Abstract
PURPOSE: To reduce the generation of noise by providing a self-priming circulation hole located opposite to the front end of impeller by communicating with a scroll casing, the area thereof is enlarged as proximate to the impeller.
CONSTITUTION: 4a is defining a circulation hole provided for a liner 4, which is enlarged in a taper shape toward the impeller 7, communicating coaxially with the circulation hole 2g. The circulation water passing through the circulation hole 2g is decelerated when passing through the circulation hole 4a, permitting to inject against the blade 4a of impeller 7 and causing the circulation hole 4a larger than the circulation hole 2g to reduce the noise. Besides, with the area of circulation hole 2g of pump casing 2 to have a same area of the circulation hole as a conventional pump, this enables self-priming performance and pumping-up performance to be equal to a conventional pump.
