Description
技术领域technical field
本实用新型涉及机电设备领域，尤其涉及一种汽轮机液压调速装置。The utility model relates to the field of electromechanical equipment, in particular to a hydraulic speed regulating device of a steam turbine.
背景技术Background technique
汽轮机也称蒸汽透平发动机，是一种旋转式蒸汽动力装置，也是现代火力发电厂的主要设备。其工作原理是高温高压蒸汽穿过固定喷嘴成为加速的气流后喷射到叶片上，使装有叶片排的转子旋转，同时对外做功。汽轮机转速与发电频率有关，故而要求其转速恒定，而其转速恒定的实现，一般是通过对于喷嘴的开度调节来实现。而目前的开度调节往往存在设计欠合理的情况，导致开度调节机构使用寿命较短且需要频繁维护，针对以上问题，目前还缺少对应的解决手段或者说设备。Steam turbine, also known as steam turbine engine, is a rotary steam power plant and the main equipment of modern thermal power plants. Its working principle is that the high-temperature and high-pressure steam passes through the fixed nozzle to become an accelerated airflow and then sprays onto the blades, so that the rotor equipped with the blade row rotates and does external work at the same time. The speed of the steam turbine is related to the power generation frequency, so the speed of the steam turbine is required to be constant, and the realization of the constant speed is generally realized by adjusting the opening of the nozzle. However, the current opening adjustment often has unreasonable design, resulting in a short service life of the opening adjustment mechanism and frequent maintenance. For the above problems, there is currently a lack of corresponding solutions or equipment.
