Abstract：According to the blade regulation method and power transmission mode, the structure of bulb tubular pumps installed in the first phase of South-to-North Water Diversion Eastern Route Project in China can be classified into four kinds, i.e. compact structure with variable frequency drives(VFD)(type Ⅰ), dismountable structure with VFD(type Ⅱ), dismountable structure with gearbox power transmission chain and mechanical blade regulation mechanism(type Ⅲ), and dismountable structure with hydraulic blade regulation mechanism(type Ⅳ). Based on the blade regulation method, pump operational condition adjusting approach and power transmission chain, the major advantages and disadvantages of these structures are analyzed qualitatively and quantitatively. The result shows that even though all the four kinds of pump structure are safe and reliable, in which the maximum deformation of type Ⅳ is about 0.2 mm and the deformation differences between various locations is less than 0.1 mm under the positive and negative peak axial thrust conditions, there are some notable differences in the structure features. For instance, the weight of type Ⅳ unit is 225 t, about three times type Ⅰ. Compared with the mechanical blade regulation method, the structure with VFD is simple, but also a cylindrical hub can be adopted in the pumps, so that the pump efficiency can be improved by over 1.6%.
