The operating principle of the a few-blade roots blower: two 3-lobed rotors are organized in the cavity, and the
suction port and the discharge port are opened on both sides of the cavity. Through the action of a pair of
synchronous EPTs, the two rotors rotate in opposite directions and Relying on the mutual engagement of the two
rotors, the suction port and the discharge port are isolated, and the fuel in the chamber is pushed to accomplish the
goal of blowing.

(one)Substitute bearings or bearing seat (two)Reassemble EPT and ensure backlash (3)Cleansing blower, verify the case is ruined (four)Examine the back again strain, check out the wheel and adjust gap (five)Check the filter and back again pressure, enhance the gap among the impeller inlet and the casing (6)Clean the impeller and the casing, to guarantee that the impeller clearance work (seven) Tighten the anchor bolts and leveling the foundation. |
7 | EPT overload |
(1)Compared with the JCEP stress, the strain variation is huge that the back force or the inlet strain is large (2) In comparison with the gear requirements, blower flow is as well big, so its force increases (3)Inlet filter is blocked, or outlet pipe is obstructed or blocked (four) Collusion or friction (stuck) rotating elements (five) The oil amount is as well large (six) NEPT V-belt is overheat, vibration is as well huge, or pulley is also little |
(1) Decrease the force to the specified benefit (two) Exhaust the extra fuel into the atmosphere or lessen the blower speed (3) Remove the obstructions (four)Instantly shut down, verify the purpose (five) Alter the oil to the right level (six) Check out the belt stress, and replaced it with massive diameter pulley. |
