我们渭惠渠高塬灌区共二十二个抽水站,是一九五八年大跃进时兴建的。由于渭河水含砂量大(一般在2～8%之间),泵的使用扬程高,水泵的磨损相当严重,叶轮、密封环等损坏很快,甚至会影响到泵体,发生穿孔等现象。为了解决这个问题,我们从一九六四年就开始使用环氧材料修补水泵。近十年来,有将近一百台机组(最大的是32Sh—19离心泵)基本上都多次进行了环氧材料的修补。目前台台机组都在继续使用,确保了机组高效低耗的运行。使用环氧材料修补
Twenty-two water pumping stations in the Wehuiqu highland irrigation area were built during the Great Leap Forward in 1958. Due to the large amount of water and sand in the Weihe River (generally between 2 and 8%), the use of the pump is very high, and the wear on the pump is quite serious. The impeller, seal ring and other damage are very rapid, even affecting the pump body and perforation. . In order to solve this problem, we started repairing pumps with epoxy in 1964. Nearly a decade, nearly 100 units (the largest is 32Sh-19 centrifugal pump) are basically repeated epoxy material repair. Taiwan and Taiwan are currently continuing to use the unit to ensure the efficient operation of low-cost unit. Use epoxy repair
