The functioning basic principle of the a few-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. Via the action 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
objective of blowing.

Function of our roots blower:
1. Big adjustment of the air volume
2. Low Noise
3. Higher performance
four. Minimal vitality cosumption
5. Lengthy time daily life
six. Trustworthy operating, effortless servicing,tiny footprint

The Software of the Roots Blower

Maintenance and inspection
(1) Check out all fasteners and finding pins problems whether or not they are loosening.
(two) Usually check regardless of whether the leakage phenomenon of the body.
(three) Pay focus to lubrication, volume of grease and noises when operating,
determine whether it performs under the required conditions.
(four) CZPT & 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 (artificial lithium grease penetration 220-250, fall position ≥
190ºC). Replace the lubricant and grease right after 1st two hundred several hours managing, and exchange
yet again right after a moth operating. Later on, replace the lubricant and grease according to the
surroundings and lubricant (grease) good quality suggest a suitable substitution for three
(five) Often verify the inlet air filter, clean or substitute the filter in time.
(6) Blower overload sometimes not immediately displayed, so shell out attention to
the ingestion and exhaust stress, bearing temperature and the present enhance traits
of motor to decide whether the blower works typically
(7) Just before disassembling the blower, the assembling relation and proportions
need to be recorded or calculated, make marks on factors to make sure the CZPT
needs right after assembling.
(eight) When freshly equipment or overhaul, the oil tank must be cleaned ahead of use
and propose exchange all grease soon after 8 hrs working.

Frequent failure cause and troubleshooting

No Failure Attainable causes Elimination strategies
1 Friction
between the
(one) Impurities on the impeller,
ensuing in the gap is also modest
(2) Gear use, resulting in a
huge backlash
(three) The gear is not properly fixed,
can not sustain the impeller
(4) Bearing dress in ensuing in
clearance increasing.
(1) Eliminate filth and examine
regardless of whether there is hurt components
(two) Alter the equipment gap, change
the gears if the equipment backlash is
greater than the average thirty% to
(3)Re-assemble the gears, maintain
the taper contact spot is to seventy five%
(four)Exchange the bearing
two Collision
impeller and
wall, the
impeller leading
and casing
(1) Set up hole is not appropriate
(two) operating stress is also
higher, exceeding the specified
(3) Operating temperature is way too substantial
(4) Casing or foundation deformation,
positioning enthusiast failure
(5) Bearing axial place is not very good
(one) Adjust the hole
(2) Recognize leads to of
overloading, decreased the stress
to the specified value
(3) Check the set up
precision and lessen the pipe
(4) Verify and mend bearings,
and to make sure the clearance
three Temperature
as well substantial
(one) Oil in tank is too a lot, also
thick or also dirty
(two) CZPT or silencer is blocked
(3)The strain is greater than
the specified value
(four)Excessive put on of the
impeller, huge hole
(5)Bad air flow, indoor
temperature is large, resulting in
inlet air’s high temperature
(six) The rotating speed is also low,outcome in the belt slipping.
(1)Lessen the oil stage or count on
(2)Remove of blocking objects
(three)Minimizing the force through
the blower
(four)Fix its clearance
(5)Open up vents to lessen space
(six) Boost pace to stop the
belt slipping.
4 Insufficient
(1) The inlet filter is blocked
(two) Impeller put on and the gap
increases way too considerably
(three) Belt slipping
(4) Large imports strain decline
(5) CZPT air flow leakage
(one) Thoroughly clean the filter dust and
(2) Fix the gap
(3)Tighten the belt and enhance
the amount of belts
(4)Change the inlet stress to the
specified price
(five) Verify and mend the pipeline
5 Oil leaking or
oil leaking
into the enclosure
(one)High tank placement lead to
leakage from the discharge port
(two) Seal use, ensuing in shaft oil spills
(3) The pressure is increased than
the specified worth

(1)Decrease the oil amount
(2)Change the seals
(three)Obvious the air vents, 2mm diameter faucet is fastened in the
middle chamber, open the faucet
under the wall
six Abnormal
vibration and
(one)Bearing clearance exceeds the
specified value or bearing put on
(two) The equipment backlash is too
big, not in a tight set
(three) The international objects and dust
induced by the impeller and the
impeller, the impeller and the
housing collision
(four) the impeller shaft
deformation triggered the collision
caused by overload,
(five) Friction among the impeller
and the inlet housing caused by
(6) Unbalance of the impeller
triggered by fouling or foreign
(7) CZPT bolts or other
fasteners are loosened
(one)Change bearings or bearing
(2)Reassemble equipment and make sure
(3)Cleansing blower, check out the
circumstance is ruined
(four)Examine the back force, check
the wheel and modify hole
(five)Verify the filter and back
force, enhance the gap
between the impeller inlet and the
(6)Clean the impeller and the
casing, to ensure that the impeller
clearance function
(seven) Tighten the anchor bolts and
leveling the foundation.
7 Motor
(1)In contrast with the required
pressure, the pressure variation
is big that the back stress or
the inlet strain is higher
(two) In comparison with the
equipment requirements, blower
circulation is also massive, so its strain
(three)Inlet filter is blocked, or outlet
pipe is obstructed or blocked
(four) Collusion or friction (caught)
rotating components
(5) The oil amount is way too higher
(6) Slim V-belt is overheat,
vibration is too large, or pulley
is also little
(1) Minimize the stress to the
specified benefit
(2) Exhaust the excess gas into
the ambiance or lessen the
blower velocity
(3) Eliminate the obstructions
(four)Right away shut down, check
the purpose
(five) Alter the oil to the correct
(6) Verify the belt stress, and
changed it with large diameter
