Description
Technical field
The utility model relates to a kind of technical field of water pump, particularly a kind of technical field of through-flow pump.
Background technique
Through-flow pump is widely used in big flow, low lift pumping plant, because the restriction of the performance of pump own, flow～head curve is more precipitous.Although the full pumping plant of regulating of blade, can be according to the variation of flow and lift, by regulating the water pump blade laying angle, change pump performance, satisfy the operation needs of lift variation significantly, but often depart from the operation of efficient district, cause water pump efficiency low, can not give full play to the economic benefit and the social benefit of pump station engineering.For the tubular pump that adopts the frequency control of motor speed operation, not only can increase the equipment of pumping station investment greatly, the energy consumption of frequency conversion equipment can reduce pumping plant efficient, and more because lift changes pump assembly when making variable-speed operation, flow is directly proportional with the first power of rotating speed, and lift is directly proportional with the quadratic power of rotating speed, cause lift to reduce after, flow may not satisfy requirement.
Summary of the invention
The utility model provides a kind of exit guide vane adjustable through-flow pump, and in order to solve the tubular pump of frequency control of motor speed operation, frequency conversion causes lift to reduce, and flow does not satisfy the problem that requires.
The utility model comprises horn mouth, pump shaft, water pump vane, blade wheel chamber, exit guide vane, the exit guide vane body, the stator controlling mechanism, seal arrangement, described horn mouth is connected the front end of described blade wheel chamber, described exit guide vane body is connected the rear end of described blade wheel chamber, described water pump vane is arranged in the described blade wheel chamber, described water pump vane is connected on the described pump shaft, described exit guide vane is arranged in the described exit guide vane body, described exit guide vane is connected on the described pump shaft by bearing, it is external that described stator controlling mechanism is arranged on described exit guide vane by seal arrangement, the corresponding layout with exit guide vane of described stator controlling mechanism, the adjustable side of described stator controlling mechanism is fixedly connected on the described exit guide vane.
The utility model is according to the requirement of flow and lift, drive the exit guide vane rotation by the stator controlling mechanism, change the laying angle of exit guide vane, thereby reach the purpose that changes pump performance, but effectively enlarge the range of operation and the efficient district scope of water pump, particularly work with water pump blade through-flow pump impeller joint, the outlet and the exit guide vane inlet that guarantee impeller blade satisfy the design conditions requirement all the time, the operating mode that can satisfy lift to alter a great deal and require flow to remain unchanged substantially, and making water pump as far as possible in the operation of efficient district, this through-flow pump has compact structure, easy to adjust, stable advantage; When stator is in full closing state, can substitute the gate cutout of pumping plant outlet, reduce pumping plant stop gate quantity, reduce the pumping plant investment.
