(one)Change bearings or bearing seat (two)Reassemble EPT and guarantee backlash (three)Cleaning blower, check out the scenario is damaged (4)Examine the again force, check out the wheel and change gap (five)Check the filter and again strain, boost the gap between the impeller inlet and the casing (six)Thoroughly clean the impeller and the casing, to ensure that the impeller clearance function (7) Tighten the anchor bolts and leveling the base. |
seven | EPT overload |
(1)Compared with the JCEP force, the force distinction is massive that the back again pressure or the inlet force is substantial (2) In contrast with the products demands, blower circulation is as well huge, so its force will increase (3)Inlet filter is blocked, or outlet pipe is obstructed or blocked (four) Collusion or friction (caught) rotating parts (5) The oil level is way too substantial (six) NEPT V-belt is overheat, vibration is also big, or pulley is also small |
(one) Lessen the stress to the specified price (2) Exhaust the surplus gas into the environment or decrease the blower speed (three) Take away the obstructions (4)Immediately shut down, check the purpose (5) Change the oil to the right level (six) Verify the belt stress, and replaced it with huge diameter pulley. |
