針對這種情況,大港油田新世紀機械製造有限公司研製成功一種新型無油管採油裝置,這種裝置以空心抽油桿代替實心抽油桿帶泵工作併兼作出油流道,還通過一種新型懸掛器將整筒抽油泵固定在套管壁上,提高了抽油泵的工作穩定性。 -
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。
