针对油田热电厂9台凝结水泵电动机出现的本体温升高、振动值超标、轴承损坏等问题的原因进行分析,对处理的过程进行总结,并从电动机的安装和检修等方面的预防措施进行探讨,为保证同类型立式推力式高压电动机安全稳定运行提供可借鉴的经验。凝结水泵是汽轮发电系统的主要设备之一,其所用电动机是由湘潭电机厂生产型号为YL355-4、容量为250kW、电压等级为6kV的立式推力式电动机,它是影响油田热电厂安全经济运行的一个重要环节。近几年,油田热电厂9台凝结水泵电动机陆续出现电动机过电流、过热、振动值超
Aiming at the causes of the problems such as the increase of body temperature, excessive vibration value and bearing damage of the nine condensate pump motors in the oilfield thermal power plant, the process of the problems is analyzed, and the preventive measures such as the installation and maintenance of the motor are discussed. In order to ensure the same type of vertical thrust high-voltage motor safe and stable operation can provide reference experience. Condensate pump is one of the main equipment of steam turbine power generation system. Its motor is manufactured by Xiangtan Electric Machine Co., Ltd. Model YL355-4 with a capacity of 250kW and a voltage level of 6kV. It is a kind of vertical thrust motor that affects the thermal power plant An important part of running. In recent years, oil-field thermal power plant 9 condensate pump motor motor overcurrent, overheating, vibration value ultra
