The pipelines arrangement of type S pump looks simple and beautiful due to inlet and outlet at a same center line. The same rotor of type S pumps can be operated at reverse direction to avoid damage to the pumps by water hammer. Unique design of type S pumps working at high temperature using middle support to fasten the pump casing and using cooling seals oil lubrication bearing then pump suitable for working at 200 especially for suppling heated water to pipe net system.5. Type S pump casting parts can be vertically or horizontally mounted acoording to different working condition, with mechanical seals or packing seals.6. Type S pumps look beautiful with visible lines adopting industrially designing.COST ADVANTAGE:1. The efficiency of S pumps are 2%3% higher than the same type pumps due to adopting advanced hydraulic model and thus minimum the operating costs.2. The NPSH of type S pumps are 1-3 meters lower than the same type split pumps due to using advanced hydraulic model and advanced manufacturing technique and thus minimize the foundation costs and extendling the using life.3. Type S pumps are suitable for any site working condition due to using SKF NSK bearing and other parts chosen by the customers and thus minimize the maintenance costs.可能发生的故障及其他解决办法(Possible failures and other solutions)故障(Fault)原因(Reason)解决办法(Solution)1、泵不吸水、压力表和真空表指针剧烈跳动。(the pump does not absorb water, pressure gauge and vacuum gauge pointer jumping.)灌注水不够。管路与仪表联接处漏气。(Perfusion was not enough water. Piping and instrument connection at the leak.)检查底阀是否漏水，再灌足引水拧紧漏气处。(Check the bottom valve is leaking, then primed with a diversion tighten the leak.)2、水泵不吸水，真空表表示高度真空。(the pump does not absorb water, vacuum gauge indicates high vacuum.)底阀没有打开或已堵塞，吸水管路阻力太大。吸水高度过高。(End of the valve does not open or blocked suction line too much resistance. Suction height is too high.)检查底阀，更换吸水管，降低吸水高度。(Check the bottom valve, replace the suction pipe, reduce the suction height.)3、压力表有压力，但仍不出水。(the pressure gauge pressure, but still water.)出水管阻力太大。旋转方向不对。叶轮堵塞，泵转速不快。(Outlet pipe too much resistance. Rotating in the wrong direction. Slow speed pump impeller blockage)检查或缩小短水管、检查电同。清理叶轮、增加泵转速。(Check in or out of short pipes, check the power. Clean the impeller to increase the pump speed.)4、流量低于设计要求。(the flow is lower than the design requirements.)水泵堵塞、密封环磨损过多，转速不足。(Clogging pump, the seal ring wear is excessive, insufficient speed.)清理水泵及管路，更换密封环增加转速。(Clean water pump and piping, replace the seal ring to increase speed.)5、泵消耗功率过大。(the pump power consumption is too large.)填料压行太紧，并发热、叶轮有磨损、泵流量增大。(Packing pressure line is too tight, and fever, impeller wear, pump flow rate increases.)告诉填料压盖，检查泵轴是否弯曲、更换叶轮、增加出水阻力。降低流量。(Tell gland, check the pump shaft is bent, replace the impeller to increase water resistance. Reduce traffic.)6、泵内声音反常，泵不出水。(pump sound unusual, pump no water.)吸水管阻力过大，在吸水处有空气渗入，输送的液体温度过高。(Suction pipe is too much resistance, air infiltration, soaked in water at the temperature of the transmission fluid.)检修及水管，检查底阀，减少吸水高度，填塞漏气处，降低温度。(Maintenance and plumbing, check the bottom valve, reducing the suction height, packing leak at lower
