摘要
由于公司3号、4号机组前置泵机械密封冷却水质差,经常造成设备紧急停运。为了解决这个问题,把前置泵机械密封改为填料式密封,把冷却水由工业水改为凝结水和除盐水,通过改造使主设备处于良好的运行或备用状态,确保了主机安全稳定运行。
As the company # 3 # 4 units pre-cooling water pump mechanical seal poor, often caused by equipment outage emergency. To solve this problem, the pre-pump mechanical seal packing seal is replaced, the cooling water from industrial water changed in addition to condensation of water and saline. Through the transformation, the main device is in good running or standby mode, ensuring safe and stable operation of the host.
