(1)EPTT clearance exceeds the specified benefit or bearing wear (2) The EPT backlash is also massive, not in a tigEPTT set (three) The overseas objects and dust induced by the impeller and the impeller, the impeller and the housing collision (four) the impeller shaft deformation triggered the collision induced by overload, (5) Friction amongst the impeller and the inlet housing triggered by overheating (six) Unbalance of the impeller induced by fJCEP or foreign entire body (7) Anchor bolts or other fasteners are loosened |
(1)Substitute bearings or bearing seat (two)Reassemble EPT and guarantee backlash (three)Cleansing blower, check out the situation is broken (four)Check out the again strain, check the wheel and alter gap (five)Verify the filter and again pressure, increase the gap between the impeller inlet and the casing (6)Thoroughly clean the impeller and the casing, to make certain that the impeller clearance work (seven) Tighten the anchor bolts and leveling the foundation. |
| seven | EPT overload |
(one)When compared with the JCEP stress, the strain distinction is huge that the back stress or the inlet stress is higher (two) When compared with the gear requirements, blower flow is as well large, so its strain boosts (3)Inlet filter is blocked, or outlet pipe is obstructed or blocked (4) Collusion or friction (caught) rotating components (5) The oil level is too substantial (6) NEPT V-belt is overheat, vibration is as well big, or pulley is also little |
(one) Minimize the pressure to the specified worth (2) Exhaust the extra fuel into the environment or reduce the blower speed (three) Remove the obstructions (four)Right away shut down, examine the explanation (5) Change the oil to the appropriate amount (six) Examine the belt stress, and replaced it with large diameter pulley. |
