The operating basic principle of the 3-blade roots blower: two three-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 motion of a pair of
synchronous gears, the two rotors rotate in opposite directions 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
goal of blowing.

Characteristic of our roots blower:
one. Huge adjustment of the air volume
two. Low Noise
three. Higher effectiveness
four. Reduced vitality cosumption
5. Lengthy time existence
six. Dependable working, easy routine maintenance,little footprint

The Application of the Roots Blower

Routine maintenance and inspection
(1) Check out all fasteners and locating pins problems whether or not they are loosening.
(two) Always verify regardless of whether the leakage phenomenon of the body.
(3) Spend interest to lubrication, volume of grease and noises when working,
establish regardless of whether it performs below the needed conditions.
(four) Lubricant & grease: The lubricant is for medium load industrial equipment oil
(quality 220, kinematic viscosity of 198 ~ 242mm2 / s 40ºC, flash point ≥ 200ºC)
The grease is butter (artificial lithium grease penetration 220-250, fall position ≥
190ºC). Substitute the lubricant and grease after initial 200 hrs managing, and replace
yet again soon after a moth operating. Later on, change the lubricant and grease according to the
atmosphere and lubricant (grease) high quality suggest a appropriate EPT for 3
months.
(5) Usually examine the inlet air filter, cleanse or substitute the filter in time.
(6) Blower overload occasionally not right away exhibited, so pay out interest to
the consumption and exhaust stress, bearing temperature and the current enhance tendencies
of motor to decide whether the blower works normally
(7) Prior to disassembling the blower, the assembling relation and proportions
need to be recorded or measured, make marks on factors to guarantee the first
demands right after assembling.
(8) When freshly machine or overhaul, the oil tank should be cleaned ahead of use
and suggest change all grease after eight hrs managing.

Typical failure cause and troubleshooting

No Failure Possible motives Elimination techniques
1 Friction
in between the
impeller
(1) Impurities on the impeller,
resulting in the gap is as well small
(2) Equipment use, ensuing in a
large backlash
(three) The gear is not properly fastened,
can not maintain the impeller
synchronization
(four) Bearing dress in ensuing in
clearance escalating.
(1) Remove filth and check out
whether or not there is hurt elements
(two) Change the gear hole, change
the gears if the equipment backlash is
greater than the common 30% to
50%
(3)Re-assemble the gears, preserve
the taper get in touch with area is to 75%
(four)Change the bearing
two Collision
between
impeller and
wall, the
impeller top
and casing
(one) Installation hole is not proper
(two) working strain is as well
large, exceeding the specified
benefit
(three) Running temperature is also large
(4) Casing or foundation deformation,
positioning fan failure
(five) Bearing axial area is not great
(1) Alter the hole
(2) Identify triggers of
overloading, decreased the pressure
to the specified price
(3) Verify the set up
precision and decrease the pipe
tension
(four) Verify and mend bearings,
and to guarantee the clearance
(5)Relocation
three Temperature
too large
(1) Oil in tank is way too a lot, too
thick or way too filthy
(2) Filter or silencer is blocked
(three)The force is higher than
the specified price
(4)Extreme dress in of the
impeller, large hole
(5)Inadequate air flow, indoor
temperature is substantial, ensuing in
inlet air’s higher temperature
(6) The rotating speed is also low,result in the belt slipping.
(one)Reduce the oil amount or rely on
oil
(two)Take away of blocking objects
(3)Lowering the strain via
the blower
(4)Repair its clearance
(5)Open vents to minimize place
temperature
(6) Increase velocity to prevent the
belt slipping.
four Insufficient
flow
(one) The inlet filter is blocked
(two) Impeller wear and the hole
will increase too much
(3) Belt slipping
(four) Big imports pressure decline
(five) Pipeline ventilation leakage
(one) Clear the filter dust and
obstruction
(two) Fix the gap
(3)Tighten the belt and enhance
the amount of belts
(4)Alter the inlet force to the
specified value
(5) Check and repair the pipeline
five Oil leaking or
oil leaking
into the enclosure

(3) The force is larger than
the specified value

 
(1)Decrease the oil level
(two)Replace the seals
(three)Distinct the air vents, 2mm diameter faucet is set in the
middle chamber, open the faucet
underneath the wall
six Abnormal
vibration and
noise
(1)Bearing clearance exceeds the
specified price or bearing put on
(2) The equipment backlash is way too
big, not in a tight fixed
(three) The overseas objects and dust
triggered by the impeller and the
impeller, the impeller and the
housing collision
(four) the impeller shaft
deformation triggered the collision
triggered by overload,
(5) Friction amongst the impeller
and the inlet housing triggered by
overheating
(six) Unbalance of the impeller
caused by fouling or overseas
physique

backlash
(3)Cleansing blower, verify the
scenario is destroyed
(four)Check the back again stress, verify
the wheel and adjust gap
(five)Check out the filter and back again
pressure, enhance the hole
between the impeller inlet and the
casing
(six)Clear the impeller and the
casing, to make certain that the impeller
clearance work
(seven) Tighten the anchor bolts and
leveling the base.
seven Motor
overload
(one)In comparison with the essential
stress, the force big difference
is massive that the back strain or
the inlet pressure is higher
(2) In contrast with the
products demands, blower
stream is too large, so its force
will increase
(three)Inlet filter is blocked, or outlet
pipe is obstructed or blocked
(4) Collusion or friction (trapped)
rotating areas
(5) The oil degree is way too large
(6) Narrow V-belt is overheat,
vibration is as well massive, or pulley
is way too little
(1) Minimize the force to the
specified benefit
(two) Exhaust the excess fuel into
the atmosphere or decrease the
blower speed
(three) Get rid of the obstructions
(4)Quickly shut down, examine
the purpose
(five) Modify the oil to the right
degree
(6) Verify the belt tension, and
replaced it with big diameter
pulley.
