This will also lead to sewage self-suction pump can not absorb water phenomenon. If the sewage self-priming pump suction pipe to have a pipe into 2 pipes, we should pay special attention to the loss of 2 pipes is relatively large, should be based on the maximum flow rate of the pipeline to choose the corresponding sewage self-suction pump suction pipe, from the understanding of the company can consult the relevant experts, We will calculate the corresponding pipe size for you according to the flow rate of the relevant sewage self-priming pump you need, so as not to avoid the flow of sewage self-priming pump to meet the design standards, to prevent unnecessary trouble. Sewage self-suction pump suction pipe requirements and sewage self-suction pump suction pipe can not be inserted into the pool depth is too shallow. Self-suction refers to the pipe in the tube without filling the liquid (but the pump body must have enough liquid) to start the pump, the pump itself can automatically remove the gas in the tube, and then into normal operation, the pump in the initial start must be filled with enough liquid, after the start of the liquid retained in the pump to ensure that the pump can start again. The self-priming time of the sewage self-priming pump refers to the pump cleaning liquid at room temperature, the installation height for the allowable vacuum () minus 0.5, from the pump start to the pressure stability of the shortest time required, that is, the pump drain despite the internal air required time. For centrifugal sewage self-priming pump, the pipe length between the suction surface and the pump inlet (Tube hole diameter).

但一般試壓泵與管網(wǎng)連接處要安裝一個(gè)閥門或者止回閥，防止管網(wǎng)介質(zhì)回流，并且試壓泵上壓力表的壓力也容易受試壓泵活塞工作而容易產(chǎn)生波動(dòng)。所以一般將管網(wǎng)壓力升至試驗(yàn)壓力后，關(guān)閉試壓泵與被測(cè)管網(wǎng)之間的閥門，來觀察被測(cè)管網(wǎng)有無滲及管網(wǎng)上壓力表壓力值下降范圍是否符合規(guī)范要求；壓力試驗(yàn)是否合格，要以被測(cè)管網(wǎng)上的壓力表讀數(shù)下降范圍為準(zhǔn)。當(dāng)葉輪旋轉(zhuǎn)時(shí)，由于葉輪內(nèi)運(yùn)動(dòng)液體的離心力Fu大于在流道內(nèi)運(yùn)動(dòng)液體的離心力只，兩者之間產(chǎn)生一個(gè)旋渦運(yùn)動(dòng)，其旋轉(zhuǎn)中線是沿流道縱向，稱為縱向旋渦，在縱向旋渦作用下，液體從吸人至排出的整個(gè)過程中，可以多次進(jìn)人與流出葉輪，類似于液體在多級(jí)離心泵內(nèi)的流動(dòng)狀況。液體每流經(jīng)葉輪一次，就獲得一次能量。當(dāng)液體從葉輪流至流道對(duì)，就與流道中運(yùn)動(dòng)的液體相混合。由于兩股液流速度不同，在混合過程中產(chǎn)生動(dòng)量交換。流體由吸人口進(jìn)道和葉輪使流道中液體的能量得以增加。管道旋渦泵主要是依靠這種縱向旋渦傳遞能量。
