The functioning basic principle of the three-blade roots blower: two a few-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 gasoline in the chamber is pushed to accomplish the
objective of blowing.

(one)EPTT clearance exceeds the specified benefit or bearing put on (two) The EPT backlash is also large, not in a tigEPTT set (3) The international objects and dust caused by the impeller and the impeller, the impeller and the housing collision (four) the impeller shaft deformation brought on the collision induced by overload, (five) Friction in between the impeller and the inlet housing brought on by overheating (6) Unbalance of the impeller induced by fJCEP or international body (seven) Anchor bolts or other fasteners are loosened |
(1)Replace bearings or bearing seat (2)Reassemble EPT and guarantee backlash (three)Cleaning blower, check out the situation is destroyed (four)Check the again stress, check out the wheel and alter hole (5)Check the filter and back force, increase the hole among the impeller inlet and the casing (six)Thoroughly clean the impeller and the casing, to make certain that the impeller clearance work (seven) Tighten the anchor bolts and leveling the base. |
| 7 | EPT overload |
(1)When compared with the JCEP force, the force distinction is large that the back again force or the inlet strain is higher (two) In comparison with the gear specifications, blower stream is way too massive, so its force raises (3)Inlet filter is blocked, or outlet pipe is obstructed or blocked (4) Collusion or friction (stuck) rotating parts (5) The oil stage is way too substantial (6) NEPT V-belt is overheat, vibration is way too big, or pulley is too modest |
(one) Decrease the force to the specified benefit (two) Exhaust the excessive gas into the ambiance or reduce the blower pace (three) Remove the obstructions (4)Right away shut down, check out the cause (5) Change the oil to the appropriate stage (6) Check the belt pressure, and replaced it with massive diameter pulley. |
