The functioning basic principle of the 3-blade roots blower: two a few-lobed rotors are organized in the cavity, and the
suction port and the discharge port are opened on both sides of the cavity. Via the action 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 gasoline in the chamber is pushed to attain the
objective of blowing.

Attribute of our roots blower:

The Software of the Roots Blower

Servicing and inspection
(one) Examine all fasteners and locating pins conditions whether they are loosening.
(two) Constantly check no matter whether the leakage phenomenon of the entire body.
(3) Spend consideration to lubrication, quantity of grease and noises when operating,
figure out no matter whether it functions underneath the essential problems.
(4) CZPT & grease: The lubricant is for medium load industrial equipment oil
(quality 220, kinematic viscosity of 198 ~ 242mm2 / s 40ºC, flash level ≥ 200ºC)
The grease is butter (synthetic lithium grease penetration 220-250, drop position ≥
190ºC). Change the lubricant and grease following initial 200 several hours operating, and change
yet again soon after a moth running. Later on, replace the lubricant and grease according to the
atmosphere and lubricant (grease) top quality suggest a suitable replacement for 3
months.
(5) Usually verify the inlet air filter, cleanse or substitute the filter in time.
(6) Blower overload sometimes not right away displayed, so pay consideration to
the consumption and exhaust pressure, bearing temperature and the present improve developments
of motor to figure out whether the blower performs typically
(seven) Ahead of disassembling the blower, the assembling relation and dimensions
need to be recorded or measured, make marks on components to ensure the CZPT
specifications soon after assembling.
(eight) When newly machine or overhaul, the oil tank ought to be cleaned prior to use
and propose replace all grease soon after eight hours managing.

Typical failure reason and troubleshooting

No Failure Possible factors Elimination strategies
one Friction
between the
impeller
(1) Impurities on the impeller,
ensuing in the gap is way too tiny
(2) Equipment use, ensuing in a
massive backlash
(three) The gear is not properly set,
can not sustain the impeller
synchronization
(four) Bearing wear ensuing in
clearance growing.
(one) Remove filth and check
whether there is damage elements
(2) Modify the equipment gap, replace
the gears if the gear backlash is
higher than the regular thirty% to
50%
(three)Re-assemble the gears, hold
the taper make contact with location is to seventy five%
(4)Substitute the bearing
two Collision
amongst
impeller and
wall, the
impeller leading
and casing
(1) Installation gap is not right
(2) operating stress is too
substantial, exceeding the specified
worth
(three) Functioning temperature is also higher
(four) Casing or foundation deformation,
positioning admirer failure
(5) Bearing axial area is not excellent
(one) Alter the hole
(two) Determine leads to of
overloading, reduced the pressure
to the specified benefit
(3) Examine the set up
precision and minimize the pipe
tension
(4) Check and fix bearings,
and to make sure the clearance
(5)Relocation
three Temperature
too higher
(1) Oil in tank is also considerably, way too
thick or also soiled
(2) CZPT or silencer is blocked
(3)The stress is higher than
the specified value
(four)Excessive wear of the
impeller, huge hole
(5)Poor air flow, indoor
temperature is higher, ensuing in
inlet air’s large temperature
(six) The rotating velocity is also minimal,result in the belt slipping.
(one)Lessen the oil stage or depend on
oil
(two)Get rid of of blocking objects
(3)Lowering the pressure by means of
the blower
(four)Restore its clearance
(five)Open vents to reduce place
temperature
(6) Increase speed to stop the
belt slipping.
4 Inadequate
movement
(one) The inlet filter is blocked
(two) Impeller wear and the hole
boosts as well significantly
(3) Belt slipping
(four) Big imports strain decline
(5) CZPT air flow leakage
(one) Cleanse the filter dust and
obstruction
(two) Restore the hole
(3)Tighten the belt and increase
the amount of belts
(4)Adjust the inlet force to the
specified price
(5) Verify and restore the pipeline
five Oil leaking or
oil leaking
into the enclosure
(one)Substantial tank placement lead to
leakage from the discharge port
(2) Seal wear, ensuing in shaft oil spills
(three) The pressure is increased than
the specified benefit

 
(1)Reduce the oil stage
(2)Substitute the seals
(three)Clear the air vents, 2mm diameter faucet is set in the
middle chamber, open up the faucet
below the wall
six Abnormal
vibration and
sound
(1)Bearing clearance exceeds the
specified benefit or bearing wear
(2) The gear backlash is too
huge, not in a tight fastened
(three) The foreign objects and dust
brought on by the impeller and the
impeller, the impeller and the
housing collision
(four) the impeller shaft
deformation brought on the collision
caused by overload,

seat
(2)Reassemble equipment and make sure
backlash
(3)Cleaning blower, check the
case is damaged
(4)Verify the back again pressure, check out
the wheel and alter gap
(five)Verify the filter and back again
strain, increase the hole
amongst the impeller inlet and the
casing
(6)Thoroughly clean the impeller and the
casing, to make sure that the impeller
clearance work
(seven) Tighten the anchor bolts and
leveling the base.
7 Motor
overload
(one)In contrast with the required
pressure, the strain variation
is large that the back again strain or
the inlet force is high
(2) In contrast with the
products requirements, blower
stream is way too large, so its strain
will increase
(3)Inlet filter is blocked, or outlet
pipe is obstructed or blocked
(4) Collusion or friction (stuck)
rotating areas
(five) The oil level is too higher
(six) Slender V-belt is overheat,
vibration is way too massive, or pulley
is way too modest
(one) Lessen the pressure to the
specified worth
(2) Exhaust the excessive gas into
the ambiance or decrease the
blower speed
(three) Remove the obstructions
(four)Quickly shut down, check
the cause
(5) Change the oil to the correct
stage
(6) Verify the belt pressure, and
replaced it with big diameter
pulley.
