The functioning theory of the 3-blade roots blower: two 3-lobed rotors are organized in the cavity, and the
suction port and the discharge port are opened on the two sides of the cavity. Through 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
function of blowing.

The Software of the Roots Blower
Maintenance and inspection
(1) Check out all fasteners and locating pins conditions no matter whether they are loosening.
(two) Constantly verify regardless of whether the leakage phenomenon of the body.
(three) Shell out attention to lubrication, quantity of grease and noises when managing,
establish no matter whether it works under the required conditions.
(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, drop point ≥
190ºC). Substitute the lubricant and grease soon after very first two hundred hrs operating, and replace
yet again after a moth managing. Later, substitute the lubricant and grease according to the
setting and lubricant (grease) top quality propose a suitable alternative for a few
months.
(five) Constantly check the inlet air filter, thoroughly clean or replace the filter in time.
(six) Blower overload often not instantly shown, so spend attention to
the consumption and exhaust pressure, bearing temperature and the recent enhance developments
of motor to determine whether or not the blower functions normally
(7) Just before disassembling the blower, the assembling relation and proportions
have to be recorded or calculated, make marks on factors to guarantee the CZPT
requirements following assembling.
(eight) When newly machine or overhaul, the oil tank need to be cleaned prior to use
and suggest replace all grease after 8 several hours working.
Common failure purpose and troubleshooting
No | Failure | Possible causes | Elimination strategies |
one | Friction in between the impeller |
(1) Impurities on the impeller, ensuing in the gap is as well modest (2) Gear dress in, resulting in a large backlash (3) The gear is not effectively mounted, can not sustain the impeller synchronization (four) Bearing wear resulting in clearance growing. |
(one) Take away dirt and check out whether or not there is injury components (2) Change the gear gap, change the gears if the gear backlash is better than the regular thirty% to fifty% (3)Re-assemble the gears, hold the taper contact region is to seventy five% (four)Substitute the bearing |
2 | Collision in between impeller and wall, the impeller top and casing |
(1) Installation hole is not right (2) running pressure is too higher, exceeding the specified worth (3) Functioning temperature is also higher (four) Casing or base deformation, positioning supporter failure (five) Bearing axial location is not good |
(one) Modify the hole (two) Determine leads to of overloading, diminished the stress to the specified price (3) Examine the installation precision and minimize the pipe tension (four) Verify and mend bearings, and to ensure the clearance (5)Relocation |
three | Temperature as well large |
(1) Oil in tank is way too considerably, as well thick or as well dirty (two) CZPT or silencer is blocked (three)The force is larger than the specified worth (four)Abnormal wear of the impeller, massive hole (5)Very poor ventilation, indoor temperature is substantial, ensuing in inlet air’s substantial temperature (six) The rotating pace is way too reduced,outcome in the belt slipping. |
(one)Reduce the oil amount or rely on oil (two)Take away of blocking objects (3)Minimizing the stress through the blower (4)Restore its clearance (5)Open vents to minimize place temperature (6) Increase velocity to avoid the belt slipping. |
4 | Inadequate stream |
(1) The inlet filter is blocked (two) Impeller use and the hole raises way too significantly (three) Belt slipping (four) Huge imports force reduction (five) CZPT air flow leakage |
(1) Thoroughly clean the filter dust and obstruction (two) Fix the gap (three)Tighten the belt and enhance the variety of belts (4)Change the inlet stress to the specified price (five) Examine and repair the pipeline |
5 | Oil leaking or oil leaking into the enclosure |
(1)Large tank situation result in leakage from the discharge port (two) Seal dress in, ensuing in shaft oil spills (3) The force is larger than the specified benefit |
(one)Decrease the oil stage (two)Substitute the seals (3)Obvious the air vents, 2mm diameter faucet is fastened in the center chamber, open up the faucet under the wall |
six | Irregular vibration and noise |
(one)Bearing clearance exceeds the specified benefit or bearing wear (2) The gear backlash is also large, not in a tight mounted (three) The overseas objects and dust brought on by the impeller and the impeller, the impeller and the housing collision (4) the impeller shaft deformation triggered the collision brought on by overload, (five) Friction in between the impeller and the inlet housing caused by overheating (six) Unbalance of the impeller caused by fouling or international physique (7) CZPT bolts or other fasteners are loosened |
(1)Exchange bearings or bearing seat (2)Reassemble gear and guarantee backlash (three)Cleansing blower, verify the scenario is ruined (4)Examine the again force, verify the wheel and change gap (5)Verify the filter and again force, enhance the gap amongst the impeller inlet and the casing (6)Clear the impeller and the casing, to guarantee that the impeller clearance work (7) Tighten the anchor bolts and leveling the foundation. |
seven | Motor overload |
(1)Compared with the required force, the force difference is massive that the back again strain or the inlet strain is higher (two) In contrast with the equipment demands, blower stream is also big, so its force boosts (three)Inlet filter is blocked, or outlet pipe is obstructed or blocked (4) Collusion or friction (caught) rotating elements (5) The oil level is too large (six) Narrow V-belt is overheat, vibration is way too big, or pulley is as well little |
(1) Reduce the pressure to the specified value (2) Exhaust the extra gasoline into the environment or reduce the blower pace (3) Take away the obstructions (four)Quickly shut down, examine the explanation (5) Alter the oil to the right level (6) Check out the belt tension, and replaced it with big diameter pulley. |
