The functioning principle of the a few-blade roots blower: two three-lobed rotors are organized in the cavity, and the
suction port and the discharge port are opened on the two sides of the cavity. By way of the action of a pair of
synchronous EPTs, the two rotors rotate in reverse instructions 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 attain the
purpose of blowing.

(one)EPTT clearance exceeds the specified worth or bearing use (two) The EPT backlash is too big, not in a tigEPTT mounted (3) The overseas objects and dust caused by the impeller and the impeller, the impeller and the housing collision (4) the impeller shaft deformation induced the collision caused by overload, (five) Friction among the impeller and the inlet housing triggered by overheating (6) Unbalance of the impeller caused by fJCEP or overseas human body (seven) Anchor bolts or other fasteners are loosened |
(one)Substitute bearings or bearing seat (2)Reassemble EPT and guarantee backlash (three)Cleaning blower, check the circumstance is destroyed (four)Check the back strain, examine the wheel and adjust hole (5)Verify the filter and again force, enhance the gap amongst the impeller inlet and the casing (6)Cleanse the impeller and the casing, to make certain that the impeller clearance function (7) Tighten the anchor bolts and leveling the base. |
| seven | EPT overload |
(one)Compared with the JCEP strain, the pressure difference is massive that the back force or the inlet strain is high (two) When compared with the gear demands, blower stream is too massive, so its strain increases (3)Inlet filter is blocked, or outlet pipe is obstructed or blocked (four) Collusion or friction (caught) rotating elements (five) The oil stage is also high (6) NEPT V-belt is overheat, vibration is too big, or pulley is also tiny |
(one) Lessen the pressure to the specified price (two) Exhaust the excessive gasoline into the environment or minimize the blower pace (3) Remove the obstructions (4)Right away shut down, check the cause (five) Change the oil to the right degree (six) Check the belt tension, and changed it with large diameter pulley. |
