The functioning basic 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 equally sides of the cavity. Through 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 fuel in the chamber is pushed to accomplish the
goal of blowing.

Function of our roots blower:
one. Big adjustment of the air quantity
two. Lower Sounds
three. High effectiveness
four. Minimal energy cosumption
five. Extended time lifestyle
6. Trustworthy working, easy servicing,modest footprint

Our Roots Blower Workshop

         Doosn Horzitonal Equipment Heart

The Software of the Roots Blower

Servicing and inspection
(1) Verify all fasteners and locating pins circumstances whether or not they are loosening.
(2) Always examine whether or not the leakage phenomenon of the body.
(3) Shell out consideration to lubrication, quantity of grease and noises when running,
figure out regardless of whether it performs beneath the essential problems.
(4) Lubricant & 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 (artificial lithium grease penetration 220-250, fall point ≥
190ºC). Substitute the lubricant and grease after very first two hundred hrs operating, and exchange
yet again after a moth operating. Afterwards, replace the lubricant and grease according to the
surroundings and lubricant (grease) high quality propose a suited EPT for three
months.
(five) Usually verify the inlet air filter, clean or substitute the filter in time.
(six) Blower overload often not immediately displayed, so pay attention to
the intake and exhaust strain, bearing temperature and the current increase trends
of motor to figure out regardless of whether the blower operates generally
(7) Just before disassembling the blower, the assembling relation and dimensions
have to be recorded or calculated, make marks on factors to guarantee the first
needs after assembling.
(8) When recently equipment or overhaul, the oil tank need to be cleaned just before use
and suggest replace all grease right after 8 hours managing.

Frequent failure reason and troubleshooting

No Failure Possible reasons Elimination methods
one Friction
among the
impeller
(one) Impurities on the impeller,
resulting in the hole is way too small
(two) Equipment put on, ensuing in a
big backlash
(three) The gear is not properly fixed,
can not sustain the impeller
synchronization
(4) Bearing put on resulting in
clearance rising.
(1) Eliminate grime and verify
whether there is injury areas
(two) Adjust the equipment gap, replace
the gears if the gear backlash is
increased than the common 30% to
fifty%
(3)Re-assemble the gears, hold
the taper make contact with location is to 75%
(4)Substitute the bearing
two Collision
among
impeller and
wall, the
impeller best
and casing
(1) Installation hole is not correct
(two) functioning strain is too
high, exceeding the specified
value
(three) Running temperature is too higher
(4) Casing or foundation deformation,
positioning supporter failure
(five) Bearing axial area is not excellent
(1) Change the hole
(two) Recognize leads to of
overloading, lowered the stress
to the specified value
(3) Examine the installation
precision and lessen the pipe
tension
(four) Check out and fix bearings,
and to make certain the clearance
(5)Relocation
3 Temperature
too large
(1) Oil in tank is too a lot, as well
thick or as well dirty
(2) Filter or silencer is blocked
(three)The stress is increased than
the specified worth
(four)Extreme dress in of the
impeller, massive hole
(five)Poor air flow, indoor
temperature is substantial, ensuing in
inlet air’s high temperature
(six) The rotating velocity is also reduced,end result in the belt slipping.
(one)Minimize the oil level or rely on
oil
(two)Take away of blocking objects
(three)Decreasing the strain via
the blower
(4)Mend its clearance
(five)Open vents to lessen place
temperature
(6) Increase pace to avoid the
belt slipping.
four Insufficient
circulation
(one) The inlet filter is blocked
(two) Impeller use and the hole
increases as well considerably
(three) Belt slipping
(4) Large imports strain decline
(five) Pipeline ventilation leakage
(1) Thoroughly clean the filter dust and
obstruction
(2) Mend the hole
(3)Tighten the belt and boost
the amount of belts
(four)Change the inlet stress to the
specified price
(five) Check out and mend the pipeline
five Oil leaking or
oil leaking
into the enclosure
(one)Large tank place lead to
leakage from the discharge port
(2) Seal wear, resulting in shaft oil spills
(three) The strain is larger than
the specified worth

 
(1)Decrease the oil level
(2)Substitute the seals
(three)Clear the air vents, 2mm diameter faucet is fastened in the
middle chamber, open up the faucet
below the wall
6 Abnormal
vibration and
sounds
(one)Bearing clearance exceeds the
specified price or bearing wear
(two) The gear backlash is as well
large, not in a restricted mounted
(3) The overseas objects and dust
triggered by the impeller and the
impeller, the impeller and the
housing collision
(4) the impeller shaft
deformation triggered the collision
induced by overload,
(5) Friction amongst the impeller

seat
(2)Reassemble gear and ensure
backlash
(three)Cleansing blower, verify the
case is ruined
(4)Verify the again pressure, check out
the wheel and modify hole
(five)Check the filter and back
strain, increase the gap
in between the impeller inlet and the
casing
(six)Clean the impeller and the
casing, to make certain that the impeller
clearance work
(7) Tighten the anchor bolts and
leveling the foundation.
7 Motor
overload
(1)When compared with the needed
force, the stress big difference
is big that the again strain or
the inlet pressure is substantial
(two) Compared with the
equipment requirements, blower
circulation is way too huge, so its pressure
raises
(three)Inlet filter is blocked, or outlet
pipe is obstructed or blocked
(4) Collusion or friction (stuck)
rotating areas
(5) The oil level is as well substantial
(six) Slim V-belt is overheat,
vibration is as well big, or pulley
is too little
(1) Lessen the strain to the
specified value
(two) Exhaust the excess fuel into
the ambiance or minimize the
blower pace
(three) Get rid of the obstructions
(four)Instantly shut down, examine
the cause
