Quasi 3-D Flow Design and Characteristics of Diagonal Flow Impeller with Circular Arc Plate
Basing on the principle of virtual equivalent velocity, this paper adapt the method of extending axis flow impeller to the quasi 3-D flow design of diagonal flow impeller with the experimental cascade data of circular arc blade. The performances of diagonal flow fan with outlet guide volute designed by this method, are compared with that designed by airfoil section cascade data. The reasonablen...
متن کاملImpeller and volute design and optimization of the centrifugal pump with low specific speed in order to extract performance curves
Now a day centrifugal pumps are vital components of industries. Certainly, one of the most important specifications of centrifugal pumps are the performance curves. In the present work, performance curves of a centrifugal pumps are obtained by Computational fluid dynamics (CFD) and as an outcome, CFD results compare by practical curves. At the first step impeller and volute are designed with tw...
متن کاملInvestigation into Influence of Inlet Prewhirl on Flow Field of Diagonal Impeller with Exit Guide Volute
By means of setting inlet pre-rotator ,the inlet and exit flow field of the diagonal flow impeller with exit guide volute have been measured with 5 holes probe, in different flow conditions, and in the conditions of positive and negative pre-rotating. The expe1iment results are compared with that of without the pre-rotator.
متن کاملInfluence of Impeller Suction Specific Speed on Vibration Performance
The most commonly used hard limitation for pump suction specific speed is 11,000 (US units). This hard limit grew out of the recommendations from a 1982 reliability study by J.L. Hallam (Hallam 1982). Concomitant testing of the vibration performance of an OH2 4x6-11 pump was made with impellers designed for different suction specific speeds (Lobanoff and Ross 1985). This study showed that all t...
متن کاملOptimal Design Schemes of Centrifugal Pump Compound Impeller at Super-Low Specific Speed
The paper has established sixteen design schemes for super-low specific speed centrifugal pump compound impeller with orthogonal method, based on the main factors impacting the design of compound impeller, like short blades number of compound impeller, the relative position of blade radial inlet, blade circumferential bias degree, deflection angle, etc.,. By numerical simulation, the optimal de...
