The operating basic 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. Through 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 achieve the
goal of blowing.

Attribute of our roots blower:
1. Huge adjustment of the air volume
two. Reduced Sound

The Application of the Roots Blower

Routine maintenance and inspection
(1) Check out all fasteners and finding pins situations whether or not they are loosening.
(2) Constantly verify whether the leakage phenomenon of the entire body.
(three) Shell out consideration to lubrication, amount of grease and noises when running,
establish no matter whether it functions underneath the needed conditions.
(4) Lubricant & grease: The lubricant is for medium load industrial equipment oil
(quality 220, kinematic viscosity of 198 ~ 242mm2 / s 40ºC, flash position ≥ 200ºC)
The grease is butter (artificial lithium grease penetration 220-250, fall stage ≥
190ºC). Replace the lubricant and grease after 1st 200 several hours managing, and replace
again following a moth working. Afterwards, exchange the lubricant and grease in accordance to the
setting and lubricant (grease) high quality propose a suitable EPT for a few
months.
(five) Always examine the inlet air filter, clean or substitute the filter in time.
(six) Blower overload sometimes not right away exhibited, so pay out interest to
the ingestion and exhaust strain, bearing temperature and the existing improve developments
of motor to establish regardless of whether the blower operates generally
(7) Prior to disassembling the blower, the assembling relation and proportions
should be recorded or calculated, make marks on factors to guarantee the authentic
requirements soon after assembling.
(8) When recently device or overhaul, the oil tank must be cleaned before use
and suggest replace all grease following eight hrs working.

Frequent failure purpose and troubleshooting

No Failure Attainable reasons Elimination strategies
1 Friction
between the
impeller
(one) Impurities on the impeller,
resulting in the gap is also modest
(two) Equipment wear, resulting in a
big backlash
(3) The gear is not nicely fixed,
can not sustain the impeller
synchronization
(four) Bearing dress in resulting in
clearance rising.
(1) Eliminate grime and examine
regardless of whether there is hurt parts
(2) Change the gear gap, change
the gears if the gear backlash is
greater than the average thirty% to
fifty%
(3)Re-assemble the gears, maintain
the taper contact region is to seventy five%
(four)Change the bearing
2 Collision
between
impeller and
wall, the
impeller best
and casing
(one) Installation hole is not right
(two) functioning force is as well
substantial, exceeding the specified
price
(3) Functioning temperature is way too large
(4) Casing or foundation deformation,
positioning enthusiast failure
(five) Bearing axial spot is not good
(1) Adjust the gap
(2) Determine triggers of
overloading, diminished the pressure
to the specified worth
(3) Examine the set up
accuracy and decrease the pipe
rigidity
(four) Check out and mend bearings,
and to make certain the clearance
(5)Relocation
three Temperature
too large
(one) Oil in tank is as well significantly, also
thick or also filthy
(2) Filter or silencer is blocked
(3)The force is larger than
the specified price
(four)Excessive dress in of the
impeller, large gap
(five)Inadequate ventilation, indoor
temperature is large, resulting in
inlet air’s higher temperature
(6) The rotating speed is also reduced,result in the belt slipping.
(one)Minimize the oil degree or rely on
oil
(2)Get rid of of blocking objects
(three)Lowering the force via
the blower
(4)Fix its clearance
(five)Open up vents to minimize room
temperature
(six) Improve speed to avoid the
belt slipping.
four Inadequate
flow
(1) The inlet filter is blocked
(two) Impeller use and the hole
boosts as well much
(3) Belt slipping
(four) Huge imports strain loss
(five) Pipeline air flow leakage
(one) Clear the filter dust and
obstruction
(2) Mend the gap
(three)Tighten the belt and enhance
the variety of belts
(4)Modify the inlet pressure to the
specified value
(five) Verify and fix the pipeline
five Oil leaking or
oil leaking
into the enclosure
(1)Large tank situation trigger
leakage from the discharge port
(2) Seal wear, resulting in shaft oil spills
(three) The force is greater than
the specified value

 
(one)Reduce the oil level
(two)Replace the seals
(3)Distinct the air vents, 2mm diameter faucet is fixed in the
center chamber, open the faucet
underneath the wall
6 Irregular
vibration and
sounds
(1)Bearing clearance exceeds the
specified value or bearing wear
(two) The equipment backlash is too
massive, not in a tight mounted
(3) The overseas objects and dust
triggered by the impeller and the
impeller, the impeller and the
housing collision
(4) the impeller shaft
deformation brought on the collision
induced by overload,
(five) Friction in between the impeller
and the inlet housing induced by
overheating
(6) Unbalance of the impeller
caused by fouling or foreign
entire body
(7) Anchor bolts or other
fasteners are loosened
(one)Substitute bearings or bearing
seat
(2)Reassemble gear and ensure
backlash
(3)Cleansing blower, check the
circumstance is destroyed
(four)Examine the again force, examine
the wheel and change hole
(5)Check the filter and again
stress, improve the gap
amongst the impeller inlet and the
casing
(six)Cleanse the impeller and the
casing, to make sure that the impeller
clearance perform
(7) Tighten the anchor bolts and
leveling the base.
7 Motor
overload
(one)When compared with the needed
strain, the strain variation
is big that the back force or
the inlet stress is higher
(2) Compared with the
equipment specifications, blower
circulation is as well big, so its force
will increase
(3)Inlet filter is blocked, or outlet
pipe is obstructed or blocked
(four) Collusion or friction (trapped)
rotating components
(five) The oil degree is as well large
(6) Slender V-belt is overheat,
vibration is way too huge, or pulley
is way too little
(one) Decrease the stress to the
specified value
(two) Exhaust the excess gas into
the atmosphere or minimize the
blower speed
(3) Get rid of the obstructions
(four)Quickly shut down, verify
the purpose
(five) Modify the oil to the appropriate
degree
(6) Check out the belt tension, and
changed it with big diameter
pulley.
