( 2 )采用平板型支撑液膜,测定各种操作条件下的渗透系数p 。
Pigging in pipe before inspection , pipe pigging under low throughput intermittent operation ; get rid of congealable oil , wax precipitation and incrustation in pipe to reduce backpressure and friction , and lower temperature
管线内检测前清管、低输量间歇运行输油管线清管；清除管线内部的凝油、结蜡、结垢，达到减小输油回压、减小磨阻、降低输油温度的目的。
Life is the main factor restricting air valve and spring - loaded valves quality , the general long - term continuous operation of the compressors to life 80 hours ; for mobile , short - term or intermittent operation of compressors , may require slightly more
限制气阀寿命的主要因素是阀片及弹簧质量，一般对长期连续运转的压缩机，希望寿命达8000小时以上；对移动式、短期或间歇运转的压缩机，要求可稍低些。
By way of analysis of heat transfer process of the field - test model , the author formulated a 3 - dimensions heat transfer model which is correspondent to actual performance of buried pipe - in - pipe heat exchanger . coupled with field testing data , the short and long term operation features has been thoroughly analyzed by finite element solution and forward finite - difference analysis of the heat transfer differential equations of buried pipe - in - pipe heat exchanger . by interpreting regularity of continuous and intermittent operations of buried pipe - in - pipe heat exchanger , its heat transfer mechanism has been further explained in this thesis
本文通过对试验模型热过程的深入分析，建立了与实际地下埋管换热器结构参数相吻合的三维传热数学模型，通过有限单元法和向前差分法求解相应微分方程并对分析结果进行关联耦合，详细分析了埋管换热器的短期和长期运行特性，对地源热泵套管式埋管换热器连续运行、间断运行规律进行了解析，进一步弄清了埋管换热器的传热规律。
