冷凝泵的工作部件
单级:主要部件为叶轮由硅黄铜80-3制成,通过键固定在45优质碳制成的轴上,叶轮装在由耐磨铸铁HT20-40和泵体盖组成的泵室之中,动力机器驱动轴承之中支撑的轴和叶轮通过联轴器,泵工作。耐磨铸铁HT20-40制成的轴套与衬套(6n6和4n6x2)一起起到水润滑滑动轴承的作用,泵体前面的填料函配有填料环和油浸石墨石棉绳。开式填料压力为盖。填料在加长双头螺栓的帮助之下被压缩,并且可以调整紧密度。从内部引入高于大气压的密封水。连接管与填料环对齐,整个填料函之内形成密封腔,以防止空气进入泵,同时防止泵之内的水向之外流动,只有少量润滑水流出。329之上开有一个平衡孔,使高压区与进口处的低压区连通,以消除轴向推力。为了防止泵体和泵盖的磨损,在泵体和泵盖之上安装了一个密封圈,泵体的上部配有一个用于放气的螺孔。停泵检修时,泵内的水从螺孔排出,为了便于泵体和泵的拆卸,在泵的进口和出口

Working parts of condensate pump
Single stage: the main component is the impeller, which is made of silicon brass 80-3 and fixed on the shaft made of 45 high-quality carbon by keys. The impeller is installed in the pump chamber composed of wear-resistant cast iron HT20-40 and the pump body cover. The shaft and impeller supported in the drive bearing of the power machine work through the coupling. The shaft sleeve made of wear-resistant cast iron HT20-40 plays the role of water lubricated sliding bearing together with the bushing (6n6 and 4n6x2). The stuffing box in front of the pump body is equipped with packing ring and oil immersed graphite asbestos rope. Open packing pressure is cover. The packing is compressed with the help of extended studs and the tightness can be adjusted. Introduce sealing water higher than atmospheric pressure from the inside. The connecting pipe is aligned with the packing ring, and a sealing cavity is formed in the whole stuffing box to prevent air from entering the pump and prevent water in the pump from flowing outward, and only a small amount of lubricating water flows out. 329 is provided with a balance hole to connect the high-pressure area with the low-pressure area at the inlet to eliminate the axial thrust. In order to prevent the wear of the pump body and cover, a sealing ring is installed on the pump body and cover, and the upper part of the pump body is equipped with a screw hole for bleeding. When the pump is stopped for maintenance, the water in the pump is discharged from the screw hole. In order to facilitate the disassembly of the pump body and the pump, the inlet and outlet of the pump
