Title:
SELF-PRIMING LIFTING PUMP DIRECTLY CONNECTED TO ENGINE AND HAVING LARGE CAPACITY SUCTION FORCE
Document Type and Number:
WIPO Patent Application WO/2014/088126
Kind Code:
A1
Abstract:
The self-priming lifting pump directly connected to an engine and having large capacity suction force according to the present invention is configured in that a spiral vortex flow chamber is formed on one side of a pump housing, an impeller is arranged in the vortex flow chamber, a curved inlet pipeline is formed between an inlet unit and a water inlet pipe on one side of the pump housing, an expansion pipeline is formed between an outlet unit of the impeller and a water outlet pipe such that the cross sectional surface of the expansion pipeline increases from an outlet point of the vortex flow chamber to the water outlet pipe, and a flow adjusting means screwed to the front surface of an outlet of the curved inlet pipeline is further arranged in the inlet unit of the impeller and in the outlet of the curved inlet pipeline so as to adjust the flow rate flowing from the water inlet pipe to the inlet unit of the impeller. Thus, the lifting pump of the present invention has excellent advantages in that the lifting pump having a differential pressure space therein operates with impellers at mid and low speed RPM by the power of an internal combustion engine in a river or reservoir so as to provide large capacity function force, thus enabling high capacity suction head per hour and performing high capacity pumping operation in a stable and smooth manner.
