The operating principle 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 each sides of the cavity. By means of the action of a pair of
synchronous gears, the two rotors rotate in reverse 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.

Function of our roots blower:
1. Huge adjustment of the air quantity
2. Lower Sounds
three. Substantial effectiveness
4. Lower power cosumption
5. Prolonged time lifestyle
six. Dependable operating, simple routine maintenance,little footprint

The Software of the Roots Blower

Servicing and inspection
(one) Check all fasteners and locating pins problems no matter whether they are loosening.
(two) Often check out no matter whether the leakage phenomenon of the human body.
(3) Pay out attention to lubrication, amount of grease and noises when running,
figure out regardless of whether it performs beneath the needed situations.
(four) Lubricant & grease: The lubricant is for medium load industrial gear oil
(quality 220, kinematic viscosity of 198 ~ 242mm2 / s 40ºC, flash point ≥ 200ºC)
The grease is butter (synthetic lithium grease penetration 220-250, drop level ≥
190ºC). Change the lubricant and grease soon after 1st 200 hrs running, and substitute
once more right after a moth operating. Afterwards, substitute the lubricant and grease in accordance to the
environment and lubricant (grease) top quality propose a suitable EPT for 3
months.
(5) Often verify the inlet air filter, clear or change the filter in time.
(six) Blower overload often not immediately shown, so pay out interest to
the intake and exhaust stress, bearing temperature and the recent enhance tendencies
of motor to figure out whether the blower functions typically
(7) Just before disassembling the blower, the assembling relation and proportions
should be recorded or calculated, make marks on components to make certain the unique
specifications after assembling.
(eight) When recently device or overhaul, the oil tank ought to be cleaned prior to use
and suggest replace all grease right after 8 hrs managing.

Common failure reason and troubleshooting

No Failure Achievable motives Elimination techniques
one Friction
amongst the
impeller
(one) Impurities on the impeller,
resulting in the gap is way too small
(2) Gear use, resulting in a
massive backlash
(3) The gear is not effectively mounted,
can not sustain the impeller
synchronization
(4) Bearing dress in resulting in
clearance increasing.
(one) Take away dust and check
whether or not there is harm elements
(2) Change the gear gap, exchange
the gears if the gear backlash is
greater than the typical thirty% to
50%
(3)Re-assemble the gears, preserve
the taper get in touch with spot is to 75%
(four)Substitute the bearing
two Collision
between
impeller and
wall, the
impeller top
and casing
(one) Set up gap is not proper
(two) working force is also
substantial, exceeding the specified
benefit
(three) Operating temperature is as well substantial
(4) Casing or foundation deformation,
positioning enthusiast failure
(five) Bearing axial place is not good
(1) Change the hole
(2) Recognize triggers of
overloading, diminished the pressure
to the specified benefit
(3) Check the installation
precision and decrease the pipe
rigidity
(4) Examine and restore bearings,
and to make sure the clearance
(5)Relocation
3 Temperature
also substantial
(1) Oil in tank is also much, as well
thick or as well soiled
(2) Filter or silencer is blocked
(three)The stress is higher than
the specified value
(four)Excessive wear of the
impeller, big hole
(5)Inadequate ventilation, indoor
temperature is high, ensuing in
inlet air’s large temperature
(six) The rotating velocity is also minimal,consequence in the belt slipping.
(one)Lessen the oil stage or count on
oil
(2)Remove of blocking objects
(three)Lowering the stress by way of
the blower
(four)Restore its clearance
(five)Open vents to minimize place
temperature
(6) Improve pace to stop the
belt slipping.
four Inadequate
circulation
(one) The inlet filter is blocked
(two) Impeller put on and the gap
boosts also considerably
(three) Belt slipping
(four) Huge imports strain loss
(5) Pipeline ventilation leakage
(one) Clean the filter dust and
obstruction
(2) Repair the gap
(3)Tighten the belt and boost
the amount of belts
(4)Change the inlet stress to the
specified value
(5) Check out and restore the pipeline
five Oil leaking or
oil leaking
into the enclosure
(1)Substantial tank position result in
leakage from the discharge port
(two) Seal wear, resulting in shaft oil spills
(3) The force is increased than
the specified value

 
(one)Decrease the oil degree
(two)Substitute the seals
(three)Very clear the air vents, 2mm diameter faucet is fastened in the
center chamber, open up the faucet
underneath the wall
six Irregular
vibration and
noise
(one)Bearing clearance exceeds the
specified benefit or bearing dress in
(2) The equipment backlash is as well
massive, not in a tight fastened
(three) The international objects and dust
brought on by the impeller and the
impeller, the impeller and the
housing collision
(four) the impeller shaft
deformation caused the collision
brought on by overload,
(5) Friction amongst the impeller
and the inlet housing triggered by
overheating
(6) Unbalance of the impeller
caused by fouling or overseas
body
(seven) Anchor bolts or other
fasteners are loosened
(1)Replace bearings or bearing
seat
(two)Reassemble gear and ensure
backlash
(3)Cleaning blower, examine the
scenario is ruined
(four)Verify the again force, check out
the wheel and adjust gap
(5)Check out the filter and back
stress, boost the hole
in between 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.
seven Motor
overload
(one)In comparison with the necessary
stress, the strain variation
is large that the back pressure or
the inlet stress is substantial
(2) When compared with the
tools demands, blower
movement is way too big, so its force
will increase
(three)Inlet filter is blocked, or outlet
pipe is obstructed or blocked
(4) Collusion or friction (stuck)
rotating elements
(5) The oil degree is way too large
(6) Narrow V-belt is overheat,
vibration is also huge, or pulley
is too tiny
(1) Decrease the force to the
specified value
(2) Exhaust the extra fuel into
the ambiance or minimize the
blower speed
(three) Take away the obstructions
(four)Right away shut down, check
the reason
(5) Change the oil to the appropriate
stage
(six) Examine the belt stress, and
replaced it with large diameter
pulley.
