本文的研究表明,在偉l ]約鉆頭壽命的軸承密封潤滑系統中,採用端面一徑向組合密封結構能夠在一定程度上適應牙輪鉆頭轉速提高的發展趨To enhance the reliability of bearing seal of cone bit, this paper plans to adopt face - radial combination sealing structures ; that is to say, end - face and radial seal are arranged in one bit simultaneously. the nonlinear finite element method is applied to analyze and optimize the design of sealing structures
為了提高牙輪鉆頭軸承密封的可靠性,本文設計採用端面-徑向組合密封結構,即在一隻鉆頭中同時布置端面和徑向密封,採用非線性有限元方法對密封結構進行分析和優化。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。When installing the mixer, you should miunimize diameter at shaft gland towards quaking magnitude. the mixer mustn ' s be counterclocked, otherwise it will drop
安裝攪拌器要求軸封處之徑向跳動量調到最小程度,攪拌器不可反轉,以免脫落。Rotary shaft lip type seals for automobils ; test ; radial force measuring instrument digital
汽車用唇型旋轉軸密封件.第9部分:試驗.數字式徑向力The paper deduced the seal torque of the tri - eccentric butterfly valve and gave it a qualitative analysis. the results indicated : for the tri - eccentric butterfly valve with the same caliber, theseal torque would decrease with the butterfly disc thickness increasing ; the seal torque would increase with the radial eccentricity increasing ; however, the axis eccentricity effected on the seal torque minutely ; the seal torque would increase with the half cone angle increasing appreciably of the cone which the butterfly disc belonged to
本文還對三偏心蝶閥的密封力矩作了推導並進行了定性的分析,結果表明,對于同一口徑的三偏心蝶閥,密封力矩與蝶板的厚度近似成反比;與徑向偏心距近似成正比,變化也很明顯;而軸向偏心距對密封力矩的影響不是很大;密封力矩隨著蝶板所在的圓錐半錐角的增大而有所增加。Thermoplastics piping systems. end - load bearing joints between small diameter pressure pipes and fittings. test method for leaktightness under internal water pressure, including end thrust
