The main objective of the presented work is to investigate the effect of volute design on the impeller鈥搗olute interaction. Therefore a low specific speed centrifugal pump impeller has been employed and three different volutes with circ... O Litfin,A Delgado - Volume 1b, Symposia: Fluid Machi...
In this paper complex impeller of low-specific-speed inducer - centrifugal pump was studied and the calculational formula of blade number, slip factor and theoretical head were given. Finally the experimental analysis on two low-specific -speed pumps with a complex impeller were carried out and ...
there are several NSS calculators on the internet that will do the work for you. Actually, the pump manufacturer should be able to advise the NSS for all of the
Excellent anti foaming and air release properties ensure the continuity of the turbine oil lubricating oil film within the turbine. Suitable for heavy-duty steam turbine units, gas turbine units, and combined power generation units. KR68 guide rail oil A new formula, special lubricating ester, emu...
The invention relates to a hydraulic design method for a low-specific-speed overload-free centrifugal pump impeller. Geometrical parameters of the low-specific-speed centrifugal pump impeller and performance parameters of a design condition point are related together through the method of setting up ...
