The purpose of this utility model is to realize like this, new side is stretched tubular pump to the S oblique crank Z, comprise the water inlet flow channel that connects successively, the pump section, the bend loss of outlet passage, the straight of outlet passage expanded section and drives the power plant that are connected impeller rotation in the pump section, it is characterized in that, the smooth-going connection of pump impeller admission section of the outlet section of described water inlet flow channel and pump section, the outlet of the stator of pump section is connected with the import of the bend loss of outlet passage is smooth-going, straight smooth-going connection of import of expanding section of the outlet of the bend loss of outlet passage and outlet passage, described power plant lateral recumbent posture is arranged in a side of outlet passage, power plant and pump section, the bend loss of water inlet flow channel and outlet passage, the straight Duan Jun that expands is positioned at same plane.
Described pump section is axial-flow pump or stator mixed flow pump.
Described water inlet flow channel by the rectangular inlet section through asymmetric contraction smooth transition to the circular cross section that connects impeller inlet.
The bend loss of described outlet passage is made of a plurality of pipeline section smooth connections, and import is circular cross section, exports to be multi sphere line section, and the bend pipe section height is greater than the bend pipe section width, and import circular cross section smooth transition is to exporting multi sphere line section.
Described multi sphere line section is connected and composed by the camber line of multistage different curvature radius.
The straight expansion section of described outlet passage is made of a plurality of pipeline section smooth connections, and import is multi sphere line section, exports to be rectangular cross section, and import multi sphere line section smooth transition is to exporting rectangular cross section.
The bend loss of described outlet passage and straight each cross-sectional area longshore current road center line that expands section change undistorted, the smooth-going no flex point of both relation curves.
The utility model is rational in infrastructure, be optimized design by bend loss and the straight section that expands to water inlet flow channel and outlet passage, make the hydraulic loss of water inlet flow channel, outlet passage littler, further improve the purpose of pump-unit hydraulic efficiency, broken through the big technical bottleneck of bend loss hydraulic loss that traditional side direction S oblique crank Z is stretched tubular pump.
Motor and transmission device are positioned at the same plane of the same side of outlet passage, blade wheel chamber adopts the opposite opened structure, and need not when the dismounting water pump mobile motor can sling bend loss 3, makes things convenient for the installation maintenance of water pump, reduce the space of device maintenance such as pumping plant electromechanics, reduced construction investment.
Water-in and water-out runner center line and impeller, stator centerline collineation, base plate cope level and blade wheel chamber are close, and the pump house cutting depth need not to consider the length of water pump spindle, motor shaft only for the depth of immersion influence of impeller, reduce the whole height of pump house, saved construction investment.
The hydraulic efficiency height surpasses 82% through pump-unit physical experiments checking pump-unit peak efficiency, has surpassed the hydraulic efficiency that existing planar S oblique crank Z is stretched pump-unit.
The utility model is applicable to various axial-flow pump or the stator mixed flow pumping plant in farmland and fields such as regional drought resisting, urban flood defence water drainage and urban water supply, compares similar other pump-units, and it has safe and reliable, engineering cost is low, convenient for installation and maintenance, operating cost is few, efficient more and safety.
The construction of water inlet flow channel and outlet passage can select for use reinforced concrete soil scene formwork erection to build or adopt the steel plate processing and fabricating to be transported to on-the-spot the installation according to the scale of pumping plant.
