摘要
目前,运行中的泵普遍存在出口压力过高、与系统不匹配、调节阀节流严重、调节阀阀座冲刷严重、管道振动大、噪音大等问题,其根本解决方法就是对凝结水泵抽叶轮进行改造,从而降低凝泵出口扬程。改造后,水泵的工况可满足机组负荷需要及凝结水泵性能的要求。
At presemt,There are some general problems with the running pump, such as excessive outlet pressure,the pump does not match with the system, the throttle and erosion of control valve is serious, too much vibration, noise of piping and other issues, the most fundamental way is to change the export of condensate pump head, which will reduce condensate pump outlet head.After transforma- tion, the load conditions of pump unit can meet the needs and condensate pump performance requirements.
