What are the respective functions of the induction wheel, inertia wheel, and idler wheel? ? ? ?
The inducer wheel is used to reduce the net positive suction head of a centrifugal pump
Inertia wheels have a large mass and high moment of inertia, making it difficult for them to stop rotating
A idler gear is a gear that transmits torque only between two driving gears that do not come into contact with each other; it meshes with both of these gears in order to change the rotation direction of the driven gear so that it matches that of the driving gear. Since its function is merely to transmit torque and change steering without altering the gear ratio, it is called a idler wheel.
