Abstract
PURPOSE: To simplify and minimize a pump construction, manufacturing packing case and bearing case in a body, reducing the overhang, by installing a bearing to support directly the impeller.
CONSTITUTION: A seal section of the impeller ring 72 is used for a bearing, the radial force is distributed. Resin or carbon is used for bearing material at its portion, additionally plural bearings of the main shaft 11 arranged usually in a large space are manufactured to be only one 101 so that the thrust load is distributed. Consequently, the impeller under water bearing 74 arranged on the fixed side of impeller ring 72 is lubricated by circular liquid. Sealed material 91 is arranged between the under water bearing 74 and ball bearing 101. Thereby, a packing case and bearing case 10 are formed in a body, the bearing case which is an ordinary large part is eliminated, the length of shaft is shortened remarkably, the whole pump construction can be simplified and minimized.
