1) 3-casing 4-exhaust
三缸四排汽
1.
This paper introduces structural characteristics of two types of steam turbines,such as 3-casing 4-exhaust and 2-casing 2-exhaust,which are used in direct air-cooled 660 MW supercritical units,economy targets under typical working conditions,and structural characteristics of main workshop,etc.
本文简要介绍了660MW超临界直接空冷机组三缸四排汽和两缸两排汽汽轮机的结构特点、典型工况下的经济指标和主厂房结构特点等。
2) three-casing double flow turbine
三缸双排汽汽轮机
3) four-cylinder triple-expansion engine
四缸三胀式蒸汽机
4) exhaust hood
排汽缸
1.
However, most of the previous numerical simulations studied the exhaust hood separately without taking account of the effect of the inhomogeneous flow from the last stage.
数值模拟一直是研究大功率汽轮机低压排汽缸内流场的主要方法之一。
2.
As the computational domain includes exhaust hood and last two stages,it is difficult to obtain precise results using the single-block grid,so the multi-block mesh is adopted to get the detailed three-dimensional flow in exhaust hood.
对于汽轮机低压排汽缸和末两级耦合的流场来说,单块网格难以保证计算的准确性。
3.
Through the numerical study on the complicated 3-D flow field of steam turbine exhaust hood,the status and progress at home and abroad on the numerical study is reviewed in detail and expected to promote the study on numerical study and project application.
通过对汽轮机排汽缸通道内三维复杂流动数值研究的分析和整理,综述了国内外排汽缸数值研究现状及进展,以期对此方面的研究及其工程应用起到促进作用。
6) cylinder drainage
汽缸排泄
补充资料：阻汽排水阀
分子式：
CAS号：
性质：又称疏水器，阻汽排水阀，冷凝水排除器。自动排放冷凝水并阻止蒸汽泄漏的阀门。型式较多，根据操作原理可分为两种：（1）自动排水式。借蒸汽本身的压力将冷凝水排出，例如浮球式疏水阀、浮杯式疏水阀、孔板式疏水阀等。（2）压出式疏水阀。借外加蒸汽压力将冷凝水排出。根据操作方法分为两种：（1）连续式疏水阀，例如浮球式疏水阀、孔板式疏水阀、压出式疏水阀。（2）间歇式疏水阀，例如浮杯式疏水阀。
