The doing work basic principle of the three-blade roots blower: two 3-lobed rotors are organized in the cavity, and the
suction port and the discharge port are opened on each sides of the cavity. By means of the motion 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 gas in the chamber is pushed to attain the
objective of blowing.

Attribute of our roots blower:
1. Big adjustment of the air volume
2. Minimal Sound
three. Substantial effectiveness
four. Low power cosumption
5. Long time daily life
6. Dependable working, straightforward maintenance,modest footprint

The Software of the Roots Blower

Maintenance and inspection
(one) Check all fasteners and locating pins conditions regardless of whether they are loosening.
(two) Usually verify regardless of whether the leakage phenomenon of the body.
(3) Pay consideration to lubrication, volume of grease and noises when managing,
decide regardless of whether it works below the necessary circumstances.
(4) Lubricant & grease: The lubricant is for medium load industrial equipment oil
(grade 220, kinematic viscosity of 198 ~ 242mm2 / s 40ºC, flash level ≥ 200ºC)
The grease is butter (synthetic lithium grease penetration 220-250, drop position ≥
190ºC). Exchange the lubricant and grease soon after 1st two hundred several hours working, and change
once more right after a moth running. Afterwards, replace the lubricant and grease according to the
atmosphere and lubricant (grease) high quality suggest a suited EPT for three
months.
(5) Constantly verify the inlet air filter, clear or substitute the filter in time.
(6) Blower overload often not quickly shown, so shell out focus to
the ingestion and exhaust pressure, bearing temperature and the existing increase tendencies
of motor to figure out regardless of whether the blower performs normally
(seven) Prior to disassembling the blower, the assembling relation and proportions
should be recorded or measured, make marks on elements to guarantee the unique
requirements following assembling.
(eight) When recently device or overhaul, the oil tank should be cleaned ahead of use
and propose change all grease following 8 hours operating.

Typical failure cause and troubleshooting

No Failure Achievable causes Elimination methods
one Friction
in between the
impeller
(1) Impurities on the impeller,
ensuing in the gap is way too small
(2) Gear put on, resulting in a
large backlash
(three) The equipment is not properly mounted,
can not sustain the impeller
synchronization
(4) Bearing put on ensuing in
clearance increasing.
(one) Take away grime and verify
no matter whether there is injury areas
(2) Alter the gear gap, substitute
the gears if the equipment backlash is
higher than the average thirty% to
fifty%
(3)Re-assemble the gears, keep
the taper speak to location is to 75%
(four)Replace the bearing
two Collision
in between
impeller and
wall, the
impeller top
and casing
(one) Installation gap is not appropriate
(two) operating pressure is way too
higher, exceeding the specified
benefit
(3) Working temperature is too large
(4) Casing or base deformation,
positioning fan failure
(5) Bearing axial place is not very good
(1) Change the gap
(two) Identify leads to of
overloading, decreased the pressure
to the specified value
(three) Examine the installation
precision and lessen the pipe
tension
(four) Examine and repair bearings,
and to make certain the clearance
(five)Relocation
3 Temperature
also large
(one) Oil in tank is as well a lot, as well
thick or way too dirty
(2) Filter or silencer is blocked
(3)The pressure is larger than
the specified benefit
(four)Excessive wear of the
impeller, large hole
(five)Bad ventilation, indoor
temperature is higher, resulting in
inlet air’s higher temperature
(6) The rotating pace is also reduced,outcome in the belt slipping.
(1)Decrease the oil stage or depend on
oil
(two)Eliminate of blocking objects
(three)Decreasing the pressure by means of
the blower
(4)Mend its clearance
(five)Open vents to reduce place
temperature
(six) Boost pace to avert the
belt slipping.
four Inadequate
circulation
(1) The inlet filter is blocked
(2) Impeller put on and the gap
increases too much
(three) Belt slipping
(4) Big imports stress loss
(five) Pipeline ventilation leakage
(1) Cleanse the filter dust and
obstruction
(2) Fix the hole
(3)Tighten the belt and enhance
the number of belts
(4)Alter the inlet stress to the
specified value
(five) Verify and mend the pipeline
5 Oil leaking or
oil leaking
into the enclosure
(one)Higher tank situation trigger
leakage from the discharge port
(two) Seal use, resulting in shaft oil spills
(3) The strain is larger than
the specified value

 
(1)Decrease the oil degree
(two)Replace the seals
(3)Very clear the air vents, 2mm diameter faucet is set in the
center chamber, open up the faucet
below the wall
6 Irregular
vibration and
noise
(1)Bearing clearance exceeds the
specified worth or bearing use
(two) The equipment backlash is also
large, not in a tight fixed
(3) The international objects and dust
brought on by the impeller and the
impeller, the impeller and the
housing collision
(4) the impeller shaft
deformation triggered the collision
triggered by overload,
(five) Friction in between the impeller
and the inlet housing triggered by
overheating
(six) Unbalance of the impeller
brought on by fouling or foreign
human body
(seven) Anchor bolts or other
fasteners are loosened
(1)Substitute bearings or bearing
seat
(2)Reassemble equipment and make sure
backlash
(3)Cleaning blower, examine the
situation is ruined
(four)Check the back pressure, check out
the wheel and change hole
(five)Verify the filter and back
force, improve the hole
between the impeller inlet and the
casing
(six)Clean the impeller and the
casing, to make sure that the impeller
clearance perform
(7) Tighten the anchor bolts and
leveling the foundation.
seven Motor
overload
(1)In contrast with the needed
stress, the stress distinction
is huge that the back force or
the inlet pressure is high
(two) In comparison with the
equipment demands, blower
circulation is way too big, so its pressure
will increase
(3)Inlet filter is blocked, or outlet
pipe is obstructed or blocked
(4) Collusion or friction (stuck)
rotating areas
(five) The oil amount is as well substantial
(six) Slim V-belt is overheat,
vibration is also huge, or pulley
is too little
(one) Reduce the strain to the
specified price
(2) Exhaust the surplus fuel into
the environment or decrease the
blower velocity
(three) Remove the obstructions
(4)Instantly shut down, check out
the explanation
(five) Alter the oil to the proper
level
(six) Check the belt rigidity, and
changed it with huge diameter
pulley.
