The functioning theory of the a few-blade roots blower: two 3-lobed rotors are organized in the cavity, and the
suction port and the discharge port are opened on both 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 achieve the
function of blowing.

Function of our roots blower:
1. Large adjustment of the air quantity
two. Low Sounds
3. High efficiency
4. Lower energy cosumption
5. Long time life
six. Dependable working, straightforward maintenance,tiny footprint

The Software of the Roots Blower

Routine maintenance and inspection
(1) Check all fasteners and locating pins conditions regardless of whether they are loosening.
(2) Usually examine regardless of whether the leakage phenomenon of the human body.
(three) Shell out consideration to lubrication, sum of grease and noises when running,
determine regardless of whether it functions below the required situations.
(4) CZPT & grease: The lubricant is for medium load industrial gear oil
(grade 220, kinematic viscosity of 198 ~ 242mm2 / s 40ºC, flash point ≥ 200ºC)
The grease is butter (artificial lithium grease penetration 220-250, fall position ≥
190ºC). Exchange the lubricant and grease following first 200 hours running, and substitute
once again following a moth operating. Later, exchange the lubricant and grease in accordance to the
setting and lubricant (grease) good quality propose a suitable substitution for 3
months.
(five) Usually examine the inlet air filter, thoroughly clean or change the filter in time.
(6) Blower overload often not instantly shown, so pay out focus to
the ingestion and exhaust strain, bearing temperature and the recent improve traits
of motor to decide whether or not the blower functions typically
(seven) Prior to disassembling the blower, the assembling relation and proportions
have to be recorded or measured, make marks on elements to make certain the CZPT
specifications right after assembling.
(eight) When newly equipment or overhaul, the oil tank need to be cleaned ahead of use
and suggest substitute all grease following eight hours managing.

Widespread failure explanation and troubleshooting

No Failure Attainable motives Elimination techniques
one Friction
amongst the
impeller
(one) Impurities on the impeller,
resulting in the hole is way too modest
(two) Gear use, resulting in a
huge backlash
(3) The gear is not nicely fixed,
can not keep the impeller
synchronization
(4) Bearing put on resulting in
clearance increasing.
(one) Eliminate dirt and examine
regardless of whether there is injury components
(two) Alter the gear gap, replace
the gears if the equipment backlash is
increased than the average 30% to
50%
(3)Re-assemble the gears, keep
the taper speak to spot is to 75%
(four)Change the bearing
2 Collision
among
impeller and
wall, the
impeller prime
and casing
(1) Installation hole is not proper
(2) functioning strain is as well
large, exceeding the specified
benefit
(three) Running temperature is as well substantial
(four) Casing or base deformation,
positioning enthusiast failure
(five) Bearing axial area is not great
(1) Change the hole
(2) Identify leads to of
overloading, reduced the strain
to the specified value
(3) Check the set up
precision and reduce the pipe
pressure
(four) Check out and fix bearings,
and to make sure the clearance
(five)Relocation
three Temperature
also large
(one) Oil in tank is also considerably, too
thick or too dirty
(two) CZPT or silencer is blocked
(3)The stress is increased than
the specified price
(4)Extreme put on of the
impeller, huge hole
(five)Bad air flow, indoor
temperature is substantial, resulting in
inlet air’s substantial temperature
(six) The rotating pace is as well minimal,outcome in the belt slipping.
(one)Lessen the oil level or count on
oil
(two)Remove of blocking objects
(3)Minimizing the stress through
the blower
(four)Restore its clearance
(five)Open up vents to lessen room
temperature
(6) Enhance speed to avoid the
belt slipping.
four Insufficient
circulation
(one) The inlet filter is blocked
(2) Impeller wear and the hole
boosts as well a lot
(three) Belt slipping
(4) Huge imports pressure loss
(5) CZPT air flow leakage
(1) Clear the filter dust and
obstruction
(2) Mend the hole
(3)Tighten the belt and improve
the amount of belts
(four)Alter the inlet force to the
specified worth
(five) Check out and mend the pipeline
five Oil leaking or
oil leaking
into the enclosure
(one)Large tank place lead to
leakage from the discharge port
(2) Seal put on, ensuing in shaft oil spills
(3) The strain is increased than

(2)Change the seals
(3)Clear the air vents, 2mm diameter faucet is mounted in the
center chamber, open up the faucet
under the wall
six Abnormal
vibration and
sound
(1)Bearing clearance exceeds the
specified benefit or bearing use
(2) The gear backlash is also
massive, not in a tight mounted
(three) The foreign objects and dust
triggered by the impeller and the
impeller, the impeller and the
housing collision
(four) the impeller shaft
deformation caused the collision

seat
(two)Reassemble equipment and guarantee
backlash
(three)Cleaning blower, check out the
circumstance is ruined
(four)Check the back again force, check out
the wheel and change gap
(five)Verify the filter and back
pressure, enhance the hole
in between the impeller inlet and the
casing
(six)Cleanse the impeller and the
casing, to guarantee that the impeller
clearance operate
(seven) Tighten the anchor bolts and
leveling the foundation.
7 Motor
overload
(1)Compared with the needed
stress, the stress difference
is large that the back again stress or
the inlet pressure is higher
(two) In comparison with the
equipment demands, blower
circulation is also massive, so its stress
raises
(three)Inlet filter is blocked, or outlet
pipe is obstructed or blocked
(four) Collusion or friction (stuck)
rotating components
(five) The oil amount is too large
(six) Narrow V-belt is overheat,
vibration is also large, or pulley
is too little
(1) Reduce the stress to the
specified benefit
(2) Exhaust the extra fuel into
the ambiance or minimize the
blower pace
(3) Eliminate the obstructions
(4)Quickly shut down, check out
the explanation
