Spiral Pump and Manufacturing Method Therefor

摘要

The present invention relates to a spiral pump, including a support body; at least one or more substantially rigid rotary parts that are rotatable relative to said support body, wherein said one or more rotary parts comprise at least one integrated spiral fluid channel that has an inlet for receiving fluid arranged at or near the outer radial wall of said one or more rotary parts and an outlet for discharging fluid at an increased pressure at or near its rotary axis; wherein a fluid passage, configured for passing fluid at the increased pressure from inside the one or more rigid rotary parts to outside the one or more rigid rotary parts, is arranged at or near the rotary axis; and drive means for rotatably driving the one or more rotary parts. The invention further relates to a manufacturing method for such a spiral pump.
