水轮泵是我国独创的优良提水机械,在我区农业提灌事业中占有重要地位。目前全区拥有13500台,保灌农田近100万亩,对促进农业增产和繁荣社会主义新农村起了积极作用。随着单机容量扩大、串连台数增多和扬程提高,水轮泵沿用的钢质滚动轴承,由于密封问题不易解决,逐渐暴露了不适应水下运行的弱点:在水流冲刷、泥沙侵袭之下,钢轴承中的黄油容易流失,造成润滑条
Waterwheel pump is our unique excellent water lifting machinery, agricultural irrigation in our region occupies an important position. At present, there are 13,500 units in the whole region, covering nearly 100 million mu of farmland and playing an active role in promoting agricultural production and prospering new socialist countryside. With the expansion of stand-alone capacity, the number of serially connected units and the rise of lift, the steel rolling bearings used for waterwheel pumps have gradually exposed the weaknesses that are not suitable for underwater operation due to the sealing problem. Under the conditions of water scour and sediment attack, The loss of butter in steel bearings is likely to result in lubricating strips
