The working 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 equally sides of the cavity. By means 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 gas in the chamber is pushed to attain the
objective of blowing.

The Application of the Roots Blower
Maintenance and inspection
(1) Check all fasteners and finding pins problems whether they are loosening.
(two) Usually check out whether the leakage phenomenon of the body.
(three) Spend interest to lubrication, amount of grease and noises when operating,
decide whether or not it operates under the required circumstances.
(4) CZPT & grease: The lubricant is for medium load industrial gear oil
(quality 220, kinematic viscosity of 198 ~ 242mm2 / s 40ºC, flash stage ≥ 200ºC)
The grease is butter (synthetic lithium grease penetration 220-250, fall stage ≥
190ºC). Exchange the lubricant and grease soon after initial 200 several hours managing, and exchange
yet again following a moth working. Later, replace the lubricant and grease in accordance to the
setting and lubricant (grease) top quality propose a suitable substitution for three
months.
(5) Constantly examine the inlet air filter, clear or substitute the filter in time.
(six) Blower overload often not instantly exhibited, so pay attention to
the intake and exhaust force, bearing temperature and the current enhance tendencies
of motor to determine whether the blower operates generally
(7) Just before disassembling the blower, the assembling relation and proportions
should be recorded or measured, make marks on components to ensure the CZPT
specifications right after assembling.
(eight) When newly device or overhaul, the oil tank must be cleaned prior to use
and propose exchange all grease soon after eight hours managing.
Widespread failure reason and troubleshooting
No | Failure | Achievable factors | Elimination methods |
1 | Friction in between the impeller |
(1) Impurities on the impeller, resulting in the hole is way too small (2) Gear wear, ensuing in a large backlash (3) The equipment is not effectively fixed, can not maintain the impeller synchronization (four) Bearing dress in resulting in clearance escalating. |
(1) Get rid of dirt and check no matter whether there is injury parts (2) Alter the equipment gap, exchange the gears if the equipment backlash is higher than the average thirty% to 50% (3)Re-assemble the gears, hold the taper make contact with region is to seventy five% (four)Substitute the bearing |
two | Collision between impeller and wall, the impeller prime and casing |
(1) Set up hole is not appropriate (2) operating stress is too higher, exceeding the specified worth (3) Operating temperature is as well substantial (4) Casing or foundation deformation, positioning enthusiast failure (5) Bearing axial place is not very good |
(one) Alter the gap (2) Recognize triggers of overloading, decreased the strain to the specified value (3) Check the installation precision and lessen the pipe pressure (4) Check and restore bearings, and to ensure the clearance (5)Relocation |
three | Temperature way too large |
(one) Oil in tank is way too significantly, too thick or way too dirty (2) CZPT or silencer is blocked (3)The stress is larger than the specified value (4)Too much wear of the impeller, large gap (5)Poor air flow, indoor temperature is substantial, resulting in inlet air’s high temperature (6) The rotating pace is way too low,outcome in the belt slipping. |
(1)Reduce the oil level or rely on oil (2)Take away of blocking objects (three)Lowering the stress via the blower (4)Mend its clearance (five)Open vents to decrease place temperature (6) Boost velocity to avoid the belt slipping. |
4 | Inadequate stream |
(1) The inlet filter is blocked (2) Impeller use and the gap raises way too significantly (3) Belt slipping (4) Massive imports force decline (five) CZPT ventilation leakage |
(one) Clean the filter dust and obstruction (2) Restore the gap (3)Tighten the belt and increase the number of belts (4)Modify the inlet strain to the specified worth (5) Verify and fix the pipeline |
five | Oil leaking or oil leaking into the enclosure |
(one)Large tank situation lead to leakage from the discharge port (two) Seal use, resulting in shaft oil spills (3) The stress is greater than the specified price |
(one)Lessen the oil degree (2)Replace the seals (3)Distinct the air vents, 2mm diameter faucet is fastened in the middle chamber, open the faucet beneath the wall |
six | Abnormal vibration and noise |
(1)Bearing clearance exceeds the specified price or bearing dress in (2) The equipment backlash is too massive, not in a restricted fastened (3) The overseas objects and dust induced by the impeller and the impeller, the impeller and the housing collision (4) the impeller shaft deformation brought on the collision triggered by overload, (5) Friction among the impeller and the inlet housing triggered by overheating (six) Unbalance of the impeller induced by fouling or overseas physique (seven) CZPT bolts or other fasteners are loosened |
(1)Change bearings or bearing seat (2)Reassemble gear and make certain backlash (3)Cleaning blower, examine the circumstance is damaged (four)Check the again stress, examine the wheel and modify gap (five)Examine the filter and back force, improve the gap in between the impeller inlet and the casing (six)Thoroughly clean the impeller and the casing, to ensure that the impeller clearance perform (7) Tighten the anchor bolts and leveling the base. |
seven | Motor overload |
(1)In comparison with the essential force, the strain big difference is big that the back again strain or the inlet stress is substantial (2) In comparison with the tools needs, blower circulation is also large, so its stress boosts (three)Inlet filter is blocked, or outlet pipe is obstructed or blocked (four) Collusion or friction (caught) rotating components (five) The oil level is as well large (six) Slim V-belt is overheat, vibration is as well large, or pulley is as well little |
(1) Minimize the stress to the specified price (2) Exhaust the excessive gas into the environment or reduce the blower speed (3) Take away the obstructions (4)Quickly shut down, check out the cause (five) Adjust the oil to the proper level (6) Examine the belt stress, and changed it with massive diameter pulley. |
