(2)Remove of blocking objects
(three)Minimizing the strain through
the blower
(four)Mend its clearance
(five)Open vents to reduce area
temperature
(6) Enhance pace to avert the
belt slipping.
four Insufficient
circulation
(one) The inlet filter is blocked
(two) Impeller dress in and the gap
boosts way too a lot
(3) Belt slipping
(four) Huge imports stress loss
(five) Pipeline ventilation leakage
(1) Clean the filter dust and
obstruction
(two) Restore the gap
(three)Tighten the belt and boost
the number of belts
(4)Alter the inlet pressure to the
specified value
(five) Check and mend the pipeline
5 Oil leaking or
oil leaking
into the enclosure
(1)Higher tank place cause
leakage from the discharge port
(two) Seal put on, ensuing in shaft oil spills
(3) The strain is larger than
the specified benefit

 
(one)Decrease the oil degree
(two)Replace the seals
(three)Distinct the air vents, 2mm diameter faucet is fastened in the
middle chamber, open up the faucet
under the wall
six Abnormal
vibration and
noise
(one)Bearing clearance exceeds the
specified price or bearing wear
(two) The gear backlash is also
massive, not in a tight set
(three) The overseas objects and dust
caused by the impeller and the
impeller, the impeller and the
housing collision
(four) the impeller shaft
deformation brought on the collision
triggered by overload,
(5) Friction among the impeller
and the inlet housing brought on by
overheating
(6) Unbalance of the impeller
brought on by fouling or international
body
(7) Anchor bolts or other
fasteners are loosened
(one)Change bearings or bearing
seat
(2)Reassemble equipment and make sure
backlash
(3)Cleansing blower, examine the
circumstance is destroyed
(four)Verify the again pressure, check
the wheel and change hole
(5)Examine the filter and again
pressure, increase the hole
between the impeller inlet and the
casing
(six)Thoroughly clean the impeller and the
casing, to make certain that the impeller
clearance operate
(seven) Tighten the anchor bolts and
leveling the foundation.
7 Motor
overload
(one)Compared with the essential
strain, the strain difference
is huge that the back force or
the inlet strain is large
(2) In comparison with the
products demands, blower
movement is as well massive, so its force
will increase
(3)Inlet filter is blocked, or outlet
pipe is obstructed or blocked
(four) Collusion or friction (stuck)
rotating parts
(5) The oil level is as well large
(six) Narrow V-belt is overheat,
vibration is too huge, or pulley
is too small
(one) Reduce the pressure to the
specified price
(2) Exhaust the excess fuel into
the atmosphere or reduce the
blower pace
(three) Get rid of the obstructions
(four)Immediately shut down, examine
the purpose
(5) Alter the oil to the correct
amount
(six) Check out the belt stress, and
replaced it with huge diameter
pulley.
