| 摘要 |
For mixing and conveying of highly viscous fluids, the invention provides a single-stage or multi-stage axial centrifugal pump to which the components to be mixed are fed through lateral connections (10, 12) in front of the first rotor (FIG. 1). The blades (4, 4') of the or of each rotor (FIG. 2) have at least one hole (5). The lateral connections (10, 12) have at least one mixing nozzle (12) with several holes (13). The pump housing consists of two parts. Fixed guide blades (2, 2') are provided in the lower part (1), out of which the upper part (5) together with rotor shaft (3), its bearings (7, 8) and the rotors can be lifted. A relief and control opening (15) is provided above a gasket (14) which separates the upper part (5) from the inside of the pump.
