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

(1)EPTT clearance exceeds the specified price or bearing dress in (2) The EPT backlash is as well big, not in a tigEPTT mounted (three) The international objects and dust brought on by the impeller and the impeller, the impeller and the housing collision (four) the impeller shaft deformation induced the collision induced by overload, (five) Friction in between the impeller and the inlet housing triggered by overheating (6) Unbalance of the impeller triggered by fJCEP or foreign physique (seven) Anchor bolts or other fasteners are loosened |
(1)Substitute bearings or bearing seat (two)Reassemble EPT and guarantee backlash (3)Cleansing blower, examine the scenario is destroyed (4)Verify the again strain, check the wheel and modify hole (five)Check out the filter and back pressure, boost the gap amongst the impeller inlet and the casing (6)Cleanse the impeller and the casing, to guarantee that the impeller clearance work (seven) Tighten the anchor bolts and leveling the foundation. |
| seven | EPT overload |
(1)Compared with the JCEP pressure, the pressure variation is massive that the back pressure or the inlet stress is large (two) In contrast with the tools specifications, blower circulation is way too massive, so its strain will increase (three)Inlet filter is blocked, or outlet pipe is obstructed or blocked (four) Collusion or friction (caught) rotating elements (five) The oil degree is also large (six) NEPT V-belt is overheat, vibration is also big, or pulley is too little |
(one) Reduce the strain to the specified value (two) Exhaust the extra fuel into the atmosphere or decrease the blower speed (3) Eliminate the obstructions (4)Quickly shut down, examine the explanation (5) Alter the oil to the appropriate level (6) Check out the belt rigidity, and replaced it with big diameter pulley. |
