| 1. | The method of energy consumption test and calculation for crude oil pipeline transport system 原油长输管道系统能耗测试和计算方法 |
| 2. | Highway transport formed with the appearance of gas engine , followed by airline and pipeline transport 综合运输是经济活动的基础,是经济发展的“先行官” 。 |
| 3. | Two - phase flow widely exists in processes such as power , chemical , petrol , metallurgy , pipeline transport , medical and refrigeration industries 两相流广泛存在于动力、化工、石油、冶金、管道运输、医药、制冷等领域。 |
| 4. | There are five basic modes of transportation . they are water transport , rail transport , truck transport , air transport and pipeline transport 基本运输方式有五种,他们是水陆运输、铁路运输、汽车运输、航空运输和管道运输。 |
| 5. | The extensive research on gas hydrate started at the moment when people were encountered the problem of plugging , which was resulted from gas hydrate in the pipeline transport of natural gas 摘要人们对气体水合物的实质性研究始于对天然气管道运输中遇到的天然气水合物堵塞问题。 |
| 6. | In long distance slurry pipeline transport project , it often need to calculate friction loss of settling slurry in inclined pipeline , but up to now , the research about this aspect is not much 长距离浆体管道输送工程中,常常要涉及到倾斜管道浆体输送的摩阻损失问题,而对于这方面的研究到目前为止,并不是很多。 |
| 7. | Along with rapid development of china petroleum and natural gas industries , especially with speeding up globe economic integration , the reform of china oil and gas pipeline transporting prices must be enforced 随着我国石油天然气工业的迅猛发展,尤其随着全球经济一体化进程的加快,我国油气管输价格改革势在必行。 |
| 8. | Therefore , determination of reasonable oil and gas pipeline transporting price is not just related to the enterprises " own benefits but also has a great effect on oil and gas production enterprises and downstream customers 因此,研究制定合理的油气管输价格,不仅关系到管输企业的切身利益,同时又对油气生产企业和下游用户产生较大的影响。 |
| 9. | Abstract : according to the characteristics of solid - liquid two - phase flow , the equation of motion and the equation of continuity for hammer computation are deduced in this paper . the equations are applied to analyze the effect of different prevention deveces used to relieve water hammer pressure in pipeline transport with displacement pumps . it is concluded that the air vessel and pressure relief valve are better than other devices 文摘:本文针对固液两相流的特点,建立了水击计算的运动方程及连续方程,并采用新方程对矿山常采用的容积泵输送中使用的储气罐、泄压阀、缓闭逆止阀等减缓水击压力的防护措施进行了计算分析,得出储气罐、泄压阀减压效果最好的结论。 |
