The operating basic principle of the three-blade roots blower: two three-lobed rotors are arranged in the cavity, and the
suction port and the discharge port are opened on both sides of the cavity. By means of 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 achieve the
purpose of blowing.

Function of our roots blower:
1. Huge adjustment of the air volume
2. Minimal Noise
three. Large performance
4. Reduced power cosumption
5. Extended time existence
6. Reliable running, simple routine maintenance,little footprint

         Doosn Horzitonal Device Heart

The Application of the Roots Blower

Servicing and inspection
(one) Check all fasteners and finding pins problems no matter whether they are loosening.
(2) Usually check regardless of whether the leakage phenomenon of the entire body.
(3) Spend attention to lubrication, quantity of grease and noises when running,
decide whether or not it works under 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 (synthetic lithium grease penetration 220-250, drop level ≥
190ºC). Substitute the lubricant and grease right after very first 200 hrs operating, and change
again following a moth working. Later on, replace the lubricant and grease according to the
environment and lubricant (grease) high quality suggest a suited EPT for a few
months.
(five) Often verify the inlet air filter, clear or exchange the filter in time.
(6) Blower overload at times not quickly exhibited, so shell out interest to
the consumption and exhaust stress, bearing temperature and the present boost trends
of motor to decide no matter whether the blower functions usually
(seven) Before disassembling the blower, the assembling relation and dimensions
have to be recorded or measured, make marks on parts to make sure the unique
needs right after assembling.
(8) When recently machine or overhaul, the oil tank must be cleaned ahead of use
and suggest substitute all grease right after eight hours working.

Common failure explanation and troubleshooting

No Failure Possible causes Elimination strategies
1 Friction
among the
impeller
(one) Impurities on the impeller,
ensuing in the hole is as well little
(2) Gear put on, resulting in a
huge backlash
(three) The equipment is not properly fixed,
can not preserve the impeller
synchronization
(four) Bearing use resulting in
clearance rising.
(one) Remove dirt and examine
whether or not there is injury areas
(2) Adjust the gear gap, substitute
the gears if the equipment backlash is
increased than the average 30% to
50%
(three)Re-assemble the gears, preserve
the taper speak to location is to seventy five%
(four)Change the bearing
2 Collision
among
impeller and
wall, the
impeller top
and casing
(one) Set up gap is not proper
(2) functioning strain is way too
large, exceeding the specified
value
(three) Running temperature is way too large
(four) Casing or base deformation,
positioning enthusiast failure
(five) Bearing axial location is not very good
(1) Modify the gap
(2) Discover leads to of
overloading, lowered the strain
to the specified benefit
(three) Check out the set up
precision and minimize the pipe
pressure
(4) Check and mend bearings,
and to guarantee the clearance
(5)Relocation
3 Temperature
as well substantial
(one) Oil in tank is also considerably, way too
thick or too soiled
(2) Filter or silencer is blocked
(3)The stress is larger than
the specified value
(four)Excessive dress in of the
impeller, huge hole
(five)Inadequate air flow, indoor
temperature is substantial, resulting in
inlet air’s substantial temperature
(6) The rotating pace is as well reduced,end result in the belt slipping.
(one)Minimize the oil degree or rely on
oil
(two)Take away of blocking objects
(3)Minimizing the stress via
the blower
(four)Restore its clearance
(five)Open up vents to minimize place
temperature
(six) Enhance pace to stop the
belt slipping.
four Inadequate
stream
(1) The inlet filter is blocked
(two) Impeller use and the hole
boosts as well considerably
(three) Belt slipping
(four) Huge imports force loss
(5) Pipeline air flow leakage
(1) Clear the filter dust and
obstruction
(2) Repair the gap
(three)Tighten the belt and increase
the amount of belts
(four)Modify the inlet force to the
specified price
(five) Check out and fix the pipeline
5 Oil leaking or
oil leaking
into the enclosure
(1)High tank situation trigger
leakage from the discharge port
(2) Seal put on, resulting in shaft oil spills
(3) The strain is increased than
the specified worth

 
(one)Minimize the oil stage
(two)Change the seals
(three)Very clear the air vents, 2mm diameter faucet is fixed in the
center chamber, open the faucet
below the wall
six Irregular
vibration and
sound
(one)Bearing clearance exceeds the
specified price or bearing dress in
(two) The equipment backlash is too
huge, not in a limited set
(three) The overseas objects and dust
brought on by the impeller and the
impeller, the impeller and the
housing collision
(four) the impeller shaft
deformation caused the collision
caused by overload,
(five) Friction among the impeller
and the inlet housing triggered by
overheating
(six) Unbalance of the impeller
brought on by fouling or foreign
physique
(seven) Anchor bolts or other
fasteners are loosened
(1)Replace bearings or bearing
seat
(2)Reassemble gear and guarantee
backlash
(three)Cleaning blower, examine the
case is broken
(4)Check the back force, verify
the wheel and modify hole
(five)Check out the filter and back again
pressure, enhance the gap
amongst the impeller inlet and the
casing
(6)Clean the impeller and the
casing, to guarantee that the impeller
clearance perform
(7) Tighten the anchor bolts and
leveling the base.
seven Motor
overload
(one)When compared with the required
stress, the stress big difference
is large that the back force or
the inlet strain is substantial
(two) In contrast with the
tools requirements, blower
circulation is way too huge, so its strain
raises
(3)Inlet filter is blocked, or outlet
pipe is obstructed or blocked
(4) Collusion or friction (caught)
rotating areas
(five) The oil degree is also high
(six) Narrow V-belt is overheat,
vibration is way too large, or pulley
is also little
(one) Decrease the strain to the
specified benefit
(two) Exhaust the excess gas into
the atmosphere or minimize the
blower pace
(three) Take away the obstructions
(4)Right away shut down, check out
the cause
(5) Adjust the oil to the right
stage
(6) Check the belt stress, and
replaced it with big diameter
pulley.
