The functioning theory of the a few-blade roots blower: two three-lobed rotors are arranged in the cavity, and the
suction port and the discharge port are opened on the two sides of the cavity. Through the motion of a pair of
synchronous gears, the two rotors rotate in reverse instructions 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 obtain the
goal of blowing.

Characteristic of our roots blower:
one. Massive adjustment of the air volume
2. Low Sounds
3. Substantial performance
4. Reduced strength cosumption
5. Extended time life
6. Dependable working, simple routine maintenance,small footprint

The Application of the Roots Blower

Servicing and inspection
(1) Check all fasteners and finding pins problems no matter whether they are loosening.
(two) Often check whether the leakage phenomenon of the physique.
(three) Pay attention to lubrication, amount of grease and noises when running,
decide whether it works beneath the essential conditions.
(four) Lubricant & grease: The lubricant is for medium load industrial equipment oil
(grade 220, kinematic viscosity of 198 ~ 242mm2 / s 40ºC, flash stage ≥ 200ºC)
The grease is butter (artificial lithium grease penetration 220-250, drop stage ≥
190ºC). Exchange the lubricant and grease soon after first 200 several hours running, and substitute
once more right after a moth running. Later on, substitute the lubricant and grease in accordance to the
setting and lubricant (grease) good quality suggest a suited EPT for 3
months.
(five) Often check out the inlet air filter, clear or substitute the filter in time.
(6) Blower overload sometimes not right away shown, so pay out focus to
the consumption and exhaust strain, bearing temperature and the present boost traits
of motor to determine regardless of whether the blower operates generally
(7) Ahead of disassembling the blower, the assembling relation and proportions
need to be recorded or measured, make marks on components to make certain the authentic
requirements right after assembling.
(eight) When freshly device or overhaul, the oil tank need to be cleaned just before use
and propose replace all grease after 8 several hours managing.

Common failure explanation and troubleshooting

No Failure Feasible motives Elimination approaches
one Friction
in between the
impeller
(1) Impurities on the impeller,
resulting in the gap is too little
(2) Gear put on, resulting in a
huge backlash
(3) The equipment is not properly mounted,
can not preserve the impeller
synchronization
(four) Bearing use resulting in
clearance rising.
(1) Remove grime and check out
regardless of whether there is hurt components
(two) Change the equipment gap, exchange
the gears if the equipment backlash is
increased than the regular 30% to
50%
(three)Re-assemble the gears, keep
the taper get in touch with location is to seventy five%
(4)Substitute the bearing
two Collision
among
impeller and
wall, the
impeller best
and casing
(one) Set up hole is not appropriate
(two) operating stress is also
substantial, exceeding the specified
price
(three) Operating temperature is way too substantial
(four) Casing or base deformation,
positioning enthusiast failure
(5) Bearing axial place is not excellent
(one) Modify the hole
(2) Discover causes of
overloading, decreased the strain
to the specified price
(3) Verify the installation
accuracy and minimize the pipe
rigidity
(four) Check out and mend bearings,
and to make certain the clearance
(5)Relocation
three Temperature
as well substantial
(1) Oil in tank is too significantly, also
thick or too soiled
(two) Filter or silencer is blocked
(3)The strain is greater than
the specified benefit
(4)Abnormal wear of the
impeller, large hole
(five)Bad ventilation, indoor
temperature is substantial, resulting in
inlet air’s substantial temperature
(six) The rotating speed is way too lower,end result in the belt slipping.
(1)Reduce the oil stage or depend on
oil
(two)Get rid of of blocking objects
(3)Minimizing the pressure by way of
the blower
(4)Restore its clearance
(5)Open up vents to decrease area
temperature
(6) Improve speed to avoid the
belt slipping.
four Inadequate
circulation
(one) The inlet filter is blocked
(two) Impeller use and the gap
raises as well much
(3) Belt slipping
(4) Large imports pressure decline
(five) Pipeline air flow leakage
(1) Clean the filter dust and
obstruction
(2) Repair the hole
(three)Tighten the belt and enhance
the amount of belts
(four)Alter the inlet strain to the
specified benefit
(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 use, resulting in shaft oil spills
(3) The strain is increased than
the specified price

 
(one)Decrease the oil level
(two)Exchange the seals
(3)Very clear the air vents, 2mm diameter faucet is fixed in the
middle chamber, open up the faucet
under the wall
6 Abnormal
vibration and
sound
(one)Bearing clearance exceeds the
specified benefit or bearing use
(2) The equipment backlash is as well
huge, not in a limited set
(3) The foreign objects and dust
induced by the impeller and the
impeller, the impeller and the
housing collision
(4) the impeller shaft
deformation caused the collision
brought on by overload,
(five) Friction amongst the impeller
and the inlet housing brought on by
overheating
(6) Unbalance of the impeller
induced by fouling or overseas
body
(7) Anchor bolts or other
fasteners are loosened
(1)Substitute bearings or bearing
seat
(2)Reassemble gear and make certain
backlash
(3)Cleansing blower, check the
scenario is broken
(4)Examine the back force, check
the wheel and change gap
(5)Examine the filter and back again
strain, boost the gap
in between the impeller inlet and the
casing
(6)Thoroughly clean the impeller and the
casing, to make certain that the impeller
clearance operate
(seven) Tighten the anchor bolts and
leveling the base.
seven Motor
overload
(one)When compared with the required
strain, the force distinction
is massive that the back again stress or
the inlet pressure is high
(2) In comparison with the
equipment demands, blower
flow is as well big, so its stress
boosts
(3)Inlet filter is blocked, or outlet
pipe is obstructed or blocked
(4) Collusion or friction (caught)
rotating areas
(five) The oil stage is also high
(six) Slim V-belt is overheat,
vibration is way too massive, or pulley
is also small
(1) Minimize the strain to the
specified value
(2) Exhaust the surplus gasoline into
the atmosphere or minimize the
blower speed
(3) Take away the obstructions
(4)Immediately shut down, examine
the cause
(five) Change the oil to the appropriate
stage
(6) Verify the belt pressure, and
replaced it with big diameter
pulley.
