Propelling Style\Lobate
Propelling Style:
Normal rotating condition:n=100-500rpm,v=3-15m/s
Viscosity range of normal mediator:<2000(centipoise)
Flowage: axial flow type, circulate speed rate, small shear force. Step-board or guide shell is used to strengthen the axial circulating.
Lobate:
There are two kinds of plain and hinge.
Normal operation term: n=1-100rpm v=1.0-5.0m/s
Normal range of viscosity of mediator:<2000(centipoise)
Flowage:(1) Plain blades£ºmainly horizontal circumferential flow in low speed,runoff type is in high speed; up and down flow occurs when damper is put.
(2)Hinge:there are axial flow,runoff flow and circumferential flow. It is mainly operated in laminar current and transition flow. |
