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 both sides of the cavity. By means of 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 obtain the
purpose of blowing.

Characteristic of our roots blower:
1. Massive adjustment of the air quantity
2. Lower Sounds
three. Large effectiveness
4. Minimal power cosumption
5. Long time life

The Software of the Roots Blower

Servicing and inspection
(one) Check all fasteners and locating pins conditions no matter whether they are loosening.
(two) Usually check out whether or not the leakage phenomenon of the human body.
(three) Pay consideration to lubrication, quantity of grease and noises when working,
figure out whether it performs below the needed conditions.
(four) CZPT & grease: The lubricant is for medium load industrial gear oil
(quality 220, kinematic viscosity of 198 ~ 242mm2 / s 40ºC, flash level ≥ 200ºC)
The grease is butter (synthetic lithium grease penetration 220-250, fall stage ≥
190ºC). Exchange the lubricant and grease following very first 200 hrs operating, and replace
again following a moth operating. Later, replace the lubricant and grease in accordance to the
setting and lubricant (grease) good quality suggest a ideal replacement for 3
(five) Always examine the inlet air filter, cleanse or change the filter in time.
(6) Blower overload often not instantly exhibited, so pay out focus to
the ingestion and exhaust pressure, bearing temperature and the existing boost traits
of motor to figure out whether or not the blower functions generally
(7) Just before disassembling the blower, the assembling relation and dimensions
should be recorded or calculated, make marks on parts to make certain the CZPT
requirements after assembling.
(8) When newly device or overhaul, the oil tank ought to be cleaned before use
and propose change all grease soon after eight hrs operating.

Typical failure explanation and troubleshooting

No Failure Achievable causes Elimination methods
1 Friction
in between the
(one) Impurities on the impeller,
ensuing in the gap is way too tiny
(2) Equipment put on, ensuing in a
large backlash
(three) The equipment is not properly set,
can not maintain the impeller
(four) Bearing dress in ensuing in
clearance increasing.
(1) Get rid of dirt and verify
whether or not there is hurt parts
(2) Alter the equipment gap, substitute
the gears if the gear backlash is
increased than the typical 30% to
(3)Re-assemble the gears, hold
the taper contact spot is to 75%
(four)Substitute the bearing
two Collision
impeller and
wall, the
impeller top
and casing
(one) Installation hole is not right
(two) working pressure is as well
higher, exceeding the specified
(three) Functioning temperature is as well higher
(four) Casing or base deformation,
positioning enthusiast failure
(five) Bearing axial location is not excellent
(one) Modify the gap
(two) Determine triggers of
overloading, lowered the pressure
to the specified price
(3) Examine the installation
accuracy and reduce the pipe
(4) Verify and restore bearings,
and to make sure the clearance
3 Temperature
also high
(1) Oil in tank is way too a lot, also
thick or too dirty
(two) CZPT or silencer is blocked
(three)The force is larger than
the specified worth
(four)Excessive put on of the
impeller, huge hole
(5)Very poor ventilation, indoor
temperature is higher, ensuing in
inlet air’s large temperature
(6) The rotating velocity is as well reduced,outcome in the belt slipping.
(1)Minimize the oil degree or count on
(2)Get rid of of blocking objects
(3)Lowering the strain via
the blower
(4)Mend its clearance
(5)Open vents to lessen space
(six) Increase velocity to stop the
belt slipping.
four Insufficient
(one) The inlet filter is blocked
(two) Impeller dress in and the gap
increases too much
(3) Belt slipping
(four) Massive imports pressure reduction
(5) CZPT ventilation leakage
(1) Clear the filter dust and
(2) Repair the hole
(three)Tighten the belt and increase
the number of belts
(four)Alter the inlet force to the
specified benefit
(five) Check out and repair the pipeline
five Oil leaking or
oil leaking
into the enclosure
(one)Substantial tank place result in
leakage from the discharge port
(two) Seal wear, resulting in shaft oil spills
(3) The force is greater than
the specified worth

(one)Decrease the oil amount
(2)Exchange the seals
(three)Clear the air vents, 2mm diameter faucet is mounted in the
center chamber, open up the faucet
beneath the wall
six Irregular
vibration and
(1)Bearing clearance exceeds the
specified worth or bearing use
(two) The gear backlash is also
big, not in a restricted set
(three) The international objects and dust
caused by the impeller and the
impeller, the impeller and the
housing collision
(four) the impeller shaft
deformation triggered the collision
induced by overload,
(5) Friction between the impeller
and the inlet housing brought on by
(6) Unbalance of the impeller
caused by fouling or international
human body
(seven) CZPT bolts or other
fasteners are loosened
(one)Replace bearings or bearing
(2)Reassemble equipment and make sure
(three)Cleaning blower, check the
situation is destroyed
(four)Examine the again pressure, examine
the wheel and adjust gap
(5)Check out the filter and back
pressure, enhance the gap
among the impeller inlet and the
(six)Cleanse the impeller and the
casing, to ensure that the impeller
clearance perform
(seven) Tighten the anchor bolts and
leveling the base.
seven Motor
(one)When compared with the necessary
pressure, the strain distinction
is large that the back again pressure or
the inlet force is substantial
(2) Compared with the
products requirements, blower
movement is too big, so its strain
(3)Inlet filter is blocked, or outlet
pipe is obstructed or blocked
(4) Collusion or friction (caught)
rotating components
(5) The oil level is as well large
(6) Slim V-belt is overheat,
vibration is as well huge, or pulley
is as well tiny
(one) Reduce the pressure to the
specified worth
(2) Exhaust the excess fuel into
the atmosphere or reduce the
blower pace
(three) Get rid of the obstructions
(4)Quickly shut down, verify
the reason
(five) Alter the oil to the appropriate
(6) Check the belt tension, and
replaced it with large diameter
