(one)Exchange bearings or bearing seat (two)Reassemble EPT and make sure backlash (3)Cleaning blower, examine the case is ruined (4)Verify the again strain, verify the wheel and alter gap (5)Check the filter and back force, improve the gap among the impeller inlet and the casing (six)Clear the impeller and the casing, to guarantee that the impeller clearance perform (7) Tighten the anchor bolts and leveling the foundation. |
7 | EPT overload |
(1)When compared with the JCEP pressure, the strain big difference is large that the again pressure or the inlet strain is substantial (2) Compared with the products needs, blower stream is also big, so its force will increase (three)Inlet filter is blocked, or outlet pipe is obstructed or blocked (four) Collusion or friction (trapped) rotating areas (five) The oil stage is as well large (six) NEPT V-belt is overheat, vibration is as well massive, or pulley is also modest |
(1) Minimize the stress to the specified price (two) Exhaust the extra gas into the environment or lessen the blower speed (3) Get rid of the obstructions (four)Right away shut down, examine the cause (five) Adjust the oil to the proper degree (6) Examine the belt tension, and changed it with big diameter pulley. |
