为了更清楚地观察进水管中的气体与液体进入叶轮的自吸过程，取YZ轴截面的气液两相分布云图，如图4.5所示。
图4.5（a）到图4.5（d）清晰地显示了自吸泵进气阶段，部分液体的排出及气液分离室内液面的下降；图4.5（e）显示了进水管内液体由于负压的作用，涌向泵S型弯管的过程，以及少量气液混合物从回流孔进入气液分离室，再参加循环的过程；图4.5（f）到图4.5（j）则显示了大量液体进入泵体后，出口流量激增的自吸突变阶段，以及气液分离室内涌入液体逼迫气体经由出口排出的自吸末期剩余气体排放过程。
由图4.5可见，经总结，自吸过程可大致分为进气阶段（0-20s）、进水排气阶段（20-24s）和剩余气体排放、正常输水阶段（24-40s）。

In order to observe more clearly the self-suction process of gas and liquid entering the impeller in the intake pipe, the gas-liquid two-phase distribution nephogram of the cross section of YZ axis is taken as shown in Fig. 4.5.
Figures 4.5 (a) to 4.5 (d) clearly show the intake stage of the self-priming pump, the discharge of some liquids and the drop of the liquid level in the gas-liquid separation chamber; Figure 4.5 (e) shows the process of the liquid in the intake pipe flowing into the S-shaped elbow of the pump due to the negative pressure, and a small amount of gas-liquid mixture entering the gas-liquid separation chamber from the reflux orifice and then participating. Cycle process; Fig. 4.5 (f) to Fig. 4.5 (j) show the self-suction catastrophe stage of the sudden increase of outlet flow rate after a large number of liquids enter the pump body, and the process of residual gas emission at the end of self-suction period when liquid forced gas enters the gas-liquid separation chamber through the outlet.
From Figure 4.5, it can be seen that the self-priming process can be roughly divided into intake stage (0-20s), intake and exhaust stage (20-24s), residual gas emission and normal water delivery stage (24-40s).
