(one)EPTT clearance exceeds the specified benefit or bearing wear (two) The EPT backlash is way too large, not in a tigEPTT fastened (3) The international objects and dust caused by the impeller and the impeller, the impeller and the housing collision (four) the impeller shaft deformation induced the collision induced by overload, (five) Friction among the impeller and the inlet housing induced 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 (2)Reassemble EPT and make sure backlash (three)Cleansing blower, examine the scenario is destroyed (4)Verify the back again pressure, check out the wheel and adjust hole (five)Check out the filter and again pressure, improve the gap amongst the impeller inlet and the casing (6)Thoroughly clean the impeller and the casing, to make certain that the impeller clearance perform (7) Tighten the anchor bolts and leveling the base. |
7 | EPT overload |
(one)In comparison with the JCEP strain, the stress big difference is huge that the back strain or the inlet force is high (2) Compared with the equipment needs, blower flow is also huge, so its strain will increase (three)Inlet filter is blocked, or outlet pipe is obstructed or blocked (4) Collusion or friction (caught) rotating parts (five) The oil stage is also substantial (6) NEPT V-belt is overheat, vibration is too massive, or pulley is also tiny |
(1) Lessen the stress to the specified value (2) Exhaust the extra gasoline into the ambiance or minimize the blower speed (3) Eliminate the obstructions (four)Quickly shut down, check out the cause (5) Adjust the oil to the right degree (6) Verify the belt rigidity, and changed it with large diameter pulley. |
