The functioning theory 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 the two sides of the cavity. By way of 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 fuel in the chamber is pushed to accomplish the
goal of blowing.

Characteristic of our roots blower:
1. Massive adjustment of the air quantity
two. Minimal Noise
three. High efficiency
4. Low vitality cosumption
five. Prolonged time lifestyle
6. Dependable running, effortless maintenance,tiny footprint

The Application of the Roots Blower

Routine maintenance and inspection
(1) Check all fasteners and locating pins problems whether or not they are loosening.
(2) Usually check no matter whether the leakage phenomenon of the physique.
(three) Spend interest to lubrication, volume of grease and noises when running,
establish whether it performs below the essential problems.
(four) CZPT & grease: The lubricant is for medium load industrial gear oil
(quality 220, kinematic viscosity of 198 ~ 242mm2 / s 40ºC, flash level ≥ 200ºC)
The grease is butter (artificial lithium grease penetration 220-250, drop level ≥
190ºC). Replace the lubricant and grease following 1st 200 hrs operating, and change
once again soon after a moth managing. Afterwards, change the lubricant and grease according to the
environment and lubricant (grease) high quality suggest a suitable substitute for a few
months.
(five) Usually examine the inlet air filter, thoroughly clean or exchange the filter in time.
(six) Blower overload occasionally not quickly exhibited, so spend attention to
the consumption and exhaust force, bearing temperature and the present improve developments
of motor to establish whether the blower functions usually
(7) Ahead of disassembling the blower, the assembling relation and proportions
should be recorded or measured, make marks on components to make sure the CZPT
specifications soon after assembling.
(eight) When freshly equipment or overhaul, the oil tank should be cleaned ahead of use
and suggest exchange all grease following 8 several hours operating.

Widespread failure explanation and troubleshooting

No Failure Possible reasons Elimination approaches
1 Friction
amongst the
impeller
(1) Impurities on the impeller,
resulting in the hole is way too little
(2) Gear use, resulting in a
big backlash
(three) The equipment is not effectively fastened,
can not sustain the impeller
synchronization
(4) Bearing use ensuing in
clearance growing.
(1) Take away grime and check out
whether there is harm parts
(2) Change the gear hole, change
the gears if the equipment backlash is
increased than the common 30% to
50%
(3)Re-assemble the gears, hold
the taper make contact with area is to 75%
(four)Substitute the bearing
two Collision
between
impeller and
wall, the
impeller leading
and casing
(one) Set up gap is not correct
(two) functioning pressure is way too
higher, exceeding the specified
price
(3) Working temperature is as well substantial
(four) Casing or foundation deformation,
positioning supporter failure
(five) Bearing axial place is not excellent
(one) Change the gap
(two) Determine brings about of
overloading, diminished the stress
to the specified worth
(three) Check out the set up
precision and decrease the pipe
rigidity
(4) Examine and repair bearings,
and to make certain the clearance
(5)Relocation
three Temperature
way too higher
(one) Oil in tank is too significantly, as well
thick or as well soiled
(two) CZPT or silencer is blocked
(three)The stress is larger than
the specified benefit
(four)Extreme wear of the
impeller, large gap
(5)Very poor air flow, indoor
temperature is substantial, resulting in
inlet air’s substantial temperature
(6) The rotating velocity is also lower,consequence in the belt slipping.
(one)Lessen the oil level or rely on
oil
(2)Eliminate of blocking objects
(three)Lowering the pressure via
the blower
(4)Repair its clearance
(5)Open up vents to minimize area
temperature
(six) Improve speed to stop the
belt slipping.
4 Insufficient
circulation
(1) The inlet filter is blocked
(two) Impeller wear and the gap
boosts too much
(3) Belt slipping
(4) Big imports stress loss
(five) CZPT air flow leakage
(1) Cleanse the filter dust and
obstruction
(2) Repair the gap
(3)Tighten the belt and enhance
the amount of belts
(four)Adjust the inlet stress to the
specified benefit
(5) Check and restore the pipeline
five Oil leaking or
oil leaking
into the enclosure
(1)Substantial tank position lead to
leakage from the discharge port
(2) Seal dress in, resulting in shaft oil spills
(3) The stress is increased than
the specified price

 
(one)Lessen the oil level
(2)Exchange the seals
(three)Distinct the air vents, 2mm diameter faucet is fixed in the
center chamber, open up the faucet
underneath the wall
six Abnormal
vibration and
sounds
(1)Bearing clearance exceeds the
specified worth or bearing dress in
(two) The gear backlash is way too
huge, not in a limited fastened
(three) The overseas objects and dust
induced by the impeller and the
impeller, the impeller and the
housing collision
(4) the impeller shaft

fasteners are loosened
(1)Replace bearings or bearing
seat
(2)Reassemble equipment and ensure
backlash
(3)Cleaning blower, verify the
circumstance is damaged
(4)Examine the again pressure, examine
the wheel and change gap
(five)Examine the filter and back again
stress, increase the gap
among the impeller inlet and the
casing
(6)Clear the impeller and the
casing, to ensure that the impeller
clearance work
(7) Tighten the anchor bolts and
leveling the base.
7 Motor
overload
(1)Compared with the required
strain, the strain big difference
is big that the back stress or
the inlet pressure is large
(2) When compared with the
equipment specifications, blower
stream is too large, so its stress
raises
(three)Inlet filter is blocked, or outlet
pipe is obstructed or blocked
(four) Collusion or friction (caught)
rotating parts
(5) The oil level is also substantial
(6) Slim V-belt is overheat,
vibration is too big, or pulley
is way too small
(one) Decrease the pressure to the
specified value
(two) Exhaust the surplus fuel into
the ambiance or minimize the
blower velocity
(3) Remove the obstructions
(4)Instantly shut down, check
the explanation
(5) Adjust the oil to the right
stage
(6) Check the belt pressure, and
changed it with big diameter
pulley.
