Abstract
A self-cooling, wear-resistance, non-leakage double-suction pump relates to a centrifugal vane pump and mainly solves the problem of the short service life of an overflowing part and the leakage of a shaft seal. A pump shaft and a rotor which consists of a pump shaft, an impeller, a shaft sleeve and a seal shaft sleeve, etc. are mounted in the left bearing seat and the right bearing seat. The pump shell consists of a pump body and a pump lid. The double-suction pump is characterized in that the overflow part thereof uses a wear-resistant material and the shaft seal uses a mechanical seal. A cooling pipe which is connected with the inlet of the double-suction pump enters a mechanical sealed cavity, the outsides of the two cover plates of the impeller are provided with a back blade and a spacer ring is arranged between two shafts at two ends of the rotor. The utility model effectively improves the service life of the overflow part, solves the leakage problem of the shaft seal and achieves the self-cooling of the mechanical seal.
