'4.6.2 自吸过程,图4.4所示为模型一自吸泵自吸过程中，叶轮截面关键时间点的气液两相分布云图。其中图4.4（a）到图4.4（c）为自吸前期启动阶段，图4.4（d）到图4.4（f）为自吸中期稳定阶段，图4.4（g）到图4.4（i）为自吸后期突变阶段，自吸时间t=16s后为自吸末期正常输水阶段，同时少量剩余气体缓慢排出。,结合自吸泵的初始阶段状态图4.3分析，未启动时，上半段红色区域，气体体积分数为1，下半段蓝色区域，气体体积分数为0，交界面与进水管最低处齐平，交界面气体体积分数介于0-1之间。自吸泵启动后，转速迅速从0增至1800r/min，在叶轮的旋转作用下，泵内储存的水迅速流向出口段，进水管中的气体也迅速进入叶轮，叶轮含气率逐渐增大，且气相从蜗壳小断面一侧的叶轮背面开始，由叶轮进口，沿着叶轮半径方向逐渐扩散，与此同时，泵内一部分储存水携带少许气液混合物先由出口段排出，如图4.4（a）和4.4（b）所示，另一部分水呈抛射状进入气液分离室，此抛射现象在图4.4（a）中最明显。'

4.6.2 Self-priming Process,Figure 4.4 shows the gas-liquid two-phase distribution cloud at the critical time point of impeller cross-section during the self-priming process of model-self-priming pump. Fig. 4.4 (a) to f I g. 4.4 (c) is the initial stage of self-priming, Fig. 4.4 (d) to Fig. 4.4 (f) is the stable stage of self-priming, Fig. 4.4 (g) to Fig. 4.4 (i) is the sudden change stage of self-priming, and after self-priming time t = 16 s, it is the normal water-conveying stage of self-priming, while a small amount of residual gas is discharged slowly.,According to the analysis of the initial stage state of the self-priming pump shown in Figure 4.3, when the pump is not started, the volume fraction of the gas in the red region of the first half is 1, the volume fraction of the gas in the blue region of the second half is 0, and the interface is level with the lowest part of the intake pipe, and the volume fraction of the gas in the interface is between 0 and 1. After the start-up of the self-priming pump, the speed increases rapidly from 0 to 1800 r/min. Under the rotating action of the impeller, the water stored in the pump flows rapidly to the outlet section, and the gas in the intake pipe enters the impeller rapidly. The air content of the impeller increases gradually, and the gas phase starts from the back of the impeller on the small section side of the volute, from the inlet of the impeller, along the radius of the impeller. At the same time, part of the stored water in the pump carries a little gas-liquid mixture out of the outlet section. As shown in figs. 4.4 (a) and 4.4 (b), the other part of the water enters the gas-liquid separation chamber in a projectile form. This projection phenomenon is most obvious in Fig. 4 (a).。
'即在y<0.095m且z>-0.3m区域内，设置为液相，除液相以外区域设置为气相，进口边界条件设为液相。同时，根据实际测得的启动时的转速变化规律，用CEL语言编译其简化了的函数，将转速设置成随时间先增大后稳定为1800r/min的函数。转速的CEL语言程序如下：'

That is, in the Y & lt; 0.095m and Z & gt; - 0.3m region, the liquid phase is set, the gas phase is set in the region except the liquid phase, and the inlet boundary condition is set as the liquid phase. At the same time, according to the actual measured change law of starting speed, the simplified function is compiled with CEL language, and the speed is set to increase with time and then stabilize to 1800 r/min. The CEL program of speed is as follows:。
'CFX软件中的应用语言为CEL语言，使用CEL语言进行初始状态设置。自吸泵第一次启动前需注水至水面与进水管齐平，后每次启动由于泵体储水作用，均无需再次注水，故称为自吸泵。根据自吸泵的尺寸参数及气液两相初始分布状态，编辑了如下CEL语言程序：'

The application language of CFX software is CEL language, which is used to set the initial state. The self-priming pump needs to be injected to the water surface and the intake pipe level before the first start-up. Since the water storage function of the pump body does not need to be injected again, it is called the self-priming pump. According to the size parameters of the self-priming pump and the initial distribution of gas and liquid phases, the following CEL program is edited:。
