滑石的最小及最佳納米粒子的結構表徵與計算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。It was showed that the dlc gradient film has a smooth surface with noncrystal amorphous structure, its surface vicker ' s hardness was as about three times as that of ti6a14v alloy substrate, and high adhension strength of no less than o. sgpa between dlc film and substrate was estimated by liquid quench method
