Two stage medium consistency pulp pumping

TWO STAGE MEDIUM CONSISTENCY PULP PUMPING ABSTRACT OF THE DISCLOSURE A centrifugal pump for pumping suspensions having a consistency of about 6-20% (for example, for pumping paper pulp) has a second stage for increasing head. An auxiliary impeller is connected to the drive shaft in front of the main impeller, and upon rotation of the drive shaft directs the suspension being pumped axially into association with the main impeller. Mounted between the pump inlet and the auxiliary impeller are a plurality of stationary guide vanes, and mounted on the opposite side of the guide vanes from the auxiliary impeller are a plurality of pre-fluidizing vanes which are also connected to the drive shaft. The stationary guide vanes remove extreme pre-rotation of the suspension ahead of the auxiliary impeller, and change the turbulent and chaotic condition of the suspension into a directional flow at a definite angle of entrance. Utilizing the pump of the invention, there is no need to provide a vacuum system in order for the pump to operate properly.

Inlet casing and suction passage structure

The invention relates to a prewhirl type inlet casing for inducing a spiral stream in fluid comprising a suction passage (2) arranged on an upstream side, being orthogonal to a rotary shaft (1) of fluid machinery, and an internal passage (4) connected to the suction passage (2), the internal passage (4) being formed in a spiral shape so as to induce a swirl stream orthogonal to the rotary shaft (1) in the fluid. A guide vane (12) is provided in the fluid passage in the inlet casing. The guide vane (12) has a rectifying function capable of distributing flow rates in the swirl stream of the fluid in the internal passage (4) between the swirl center side and the swirl outer peripheral side and has a rectifying function capable of causing the fluid to deflect into the swirling direction of the swirl stream induced by the internal passage (4). With these rectifying functions, a rectified swirl stream can be easily created in the internal passage (4) so as to prevent occurrence of a deviation of a cavitations inducing zone. With this configuration, it is possible to effectively prevent occurrence of the deviation of the cavitations inducing zone in order to aim at simplifying the configuration of the internal passage (4).

A turbo machine comprising: an impeller having a plurality of blades therewith; a casing having a flow surface defined therein and being positioned with the impeller therein; and a plurality of grooves being formed in the flow surface of the casing, for connecting between an inlet side of said impeller and an area on the flow surface of the casing in which the blades of said impeller reside, on a periphery thereof, wherein an index of determining a form of the grooves is obtained by a following equation: JE No. = WR × VR × WDR × DLDR    where, WR (a width ratio) is a value obtained by dividing a total value of the groove widths W with a length of casing periphery; VR (a volume ratio) is a value obtained by dividing a total volume of said grooves with a volume of said impeller; WDR (a width-depth ratio) is a value obtained by dividing the width W of said groove with a depth D of said groove; and DLDR is a ratio between a length of said groove in flow, being lower than the impeller inlet and the depth of said groove, and wherein, said grooves are formed so that the index JE No. lies in a range from 0.03 to 0.5.
