PUMP INSTALLATION Russian patent published in 1995 - IPC

FIELD: pump engineering. SUBSTANCE: working member having the inlet and outlet is mounted for permitting rotation about horizontal axis. The member is made of a sheet material secured to the rigid frame and rolled into a spiral to provide a spaced relation between turns. The end faces of the turns are tightly interconnected by way of side walls. The port, which is defined at the periphery of the spiral by the side walls and surfaces of the last and last but one turns of the spiral, serves as the inlet of the member. The blades are mounted on the outside surface of the member. The pipe with the ports is symmetrically mounted inside the member. The hydraulic assembly constructed as a turbine is housed in the pipe. The electric generator is mounted on the same shaft as the turbine and separates the pipe into two parts. The ends of the pipe form the outlet. The parts of the pipe are in communication with the inner space of the member through the ports, the one of the parts being connected directly and the other one through the turbine. EFFECT: enhanced efficiency. 5 cl, 5 dwg
