The working principle of the 3-blade roots blower: two three-lobed rotors are organized in the cavity, and the
suction port and the discharge port are opened on the two sides of the cavity. Through the motion of a pair of
synchronous EPTs, the two rotors rotate in opposite 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 attain the
objective of blowing.

(one)EPTT clearance exceeds the specified benefit or bearing use (two) The EPT backlash is too large, not in a tigEPTT fixed (three) The overseas objects and dust triggered by the impeller and the impeller, the impeller and the housing collision (four) the impeller shaft deformation brought on the collision brought on by overload, (5) Friction in between the impeller and the inlet housing triggered by overheating (6) Unbalance of the impeller triggered by fJCEP or overseas human body (7) Anchor bolts or other fasteners are loosened |
(1)Substitute bearings or bearing seat (two)Reassemble EPT and make sure backlash (3)Cleaning blower, verify the circumstance is damaged (four)Check out the again force, check the wheel and alter hole (5)Examine the filter and again pressure, improve the hole among the impeller inlet and the casing (6)Cleanse the impeller and the casing, to guarantee that the impeller clearance work (seven) Tighten the anchor bolts and leveling the base. |
7 | EPT overload |
(one)In contrast with the JCEP pressure, the stress variation is huge that the back again strain or the inlet stress is higher (two) When compared with the gear requirements, blower flow is as well big, so its pressure boosts (3)Inlet filter is blocked, or outlet pipe is obstructed or blocked (four) Collusion or friction (stuck) rotating components (5) The oil stage is way too large (six) NEPT V-belt is overheat, vibration is too large, or pulley is way too little |
(1) Decrease the pressure to the specified benefit (two) Exhaust the surplus gasoline into the atmosphere or reduce the blower speed (three) Eliminate the obstructions (4)Instantly shut down, verify the reason (5) Adjust the oil to the appropriate amount (6) Check the belt rigidity, and replaced it with big diameter pulley. |
