The doing work principle of the a few-blade roots blower: two 3-lobed rotors are arranged in the cavity, and the
suction port and the discharge port are opened on both sides of the cavity. Via the action of a pair of
synchronous gears, the two rotors rotate in opposite instructions 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
goal of blowing.
Feature of our roots blower:
1. Large adjustment of the air quantity
2. Reduced Noise
three. Higher performance
4. Reduced energy cosumption
five. Long time life
6. Dependable working, easy routine maintenance,tiny footprint

Servicing and inspection
(one) Check all fasteners and locating pins conditions whether or not they are loosening.
(two) Usually verify whether or not the leakage phenomenon of the body.
(3) Spend focus to lubrication, volume of grease and noises when running,
determine regardless of whether it functions below the needed circumstances.
(four) CZPT & grease: The lubricant is for medium load industrial equipment oil
(grade 220, kinematic viscosity of 198 ~ 242mm2 / s 40ºC, flash level ≥ 200ºC)
The grease is butter (synthetic lithium grease penetration 220-250, drop stage ≥
190ºC). Exchange the lubricant and grease right after first two hundred hrs running, and change
once again after a moth managing. Later, exchange the lubricant and grease in accordance to the
surroundings and lubricant (grease) top quality propose a suited substitute for three
months.
(5) Usually check out the inlet air filter, clean or change the filter in time.
(6) Blower overload often not immediately exhibited, so spend consideration to
the ingestion and exhaust pressure, bearing temperature and the existing boost traits
of motor to establish no matter whether the blower functions typically
(seven) Ahead of disassembling the blower, the assembling relation and dimensions
must be recorded or calculated, make marks on factors to make sure the CZPT
demands right after assembling.
(8) When newly machine or overhaul, the oil tank ought to be cleaned before use
and suggest exchange all grease right after eight hours working.
Common failure explanation and troubleshooting
No | Failure | Feasible reasons | Elimination approaches |
1 | Friction between the impeller |
(one) Impurities on the impeller, ensuing in the gap is also little (two) Equipment dress in, resulting in a big backlash (3) The gear is not effectively set, can not maintain the impeller synchronization (four) Bearing dress in ensuing in clearance escalating. |
(one) Get rid of filth and check whether or not there is harm areas (two) Modify the gear gap, change the gears if the gear backlash is better than the regular 30% to 50% (three)Re-assemble the gears, maintain the taper get in touch with area is to seventy five% (four)Substitute the bearing |
two | Collision among impeller and wall, the impeller top and casing |
(1) Installation hole is not appropriate (two) functioning force is also higher, exceeding the specified price (three) Functioning temperature is as well high (four) Casing or base deformation, positioning admirer failure (five) Bearing axial place is not great |
(one) Alter the hole (two) Determine brings about of overloading, reduced the pressure to the specified price (3) Examine the installation accuracy and decrease the pipe rigidity (four) Verify and mend bearings, and to make sure the clearance (5)Relocation |
3 | Temperature also high |
(1) Oil in tank is too considerably, too thick or too filthy (two) CZPT or silencer is blocked (three)The pressure is larger than the specified worth (four)Too much wear of the impeller, large gap (five)Bad ventilation, indoor temperature is higher, ensuing in inlet air’s substantial temperature (six) The rotating pace is too low,result in the belt slipping. |
(one)Reduce the oil amount or rely on oil (2)Remove of blocking objects (three)Minimizing the force by means of the blower (four)Repair its clearance (five)Open up vents to lessen place temperature (six) Boost speed to prevent the belt slipping. |
four | Insufficient stream |
(1) The inlet filter is blocked (2) Impeller dress in and the gap increases way too significantly (three) Belt slipping (4) Massive imports pressure loss (5) CZPT air flow leakage |
(1) Clear the filter dust and obstruction (2) Mend the hole (3)Tighten the belt and improve the quantity of belts (four)Modify the inlet force to the specified price (five) Examine and repair the pipeline |
5 | Oil leaking or oil leaking into the enclosure |
(one)Substantial tank situation result in leakage from the discharge port (2) Seal dress in, ensuing in shaft oil spills (3) The force is higher than the specified benefit |
(1)Decrease the oil level (two)Change the seals (three)Distinct the air vents, 2mm diameter faucet is fixed in the middle chamber, open the faucet below the wall |
6 | Irregular vibration and noise |
(one)Bearing clearance exceeds the specified benefit or bearing wear (two) The equipment backlash is also huge, not in a limited mounted (3) The foreign objects and dust triggered by the impeller and the impeller, the impeller and the housing collision (4) the impeller shaft deformation brought on the collision induced by overload, (five) Friction among the impeller and the inlet housing caused by overheating (6) Unbalance of the impeller brought on by fouling or international body (seven) CZPT bolts or other fasteners are loosened |
(1)Exchange bearings or bearing seat (2)Reassemble equipment and make sure backlash (3)Cleansing blower, check out the circumstance is destroyed (4)Check the again stress, examine the wheel and change gap (five)Check out the filter and again stress, boost the gap amongst the impeller inlet and the casing (six)Clear the impeller and the casing, to guarantee that the impeller clearance operate (7) Tighten the anchor bolts and leveling the base. |
seven | Motor overload |
(1)When compared with the needed strain, the strain big difference is big that the again strain or the inlet strain is substantial (2) When compared with the products requirements, blower flow is too huge, so its strain will increase (3)Inlet filter is blocked, or outlet pipe is obstructed or blocked (four) Collusion or friction (stuck) rotating elements (five) The oil level is way too large (six) Slim V-belt is overheat, vibration is also big, or pulley is also modest |
(one) Decrease the force to the specified price (2) Exhaust the surplus gas into the ambiance or lessen the blower velocity (three) Eliminate the obstructions (four)Right away shut down, examine the explanation (five) Adjust the oil to the appropriate level (6) Check the belt pressure, and replaced it with massive diameter pulley. |
