在差动旋喷泵上，依据测压管测压和数值计算结果，将旋转流场分为“外旋流”

On rotating jet pump differential according piezometric load and numerical results, the rotational flow field into "outer swirl" and "swirl within the" structure model were established. Proposed degree curves described effects of spin-shell effect tangential and radial velocity of the swirling flow, and hydraulic pressure loss, the hydraulic characteristics of the header. Reynolds number characteristics established between the rotational flow and swirling flow rate relationship moment.

On the differential rotary pump, according to the pressure tube pressure measurement and numerical calculation results, the rotating flow field is divided into "outer cyclone" and "inner cyclone" to establish its structural model. The effect of the degree of influence curve on the cutting and radial velocity, pressure and hydraulic loss of the swirling flow and the hydraulic characteristics of the catchment pipe is described by the influence of the vortex effect on the cyclone flow. Establish the characteristic Reynolds number and velocity moment relationship between the rotational flow and the swirl flow flow.

According to the results of pressure measurement and numerical calculation, the rotating flow field of differential jet pump is divided into "outer swirl" and "inner swirl", and its structure model is established respectively. The degree influence curve is proposed to describe the effect of the shell effect on the tangential and radial velocity, pressure and hydraulic loss of the swirling flow, and the hydraulic characteristics of the collecting pipe. The relationship between the characteristic Reynolds number and the velocity moment is established.
