The working theory of the a few-blade roots blower: two a few-lobed rotors are organized in the cavity, and the
suction port and the discharge port are opened on equally sides of the cavity. Via 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 gasoline in the chamber is pushed to accomplish the
goal of blowing.

Attribute of our roots blower:
1. Huge adjustment of the air volume
2. Reduced Sound
three. High effectiveness
4. Low power cosumption
five. Lengthy time life
six. Reputable working, straightforward servicing,little footprint

The Software of the Roots Blower

Maintenance and inspection
(1) Check all fasteners and locating pins situations no matter whether they are loosening.
(2) Usually examine no matter whether the leakage phenomenon of the entire body.
(3) Shell out interest to lubrication, amount of grease and noises when operating,
figure out no matter whether it works below the required problems.
(4) Lubricant & grease: The lubricant is for medium load industrial equipment oil
(grade 220, kinematic viscosity of 198 ~ 242mm2 / s 40ºC, flash point ≥ 200ºC)
The grease is butter (artificial lithium grease penetration 220-250, drop level ≥
190ºC). Replace the lubricant and grease following very first two hundred several hours operating, and exchange
again after a moth running. Later, change the lubricant and grease according to the
atmosphere and lubricant (grease) high quality suggest a ideal EPT for 3
(5) Usually verify the inlet air filter, cleanse or change the filter in time.
(6) Blower overload often not immediately displayed, so shell out consideration to
the consumption and exhaust strain, bearing temperature and the current increase developments
of motor to determine no matter whether the blower operates usually
(seven) Before disassembling the blower, the assembling relation and dimensions
need to be recorded or calculated, make marks on parts to guarantee the authentic
specifications right after assembling.
(8) When freshly device or overhaul, the oil tank need to be cleaned just before use
and propose substitute all grease soon after 8 several hours running.

Widespread failure cause and troubleshooting

No Failure Achievable factors Elimination approaches
one Friction
amongst the
(1) Impurities on the impeller,
resulting in the hole is too little
(2) Gear put on, ensuing in a
huge backlash
(3) The gear is not effectively fixed,
can not preserve the impeller
(4) Bearing wear resulting in
clearance escalating.
(one) Take away dirt and check out
regardless of whether there is damage areas
(2) Modify the gear gap, exchange
the gears if the gear backlash is
greater than the average 30% to
(three)Re-assemble the gears, hold
the taper make contact with region is to seventy five%
(four)Exchange the bearing
2 Collision
impeller and
wall, the
impeller top
and casing
(1) Set up hole is not appropriate
(2) working strain is as well
substantial, exceeding the specified
(3) Running temperature is also high
(four) Casing or base deformation,
positioning enthusiast failure
(five) Bearing axial location is not very good
(one) Adjust the gap
(2) Identify leads to of
overloading, diminished the stress
to the specified benefit
(3) Verify the installation
accuracy and reduce the pipe
(four) Examine and repair bearings,
and to guarantee the clearance
three Temperature
as well large
(one) Oil in tank is as well a lot, too
thick or too dirty
(2) Filter or silencer is blocked
(3)The pressure is increased than
the specified benefit
(four)Excessive use of the
impeller, huge gap
(five)Bad ventilation, indoor
temperature is higher, resulting in
inlet air’s large temperature
(6) The rotating pace is too reduced,consequence in the belt slipping.
(one)Decrease the oil amount or depend on
(2)Get rid of of blocking objects
(three)Lowering the pressure by way of
the blower
(four)Repair its clearance
(five)Open up vents to decrease place
(6) Increase velocity to prevent the
belt slipping.
four Insufficient
(1) The inlet filter is blocked
(two) Impeller put on and the gap
increases as well much
(three) Belt slipping
(four) Massive imports stress loss
(5) Pipeline ventilation leakage
(one) Clear the filter dust and
(two) Repair the hole
(three)Tighten the belt and improve
the amount of belts
(four)Adjust the inlet pressure to the
specified price
(5) Verify and restore the pipeline
5 Oil leaking or
oil leaking
into the enclosure
(1)Large tank situation cause
leakage from the discharge port
(two) Seal dress in, resulting in shaft oil spills
(three) The pressure is increased than
the specified worth

(1)Lessen the oil degree
(two)Replace the seals
(3)Clear the air vents, 2mm diameter faucet is fixed in the
center chamber, open the faucet
under the wall
six Abnormal
vibration and
(1)Bearing clearance exceeds the
specified value or bearing put on
(2) The gear backlash is also
massive, not in a limited set
(3) The international objects and dust
triggered by the impeller and the
impeller, the impeller and the
housing collision
(4) the impeller shaft
deformation caused the collision
brought on by overload,
(5) Friction among the impeller
and the inlet housing triggered by
(six) Unbalance of the impeller
caused by fouling or foreign
(7) Anchor bolts or other
fasteners are loosened

(two)Reassemble equipment and make certain
(3)Cleaning blower, examine the
circumstance is damaged
(four)Check out the back again stress, check
the wheel and alter gap
(5)Check out the filter and back
force, boost the gap
between the impeller inlet and the
(six)Cleanse the impeller and the
casing, to make certain that the impeller
clearance function
(7) Tighten the anchor bolts and
leveling the base.
7 Motor
(one)In comparison with the essential
strain, the strain distinction
is massive that the back stress or
the inlet force is high
(2) Compared with the
equipment requirements, blower
stream is way too huge, so its force
(3)Inlet filter is blocked, or outlet
pipe is obstructed or blocked
(4) Collusion or friction (trapped)
rotating components
(five) The oil degree is too higher
(6) Slender V-belt is overheat,
vibration is too large, or pulley
is way too tiny
(1) Minimize the strain to the
specified price
(two) Exhaust the excessive fuel into
the atmosphere or minimize the
blower pace
(three) Get rid of the obstructions
(4)Right away shut down, examine
the reason
(five) Change the oil to the correct
(6) Check the belt rigidity, and
replaced it with large diameter
