Examples
- There should be a main valve between mother tube boiler and steam mother tube , which should be in remote control
6母管制机组的锅炉与蒸汽母管之间应有主汽阀，主汽阀要实现远方控制。 - On series thermodynamic system , this paper studies about that how to make the cycling water warm serially and reform the negative - voltage unit
对于所研究的母管制热力系统，本文讨论了如何实行循环水串联供热的问题。 - Water supplying pipe in front of the coal economizer should be installed with a stop valve and check valve for the factory using boiler of mother tube water supplying
7采用母管制供水的电厂，进入每台锅炉省煤器前的给水支管均应装设截止阀与逆止阀。两阀应紧接，按水流方向逆止阀在前。 - It is indicated that , when a two - speed motor is used for driving oil transfer pump , the motor with the characteristic of torque reduction on square rotary speed should be chosen ; the working economy of the variable speed pump is restricted by the characteristic curves of pipeline resistance , and its speed control range is restricted by the pipeline resistance characteristic curve , the pressure head needed by the system and the working characteristic of the pump ; when several pumps work in parallel , the pump with better performance should be changed into speed - variable pump
指出双速电动机用于输油泵的调速时，应选用转矩按转速平方降低特性的电动机；调速泵的运行经济性受到管路阻力特性曲线的限制，其调速范围受到管路阻力特性曲线、系统所需扬程和泵运行特性的限制；在母管制系统中把部分定速泵改为调速泵时，应将性能较高的定速泵改为调速泵。 - The paper concerns thermal systems of a main piping structure used in the petrochemical or electric power industry . in this paper , the conventional optimal dispatch approach is introduced first and its inability in application is pointed out on the basis of an analysis of the corresponding optimal dispatch model . therefore , on - line adaptive optimal dispatch is put forward with the need of improving the automatization level of power stations , and some major problems involved are discussed in details in this paper
以母管制热力系统为研究对象，本文首先介绍了通常所采用的优化调度方法，并通过分析所建立的优化调度模型指出了这种方法在实际应用中的不足，并结合电站自动化发展的要求提出了在线自适应的优化调度方法，就其中所涉及的一些主要问题进行了深入的研究。
