气体进入叶轮后，叶轮的做功能力减弱，气体与泵内的水开始进行气液混合，叶轮外缘出现了明显的气液混合带，如图4.4（c）的黄色区域所示。自此，泵内开始了气液混合与气液分离。气液混合后，少部分气液混合物从进口排出，另一部分进入气液分离室，气体上浮，液体下沉，经回流孔流回叶轮。图4.4（b）、4.4（c）、4.4（d）中回流孔附近气体体积分数接近为0，则表明液体经由回流孔的回流现象。随着叶轮的转动，协同气体和少量气液混合物的溢出，在泵进口处形成了负压，进水管内的气体都被吸入叶轮，液体也开始进入叶轮。一开始气液混合物大多附着于叶片上，后从蜗壳大断面侧扩散开来，与进气时的分布相反，且含水量越来越高，如图4.4（e）和4.4（f）所示。随着大量液体经S型弯管涌进叶轮，叶轮处含气率飞快降低，水迅速灌入叶轮，泵进入自吸突变阶段。此阶段叶轮做功能力较强，泵内气体大多积聚于气液分离室中，叶轮处含气率接近于0，如图4.4（h）所示。此时泵内的水一部分直接排出，流量激增至稳定，另一部分经扩散段灌入气液分离室，侵占气液分离室的空间，气液分离室内的气体逐渐从出口被逼出，至此，自吸完成。영어
When the gas enters the impeller, the working force of the impeller decreases, and the gas and water in the pump begin to mix. The obvious gas-liquid mixing zone appears on the outer edge of the impeller, as shown in the yellow area of Figure 4.4 (c). Since then, gas-liquid mixing and gas-liquid separation have begun in the pump. After gas-liquid mixing, a small part of the gas-liquid mixture is discharged from the inlet, and the other part enters the gas-liquid separation chamber. The gas floats and the liquid sinks, and flows back to the impeller through the reflux orifice. In figs. 4.4 (b), 4.4 (c), 4.4 (d), the volume fraction of gas near the reflux orifice is close to 0, which indicates the reflux phenomenon of liquid through the reflux orifice. As the impeller rotates, a negative pressure is formed at the inlet of the pump due to the overflow of synergistic gas and a small amount of gas-liquid mixture. The gas in the intake pipe is sucked into the impeller, and the liquid begins to enter the impeller. At first, the gas-liquid mixture mostly adheres to the blade, and then diffuses from the large section side of the volute, which is contrary to the distribution of the intake air, and the water content is getting higher and higher, as shown in figs. 4.4 (e) and 4.4 (f). With a large number of liquids pouring into the impeller through S-shaped elbow, the void fraction at the impeller decreases rapidly, and water is rapidly poured into the impeller, and the pump enters the self-priming mutation stage. In this stage, the impeller has strong function, and most of the gas in the pump accumulates in the gas-liquid separation chamber. The air content in the impeller is close to 0, as shown in Fig. 4 (h). At this time, part of the water in the pump is discharged directly, and the flow rate increases sharply to a stable level. The other part is injected into the gas-liquid separation chamber through the diffusion section, which occupies the space of the gas-liquid separation chamber. The gas in the gas-liquid separation chamber is gradually forced out from the outlet and self-priming is completed.
