石油、化工等厂矿所用的各种旋转式压缩机、鼓风机、通风机、汽轮机、泵、电机及其他旋转机械等,在工艺操作上都起着重要的作用。其中压缩机、汽轮机等价格比较昂贵,国外一般都不配备用机组(我国进口装置的这类设备也是如此),而且须满足连续运行3年的要求。如果设备一旦发生故障,小则影响机械设备的工作性能和使用寿命、产生有害的振动、噪声和对构筑物带来影响;大则使整个装置或工厂停工减产,造成经济上的巨大损失,甚致造成重大设备毁坏和工伤事故。因此,一定要安全可靠,能长周期操作,并有能检测故障的手段,及早采取措施。
All kinds of rotary compressors, blowers, ventilators, steam turbines, pumps, motors and other rotating machinery used in oil and chemical factories and mines play an important role in the process operation. Compressors, steam turbines and other more expensive, generally not equipped with foreign units (such as China’s imports of such equipment is also true), but also to meet the requirements of continuous operation for three years. In the event of equipment failure, small machines will affect the working performance and service life of machinery and equipment, resulting in harmful vibration, noise and impact on the structure; the greater the entire plant or plant down production, resulting in huge economic losses, even Cause major equipment damage and work-related accidents. Therefore, we must be safe and reliable, long-cycle operation, and have the means to detect failures, early measures.
