Linear adjustment of the head of a spiral wound thick - wall pressure vessel
螺旋纏繞厚壁壓力容器封頭段的線型調整Water - fittings for house installation ; boltings with flat seal ; one side threaded coupling with inside - thread, on the other side steel tube nozzle, copper tube nozzle or sleeve pn 10
家裝設備用水管配件.平密封螺旋接頭.壓力10巴的一端Water - fittings for house installation ; boltings with flat seal ; one side threaded coupling with outside - thread, on the other side steel tube nozzle, copper tube nozzle or sleeve pn 10
家裝設備用水管配件.平密封螺旋接頭.壓力10巴的一端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。The crimped head design, prevents solids from dislodging the seal face, allows the seal to withstand higher pressure and rotational speed and eliminates the metal shell from contacting the seal ring
波紋式頭部設計，防止固體顆粒從密封面上撞出，使得密封能夠抵抗更高的壓力和旋轉速度，避免金屬殼接觸到密封環。分享友人
