(one)Change bearings or bearing seat (2)Reassemble EPT and make sure backlash (three)Cleansing blower, check the scenario is ruined (four)Verify the back again pressure, examine the wheel and modify hole (five)Examine the filter and again pressure, improve the gap amongst the impeller inlet and the casing (six)Cleanse the impeller and the casing, to ensure that the impeller clearance work (seven) Tighten the anchor bolts and leveling the foundation. |
seven | EPT overload |
(1)Compared with the JCEP force, the pressure big difference is large that the again pressure or the inlet pressure is large (two) In comparison with the tools needs, blower movement is also massive, so its strain raises (three)Inlet filter is blocked, or outlet pipe is obstructed or blocked (four) Collusion or friction (caught) rotating elements (five) The oil stage is as well large (6) NEPT V-belt is overheat, vibration is also massive, or pulley is as well modest |
(1) Lessen the force to the specified worth (2) Exhaust the extra gas into the atmosphere or decrease the blower pace (three) Eliminate the obstructions (4)Instantly shut down, check out the purpose (five) Change the oil to the right stage (six) Verify the belt rigidity, and replaced it with large diameter pulley. |
