Abstract
The utility model discloses a first stage separate type double-suction impeller for multi-stage centrifugal pumps, which is composed of a first stage impeller, a flow guiding body, and a secondary impeller, wherein, the first stage impeller adopts a homolateral double-suction separate distributing structure. The utility model has the characteristics of small volume, compact structure, and convenient installation and maintenance. Simultaneously, the utility model has low air corrosion residual quantity and efficiency. The utility model can be widely used in suction stages of multi-stage centrifugal pumps.
Description
The utility model relates to a kind of centrifugal pump impeller, particularly a kind of multistage centrifugal pump impeller.
Existing multistage centrifugal pump sucks the level blade wheel structure and comprises first stage impeller and secondary impeller.Wherein first stage impeller adopts the both sides double suction, liquid mobile is two suction ports that the liquid of Pump Suction Nozzle flows into double-entry impeller respectively, import secondary impeller through double-entry impeller and deflector, finish the function that sucks and increase liquid energy, the shortcoming of this structure is that structural volume is big, design arrangement is difficult, the assembly and disassembly difficulty, is not convenient for maintenance.
The purpose of this utility model is to provide that a kind of volume is little, compact structure, easy to maintenance, multistage centrifugal pump first stage separate impeller with low net positive suction head.
The purpose of this utility model is achieved through the following technical solutions:
Impeller unit is made up of one-level impeller, deflector, sencond stage impeller, and said one-level impeller is made up of two single suction impellers, and two single suction impellers are according to sucking the direction apart arrangement together.
The utility model has adopted two single suction impeller equidirectional layouts, have that volume is little, compact structure, cost are low, characteristics, installing/dismounting and maintenance are all very convenient.This blade wheel structure is installed is had low net positive suction head and efficient, can be widely used in the suction level of multistage centrifugal pump.
Fig. 1 structural representation of the present utility model.
Below in conjunction with accompanying drawing the utility model is described in further detail.
The flow of fluid of multistage centrifugal pump is that the liquid of Pump Suction Nozzle 1 imports 2,4, two single suction impeller 2,4 equidirectional apart arrangement of two single suction impellers respectively, and it is identical sucking direction.The flow that passes through of each impeller is 50% of a pump total discharge, and the liquid of first impeller 2 and second impeller 4 outflow imports secondary impeller 5 by deflector 3, finishes the double suction effect, and the liquid of finishing requirement sucks and increase the function of energy.
