The doing work basic principle of the a few-blade roots blower: two a few-lobed rotors are arranged in the cavity, and the
suction port and the discharge port are opened on both sides of the cavity. Via the motion 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 gas in the chamber is pushed to attain the
purpose of blowing.

Feature of our roots blower:
1. Huge adjustment of the air volume
2. Reduced Noise
three. Large performance
4. Minimal power cosumption
five. Long time daily life
6. Dependable managing, simple upkeep,little footprint

The Application of the Roots Blower

Servicing and inspection
(one) Check out all fasteners and locating pins situations no matter whether they are loosening.
(two) Often examine no matter whether the leakage phenomenon of the body.
(three) Pay focus to lubrication, sum of grease and noises when managing,
figure out whether or not it performs beneath the required problems.
(4) CZPT & grease: The lubricant is for medium load industrial gear oil
(quality 220, kinematic viscosity of 198 ~ 242mm2 / s 40ºC, flash position ≥ 200ºC)
The grease is butter (artificial lithium grease penetration 220-250, fall stage ≥
190ºC). Change the lubricant and grease right after first two hundred hrs managing, and replace
again following a moth working. Later on, substitute the lubricant and grease in accordance to the
atmosphere and lubricant (grease) good quality propose a appropriate substitution for three
months.
(five) Often examine the inlet air filter, cleanse or substitute the filter in time.
(6) Blower overload occasionally not immediately exhibited, so spend attention to
the ingestion and exhaust pressure, bearing temperature and the present boost tendencies
of motor to decide whether the blower functions normally
(seven) Prior to disassembling the blower, the assembling relation and proportions
should be recorded or calculated, make marks on factors to ensure the CZPT
requirements right after assembling.
(8) When freshly equipment or overhaul, the oil tank must be cleaned ahead of use
and suggest replace all grease following eight hours managing.

Widespread failure cause and troubleshooting

No Failure Possible factors Elimination techniques
1 Friction
between the
impeller
(one) Impurities on the impeller,
resulting in the gap is as well little
(two) Gear dress in, ensuing in a
big backlash
(three) The equipment is not well set,
can not maintain the impeller
synchronization
(4) Bearing dress in ensuing in
clearance increasing.
(one) Get rid of filth and examine
no matter whether there is hurt components
(two) Modify the equipment gap, substitute
the gears if the gear backlash is
higher than the average 30% to
fifty%
(three)Re-assemble the gears, hold
the taper make contact with region is to seventy five%
(four)Replace the bearing
2 Collision
among
impeller and
wall, the
impeller top
and casing
(one) Set up hole is not correct
(2) functioning pressure is too
large, exceeding the specified
price
(three) Functioning temperature is also high
(4) Casing or base deformation,
positioning admirer failure
(five) Bearing axial place is not great
(1) Adjust the gap
(two) Recognize brings about of
overloading, lowered the force
to the specified benefit
(3) Verify the installation
accuracy and reduce the pipe
stress
(four) Examine and fix bearings,
and to ensure the clearance
(5)Relocation
three Temperature
way too higher
(1) Oil in tank is as well a lot, too
thick or too dirty
(2) CZPT or silencer is blocked
(three)The strain is increased than
the specified value
(4)Extreme put on of the
impeller, huge hole
(5)Bad ventilation, indoor
temperature is substantial, resulting in
inlet air’s high temperature
(six) The rotating pace is as well lower,end result in the belt slipping.
(1)Decrease the oil level or count on
oil
(two)Get rid of of blocking objects
(3)Reducing the force through
the blower
(four)Fix its clearance
(five)Open vents to decrease space
temperature

6 Irregular
vibration and
sounds
(one)Bearing clearance exceeds the
specified worth or bearing put on
(two) The equipment backlash is also
large, not in a limited fastened
(three) The foreign objects and dust
induced by the impeller and the
impeller, the impeller and the
housing collision

the wheel and alter gap
(5)Check out the filter and back again
stress, enhance the hole
in between the impeller inlet and the
casing
(6)Clean the impeller and the
casing, to make sure that the impeller
clearance perform
(seven) Tighten the anchor bolts and
leveling the foundation.
seven Motor
overload
(one)In comparison with the required
pressure, the force difference
is massive that the again pressure or
the inlet pressure is substantial
(2) In comparison with the
tools demands, blower
movement is also big, so its strain
boosts
(3)Inlet filter is blocked, or outlet
pipe is obstructed or blocked
(four) Collusion or friction (stuck)
rotating areas
(five) The oil stage is also substantial
(six) Narrow V-belt is overheat,
vibration is as well massive, or pulley
is as well tiny
(1) Lessen the strain to the
specified value
(two) Exhaust the excess gas into
the atmosphere or lessen the
blower velocity
(three) Get rid of the obstructions
(four)Quickly shut down, check out
the reason
