Abstract

PURPOSE: To miniaturize a multistage centrifugal pump, prevent the short-circuiting between the front vortex chamber and the rear vortex chamber exactly, and securely keep the lift head and discharge amount constant even for a multistage centrifugal pump whose impellers of each stage are separately manufactured by integrally forming each impeller for two stages.
CONSTITUTION: Water is sucked in the primary side intake 2 by the rotation of the impeller 1, speeded up and compressed by the impeller 13 provided inside the primary side water path 6 between the intake 2 and the discharge portion 4, and then directed to the vortex chamber 10 of the casing 8. And, it goes through the discharge pipe 12 and the secondary side intake 3 of the impeller 1 to the discharge portion 5, and then discharge through the vortex chamber 11 of the casing 9 and the discharge port of the housing 20. On the other hand, during the rotation of the impeller 1, the inside circumference of the sealing material 15 cut off from an annular along a cutting line comes into contact with the inner surface of the groove 16 in a sliding manner and also the other surface comes into contact with the tiered surface 17 of the impeller 1 likewise, whereby preventing the short-circuiting of water between both the vortex chambers 10 and 11. Thus, the lift head and discharge amount of the multistage centrifugal pump can be kept securely.
