  四、?简答题:? 2.调节阀的理想流量特性取决于什么?工作流量特性又取决于什么? 答案:理想流量特性取决于阀芯形状。工作流量特性取决于阀芯形状和配管状况。 3.定位器和调节阀阀杆连接的反馈杆脱落时,定位器的输出如何变化? 答案:定位器和调节阀阀杆连接的反馈杆脱落时,定位器就没有了反馈,成了高放大倍数的气动放大器。如果定位器是正作用,即信号增加,输出也增加,则阀杆脱落,输出跑最大。如果是反作用,则跑零。 4.试述差压式流量仪表的测量原理。 答案:差压式流量计是基于流体流动的节流原理,即利用流体流经节流装置时所产生的压力差而测量流量的。 5.比例调节规律的含义是什么? 答案:比例调节是依据‘偏差大小’来动作的;其输出和输入偏差大小成比例。 6.积分调节规律的含义是什么? 答案:积分调节是依据‘偏差是否存在’来动作的;其输出与偏差对时间的积分成比例。 7.微分调节规律的含义是什么? 答案:微分调节是依据‘偏差的变化速率’来动作的;其输出与输入偏差的变化速率成比例。 8.什么是生产过程的调节? 答案:为了保持参数的规定值,就必须对工艺过程进行控制,以消除这种偏差,使参数回到规定值点,这种控制过程就叫做生产过程的调节。 9.选择测量元件的安装点时应注意什么? 答案:应合理地选择测量元件的安装地点,尽可能地缩短纯滞后的时间。 ?19.DCS与常规仪表相比有哪些优点? 答案:1.功能丰富??2.系统可靠性高?3.集中监视.操作和管理?4性价比高?5.安装工作量小?6.硬件结构采用积木式?7.控制方案易于修改 ?26.热电阻温度计的工作原理?哪些材料常用来做热电阻? 答案:热电阻温度计利用了导体或半导体的电阻值随温度而变化的性质。常用的热电阻有铂电阻和铜电阻。 27.校验仪表时,校验点应选多少? 答案:应选量程的0%,25%,50%,75%以及100%。 43.差压变送器测液面,如何标定零点? 答案:先关闭正负取压一次阀,将正负引压管中注满隔离液,调整零点,使其符合要求。 46.标准节流装置的使用条件是什么? 答案: ⒈被测介质应充满全部管道截面连续流动; ⒉管道内的流束(流动状态)应该是稳定的; ⒊被测介质在通过节流装置时应不发生相变; ⒋在节流装置前后应有足够长的直管段。 48.智能表与常规表的区别有哪些? 答案: 1.精度高 2.信号采用数字传输,抗干扰强 3.量程范围大 4.自诊断功能 5.调校方便. 50、控制点的正反作用是怎样规定的? 答案:当控制点的输入偏差信号增加时,控制点的输出也增加,称之为正作用;反之,控制点的输出信号随偏差的增加而减小的称为反作用。 五、?论述题: 1、?热电偶输出不稳定,试说出至少三条可能原因。 答案: ①、热电极将断未断 ②、热电偶接线柱与热电极接触不良 ③、热电偶测量线路引起断续短路或接地 ④、外界干扰(电磁感应等) 2、热电偶测温时为什么需要进行冷端补偿? 答案:①热电偶热电势的大小与其两端的温度有关,其温度-热电势关系曲线是在冷端温度为0℃时分度的。 ②在实际应用中,由于热电偶冷端暴露在空间受到周围环境温度的影响,所以测温中的冷端温度不可能保持在0℃不变,也不可能固定在某一个温度不变,而热偶电势既决定于热端温度,也决定于冷端温度。所以如果冷端温度自由变化,必然会引起测量误差。为了消除这种误差,必须进行冷端温度补偿。 3、调节器的输出值随测量值的增加而增加,为正作用,反之,为反作用。此说法是否正确,并说明其原因。 答案:此说法不正确。调节器的输出值随正偏差的增加而增加,为正作用,而调节器的输出值随正偏差的增加而减少,为反作用。 4、有一台正在运行中的气关阀,总是关不死,试说出至少五条可能的原因。 答案: ⒈阀芯、阀座间磨损严重; ⒉阀芯、阀座间有异物卡住; ⒊调节阀膜头漏气; ⒋零点弹簧预紧力过大; ⒌阀杆太短; ⒍调节阀前后压差过大; ⒎定位器输出达不到最大。 5、为什么在温度调节系统中,普遍增加微分调节作用? 答案:对于滞后较大的系统,增加微分作用可以提高调节系统的质量。在这种情况下,当调节器感受到偏差时,实际上干扰已经作用了一段时间,因而适当加大一些输出会有利于克服干扰已产生的影响。有利于抑制偏差的继续增长。对于温度调节系统来说,滞后较大,所以应加入适当的微分作用。 ?8、什么是DCS? 答案:?DCS也称集散控制系统,它是利用计算机技术、控制技术、通信技术、图形显示技术实现过程控制和过程管理的控制系统。 9、什么叫绝对压力、大气压、表压及真空度? 答案:绝对真空下的压力称为绝对零压,以绝对零压为基准来表示的压力叫绝对压力。 测量流体压力用的压力表的读数叫表压,它是流体绝对压力与该处大气压力的差值。 如果被测流体的绝对压力低于大气压,则压力表所测得的压力为负压,其值称为真空度。 10、什么叫差压变送器的静压误差? 答案:向差压变送器正、负压室同时输入相同的压力时,变送器的输出零位会产生偏移,偏移值随着静压的增加而发生变化,这种由于静压而产生的误差,称为静压误差。 ?14、灌隔离液的差压流量计,在开启和关闭平衡阀时应注意些什么? 答案:对于灌隔离液的差压流量计,在启用前,即在打开孔板取压阀之前,必须先将平衡阀门切断,以防止隔离液冲走。在停用时,必须首先切断取压阀门,然后方可打开平衡阀门,使表处于平衡状态。 15、仪表引压管路的长度有无规定,以多长为好? 答案:为了保证仪表的测量精度.减少滞后,管路应尽量短。但对高温高压的蒸汽,为了能使其充分冷凝,要求测量管路有一定的长度;对脉动较大的介质,也要求测量管路有一定的长度,以使波动平稳。但最长不应大于50m。 16、用孔板测量流量,孔板装在调节阀前为什么是合理的?[T/] 答案:①用节流装置测量流量时,理论上有两个要求,即流体流动是连续的,并且流体流动过程中遵守能量守恒定律。这就告诉我们孔板不能安装在气液两相并存的地方,以免增大测量误差。 ②有的液体(如液化烃)经调节阀降压后,布袋除尘器金誉彩票分析有时会有部分气化,形成两相共存。因此,流量孔板?应尽量安装在调节阀前,这种安装方式是合理的。 17、论述差压变送器的投用过程。 答案:①检查差压变送器的正、负压阀是否关闭,平衡阀是否打开; ??②开启排污阀。缓缓打开一次阀门冲洗导管,冲洗后关闭排污阀,一般冲洗不少于两次; ③待导管冷却后,才可启动仪表,若管路中装有排空阀应先开启一下排空阀,排除空气后方可启动仪表; ④渐渐开启变送器正压门,当测量介质为蒸汽或液体时,待充满凝结水或液体时,松开变送器正、负测量室排污螺钉,待介质逸出并排净空气后拧紧螺丝钉,然后检查是否渗透漏并检查仪表零点; ⑤关闭平衡阀,逐渐打开负压阀。
