The operating principle of the a few-blade roots blower: two a few-lobed rotors are organized in the cavity, and the
suction port and the discharge port are opened on each sides of the cavity. Via the motion 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 accomplish the
purpose of blowing.
Characteristic of our roots blower:
1. Big adjustment of the air quantity
two. Reduced Noise
three. Large performance
four. Low power cosumption
five. Long time existence
six. Reputable working, effortless servicing,modest footprint

The Application of the Roots Blower
Upkeep and inspection
(1) Check out all fasteners and locating pins situations regardless of whether they are loosening.
(two) Usually verify whether or not the leakage phenomenon of the physique.
(three) Spend consideration to lubrication, volume of grease and noises when running,
determine no matter whether it performs underneath the essential problems.
(4) CZPT & grease: The lubricant is for medium load industrial gear oil
(grade 220, kinematic viscosity of 198 ~ 242mm2 / s 40ºC, flash point ≥ 200ºC)
The grease is butter (synthetic lithium grease penetration 220-250, drop level ≥
190ºC). Replace the lubricant and grease after initial two hundred hours working, and replace
yet again right after a moth operating. Afterwards, change the lubricant and grease in accordance to the
atmosphere and lubricant (grease) high quality suggest a suitable substitute for a few
months.
(5) Always verify the inlet air filter, thoroughly clean or replace the filter in time.
(6) Blower overload sometimes not immediately exhibited, so pay out focus to
the ingestion and exhaust stress, bearing temperature and the current improve developments
of motor to determine whether or not the blower works usually
(7) Just before disassembling the blower, the assembling relation and proportions
must be recorded or calculated, make marks on components to guarantee the CZPT
requirements following assembling.
(8) When freshly equipment or overhaul, the oil tank must be cleaned before use
and suggest substitute all grease right after 8 hours working.
Widespread failure explanation and troubleshooting
No | Failure | Feasible factors | Elimination approaches |
one | Friction between the impeller |
(1) Impurities on the impeller, ensuing in the hole is too small (2) Gear use, ensuing in a massive backlash (3) The equipment is not nicely mounted, can not maintain the impeller synchronization (4) Bearing dress in ensuing in clearance growing. |
(1) Remove dust and check out whether there is damage parts (2) Change the gear hole, replace the gears if the gear backlash is greater than the regular 30% to 50% (3)Re-assemble the gears, preserve the taper make contact with region is to seventy five% (4)Change the bearing |
two | Collision between impeller and wall, the impeller prime and casing |
(1) Installation gap is not correct (2) working pressure is way too higher, exceeding the specified worth (three) Operating temperature is also high (4) Casing or foundation deformation, positioning admirer failure (five) Bearing axial spot is not good |
(1) Alter the gap (2) Discover leads to of overloading, reduced the stress to the specified benefit (three) Check out the set up accuracy and reduce the pipe stress (four) Verify and restore bearings, and to guarantee the clearance (five)Relocation |
three | Temperature way too substantial |
(one) Oil in tank is as well significantly, also thick or too soiled (2) CZPT or silencer is blocked (three)The stress is increased than the specified worth (4)Excessive put on of the impeller, huge gap (five)Very poor air flow, indoor temperature is high, ensuing in inlet air’s large temperature (6) The rotating pace is also minimal,result in the belt slipping. |
(one)Minimize the oil degree or count on oil (2)Eliminate of blocking objects (3)Minimizing the strain through the blower (4)Mend its clearance (five)Open up vents to minimize place temperature (six) Increase speed to stop the belt slipping. |
4 | Insufficient circulation |
(1) The inlet filter is blocked (2) Impeller use and the hole will increase too a lot (three) Belt slipping (four) Large imports force loss (five) CZPT ventilation leakage |
(1) Cleanse the filter dust and obstruction (2) Mend the gap (3)Tighten the belt and improve the number of belts (four)Change the inlet pressure to the specified benefit (5) Verify and mend the pipeline |
five | Oil leaking or oil leaking into the enclosure |
(1)Higher tank situation result in leakage from the discharge port (2) Seal put on, ensuing in shaft oil spills (three) The pressure is higher than the specified price |
(1)Minimize the oil level (two)Replace the seals (3)Obvious the air vents, 2mm diameter faucet is fixed in the center chamber, open up the faucet beneath the wall |
six | Irregular vibration and sound |
(1)Bearing clearance exceeds the specified value or bearing dress in (2) The gear backlash is as well large, not in a restricted set (3) The foreign objects and dust triggered by the impeller and the impeller, the impeller and the housing collision (four) the impeller shaft deformation caused the collision caused by overload, (5) Friction amongst the impeller and the inlet housing caused by overheating (6) Unbalance of the impeller induced by fouling or international physique (7) CZPT bolts or other fasteners are loosened |
(1)Substitute bearings or bearing seat (two)Reassemble gear and make sure backlash (three)Cleaning blower, check out the case is damaged (four)Check the back force, verify the wheel and adjust gap (five)Verify the filter and back pressure, enhance the hole 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 base. |
seven | Motor overload |
(1)When compared with the necessary force, the stress big difference is big that the again strain or the inlet force is large (two) When compared with the tools requirements, blower flow is way too big, so its force raises (3)Inlet filter is blocked, or outlet pipe is obstructed or blocked (4) Collusion or friction (trapped) rotating elements (five) The oil stage is way too high (6) Slender V-belt is overheat, vibration is also big, or pulley is also small |
(1) Minimize the pressure to the specified benefit (two) Exhaust the excessive fuel into the atmosphere or decrease the blower velocity (three) Take away the obstructions (four)Immediately shut down, examine the explanation (5) Adjust the oil to the appropriate stage (six) Verify the belt stress, and replaced it with big diameter pulley. |
