The operating basic principle 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 each 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 gas in the chamber is pushed to attain the
objective of blowing.

Characteristic of our roots blower:
one. Massive adjustment of the air volume
2. Low Sound
3. High efficiency
4. Lower vitality cosumption
five. Prolonged time life
six. Reliable running, straightforward upkeep,modest footprint

The Application of the Roots Blower

Servicing and inspection
(1) Examine all fasteners and locating pins conditions whether or not they are loosening.
(2) Usually examine no matter whether the leakage phenomenon of the entire body.
(3) Pay out consideration to lubrication, amount of grease and noises when working,
decide no matter whether it works beneath the necessary circumstances.
(4) CZPT & grease: The lubricant is for medium load industrial equipment oil
(quality 220, kinematic viscosity of 198 ~ 242mm2 / s 40ºC, flash position ≥ 200ºC)
The grease is butter (synthetic lithium grease penetration 220-250, drop stage ≥
190ºC). Substitute the lubricant and grease right after very first 200 hours running, and change
yet again soon after a moth running. Afterwards, change the lubricant and grease according to the
setting and lubricant (grease) quality suggest a suitable substitute for 3
months.
(five) Usually examine the inlet air filter, cleanse or exchange the filter in time.
(six) Blower overload sometimes not instantly shown, so shell out focus to
the consumption and exhaust force, bearing temperature and the current enhance traits
of motor to decide no matter whether the blower performs generally
(seven) Just before disassembling the blower, the assembling relation and dimensions
need to be recorded or calculated, make marks on parts to make certain the CZPT
specifications following assembling.
(eight) When recently device or overhaul, the oil tank should be cleaned just before use
and suggest change all grease after 8 hrs running.

Frequent failure purpose and troubleshooting

No Failure Achievable causes Elimination approaches
1 Friction
in between the
impeller
(1) Impurities on the impeller,
ensuing in the hole is too modest
(2) Equipment wear, ensuing in a
massive backlash
(3) The equipment is not well set,
can not maintain the impeller
synchronization
(4) Bearing dress in ensuing in
clearance rising.
(1) Remove dirt and check out
whether or not there is harm elements
(two) Change the gear hole, exchange
the gears if the equipment backlash is
increased than the regular 30% to
fifty%
(three)Re-assemble the gears, hold
the taper make contact with spot is to seventy five%
(four)Exchange the bearing
2 Collision
between
impeller and
wall, the
impeller best
and casing
(one) Installation gap is not right
(two) functioning pressure is way too
high, exceeding the specified
value
(3) Functioning temperature is way too large
(four) Casing or base deformation,
positioning enthusiast failure
(five) Bearing axial area is not very good
(1) Modify the gap
(two) Discover leads to of
overloading, decreased the stress
to the specified price
(3) Check the installation
precision and minimize the pipe
tension
(4) Check and fix bearings,
and to make sure the clearance
(5)Relocation
3 Temperature
also higher
(1) Oil in tank is also considerably, way too
thick or too dirty
(2) CZPT or silencer is blocked
(three)The stress is greater than
the specified benefit
(four)Excessive use of the
impeller, huge hole
(5)Inadequate air flow, indoor
temperature is large, ensuing in
inlet air’s higher temperature
(six) The rotating pace is as well minimal,outcome in the belt slipping.
(1)Reduce the oil amount or rely on
oil
(2)Remove of blocking objects
(3)Minimizing the pressure via
the blower
(four)Fix its clearance
(five)Open vents to minimize area
temperature
(six) Increase speed to stop the
belt slipping.
four Insufficient
movement
(1) The inlet filter is blocked
(2) Impeller put on and the gap
will increase as well significantly
(three) Belt slipping
(4) Big imports stress decline
(5) CZPT ventilation leakage
(1) Cleanse the filter dust and
obstruction
(two) Fix the gap
(3)Tighten the belt and improve
the number of belts
(four)Change the inlet force to the
specified worth
(five) Check out and restore the pipeline
five Oil leaking or
oil leaking
into the enclosure
(one)Large tank place result in
leakage from the discharge port
(2) Seal put on, ensuing in shaft oil spills
(three) The stress is greater than
the specified worth

 
(one)Decrease the oil level
(2)Replace the seals
(3)Clear the air vents, 2mm diameter faucet is set in the
middle chamber, open the faucet
below the wall
6 Abnormal
vibration and
noise
(1)Bearing clearance exceeds the
specified benefit or bearing dress in
(2) The gear backlash is as well
large, not in a limited fixed
(3) The foreign objects and dust
triggered by the impeller and the
impeller, the impeller and the
housing collision
(4) the impeller shaft
deformation triggered the collision
caused by overload,
(five) Friction among the impeller
and the inlet housing triggered by
overheating
(6) Unbalance of the impeller
caused by fouling or foreign
physique
(7) CZPT bolts or other
fasteners are loosened
(one)Change bearings or bearing
seat
(two)Reassemble equipment and make certain
backlash
(3)Cleansing blower, check the
circumstance is damaged
(four)Examine the back strain, check out
the wheel and change gap
(5)Check out the filter and again
force, boost the gap
in between the impeller inlet and the
casing
(6)Thoroughly clean the impeller and the
casing, to make certain that the impeller
clearance operate
(seven) Tighten the anchor bolts and
leveling the base.
7 Motor
overload
(one)In comparison with the essential
pressure, the force distinction
is big that the again stress or
the inlet stress is higher
(2) Compared with the
equipment demands, blower
circulation is also large, so its strain
raises
(3)Inlet filter is blocked, or outlet
pipe is obstructed or blocked
(4) Collusion or friction (caught)
rotating components
(5) The oil stage is also higher
(6) Narrow V-belt is overheat,
vibration is way too huge, or pulley
is also small
(1) Lessen the pressure to the
specified price
(two) Exhaust the excess gas into
the atmosphere or decrease the
blower velocity
(three) Eliminate the obstructions
(4)Instantly shut down, check
the cause
(5) Modify the oil to the proper
stage
(6) Check the belt rigidity, and
replaced it with huge diameter
pulley.
