GE IS200ACLEHEX2100 系统燃机卡

GE IS200ACLEHEX2100 汽轮机又称蒸汽透平发动机，是一种旋转式蒸汽动力装置。高温高压蒸汽通过固定喷嘴，变成加速气流，喷射到叶片上，使带叶片排的转子旋转，对外做功。汽轮机是现代火力发电厂的主要设备，也用于冶金工业、化学工业和船舶电站。汽轮机的结构部件由转动部件和固定部件组成。

GE IS200ACLEHEX2100 Turbine, also known as steam turbine engine, is a rotating steam power unit. High-temperature and high-pressure steam passes through a fixed nozzle and becomes an accelerated airflow, which is injected onto the blades, causing the rotor with blade rows to rotate and do work externally. Turbine is the main equipment of modern thermal power plant, also used in metallurgical industry, chemical industry and ship power station. The structural parts of the turbine consist of rotating parts and fixed parts.

GE IS200ACLEHEX2100 转子包括主轴、叶轮、动叶片和联轴器。联轴器。定子包括进汽部分、汽缸、隔膜和定子级联、汽封和轴承等。

GE IS200ACLEHEX2100 The rotor consists of the main shaft, impeller, moving blades and coupling. Coupling. The stator includes the steam inlet section, cylinder, diaphragm and stator cascade, steam seals and bearings.

汽缸隔热不良。如果汽缸的隔热性能较差，在汽轮机启动和停机时，上下汽缸的温差会很大。在汽轮机启动和停机过程中，上缸和下缸会产生较大的温差。一般情况下，上缸的温度高于下缸的温度，这使得上缸在启动和停机过程中会产生较大的温差。一般情况下，上缸温度高于下缸温度，使得上缸膨胀高于下缸，上缸拱起。

Causes of bending of turbine electromechanical spindles

Poor cylinder insulation. If the cylinders are poorly insulated, the temperature difference between the upper and lower cylinders will be large during turbine startup and shutdown. During startup and shutdown of the turbine, a large temperature difference is generated between the upper and lower cylinders. Generally, the temperature of the upper cylinder is higher than that of the lower cylinder, which causes a large temperature difference between the upper cylinder during startup and shutdown. Generally, the temperature of the upper cylinder is higher than that of the lower cylinder, which makes the upper cylinder expand higher than the lower cylinder and the upper cylinder arch.
