Abstract
The utility model discloses a kind of first stage impeller double-sucking type radial subdivision two end supports multistage centrifugal pump; This multistage centrifugal pump is primarily of the pump housing, pump shaft, impeller, stator composition; It is characterized in that the first stage impeller of described impeller adopts double-entry impeller, double suction suction chamber is loop configuration, and stator is contained in the double-entry impeller outer rim in annular pumping chamber, and transition runner is located to export on the pump cover on the left of first order impeller and with stator and connects.Because first stage impeller have employed double-entry impeller, and with the respective outer side edges of transition runner and double suction suction chamber, thus increase the flow of pump, improve the cavitation performance of first stage impeller entrance and double suction suction chamber, balance the pressure of Pump Suction Nozzle, widened the application of this type pump, meet the use occasion of large discharge, also improve hydraulic efficiency simultaneously, extend working life.
Description
One, technical field
The utility model relates to mechanical engineering pump class technical field, specifically a kind of first stage impeller double-sucking type radial subdivision two end supports multistage centrifugal pump.
Two, background technique
At present, China's radial subdivision two end supports multistage centrifugal pump first stage impeller many employings single suction structure, its structure is simple, and casting difficulty is little, but flow is less, and should not be used for the occasion of large discharge, cavitation performance is poor, and working life is short.
Three, summary of the invention
In order to overcome the deficiencies in the prior art, the purpose of this utility model provides a kind of first stage impeller double-sucking type radial subdivision two end supports multistage centrifugal pump of augmented flow.
The technological scheme realizing the purpose of this utility model employing is: this multistage centrifugal pump is primarily of the pump housing, pump shaft, impeller, stator composition; It is characterized in that the first stage impeller of described impeller adopts double-entry impeller, double suction suction chamber is loop configuration, and stator is contained in the double-entry impeller outer rim in annular pumping chamber, and transition runner is located to export on the pump cover on the left of first order impeller and with stator and connects.
The beneficial effects of the utility model are: because first stage impeller have employed double-entry impeller, and with the respective outer side edges of transition runner and double suction suction chamber, thus increase the flow of pump, improve the cavitation performance of first stage impeller entrance and double suction suction chamber, balance the pressure of Pump Suction Nozzle, widened the application of this type pump, meet the use occasion of large discharge, also improve hydraulic efficiency simultaneously, extend working life.
Four, accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is the structural representation of the utility model first stage impeller double-sucking type radial subdivision two end supports multistage centrifugal pump.
In figure: 1. double suction suction chamber, 2. double-entry impeller, 3. transition runner, 4. stator.
Five, embodiment
In the accompanying drawings, the utility model first stage impeller double-sucking type radial subdivision two end supports multistage centrifugal pump, this multistage centrifugal pump is primarily of the pump housing, pump shaft, impeller, stator composition; It is characterized in that the first stage impeller of described impeller adopts double-entry impeller 2, double suction suction chamber 1 is loop configuration, and stator 4 is contained in double-entry impeller 2 outer rim in annular water absorbing chamber, and transition runner 3 is located to export on the pump cover on the left of first order impeller and with stator 4 and connects.Liquid enters transition runner by the guide functions through stator after impeller, and transition runner has diffusion recovered energy and accelerates the effect that liquid enters subordinate's impeller, ensure that the high efficiency of complete machine.
