The operating theory of the a few-blade roots blower: two 3-lobed rotors are arranged in the cavity, and the
suction port and the discharge port are opened on the two sides of the cavity. By means of 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 fuel in the chamber is pushed to accomplish the
function of blowing.

Feature of our roots blower:
one. Massive adjustment of the air quantity
2. Reduced Noise
3. High efficiency
4. Reduced power cosumption
five. Lengthy time existence
six. Reliable working, straightforward maintenance,little footprint

The Software of the Roots Blower

Servicing and inspection
(one) Verify all fasteners and locating pins problems no matter whether they are loosening.
(2) Always examine no matter whether the leakage phenomenon of the body.
(3) Spend interest to lubrication, volume of grease and noises when operating,
establish regardless of whether it operates under the required problems.
(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, drop point ≥
190ºC). Replace the lubricant and grease following initial two hundred hrs managing, and substitute
once again soon after a moth operating. Later on, substitute the lubricant and grease in accordance to the
environment and lubricant (grease) high quality propose a suited alternative for three
months.
(five) Constantly check the inlet air filter, thoroughly clean or change the filter in time.
(6) Blower overload often not instantly displayed, so pay focus to
the consumption and exhaust strain, bearing temperature and the recent boost traits
of motor to determine no matter whether the blower performs usually
(seven) Ahead of disassembling the blower, the assembling relation and dimensions
must be recorded or measured, make marks on components to make sure the CZPT
needs soon after assembling.
(eight) When newly equipment or overhaul, the oil tank must be cleaned ahead of use
and suggest substitute all grease after eight hrs operating.

Frequent failure reason and troubleshooting

No Failure Feasible motives Elimination techniques
1 Friction
in between the
impeller
(one) Impurities on the impeller,
resulting in the hole is way too little
(two) Equipment put on, resulting in a
big backlash
(three) The equipment is not effectively fastened,
can not sustain the impeller
synchronization
(4) Bearing wear ensuing in
clearance rising.
(1) Get rid of dirt and check out
whether there is harm elements
(2) Alter the gear gap, exchange
the gears if the gear backlash is
higher than the typical 30% to
fifty%
(three)Re-assemble the gears, keep
the taper make contact with location is to seventy five%
(4)Substitute the bearing
2 Collision
amongst
impeller and
wall, the
impeller prime
and casing
(1) Installation hole is not right
(2) working strain is too
higher, exceeding the specified
price
(3) Operating temperature is too large
(4) Casing or base deformation,
positioning fan failure
(5) Bearing axial location is not very good
(one) Alter the hole
(2) Discover brings about of
overloading, lowered the stress
to the specified price
(three) Check out the installation
accuracy and minimize the pipe
tension
(four) Examine and restore bearings,
and to make sure the clearance
(five)Relocation
three Temperature
too large
(one) Oil in tank is way too considerably, too
thick or also soiled
(2) CZPT or silencer is blocked
(three)The force is greater than
the specified value
(four)Excessive wear of the
impeller, massive hole
(5)Very poor ventilation, indoor
temperature is higher, resulting in
inlet air’s large temperature
(6) The rotating velocity is as well minimal,outcome in the belt slipping.
(one)Decrease the oil level or depend on
oil
(2)Remove of blocking objects
(three)Decreasing the stress by means of
the blower
(four)Repair its clearance
(five)Open vents to reduce space
temperature
(six) Increase pace to prevent the
belt slipping.
four Insufficient
stream
(one) The inlet filter is blocked
(two) Impeller use and the hole
increases too much
(3) Belt slipping
(4) Big imports stress loss
(5) CZPT air flow leakage
(one) Clear the filter dust and
obstruction
(two) Repair the gap
(3)Tighten the belt and boost
the quantity of belts
(4)Modify the inlet stress to the
specified value
(5) Verify and fix the pipeline
5 Oil leaking or
oil leaking
into the enclosure
(1)Higher tank placement trigger
leakage from the discharge port
(two) Seal use, resulting in shaft oil spills
(3) The pressure is larger than
the specified benefit

 
(1)Lessen the oil level

(three)Very clear the air vents, 2mm diameter faucet is mounted in the
middle chamber, open up the faucet
under the wall
6 Irregular
vibration and
sound
(1)Bearing clearance exceeds the
specified benefit or bearing dress in
(2) The gear backlash is too
huge, not in a limited set
(three) The foreign objects and dust
induced by the impeller and the
impeller, the impeller and the
housing collision
(4) the impeller shaft
deformation caused the collision
caused by overload,

seat
(two)Reassemble equipment and make certain
backlash
(three)Cleaning blower, check out the
circumstance is broken
(four)Verify the again stress, check
the wheel and change hole
(five)Examine the filter and again
stress, boost the gap
between the impeller inlet and the
casing
(6)Clear the impeller and the
casing, to make sure that the impeller
clearance work
(seven) Tighten the anchor bolts and
leveling the base.
seven Motor
overload
(one)In contrast with the required
stress, the pressure big difference
is huge that the back again strain or
the inlet stress is substantial
(2) Compared with the
equipment demands, blower
movement is too massive, so its strain
raises
(three)Inlet filter is blocked, or outlet
pipe is obstructed or blocked
(4) Collusion or friction (caught)
rotating areas
(five) The oil stage is way too high
(six) Slim V-belt is overheat,
vibration is too huge, or pulley
is also modest
(1) Minimize the force to the
specified value
(2) Exhaust the extra fuel into
the ambiance or minimize the
blower pace
(3) Remove the obstructions
(four)Instantly shut down, check out
the cause
(5) Change the oil to the proper
amount
(6) Verify the belt pressure, and
changed it with big diameter
pulley.
