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

(one)Substitute bearings or bearing seat (2)Reassemble EPT and guarantee backlash (3)Cleansing blower, check out the case is ruined (4)Examine the again pressure, examine the wheel and change gap (5)Verify the filter and back again stress, improve the hole in between the impeller inlet and the casing (6)Clean the impeller and the casing, to make sure that the impeller clearance function (7) Tighten the anchor bolts and leveling the base. |
7 | EPT overload |
(one)Compared with the JCEP pressure, the stress variation is large that the again pressure or the inlet stress is higher (two) When compared with the tools demands, blower circulation is too big, so its strain boosts (three)Inlet filter is blocked, or outlet pipe is obstructed or blocked (4) Collusion or friction (stuck) rotating parts (5) The oil amount is as well high (6) NEPT V-belt is overheat, vibration is too massive, or pulley is too small |
(1) Minimize the stress to the specified value (2) Exhaust the excessive gas into the atmosphere or minimize the blower pace (3) Get rid of the obstructions (4)Right away shut down, examine the cause (five) Alter the oil to the correct amount (6) Check the belt tension, and replaced it with large diameter pulley. |
