泵軸從入口向出口轉為正轉，反之為反轉。2,站在電機風罩端面，如風向電機里抽為正轉，風往外排則為反轉。3,在機泵的殼上一般都標有轉向的紅色箭頭，如轉向與箭頭指向一致為正轉，否則為反轉.4,看立式管道泵葉輪的轉向切線方向是沖著出口的就是正轉.立式管道泵工作時是平衡的。葉輪直接安裝在電機的加長軸上，軸向尺寸短，結構緊湊，泵與電機軸承配置合理，能有效地平衡泵運轉產生的徑向和軸向負荷，從而保證了泵的運行平穩，震動噪音低。進出口口徑相同，且位于同一中心線上，可像閥門一樣安裝于管路之中，設有安裝底腳，增加泵的穩定性，外形緊湊美觀，占地面積小，建筑投入低。這里所說的管道泵溢流閥，實際上就是安全閥。通過調整安全閥（溢流閥）的開啟壓力。

In order to make its sewage self-priming pump suction pipe will not appear the phenomenon of gas accumulation, sewage self-suction pump suction pipe requirements of the fewer elbow the better, up to one elbow is appropriate, suction water to the pump import should be arranged in the way of slope upward to avoid the phenomenon of accumulation of gas. In order to ensure that the sewage self-suction pump suction pipe completely sealed non-leaking phenomenon of sewage self-priming pump suction pipe should not be increased and reduced. Sewage self-suction pump suction pipe Increased after the pipeline will have a large number of gas is not easy to clean, sewage self-suction pump self-suction exhaust time after the pump body inside the water will change heat pump body hot, will lead to sewage self-suction pump can not absorb liquid, sewage self-suction pump suction pipe shrinkage, Because the export is larger than the import and the discharge of large flow of traffic caused by the import flow can not keep up with the export flow, so there will be a failure. Sewage self-priming pump suction pipeline requirements of quality and material requirements are very strict. Therefore, water suction pipes usually use steel tubes or PVC tubes.

三、管道泵工作條件:
1、吸入壓力≤1． 0MPa，或泵系統工作壓力≤1．6MPa，即泵吸入口壓力+泵揚程≤1．6MPa，泵靜壓試驗壓力為2．5MPa，訂貨時請注明系統工作壓力。泵系統工作壓力大于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接部分采用鑄鋼材料。 
2、環境溫度<40℃，相對濕度<95％。
3、所輸送介質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、管道泵產品特點:

1、管道泵為立式結構，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，結構緊湊，泵與電機軸承配置合理，能有效地平衡泵運轉產生的徑向和軸向負荷，從而保證了泵的運行平穩，振動小、噪音低。

So repeated cycle, gradually the pipe in the air drained, so that water into the pump, complete the self-suction process. Sewage pump sewage self-suction pump oil pump diaphragm pump screw pump gear oil pump internal mixed sewage self-suction pump. More water is needed to fill the entire pipe before starting. Bottom valves are often faulty due to inclusions or lax closure of themselves, and eliminating these failures can sometimes take a lot of labor, especially in winter. There are many structural types of sewage self-priming pump, among which, on the other hand, the water discharged into the gas-water separation chamber by the impeller is returned to the outer edge of the impeller by the left and right backwater flows. The left backwater hole flows back to the water under the action of pressure difference and gravity, shot into the impeller groove, and was crushed by the impeller, mixed with the air from the pipeline, dumped into the worm shell, vacuum pump liquid pump metering pump gear pump corrosion pump resistance pumps fire pump to the direction of rotation flow. Ordinary centrifugal pump at the bottom of the pipeline with the bottom valve and then the right backwater hole flow to the water confluence working principle and the external mixed sewage self-suction pump is the same.

今年前7個月，江北還重點打造三大智能產業平臺，為都市工業發展集聚動能。當天會議上，家居五金第二批團體家居五金移門滑輪、家居五金偏心連接件通用技術要求制定啟動儀式同步舉行，這項技術將會在模具領域不斷推廣應用(也是模具智能化實現的重要途徑)。B端電商不同于C端，除了用戶，更講究用戶黏性。15日的報告廳，花團錦簇，融洽。
