摘要
DG2 70 1 4 0B高压给水泵为沈阳水泵厂早期定型产品 ,是热电厂、供热厂热介质 (水、汽 )系统的心脏 ,在很多热电厂使用。由于特殊工况及设计上存在不足 ,该产品经常出现密封填料泄漏、振动及推力瓦块烧熔等故障。对此 ,介绍几种行之有效的检修改进技术。
DG 270-140B type high-pressure feed-water pumps are early typical products of Shenyang Water Pumps' Factory, being widely used in many power plants. Due to special oparating conditions and insufficiency existing in the design, such faults as seal packing leakage, vibration, and burn-melting of thrust bearing shoe etc. have frequently occurred. For this reason, several effective repair techniques are recommented.
