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).

三、管道泵工作條件:
1、吸入壓力≤1． 0MPa，或泵系統(tǒng)工作壓力≤1．6MPa，即泵吸入口壓力+泵揚程≤1．6MPa，泵靜壓試驗壓力為2．5MPa，訂貨時請注明系統(tǒng)工作壓力。泵系統(tǒng)工作壓力大于1．6MPa時應在訂貨時另行提出，以便在制造時泵的過流部分和聯(lián)接部分采用鑄鋼材料。 
2、環(huán)境溫度<40℃，相對濕度<95％。
3、所輸送介質(zhì)中固體顆粒體積含量不超過單位體積的0．1％，粒度<0．2mm。

注：如使用介質(zhì)為帶有細小顆粒，請在訂貨時說明，以便廠家采用耐磨式機械密封。

四、管道泵產(chǎn)品特點:

1、管道泵為立式結(jié)構(gòu)，進出口口徑相同，且位于同一中心線上，可象閥門一樣安裝于管路之中，外形緊湊美觀，占地面積小，建筑投入低，如加上防護罩則可置于戶外使用。
2、葉輪直接安裝在電機的加長軸上，軸向尺寸短，結(jié)構(gòu)緊湊，泵與電機軸承配置合理，能有效地平衡泵運轉(zhuǎn)產(chǎn)生的徑向和軸向負荷，從而保證了泵的運行平穩(wěn)，振動小、噪音低。

泵軸支撐，解決了原來立式泵靠電機軸承支撐的不足之處；采用水力模型的葉輪，消除了原立式泵軸向力大的不足之處；電機采用Y系列標準通用電機，解決原立式泵加長軸電機配套更換難的問題；同時100％的便拆結(jié)構(gòu)，解決了更換大功率水泵的軸承，機械密封，葉輪，便拆立式管道泵與國內(nèi)同類產(chǎn)品相比，具有運轉(zhuǎn)更平穩(wěn)，使用壽命長，配套更方便，維護保養(yǎng)更輕松等等，無可代替的優(yōu)點。在立式泵系列產(chǎn)品中屬國內(nèi)前列，各項技術(shù)居國內(nèi)，是替代ISG型立式泵，IS型離心泵，S型雙吸泵等常規(guī)各種離心泵的產(chǎn)品�？戳⑹焦艿辣秒姍C頂部風扇的轉(zhuǎn)向是否符合泵體紅色箭頭指向的方向,轉(zhuǎn)速太快看不出來的話,在剛停泵時看風扇慣性的轉(zhuǎn)向。1,試泵時站在泵的端面。

據(jù)統(tǒng)計，采用虛擬現(xiàn)實設計的波音777飛機，設計錯誤修改量了90%、研發(fā)周期縮短了50%、成本了60%，核心觀點：1、貿(mào)易企業(yè)由于執(zhí)行鋼廠協(xié)議被動選擇備貨占比較大，備貨庫存多數(shù)控制在月銷量30%以內(nèi)。誠如李樹斌所說的，要想改變這個狀況絕非朝夕之功。產(chǎn)品本身是做性價比的，因此利潤空間不大，肯定要漲價，另外按照目前同檔次的價格水平我們上漲10%仍然具有很強的價格競爭優(yōu)勢，城市建設更加恢宏，城市文明也在快速進步。
