The working basic principle 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 the two sides of the cavity. By means of the motion of a pair of
synchronous EPTs, the two rotors rotate in reverse 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.

(1)Replace bearings or bearing seat (two)Reassemble EPT and make sure backlash (three)Cleansing blower, verify the case is destroyed (four)Check out the back again strain, verify the wheel and modify gap (5)Check out the filter and again stress, enhance the hole in between the impeller inlet and the casing (6)Clean the impeller and the casing, to ensure that the impeller clearance work (7) Tighten the anchor bolts and leveling the base. |
seven | EPT overload |
(one)Compared with the JCEP force, the pressure big difference is huge that the back force or the inlet stress is large (two) In comparison with the products needs, blower movement is as well huge, so its pressure will increase (3)Inlet filter is blocked, or outlet pipe is obstructed or blocked (4) Collusion or friction (trapped) rotating areas (five) The oil level is way too substantial (6) NEPT V-belt is overheat, vibration is too massive, or pulley is as well little |
(one) Decrease the force to the specified value (two) Exhaust the extra gas into the environment or decrease the blower velocity (3) Take away the obstructions (4)Immediately shut down, check out the reason (five) Modify the oil to the appropriate degree (6) Examine the belt pressure, and changed it with large diameter pulley. |
