The working theory 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 both sides of the cavity. Via the motion 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 achieve the
function of blowing.

(1)EPTT clearance exceeds the specified benefit or bearing put on (two) The EPT backlash is too massive, not in a tigEPTT set (three) The international objects and dust induced by the impeller and the impeller, the impeller and the housing collision (four) the impeller shaft deformation induced the collision induced by overload, (5) Friction between the impeller and the inlet housing caused by overheating (6) Unbalance of the impeller caused by fJCEP or international body (7) Anchor bolts or other fasteners are loosened |
(1)Exchange bearings or bearing seat (2)Reassemble EPT and make certain backlash (3)Cleansing blower, examine the case is destroyed (four)Examine the again force, examine the wheel and adjust hole (five)Examine the filter and back again stress, increase the gap amongst the impeller inlet and the casing (6)Clear the impeller and the casing, to make sure that the impeller clearance perform (seven) Tighten the anchor bolts and leveling the foundation. |
7 | EPT overload |
(1)In comparison with the JCEP strain, the stress difference is large that the back again pressure or the inlet stress is higher (two) In contrast with the products needs, blower flow is also huge, so its stress increases (3)Inlet filter is blocked, or outlet pipe is obstructed or blocked (four) Collusion or friction (caught) rotating elements (five) The oil degree is way too substantial (six) NEPT V-belt is overheat, vibration is way too huge, or pulley is also tiny |
(one) Lessen the pressure to the specified value (2) Exhaust the surplus fuel into the atmosphere or reduce the blower speed (3) Remove the obstructions (4)Instantly shut down, check out the cause (5) Alter the oil to the right degree (six) Check the belt rigidity, and changed it with big diameter pulley. |
