The doing work basic principle of the 3-blade roots blower: two a few-lobed rotors are arranged in the cavity, and the
suction port and the discharge port are opened on both sides of the cavity. By way of the motion 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 fuel in the chamber is pushed to attain the
purpose of blowing.
Feature of our roots blower:
one. Huge adjustment of the air volume
2. Reduced Sound
three. Higher efficiency
four. Lower strength cosumption
five. Long time lifestyle
6. Trustworthy operating, straightforward servicing,little footprint

The Application of the Roots Blower
Maintenance and inspection
(one) Verify all fasteners and finding pins circumstances regardless of whether they are loosening.
(two) Constantly verify regardless of whether the leakage phenomenon of the human body.
(3) Pay out interest to lubrication, amount of grease and noises when managing,
figure out whether or not it functions under the required conditions.
(four) 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 (artificial lithium grease penetration 220-250, fall position ≥
190ºC). Change the lubricant and grease after 1st two hundred several hours working, and substitute
yet again following a moth operating. Later, exchange the lubricant and grease in accordance to the
surroundings and lubricant (grease) high quality propose a suitable alternative for 3
months.
(5) Often verify the inlet air filter, clean or change the filter in time.
(6) Blower overload sometimes not right away displayed, so shell out interest to
the intake and exhaust stress, bearing temperature and the recent enhance trends
of motor to establish no matter whether the blower operates usually
(seven) Ahead of disassembling the blower, the assembling relation and proportions
should be recorded or measured, make marks on factors to guarantee the CZPT
specifications right after assembling.
(eight) When newly equipment or overhaul, the oil tank must be cleaned just before use
and propose substitute all grease following eight hours running.
Common failure cause and troubleshooting
No | Failure | Achievable causes | Elimination techniques |
one | Friction among the impeller |
(1) Impurities on the impeller, ensuing in the hole is too small (2) Equipment dress in, ensuing in a huge backlash (3) The equipment is not well mounted, can not maintain the impeller synchronization (4) Bearing use resulting in clearance growing. |
(1) Get rid of grime and examine whether or not there is hurt areas (2) Change the gear gap, replace the gears if the equipment backlash is better than the typical thirty% to 50% (3)Re-assemble the gears, maintain the taper make contact with region is to 75% (four)Change the bearing |
two | Collision in between impeller and wall, the impeller best and casing |
(1) Installation gap is not proper (two) running stress is way too high, exceeding the specified benefit (3) Running temperature is as well high (4) Casing or base deformation, positioning fan failure (five) Bearing axial area is not good |
(1) Adjust the gap (2) Discover causes of overloading, diminished the force to the specified value (3) Check the installation precision and lessen the pipe pressure (four) Check out and repair bearings, and to guarantee the clearance (five)Relocation |
three | Temperature also substantial |
(one) Oil in tank is as well a lot, also thick or too dirty (2) CZPT or silencer is blocked (three)The pressure is larger than the specified benefit (four)Extreme dress in of the impeller, massive gap (5)Very poor ventilation, indoor temperature is high, ensuing in inlet air’s large temperature (6) The rotating velocity is too lower,end result in the belt slipping. |
(1)Reduce the oil stage or rely on oil (2)Remove of blocking objects (three)Lowering the pressure by way of the blower (4)Repair its clearance (5)Open vents to reduce place temperature (6) Increase velocity to stop the belt slipping. |
4 | Insufficient stream |
(one) The inlet filter is blocked (two) Impeller put on and the hole increases as well significantly (3) Belt slipping (four) Large imports pressure loss (five) CZPT air flow leakage |
(1) Thoroughly clean the filter dust and obstruction (two) Repair the hole (three)Tighten the belt and increase the amount of belts (four)Adjust the inlet force to the specified value (5) Check out and mend the pipeline |
5 | Oil leaking or oil leaking into the enclosure |
(one)High tank position trigger leakage from the discharge port (2) Seal use, resulting in shaft oil spills (three) The force is larger than the specified value |
(one)Decrease the oil amount (two)Exchange the seals (three)Obvious the air vents, 2mm diameter faucet is fastened in the middle chamber, open the faucet under the wall |
six | Irregular vibration and sound |
(one)Bearing clearance exceeds the specified price or bearing wear (two) The gear backlash is as well large, not in a tight mounted (three) The foreign 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 between the impeller and the inlet housing induced by overheating (6) Unbalance of the impeller induced by fouling or overseas body (7) CZPT bolts or other fasteners are loosened |
(one)Substitute bearings or bearing seat (2)Reassemble gear and make certain backlash (three)Cleansing blower, verify the circumstance is damaged (four)Verify the back force, verify the wheel and change hole (5)Check the filter and back again force, improve the hole amongst the impeller inlet and the casing (6)Clear the impeller and the casing, to make sure that the impeller clearance perform (7) Tighten the anchor bolts and leveling the base. |
seven | Motor overload |
(one)In contrast with the required pressure, the force big difference is huge that the again stress or the inlet strain is higher (2) Compared with the tools demands, blower stream is way too large, so its force boosts (three)Inlet filter is blocked, or outlet pipe is obstructed or blocked (4) Collusion or friction (stuck) rotating components (five) The oil degree is as well substantial (six) Slender V-belt is overheat, vibration is also large, or pulley is as well little |
(1) Decrease the pressure to the specified benefit (2) Exhaust the surplus gas into the ambiance or reduce the blower speed (three) Remove the obstructions (four)Instantly shut down, check out the purpose (five) Alter the oil to the appropriate degree (6) Check the belt stress, and replaced it with large diameter pulley. |
