The functioning 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. By means of the action 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 fuel in the chamber is pushed to achieve the
goal of blowing.
Feature of our roots blower:
1. Big adjustment of the air volume
2. Minimal Noise
three. Large performance
4. Low strength cosumption
5. Prolonged time life

The Software of the Roots Blower
Upkeep and inspection
(1) Check out all fasteners and finding pins situations whether or not they are loosening.
(two) Always check whether the leakage phenomenon of the body.
(three) Pay focus to lubrication, volume of grease and noises when operating,
figure out whether or not it works under the needed circumstances.
(4) CZPT & grease: The lubricant is for medium load industrial equipment oil
(quality 220, kinematic viscosity of 198 ~ 242mm2 / s 40ºC, flash stage ≥ 200ºC)
The grease is butter (synthetic lithium grease penetration 220-250, drop position ≥
190ºC). Exchange the lubricant and grease right after initial 200 hours managing, and substitute
yet again following a moth operating. Afterwards, substitute the lubricant and grease in accordance to the
environment and lubricant (grease) good quality suggest a ideal substitute for a few
months.
(5) Usually check the inlet air filter, thoroughly clean or substitute the filter in time.
(six) Blower overload often not quickly exhibited, so shell out attention to
the consumption and exhaust pressure, bearing temperature and the current boost developments
of motor to decide no matter whether the blower performs normally
(seven) Ahead of disassembling the blower, the assembling relation and dimensions
have to be recorded or measured, make marks on components to ensure the CZPT
needs right after assembling.
(8) When newly equipment or overhaul, the oil tank need to be cleaned ahead of use
and propose substitute all grease after eight several hours managing.
Common failure explanation and troubleshooting
No | Failure | Attainable reasons | Elimination methods |
1 | Friction in between the impeller |
(1) Impurities on the impeller, resulting in the gap is as well tiny (2) Equipment wear, resulting in a big backlash (three) The equipment is not effectively fastened, can not preserve the impeller synchronization (4) Bearing dress in ensuing in clearance escalating. |
(one) Get rid of grime and check whether there is harm areas (two) Modify the equipment hole, change the gears if the equipment backlash is increased than the average 30% to fifty% (three)Re-assemble the gears, maintain the taper contact area is to 75% (4)Change the bearing |
2 | Collision in between impeller and wall, the impeller prime and casing |
(one) Installation gap is not proper (two) running pressure is as well higher, exceeding the specified worth (three) Running temperature is too large (four) Casing or base deformation, positioning supporter failure (5) Bearing axial spot is not great |
(one) Modify the hole (two) Recognize triggers of overloading, diminished the force to the specified worth (three) Examine the set up accuracy and minimize the pipe rigidity (four) Verify and fix bearings, and to ensure the clearance (5)Relocation |
3 | Temperature also substantial |
(1) Oil in tank is as well much, way too thick or as well filthy (2) CZPT or silencer is blocked (three)The pressure is increased than the specified value (4)Abnormal wear of the impeller, large gap (5)Inadequate ventilation, indoor temperature is large, ensuing in inlet air’s large temperature (6) The rotating velocity is way too minimal,end result in the belt slipping. |
(one)Reduce the oil amount or count on oil (2)Remove of blocking objects (3)Reducing the stress by way of the blower (4)Repair its clearance (5)Open up vents to decrease room temperature (6) Improve speed to avert the belt slipping. |
4 | Inadequate movement |
(one) The inlet filter is blocked (two) Impeller wear and the hole will increase as well a lot (three) Belt slipping (four) Big imports stress reduction (five) CZPT air flow leakage |
(one) Cleanse the filter dust and obstruction (two) Repair the hole (3)Tighten the belt and boost the amount of belts (four)Change the inlet stress to the specified price (5) Verify and fix the pipeline |
5 | Oil leaking or oil leaking into the enclosure |
(1)Higher tank placement trigger leakage from the discharge port (2) Seal use, resulting in shaft oil spills (3) The pressure is increased than the specified value |
(1)Decrease the oil amount (two)Substitute the seals (three)Clear the air vents, 2mm diameter faucet is set in the middle chamber, open the faucet underneath the wall |
six | Abnormal vibration and sound |
(1)Bearing clearance exceeds the specified worth or bearing use (2) The gear backlash is also massive, not in a tight fixed (3) The foreign objects and dust triggered 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 brought on by overheating (6) Unbalance of the impeller brought on by fouling or overseas human body (seven) CZPT bolts or other fasteners are loosened |
(one)Change bearings or bearing seat (two)Reassemble gear and make sure backlash (3)Cleansing blower, verify the case is broken (4)Check the again strain, verify the wheel and alter hole (five)Examine the filter and back again force, increase the gap among the impeller inlet and the casing (six)Cleanse the impeller and the casing, to guarantee that the impeller clearance work (7) Tighten the anchor bolts and leveling the foundation. |
7 | Motor overload |
(one)When compared with the essential force, the stress difference is big that the again force or the inlet pressure is large (2) In contrast with the tools requirements, blower circulation is too massive, so its pressure will increase (3)Inlet filter is blocked, or outlet pipe is obstructed or blocked (four) Collusion or friction (caught) rotating parts (5) The oil stage is also substantial (six) Slender V-belt is overheat, vibration is way too huge, or pulley is way too little |
(one) Minimize the stress to the specified benefit (two) Exhaust the extra fuel into the environment or lessen the blower velocity (three) Remove the obstructions (four)Right away shut down, examine the cause (5) Alter the oil to the right stage (six) Verify the belt stress, and changed it with big diameter pulley. |
