(1)EPTT clearance exceeds the specified worth or bearing put on (two) The EPT backlash is as well huge, not in a tigEPTT set (3) The international 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, (five) Friction between the impeller and the inlet housing induced by overheating (6) Unbalance of the impeller induced by fJCEP or foreign physique (7) Anchor bolts or other fasteners are loosened |
(one)Replace bearings or bearing seat (2)Reassemble EPT and make certain backlash (3)Cleansing blower, examine the scenario is broken (4)Verify the back force, check the wheel and change hole (five)Check the filter and again stress, enhance the gap among the impeller inlet and the casing (6)Cleanse the impeller and the casing, to make certain that the impeller clearance perform (7) Tighten the anchor bolts and leveling the foundation. |
| seven | EPT overload |
(1)In contrast with the JCEP strain, the pressure distinction is huge that the back strain or the inlet force is high (two) In comparison with the equipment requirements, blower flow is as well big, so its strain boosts (three)Inlet filter is blocked, or outlet pipe is obstructed or blocked (4) Collusion or friction (caught) rotating areas (five) The oil level is as well high (six) NEPT V-belt is overheat, vibration is way too massive, or pulley is also modest |
(1) Reduce the force to the specified value (2) Exhaust the extra gas into the environment or decrease the blower velocity (3) Get rid of the obstructions (4)Right away shut down, check out the cause (5) Alter the oil to the appropriate degree (six) Check out the belt stress, and replaced it with big diameter pulley. |
