The working theory of the three-blade roots blower: two a few-lobed rotors are arranged in the cavity, and the
suction port and the discharge port are opened on each sides of the cavity. Through 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 accomplish the
purpose of blowing.
Characteristic of our roots blower:
1. Large adjustment of the air volume
2. Low Noise
3. Large efficiency
four. Reduced energy cosumption
5. Long time life
6. Reputable operating, straightforward routine maintenance,little footprint

The Application of the Roots Blower
Maintenance and inspection
(1) Verify all fasteners and finding pins conditions whether they are loosening.
(2) Often examine regardless of whether the leakage phenomenon of the body.
(3) Pay out attention to lubrication, volume of grease and noises when running,
decide whether it works beneath the required situations.
(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 level ≥
190ºC). Substitute the lubricant and grease soon after first 200 hrs working, and substitute
again soon after a moth operating. Later, exchange the lubricant and grease according to the
setting and lubricant (grease) top quality propose a suited substitution for three
months.
(5) Usually verify the inlet air filter, thoroughly clean or replace the filter in time.
(6) Blower overload at times not quickly displayed, so shell out attention to
the ingestion and exhaust stress, bearing temperature and the current increase trends
of motor to establish regardless of whether the blower performs normally
(seven) Prior to disassembling the blower, the assembling relation and dimensions
should be recorded or calculated, make marks on parts to make sure the CZPT
demands following assembling.
(eight) When freshly machine or overhaul, the oil tank should be cleaned ahead of use
and propose substitute all grease following 8 hours working.
Common failure purpose and troubleshooting
No | Failure | Attainable reasons | Elimination strategies |
1 | Friction among the impeller |
(1) Impurities on the impeller, ensuing in the hole is way too little (2) Equipment put on, ensuing in a big backlash (3) The gear is not effectively mounted, can not keep the impeller synchronization (4) Bearing wear ensuing in clearance increasing. |
(1) Eliminate dust and verify whether or not there is harm areas (two) Change the gear gap, substitute the gears if the gear backlash is greater than the common thirty% to 50% (3)Re-assemble the gears, hold the taper speak to spot is to seventy five% (4)Exchange the bearing |
two | Collision among impeller and wall, the impeller leading and casing |
(1) Set up gap is not right (two) working pressure is as well large, exceeding the specified benefit (3) Functioning temperature is way too high (four) Casing or foundation deformation, positioning supporter failure (5) Bearing axial location is not great |
(one) Change the gap (2) Determine brings about of overloading, diminished the strain to the specified benefit (3) Examine the installation precision and lessen the pipe stress (four) Verify and mend bearings, and to make sure the clearance (5)Relocation |
3 | Temperature too high |
(1) Oil in tank is also a lot, as well thick or also filthy (two) CZPT or silencer is blocked (three)The force is larger than the specified worth (4)Excessive put on of the impeller, massive hole (5)Very poor ventilation, indoor temperature is higher, resulting in inlet air’s large temperature (six) The rotating pace is too lower,result in the belt slipping. |
(one)Reduce the oil level or rely on oil (2)Eliminate of blocking objects (3)Decreasing the pressure by way of the blower (4)Restore its clearance (five)Open up vents to minimize area temperature (6) Boost velocity to avert the belt slipping. |
4 | Insufficient movement |
(1) The inlet filter is blocked (two) Impeller wear and the gap raises way too significantly (3) Belt slipping (four) Big imports force decline (five) CZPT air flow leakage |
(one) Cleanse the filter dust and obstruction (2) Fix the gap (three)Tighten the belt and enhance the amount of belts (four)Modify the inlet strain to the specified price (five) Examine and fix the pipeline |
five | Oil leaking or oil leaking into the enclosure |
(one)Large tank situation result in leakage from the discharge port (two) Seal use, resulting in shaft oil spills (three) The force is larger than the specified price |
(one)Reduce the oil level (two)Change the seals (3)Clear the air vents, 2mm diameter faucet is fixed in the center chamber, open up the faucet underneath the wall |
six | Abnormal vibration and sound |
(one)Bearing clearance exceeds the specified value or bearing put on (2) The equipment backlash is way too massive, not in a limited fastened (3) The overseas objects and dust brought on 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 overheating (six) Unbalance of the impeller caused by fouling or foreign body (7) CZPT bolts or other fasteners are loosened |
(1)Substitute bearings or bearing seat (2)Reassemble equipment and make sure backlash (3)Cleansing blower, verify the case is broken (four)Check the again force, check out the wheel and adjust hole (5)Examine the filter and back force, increase the gap in between the impeller inlet and the casing (6)Clear the impeller and the casing, to make sure that the impeller clearance operate (7) Tighten the anchor bolts and leveling the foundation. |
7 | Motor overload |
(1)Compared with the necessary stress, the strain distinction is huge that the back again strain or the inlet stress is higher (2) In comparison with the tools needs, blower circulation is too large, so its pressure raises (3)Inlet filter is blocked, or outlet pipe is obstructed or blocked (4) Collusion or friction (stuck) rotating parts (five) The oil level is way too substantial (6) Slender V-belt is overheat, vibration is also huge, or pulley is as well tiny |
(1) Lessen the stress to the specified price (two) Exhaust the surplus gas into the ambiance or lessen the blower pace (3) Get rid of the obstructions (4)Right away shut down, check the reason (five) Modify the oil to the correct stage (6) Check the belt rigidity, and replaced it with huge diameter pulley. |
