The doing work theory of the three-blade roots blower: two three-lobed rotors are organized in the cavity, and the
suction port and the discharge port are opened on both sides of the cavity. By way of the motion of a pair of
synchronous gears, the two rotors rotate in opposite directions 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
function of blowing.

Attribute of our roots blower:
one. Huge adjustment of the air quantity

The Application of the Roots Blower

Maintenance and inspection
(1) Check all fasteners and finding pins situations regardless of whether they are loosening.
(two) Often verify regardless of whether the leakage phenomenon of the physique.
(3) Pay consideration to lubrication, amount of grease and noises when operating,
figure out regardless of whether it functions underneath the needed circumstances.
(4) Lubricant & grease: The lubricant is for medium load industrial gear oil
(grade 220, kinematic viscosity of 198 ~ 242mm2 / s 40ºC, flash stage ≥ 200ºC)
The grease is butter (artificial lithium grease penetration 220-250, fall point ≥
190ºC). Exchange the lubricant and grease after 1st 200 several hours managing, and replace
once again following a moth operating. Later, substitute the lubricant and grease according to the
atmosphere and lubricant (grease) quality suggest a appropriate EPT for a few
months.
(5) Always check the inlet air filter, thoroughly clean or exchange the filter in time.
(six) Blower overload occasionally not right away shown, so spend consideration to
the ingestion and exhaust pressure, bearing temperature and the present enhance developments
of motor to decide no matter whether the blower operates normally
(seven) Just before disassembling the blower, the assembling relation and dimensions
should be recorded or calculated, make marks on parts to make certain the unique
requirements right after assembling.
(8) When newly equipment or overhaul, the oil tank ought to be cleaned ahead of use
and suggest exchange all grease following 8 several hours working.

Typical failure purpose and troubleshooting

No Failure Possible causes Elimination approaches
one Friction
between the
impeller
(1) Impurities on the impeller,
ensuing in the gap is too little
(two) Gear put on, resulting in a
big backlash
(3) The equipment is not effectively mounted,
can not preserve the impeller
synchronization
(four) Bearing use ensuing in
clearance rising.
(1) Remove dirt and verify
regardless of whether there is damage parts
(2) Change the gear gap, substitute
the gears if the equipment backlash is
better than the common 30% to
50%
(three)Re-assemble the gears, hold
the taper make contact with location is to 75%
(4)Exchange the bearing
two Collision
in between
impeller and
wall, the
impeller prime
and casing
(one) Installation hole is not proper
(two) running force is too
high, exceeding the specified
price
(three) Working temperature is too large
(four) Casing or base deformation,
positioning supporter failure
(five) Bearing axial spot is not excellent
(one) Adjust the gap
(2) Recognize leads to of
overloading, lowered the stress
to the specified price
(three) Check out the installation
precision and reduce the pipe
stress
(4) Check out and fix bearings,
and to make certain the clearance
(5)Relocation
three Temperature
way too substantial
(one) Oil in tank is also considerably, too
thick or too dirty
(two) Filter or silencer is blocked
(3)The force is higher than
the specified worth
(4)Excessive dress in of the
impeller, huge hole
(five)Inadequate ventilation, indoor
temperature is higher, ensuing in
inlet air’s substantial temperature
(6) The rotating velocity is as well lower,end result in the belt slipping.
(one)Reduce the oil degree or depend on
oil
(2)Get rid of of blocking objects
(3)Minimizing the strain by means of
the blower
(4)Repair its clearance
(5)Open vents to decrease space
temperature
(6) Boost pace to avoid the
belt slipping.
four Insufficient
movement
(1) The inlet filter is blocked
(two) Impeller use and the hole
will increase also considerably
(three) Belt slipping
(4) Huge imports pressure loss
(five) Pipeline ventilation leakage
(1) Clean the filter dust and
obstruction
(two) Fix the hole
(3)Tighten the belt and enhance
the number of belts
(4)Adjust the inlet pressure to the
specified value
(5) Check out and fix the pipeline
5 Oil leaking or
oil leaking
into the enclosure
(one)Higher tank position cause
leakage from the discharge port
(two) Seal put on, ensuing in shaft oil spills
(three) The strain is increased than
the specified worth

 
(1)Reduce the oil amount
(two)Substitute the seals
(three)Obvious the air vents, 2mm diameter faucet is fixed in the
middle chamber, open the faucet
under the wall
6 Irregular
vibration and
sounds
(one)Bearing clearance exceeds the
specified benefit or bearing dress in
(two) The equipment backlash is way too
massive, not in a restricted fixed
(3) The international objects and dust
triggered by the impeller and the
impeller, the impeller and the
housing collision
(4) the impeller shaft
deformation caused the collision
triggered by overload,
(5) Friction amongst the impeller
and the inlet housing induced by
overheating
(6) Unbalance of the impeller
induced by fouling or international
entire body
(7) Anchor bolts or other
fasteners are loosened

seat
(2)Reassemble gear and guarantee
backlash
(3)Cleansing blower, check out the
case is damaged
(4)Verify the back again stress, verify
the wheel and change hole
(five)Examine the filter and back again
strain, increase the gap
between the impeller inlet and the
casing
(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.
seven Motor
overload
(1)In contrast with the necessary
stress, the force difference
is huge that the back pressure or
the inlet force is substantial
(two) In contrast with the
gear specifications, blower
stream is also massive, so its strain
increases
(3)Inlet filter is blocked, or outlet
pipe is obstructed or blocked
(4) Collusion or friction (trapped)
rotating elements
(5) The oil amount is too higher
(six) Slim V-belt is overheat,
vibration is too big, or pulley
is way too tiny
(1) Reduce the force to the
specified price
(two) Exhaust the surplus gas into
the environment or decrease the
blower velocity
(three) Remove the obstructions
(4)Quickly shut down, check
the purpose
(five) Adjust the oil to the correct
degree
(six) Examine the belt rigidity, and
replaced it with massive diameter
pulley.
