结构特点:

1. 水泵两端支承间距短,泵运行稳定,振动噪声小,并可适当升速运行,使水泵适应范围更广。

2. 进出水口在同一直线上,使管线布置简单方便、美观。

3. 同一转子可反向运行,降低了水锤引起水泵损坏的风险。

4. 独特的高温型设计,水泵采用中间支撑、加厚泵体、密封冷却、轴承稀油润滑等,使水泵可应用于高达200℃的运行场合,特别适用于供热管网使用要求。

5. 泵体部分可根据使用条件的变化采取立式或卧式安装,密封可采用机械密封或填料密封。

6. 水泵外型应用工业化设计,线条清晰,符合现代审美观。

7. 选(采)用优异的水力模型,使泵的效率比同类型泵高2-3%,大大降低了泵的运行成本。

8. 必需汽蚀余量降低1-3米,从而降低土建投资,延长了使用寿命。

9. 选用进口轴承,零件材料可根据用户应用要求选用,使泵能适应各种现场运行条件,大大降低了维修成本。

10. 无调整式机械密封,更换机械密封成为轻松简单的工作。

11. 应用弹性预应力设计装配,转子部件装拆简单迅速。

12. 装配时无须调整各种间隙。

Structure Feature:

⒈Type XS pumps work stably with less noise and vibration, may be properly work at

raising speed due to short spacing between both side supports, thus they can be widely used.

⒉The pipelines arrangement of type XS pump looks simple and beautiful due to inlet and outlet at the same line.

⒊The same rotor of type XS pumps can be operated in reverse direction to avoid damage to the pumps by water hammer.

⒋Unique design of high temperatare form: using middle support, thickening the pump

casing, using cooling seals and oil lubrication bearing, make XS pump suitable for working at 200℃, especially for suppling heating net system.

5. Type XS pump can be vertically or horizontally mounted acoording to different working

condition, with mechanical seals or packing seals.

6. With industrial design, the outline of XS is clear and beatitiful in line with modern

aesthetics.

7. The efficiency of XS pumps are 2%~3% higher than the same type pumps due to adopting

advanced hydraulic model and thus reduce the operating costs significantly.

8. The NPSHr of type XS pumps are 1-3 meters lower than the same type split pumps which

reduced the foundation costs and extend the using life.

9. Choosing import brand bearing, and other parts material chosen by customer, make the pump suitable for any operation condition and reduce the maintenance cost significantly.

10. It is not necessary to adjust mechanical seals, so it is very easy and simple to replace

them.

11. It is rapid and simple to assemble and dismount the rotor parts due to using elastic

prestress assembling.

12. It is unnecessary to make adjustment to any clearance when assembling
