Research on the Application of Direct Drinking Engineering Based on Pipeline Water Distribution Technology and Pump Machinery Maintenance
In the pipeline water distribution technology for direct drinking projects,there are certain shortcomings in the design consideration of the water supply pressure of high-place water supply pipelines,and there is still little design in this aspect.This study designs a saddle-shaped pipeline water distribution technology based on the prin-ciple of giving priority to high-place water supply,which takes the tee of the same diameter as the core to maxi-mize the efficiency of high-place water supply.In addition,this paper studies the mechanical maintenance and seal-ing technology of water pumps for direct-drinking water pumping stations,and designs experiments to verify it.The results show that the proposed mechanical seal technology for water pumps exhibits more significant wear losses,with stainless steel and rubber wear losses of 1.22 and 0.24,respectively,the wear life of the mechanical seal reaches 4.9 a when the reliability level is around 0.98,and that installing the saddle-shaped water distribution pipe-line has a more efficient and stable water supply.Experiments have verified that this technology can achieve up to 98.3%of the water supply efficiency output of high-rise buildings.This study provides technical reference for high-place water supply and pump maintenance in direct drinking engineering.
