The operating basic principle of the 3-blade roots blower: two 3-lobed rotors are arranged in the cavity, and the
suction port and the discharge port are opened on the two sides of the cavity. Through the action of a pair of
synchronous gears, the two rotors rotate in reverse instructions 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.

Characteristic of our roots blower:
1. Huge adjustment of the air volume
2. Lower Sounds
3. Higher efficiency
4. Low strength cosumption
five. Prolonged time lifestyle
six. Trustworthy operating, effortless routine maintenance,little footprint

Our Roots Blower Workshop

         Doosn Horzitonal CZPT Heart

The Application of the Roots Blower

Routine maintenance and inspection
(one) Verify all fasteners and locating pins circumstances whether they are loosening.
(2) Always verify whether or not the leakage phenomenon of the body.
(3) Spend interest to lubrication, volume of grease and noises when working,
determine regardless of whether it operates below the required circumstances.
(4) CZPT & grease: The lubricant is for medium load industrial equipment oil
(quality 220, kinematic viscosity of 198 ~ 242mm2 / s 40ºC, flash point ≥ 200ºC)
The grease is butter (synthetic lithium grease penetration 220-250, drop position ≥
190ºC). Replace the lubricant and grease soon after very first 200 hrs managing, and substitute
once more soon after a moth running. Later, replace the lubricant and grease according to the
setting and lubricant (grease) quality suggest a suitable alternative for three
(5) Constantly check the inlet air filter, clear or exchange the filter in time.
(6) Blower overload at times not immediately displayed, so pay attention to
the consumption and exhaust pressure, bearing temperature and the current improve trends
of motor to figure out no matter whether the blower works typically
(7) Prior to disassembling the blower, the assembling relation and dimensions
have to be recorded or measured, make marks on parts to make certain the CZPT
specifications after assembling.
(eight) When recently machine or overhaul, the oil tank must be cleaned prior to use
and propose substitute all grease right after eight hours working.

Frequent failure cause and troubleshooting

No Failure Feasible factors Elimination approaches
one Friction
amongst the
(1) Impurities on the impeller,
resulting in the gap is way too little
(2) Gear wear, resulting in a
big backlash
(3) The equipment is not nicely fixed,
can not sustain the impeller
(4) Bearing use resulting in
clearance growing.
(one) Eliminate grime and examine
whether or not there is damage components
(two) Adjust the gear hole, exchange
the gears if the equipment backlash is
greater than the common thirty% to
(3)Re-assemble the gears, preserve
the taper speak to region is to 75%
(four)Substitute the bearing
2 Collision
impeller and
wall, the
impeller prime
and casing
(one) Set up hole is not appropriate
(two) operating strain is way too
high, exceeding the specified
(3) Working temperature is way too large
(four) Casing or base deformation,
positioning fan failure
(5) Bearing axial place is not great
(one) Adjust the gap
(two) Determine causes of
overloading, lowered the stress
to the specified worth
(3) Examine the set up
accuracy and minimize the pipe
(four) Verify and restore bearings,
and to make sure the clearance
3 Temperature
as well large
(one) Oil in tank is as well significantly, also
thick or way too dirty
(two) CZPT or silencer is blocked
(three)The force is greater than
the specified benefit
(4)Extreme wear of the
impeller, big hole
(5)Bad ventilation, indoor
temperature is high, ensuing in
inlet air's large temperature
(6) The rotating pace is too low,result in the belt slipping.
(1)Decrease the oil level or rely on
(2)Remove of blocking objects
(three)Decreasing the strain through
the blower
(4)Repair its clearance
(five)Open up vents to reduce space
(6) Improve velocity to stop the
belt slipping.
4 Inadequate
(one) The inlet filter is blocked
(2) Impeller dress in and the hole
will increase as well a lot
(three) Belt slipping
(4) Big imports force reduction
(5) CZPT air flow leakage
(one) Thoroughly clean the filter dust and
(2) Mend the hole
(3)Tighten the belt and boost
the amount of belts
(4)Alter the inlet pressure to the
specified value
(five) Verify and fix the pipeline
5 Oil leaking or
oil leaking
into the enclosure
(1)Large tank situation result in
leakage from the discharge port
(2) Seal wear, resulting in shaft oil spills
(3) The strain is larger than
the specified price

(1)Lessen the oil stage
(two)Substitute the seals
(3)Obvious the air vents, 2mm diameter faucet is mounted in the
center chamber, open the faucet
beneath the wall
6 Abnormal
vibration and
(1)Bearing clearance exceeds the
specified value or bearing put on
(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
(four) the impeller shaft
deformation induced the collision
induced by overload,
(5) Friction among the impeller
and the inlet housing induced by
(6) Unbalance of the impeller
induced by fouling or overseas
(seven) CZPT bolts or other
fasteners are loosened
(1)Replace bearings or bearing
(two)Reassemble gear and make sure
(three)Cleaning blower, examine the
scenario is ruined
(four)Verify the again stress, check out
the wheel and alter gap
(five)Examine the filter and again
strain, increase the hole
among the impeller inlet and the
(six)Thoroughly clean the impeller and the
casing, to make sure that the impeller
clearance work
(seven) Tighten the anchor bolts and
leveling the foundation.
seven Motor
(1)Compared with the required
strain, the force distinction
is large that the back again stress or
the inlet pressure is higher
(2) In contrast with the
tools demands, blower
circulation is way too large, so its force
(3)Inlet filter is blocked, or outlet
pipe is obstructed or blocked
(four) Collusion or friction (stuck)
rotating components
(5) The oil stage is as well substantial
(6) Slim V-belt is overheat,
vibration is also large, or pulley
is way too modest
(1) Reduce the strain to the
specified benefit
(two) Exhaust the excessive gasoline into
the atmosphere or decrease the
blower speed
(3) Eliminate the obstructions
(four)Instantly shut down, examine
the purpose
(five) Alter the oil to the appropriate
(6) Examine the belt pressure, and
changed it with massive diameter
