The functioning theory of the three-blade roots blower: two 3-lobed rotors are organized in the cavity, and the
suction port and the discharge port are opened on equally sides of the cavity. Via 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
function of blowing.

(1)Exchange bearings or bearing seat (two)Reassemble EPT and guarantee backlash (3)Cleansing blower, verify the circumstance is destroyed (4)Check the back stress, examine the wheel and adjust hole (five)Check the filter and back stress, increase the gap between the impeller inlet and the casing (6)Cleanse the impeller and the casing, to guarantee that the impeller clearance operate (7) Tighten the anchor bolts and leveling the base. |
seven | EPT overload |
(1)In comparison with the JCEP force, the pressure distinction is huge that the back pressure or the inlet stress is higher (2) In contrast with the equipment needs, blower flow is too massive, so its strain increases (3)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 substantial (6) NEPT V-belt is overheat, vibration is too large, or pulley is as well small |
(1) Decrease the stress to the specified price (two) Exhaust the extra gasoline into the environment or minimize the blower pace (three) Remove the obstructions (4)Quickly shut down, verify the cause (five) Modify the oil to the proper degree (6) Check the belt pressure, and changed it with large diameter pulley. |
