The operating theory of the 3-blade roots blower: two a few-lobed rotors are arranged 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 fuel in the chamber is pushed to accomplish the
purpose of blowing.

Function of our roots blower:
1. Massive adjustment of the air quantity
two. Low Noise
3. Higher effectiveness
4. Reduced power cosumption
five. Long time lifestyle
six. Reliable running, simple servicing,modest footprint

The Application of the Roots Blower

Servicing and inspection
(1) Examine all fasteners and finding pins circumstances regardless of whether they are loosening.
(two) Always examine regardless of whether the leakage phenomenon of the body.
(three) Pay focus to lubrication, amount of grease and noises when working,
establish no matter whether it operates below the needed conditions.
(four) 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 (artificial lithium grease penetration 220-250, drop stage ≥
190ºC). Replace the lubricant and grease after 1st two hundred hrs operating, and replace
once again following a moth working. Later, substitute the lubricant and grease according to the
setting and lubricant (grease) good quality suggest a appropriate EPT for 3
months.
(5) Often check the inlet air filter, clean or replace the filter in time.
(6) Blower overload at times not instantly exhibited, so shell out attention to
the ingestion and exhaust force, bearing temperature and the existing improve tendencies
of motor to figure out whether the blower performs normally
(7) Ahead of disassembling the blower, the assembling relation and dimensions
have to be recorded or calculated, make marks on factors to ensure the original
needs after assembling.
(8) When newly device or overhaul, the oil tank need to be cleaned ahead of use
and suggest exchange all grease right after 8 several hours managing.

Frequent failure cause and troubleshooting

No Failure Possible motives Elimination techniques
1 Friction
in between the
impeller
(1) Impurities on the impeller,
resulting in the gap is also tiny
(2) Gear use, resulting in a
large backlash
(3) The equipment is not well mounted,
can not maintain the impeller
synchronization
(four) Bearing dress in ensuing in
clearance increasing.
(1) Take away dirt and check out
regardless of whether there is harm areas
(2) Adjust the equipment hole, change
the gears if the equipment backlash is
greater than the typical 30% to
fifty%
(three)Re-assemble the gears, keep
the taper get in touch with spot is to 75%
(four)Replace the bearing
two Collision
between
impeller and
wall, the
impeller top
and casing
(1) Set up hole is not correct
(two) working pressure is too
high, exceeding the specified
value
(three) Functioning temperature is also large
(4) Casing or base deformation,
positioning admirer failure
(five) Bearing axial spot is not excellent
(one) Alter the hole
(2) Identify leads to of
overloading, lowered the pressure
to the specified price
(3) Check out the installation
precision and lessen the pipe
rigidity
(four) Check and restore bearings,
and to guarantee the clearance
(5)Relocation
three Temperature
way too large
(1) Oil in tank is way too much, way too
thick or as well soiled
(two) Filter or silencer is blocked
(three)The pressure is higher than
the specified value
(4)Too much dress in of the
impeller, huge gap
(5)Very poor air flow, indoor
temperature is substantial, ensuing in
inlet air’s substantial temperature
(six) The rotating velocity is as well lower,result in the belt slipping.
(one)Lessen the oil level or count on
oil
(2)Get rid of of blocking objects
(3)Decreasing the strain through
the blower
(four)Restore its clearance
(5)Open vents to lessen space
temperature
(six) Increase velocity to stop the
belt slipping.
4 Inadequate
circulation
(one) The inlet filter is blocked
(2) Impeller dress in and the gap
will increase as well much
(three) Belt slipping
(four) Massive imports pressure loss
(5) Pipeline air flow leakage
(one) Clear the filter dust and
obstruction
(two) Repair the hole
(three)Tighten the belt and boost
the variety of belts
(4)Change the inlet stress to the
specified price
(five) Check out and fix the pipeline
five Oil leaking or
oil leaking
into the enclosure
(one)Substantial tank place lead to
leakage from the discharge port
(2) Seal dress in, resulting in shaft oil spills
(three) The force is increased than
the specified benefit

 
(1)Minimize the oil stage
(two)Exchange the seals
(three)Very clear the air vents, 2mm diameter faucet is fixed in the
center chamber, open up the faucet
under the wall
6 Irregular
vibration and
sound
(one)Bearing clearance exceeds the
specified benefit or bearing dress in
(2) The equipment backlash is too
big, not in a tight mounted
(3) The international objects and dust
caused by the impeller and the
impeller, the impeller and the
housing collision
(4) the impeller shaft
deformation caused the collision
brought on by overload,
(5) Friction between the impeller
and the inlet housing induced by
overheating
(6) Unbalance of the impeller
caused by fouling or international
human body
(seven) Anchor bolts or other
fasteners are loosened
(1)Replace bearings or bearing
seat
(2)Reassemble gear and guarantee
backlash
(three)Cleansing blower, check the
case is damaged
(4)Examine the again stress, examine
the wheel and alter gap
(five)Verify the filter and back again
force, enhance the gap
in between the impeller inlet and the
casing
(6)Clean the impeller and the
casing, to guarantee that the impeller
clearance perform
(seven) Tighten the anchor bolts and
leveling the foundation.
7 Motor
overload
(one)In comparison with the essential
strain, the stress variation
is massive that the back again force or
the inlet strain is large
(2) When compared with the
equipment specifications, blower
movement is way too huge, so its strain
raises
(3)Inlet filter is blocked, or outlet
pipe is obstructed or blocked
(four) Collusion or friction (stuck)
rotating elements
(5) The oil amount is way too higher
(six) Slender V-belt is overheat,
vibration is also massive, or pulley
is also little
(1) Reduce the stress to the
specified benefit
(2) Exhaust the extra fuel into
the ambiance or decrease the
blower pace
(three) Get rid of the obstructions
(4)Right away shut down, examine
the explanation
(five) Modify the oil to the right
stage
(six) Check out the belt rigidity, and
replaced it with big diameter
pulley.
