Efficient and compact type self-sucking and double-sucking pump

Abstract

The invention relates to an efficient and compact type self-sucking and double-sucking pump. The efficient and compact type self-sucking and double-sucking pump comprises a pump body (1) and a double-sucking impeller (2) arranged in the pump body (1). An impeller working cavity is formed in the middle of the interior of the pump body (1). Two corresponding water inlet grooves (6) are formed in thetwo sides of the impeller working cavity. Water sucking openings are formed in the two sides of the impeller working cavity, wherein each water sucking opening communicates with the corresponding water inlet groove (6). The double-sucking impeller (2) is arranged in the impeller working cavity by being matched with the water sucking openings in the impeller working cavity through a sealing ring (24) arranged at the edge of the water outlet side of a blade set (23) of the double-sucking impeller. An impeller pump shaft mounting opening (8) is formed in the position, corresponding to the watersucking openings in the impeller working cavity, on one side wall of the pump body (1). The efficient and compact type self-sucking and double-sucking pump adopts an integral pump body structure, single shaft extending end disassembling and assembling can be achieved, and a self-sucking function is achieved, so that miniaturization of the double-sucking pump and wide applicability of the working environment are realized.

Description

technical field [0001] The invention relates to a double-suction pump, in particular to an efficient and compact self-priming double-suction pump. Background technique [0002] As an important form of centrifugal pumps, double-suction pumps have the advantages of large flow, high efficiency, and maximum balance of axial push-pull forces compared with single-suction pumps. However, the seal rings of the double-suction impeller of the double-suction pump are all arranged on the two water inlet sides of the double-suction impeller at present, so the pump body of the double-suction pump must adopt a split pump body. This kind of structure is complex, costly, bulky, and cannot be miniaturized, so the current use of double-suction pumps is relatively limited, and is generally used in large and medium-sized projects with fixed operations and urban water supply and drainage. Contents of the invention [0003] The present invention is to provide a compact self-priming double-sucti...

However, at present, the sealing rings of the double-suction impeller of the double-suction pump are all set on the two water inlet sides of the double-suction impeller, so the pump body of the double-suction pump must adopt a split pump body

This kind of structure is complex, costly, bulky, and cannot be miniaturized, so the current use of double-suction pumps is relatively limited, and is generally used in large and medium-sized projects with fixed operations and urban water supply and drainage.
