( 3 ) the transformation for turbo cycling compressor is designed in both differential pressure seal parts at the inlet and outlet and the connecting construction of the positioning key and turbo cycling compressor casing : replace wave pipe of differential pressure seal parts with asbestos jointing and improve its reliability ; jointing connection of the positioning key and turbo cycling compressor casing has been converted into screw thread connection and avoid the dangers from jointing crack
（ 3 ）從進出口壓差密封部件和定位鍵與外殼間聯接結構兩方面入手，提出了相應的改造方案：將機組進出口壓差的密封部件由波紋管改為石棉填料函，提高了其運行可靠性；將內件周向定位鍵與外殼間的聯接結構由焊接改為螺紋聯接，避免了焊接裂紋引起的安全事故。 -

套管鄭興與密封加固工藝作法 -
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
為確保灌注泵可靠工作，提出改進措施： （ 1 ）採用改型環形泵體降低葉輪的徑向力，減小軸封間隙，抑制泄漏； （ 2 ）採用背葉片降低葉片根部壓頭，獲得微壓，使軸封兩端承受較小壓差； （ 3 ）採用螺旋密封降低軸封兩端壓差，在保持微壓的同時避免出現負壓，密封效果更好； （ 4 ）採用反壓式填料密封結構，在很小的壓緊力下，即可保證密封； （ 5 ）採用具有潤滑功效的柔性石墨填料，即使發生軸封泄漏，進入石墨內部的固相顆粒也將隨著石墨的消耗而被鉆井液吸收。 -
