The doing work principle of the 3-blade roots blower: two 3-lobed rotors are organized in the cavity, and the
suction port and the discharge port are opened on equally sides of the cavity. By way of 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 fuel in the chamber is pushed to attain the
goal of blowing.

Attribute of our roots blower:
1. Massive adjustment of the air quantity
2. Lower Sounds
three. Higher efficiency
four. Minimal vitality cosumption
five. Long time daily life
six. Reputable operating, straightforward upkeep,little footprint

The Software of the Roots Blower

Upkeep and inspection
(one) Verify all fasteners and locating pins situations regardless of whether they are loosening.
(two) Always check out regardless of whether the leakage phenomenon of the body.
(three) Shell out focus to lubrication, sum of grease and noises when operating,
figure out whether or not it functions below the required circumstances.
(four) Lubricant & grease: The lubricant is for medium load industrial gear oil
(grade 220, kinematic viscosity of 198 ~ 242mm2 / s 40ºC, flash stage ≥ 200ºC)
The grease is butter (synthetic lithium grease penetration 220-250, drop position ≥
190ºC). Replace the lubricant and grease after very first 200 several hours running, and change
once again after a moth working. Later, replace the lubricant and grease in accordance to the
setting and lubricant (grease) quality suggest a suited EPT for 3
months.
(five) Always check the inlet air filter, clear or replace the filter in time.
(6) Blower overload at times not right away displayed, so shell out attention to
the intake and exhaust force, bearing temperature and the existing improve developments
of motor to establish no matter whether the blower works usually
(7) Prior to disassembling the blower, the assembling relation and dimensions
should be recorded or calculated, make marks on components to guarantee the authentic
needs following assembling.
(eight) When recently machine or overhaul, the oil tank should be cleaned before use
and suggest replace all grease right after 8 hrs managing.

Common failure cause and troubleshooting

No Failure Feasible causes Elimination methods
one Friction
in between the
impeller
(1) Impurities on the impeller,
ensuing in the gap is too small
(2) Gear dress in, ensuing in a
massive backlash
(three) The gear is not effectively mounted,
can not keep the impeller
synchronization
(4) Bearing wear resulting in
clearance rising.
(1) Take away dust and check
regardless of whether there is damage parts
(2) Adjust the gear hole, change
the gears if the gear backlash is
better than the common 30% to
fifty%
(three)Re-assemble the gears, keep
the taper make contact with spot is to 75%
(four)Change the bearing
2 Collision
amongst
impeller and
wall, the
impeller leading
and casing
(one) Set up gap is not appropriate
(two) operating force is way too
higher, exceeding the specified
value
(3) Working temperature is too large
(four) Casing or base deformation,
positioning admirer failure
(5) Bearing axial spot is not great
(one) Alter the hole
(2) Discover triggers of
overloading, diminished the stress
to the specified benefit
(3) Check out the installation
precision and decrease the pipe
tension
(four) Verify and restore bearings,
and to ensure the clearance
(five)Relocation
3 Temperature
way too higher
(1) Oil in tank is way too much, as well
thick or as well soiled
(2) Filter or silencer is blocked
(3)The force is greater than
the specified price
(four)Excessive use of the
impeller, huge gap
(5)Inadequate ventilation, indoor
temperature is higher, resulting in
inlet air’s high temperature
(six) The rotating speed is way too lower,end result in the belt slipping.
(one)Reduce the oil degree or depend on
oil
(2)Take away of blocking objects
(3)Reducing the pressure by means of
the blower
(4)Restore its clearance
(five)Open vents to lessen space
temperature
(six) Enhance velocity to prevent the
belt slipping.
four Insufficient
flow
(1) The inlet filter is blocked
(two) Impeller use and the gap
raises way too a lot
(3) Belt slipping
(4) Massive imports force decline
(5) Pipeline ventilation leakage
(1) Thoroughly clean the filter dust and
obstruction
(two) Repair the hole
(3)Tighten the belt and improve
the variety of belts
(4)Modify the inlet pressure to the
specified value
(5) Check out and repair the pipeline
5 Oil leaking or
oil leaking
into the enclosure
(one)High tank situation trigger
leakage from the discharge port
(two) Seal put on, resulting in shaft oil spills
(three) The force is increased than
the specified price

 
(one)Lessen the oil degree
(two)Change the seals
(three)Very clear the air vents, 2mm diameter faucet is fixed in the
center chamber, open the faucet
under the wall
6 Abnormal
vibration and
noise
(1)Bearing clearance exceeds the
specified worth or bearing wear
(2) The equipment backlash is as well
massive, not in a tight fastened
(3) The international 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
brought on by overload,
(5) Friction amongst the impeller
and the inlet housing induced by
overheating
(6) Unbalance of the impeller
induced by fouling or foreign
physique
(seven) Anchor bolts or other
fasteners are loosened
(1)Replace bearings or bearing
seat
(two)Reassemble gear and guarantee
backlash
(3)Cleansing blower, check out the
case is destroyed
(four)Check out the back again stress, check out
the wheel and adjust gap
(5)Examine the filter and again
force, improve the gap
amongst the impeller inlet and the
casing
(6)Clean the impeller and the
casing, to guarantee that the impeller
clearance operate
(7) Tighten the anchor bolts and
leveling the foundation.
7 Motor
overload
(one)When compared with the needed
stress, the stress distinction
is huge that the back strain or
the inlet strain is high
(two) In comparison with the
products requirements, blower
stream is also big, so its strain
boosts
(three)Inlet filter is blocked, or outlet
pipe is obstructed or blocked
(four) Collusion or friction (caught)
rotating components
(5) The oil stage is way too substantial
(six) Narrow V-belt is overheat,
vibration is way too massive, or pulley
is also small
(one) Minimize the force to the
specified worth
(two) Exhaust the excess gas into
the environment or lessen the
blower speed
(3) Take away the obstructions
(4)Instantly shut down, verify
the explanation
(5) Adjust the oil to the correct
level
(six) Verify the belt tension, and
changed it with large diameter
pulley.
