例句与用法
- The method takes advantage of bezier curve to work out a set of blade profiles of centrifugal pump , using thickening law to thicken the profiles . then the pressure and suction lines of the blade can be obtained . it takes advantage of bezier surface to create pressure and suction surface and makes use of mdt software to create the three - dimensional blade entity
首先采用速度系数法计算得到离心泵叶轮的基本参数,再由b zier曲线生成一组叶轮叶片型线,按照加厚原理对型线进行加厚,得到正背叶片线,再采用张量积b zier曲面生成叶片正背面,由mdt进行三维实体造型得到叶片,从而得到流场计算区域的模型。 - 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
为确保灌注泵可靠工作,提出改进措施: ( 1 )采用改型环形泵体降低叶轮的径向力,减小轴封间隙,抑制泄漏; ( 2 )采用背叶片降低叶片根部压头,获得微压,使轴封两端承受较小压差; ( 3 )采用螺旋密封降低轴封两端压差,在保持微压的同时避免出现负压,密封效果更好; ( 4 )采用反压式填料密封结构,在很小的压紧力下,即可保证密封; ( 5 )采用具有润滑功效的柔性石墨填料,即使发生轴封泄漏,进入石墨内部的固相颗粒也将随着石墨的消耗而被钻井液吸收。
