深圳水库电站2号水轮发电机组是韶关水轮机厂的产品,发电机型号为TS286/42-28,额定功率1600kW,额定转速214r/min。该机于1985年12月试运行时产生较大的噪声和振动,经过测试处理后取得较好效果,现将噪声的测试结果、原因分析和处理方法简介如下。(一) 机组运行及噪声、振动测试情况发电机空载运行时,机组各部摆度、振动和瓦温均符合标准。随着机组的负载增加,噪声和振动也随着增加,当负载升至1400kW时,噪声达86dB,连厂房玻璃窗也发出吱吱响声,严重影响运行人员的正常
Shenzhen Reservoir Hydropower Station No. 2 Shaoguan turbine plant products, generator model TS286 / 42-28, rated power 1600kW, rated speed 214r / min. The machine in December 1985 when the trial operation produces large noise and vibration, after the test and get better results, now the noise test results, the reasons for analysis and treatment methods are as follows. (A) unit operation and noise, vibration test conditions Generator no-load operation, the units of the Ministry of swing, vibration and tile temperature are in line with standards. As the unit load increases, the noise and vibration also increase. When the load rises to 1400kW, the noise reaches 86dB. Even the glass windows of factory buildings emit squeaky noise, which seriously affects the normal operation of the operators
