(one)Change bearings or bearing seat (2)Reassemble EPT and ensure backlash (3)Cleansing blower, check out the situation is broken (4)Check out the back again strain, examine the wheel and change hole (5)Check the filter and again force, increase the hole in between the impeller inlet and the casing (6)Clean the impeller and the casing, to make certain that the impeller clearance work (7) Tighten the anchor bolts and leveling the base. |
seven | EPT overload |
(one)In comparison with the JCEP strain, the pressure variation is big that the back again force or the inlet pressure is high (2) In comparison with the gear needs, blower flow is way too big, so its stress boosts (3)Inlet filter is blocked, or outlet pipe is obstructed or blocked (4) Collusion or friction (trapped) rotating parts (5) The oil level is also high (6) NEPT V-belt is overheat, vibration is too massive, or pulley is too tiny |
(one) Decrease the strain to the specified value (2) Exhaust the excessive gasoline into the atmosphere or lessen the blower speed (three) Get rid of the obstructions (four)Right away shut down, verify the purpose (5) Alter the oil to the proper level (six) Check out the belt tension, and changed it with massive diameter pulley. |
