six | Irregular vibration and sounds |
(1)EPTT clearance exceeds the specified price or bearing use (2) The EPT backlash is too massive, 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 caused the collision induced by overload, (five) Friction amongst the impeller and the inlet housing induced by overheating (6) Unbalance of the impeller triggered by fJCEP or overseas entire body (7) Anchor bolts or other fasteners are loosened |
(1)Substitute bearings or bearing seat (two)Reassemble EPT and guarantee backlash (3)Cleaning blower, check out the scenario is damaged (four)Verify the again stress, check out the wheel and alter hole (five)Check out the filter and back again strain, increase the gap between the impeller inlet and the casing (6)Thoroughly clean the impeller and the casing, to ensure that the impeller clearance operate (seven) Tighten the anchor bolts and leveling the foundation. |
7 | EPT overload |
(one)When compared with the JCEP pressure, the stress difference is big that the back pressure or the inlet stress is higher (two) Compared with the tools specifications, blower flow is as well massive, so its stress increases (three)Inlet filter is blocked, or outlet pipe is obstructed or blocked (four) Collusion or friction (trapped) rotating areas (5) The oil amount is way too large (6) NEPT V-belt is overheat, vibration is too huge, or pulley is as well modest |
(1) Decrease the strain to the specified worth (2) Exhaust the extra gasoline into the environment or minimize the blower speed (three) Take away the obstructions (four)Right away shut down, examine the reason (five) Change the oil to the proper amount (6) Check out the belt pressure, and changed it with large diameter pulley. |
