The functioning 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. By way of the action of a pair of
synchronous gears, the two rotors rotate in opposite 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 accomplish the
purpose of blowing.

Function of our roots blower:
1. Massive adjustment of the air volume
two. Reduced Noise
three. High effectiveness
four. Low strength cosumption
five. Lengthy time lifestyle
6. Reputable running, simple servicing,little footprint

The Software of the Roots Blower

Servicing and inspection
(1) Verify all fasteners and locating pins conditions whether or not they are loosening.
(2) Often examine regardless of whether the leakage phenomenon of the human body.
(three) Shell out interest to lubrication, quantity of grease and noises when working,
figure out whether or not it operates underneath the required circumstances.
(four) 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). Exchange the lubricant and grease following very first two hundred hours operating, and exchange
again right after a moth running. Later on, exchange the lubricant and grease in accordance to the
surroundings and lubricant (grease) top quality suggest a ideal alternative for a few
months.
(5) Usually check out the inlet air filter, clear or exchange the filter in time.
(6) Blower overload occasionally not instantly shown, so spend attention to
the consumption and exhaust force, bearing temperature and the current boost developments
of motor to figure out whether the blower operates usually
(seven) Just before disassembling the blower, the assembling relation and proportions
must be recorded or measured, make marks on factors to make certain the CZPT
requirements after assembling.
(8) When newly device or overhaul, the oil tank ought to be cleaned before use
and suggest substitute all grease following 8 several hours running.

Common failure purpose and troubleshooting

No Failure Attainable reasons Elimination techniques
1 Friction
between the
impeller
(one) Impurities on the impeller,
ensuing in the hole is way too modest
(2) Equipment put on, resulting in a
big backlash
(3) The gear is not effectively fastened,
can not keep the impeller
synchronization
(four) Bearing use resulting in
clearance rising.
(1) Remove dust and verify
no matter whether there is hurt parts
(2) Modify the equipment gap, replace
the gears if the gear backlash is
better than the common 30% to
fifty%
(3)Re-assemble the gears, maintain
the taper speak to area is to 75%
(four)Exchange the bearing
2 Collision
amongst
impeller and
wall, the
impeller top
and casing
(1) Installation hole is not appropriate
(two) operating force is way too
higher, exceeding the specified
worth
(3) Functioning temperature is too high
(four) Casing or foundation deformation,
positioning admirer failure
(5) Bearing axial location is not excellent
(one) Alter the gap
(2) Discover triggers of
overloading, reduced the force
to the specified benefit
(three) Verify the set up
precision and lessen the pipe
tension
(4) Check and repair bearings,
and to make certain the clearance
(five)Relocation
three Temperature
way too large
(1) Oil in tank is also considerably, as well
thick or way too filthy
(two) CZPT or silencer is blocked
(three)The strain is increased than
the specified worth
(four)Excessive put on of the
impeller, big hole
(five)Bad air flow, indoor
temperature is high, ensuing in
inlet air’s high temperature
(six) The rotating pace is too low,consequence in the belt slipping.
(one)Decrease the oil amount or depend on
oil
(two)Get rid of of blocking objects
(3)Decreasing the strain via
the blower
(4)Restore its clearance
(5)Open up vents to lessen place
temperature
(six) Improve pace to prevent the
belt slipping.
four Insufficient
movement
(one) The inlet filter is blocked
(two) Impeller put on and the hole
boosts as well considerably
(three) Belt slipping
(four) Large imports strain reduction
(five) CZPT air flow leakage
(1) Clear the filter dust and
obstruction
(2) Fix the hole
(3)Tighten the belt and enhance
the quantity of belts
(four)Adjust the inlet strain to the
specified worth
(5) Examine and fix the pipeline
five Oil leaking or
oil leaking

(3)Distinct the air vents, 2mm diameter faucet is fixed in the
center chamber, open the faucet
below the wall
six Abnormal
vibration and
sound
(one)Bearing clearance exceeds the
specified worth or bearing use
(two) The gear backlash is too
huge, not in a restricted fixed
(three) The international objects and dust
triggered by the impeller and the
impeller, the impeller and the
housing collision
(four) the impeller shaft
deformation caused the collision

seat
(2)Reassemble gear and make sure
backlash
(three)Cleansing blower, examine the
scenario is destroyed
(four)Examine the again force, verify
the wheel and alter hole
(five)Verify the filter and back again
pressure, improve the gap
amongst the impeller inlet and the
casing
(6)Cleanse the impeller and the
casing, to ensure that the impeller
clearance work
(7) Tighten the anchor bolts and
leveling the base.
7 Motor
overload
(1)In contrast with the required
pressure, the stress distinction
is massive that the back again pressure or
the inlet stress is high
(two) When compared with the
equipment needs, blower
movement is also massive, so its force
boosts
(3)Inlet filter is blocked, or outlet
pipe is obstructed or blocked
(four) Collusion or friction (caught)
rotating components
(five) The oil stage is also higher
(six) Slim V-belt is overheat,
vibration is too big, or pulley
is as well small
(one) Lessen the pressure to the
specified price
(two) Exhaust the excess gas into
the ambiance or decrease the
blower pace
(three) Get rid of the obstructions
(four)Instantly shut down, examine
the cause
