The operating theory of the 3-blade roots blower: two three-lobed rotors are arranged in the cavity, and the
suction port and the discharge port are opened on both sides of the cavity. By means of the action of a pair of
synchronous EPTs, the two rotors rotate in opposite instructions and Relying on the mutual engagement of the two
rotors, the suction port and the discharge port are isolated, and the gas in the chamber is pushed to attain the
goal of blowing.

(1)Replace bearings or bearing seat (two)Reassemble EPT and make certain backlash (3)Cleansing blower, examine the situation is ruined (four)Verify the back again stress, examine the wheel and alter hole (five)Examine the filter and back strain, increase the hole amongst the impeller inlet and the casing (6)Clean the impeller and the casing, to guarantee that the impeller clearance perform (7) Tighten the anchor bolts and leveling the base. |
seven | EPT overload |
(one)Compared with the JCEP pressure, the pressure variation is large that the again pressure or the inlet force is higher (2) In contrast with the gear specifications, blower stream is way too huge, so its pressure raises (3)Inlet filter is blocked, or outlet pipe is obstructed or blocked (four) Collusion or friction (stuck) rotating parts (five) The oil level is way too high (6) NEPT V-belt is overheat, vibration is too massive, or pulley is also small |
(one) Minimize the pressure to the specified price (2) Exhaust the excessive gas into the environment or lessen the blower velocity (three) Eliminate the obstructions (four)Instantly shut down, examine the explanation (five) Change the oil to the proper degree (6) Check the belt stress, and changed it with large diameter pulley. |
