环形泵 meaning in English
ring-section pump
Examples
- It can be used for a transporting many kinds of liquids and gases and it is available in a wide range of sizes and discharge capacities
可用于气体和液体输送等各种用途。我们有不同吞吐量和大小的环形泵，欢迎选用！ - The ring pump has a structure that employs an eccentric ring movement to pump liquids while minimizing damage to the tube through which they pass
增加管道的使用寿命我公司生产的环形泵是一种通过径向力有效减少管道磨损的产品。 - This kind of tube pump is ideal for pumping solutions that need to remain free from mixing and contamination because they operate without touching anything bur the outside surface of the tube
输送的液体只接触管道，因此不会产生卫生安全问题，更不必担心杂质混入液体，环形泵是您的最佳选择。 - To ensure the charging pump working reliably , the following measures should be adopted : ( 1 ) adopting modified circular casing to reduce the radial force of the impeller and decrease the seal clearance ; ( 2 ) using radical ribs on impeller and helical sealing on shaft to realize minor pressure differential ; ( 3 ) using back pressure stuffing box to ensure sealing under small packing force ; ( 4 ) adopting self - lubricant flexible graphite stuffing for absorption of solids entering in the graphite in case of leaking
为确保灌注泵可靠工作，提出改进措施： ( 1 )采用改型环形泵体降低叶轮的径向力，减小轴封间隙，抑制泄漏； ( 2 )采用背叶片降低叶片根部压头，获得微压，使轴封两端承受较小压差； ( 3 )采用螺旋密封降低轴封两端压差，在保持微压的同时避免出现负压，密封效果更好； ( 4 )采用反压式填料密封结构，在很小的压紧力下，即可保证密封； ( 5 )采用具有润滑功效的柔性石墨填料，即使发生轴封泄漏，进入石墨内部的固相颗粒也将随着石墨的消耗而被钻井液吸收。
