The functioning theory of the 3-blade roots blower: two 3-lobed rotors are arranged in the cavity, and the
suction port and the discharge port are opened on equally sides of the cavity. By way of 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 achieve the
goal of blowing.

(one)Exchange bearings or bearing seat (2)Reassemble EPT and make certain backlash (three)Cleaning blower, verify the situation is destroyed (four)Examine the back strain, examine the wheel and modify gap (5)Check the filter and back again pressure, increase the gap in between the impeller inlet and the casing (six)Cleanse the impeller and the casing, to make sure that the impeller clearance operate (seven) Tighten the anchor bolts and leveling the foundation. |
7 | EPT overload |
(1)When compared with the JCEP force, the force big difference is huge that the back again pressure or the inlet stress is large (two) In contrast with the products demands, blower flow is as well massive, so its strain raises (three)Inlet filter is blocked, or outlet pipe is obstructed or blocked (four) Collusion or friction (caught) rotating areas (five) The oil degree is as well substantial (six) NEPT V-belt is overheat, vibration is way too large, or pulley is as well tiny |
(1) Minimize the pressure to the specified price (two) Exhaust the surplus fuel into the ambiance or lessen the blower pace (3) Remove the obstructions (4)Instantly shut down, examine the explanation (five) Modify the oil to the appropriate amount (six) Verify the belt rigidity, and replaced it with huge diameter pulley. |
