The working theory of the three-blade roots blower: two three-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 motion of a pair of
synchronous EPTs, 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 gasoline in the chamber is pushed to obtain the
objective of blowing.

| six | Abnormal vibration and sound |
(1)EPTT clearance exceeds the specified benefit or bearing dress in (2) The EPT backlash is also huge, not in a tigEPTT set (three) The foreign objects and dust caused by the impeller and the impeller, the impeller and the housing collision (four) the impeller shaft deformation triggered the collision caused by overload, (5) Friction amongst the impeller and the inlet housing caused by overheating (6) Unbalance of the impeller triggered by fJCEP or foreign entire body (seven) Anchor bolts or other fasteners are loosened |
(1)Change bearings or bearing seat (two)Reassemble EPT and ensure backlash (three)Cleansing blower, check the circumstance is damaged (4)Check out the again strain, check the wheel and alter hole (five)Check the filter and back stress, enhance the gap between the impeller inlet and the casing (6)Clear the impeller and the casing, to guarantee that the impeller clearance operate (7) Tighten the anchor bolts and leveling the foundation. |
| 7 | EPT overload |
(1)When compared with the JCEP force, the pressure big difference is massive that the again pressure or the inlet force is large (two) In comparison with the gear demands, blower circulation is also big, so its stress boosts (three)Inlet filter is blocked, or outlet pipe is obstructed or blocked (four) Collusion or friction (trapped) rotating components (five) The oil level is way too large (6) NEPT V-belt is overheat, vibration is way too huge, or pulley is too little |
(1) Lessen the stress to the specified benefit (two) Exhaust the surplus gasoline into the atmosphere or lessen the blower pace (three) Remove the obstructions (4)Quickly shut down, examine the explanation (five) Modify the oil to the right level (6) Check the belt stress, and changed it with huge diameter pulley. |
