我省共有一万四千多处提灌站,约有各种类型的水泵二万台,由于这些提灌站大部份在黄河干流和支流上提水,扬程高、泥沙含量大,水泵气蚀磨损严重,一台新泵一般使用不到八年就报废,仅为正常使用年限的一半时间。近年来,经过试验研究,用环氧金刚砂涂料涂护一次,一般可延长使用年限二年,连续涂护四次使用年限等于一台新泵,且每次涂护花的费用很少。
There are about 14,000 irrigation stations in our province, with about 20,000 types of pumps of various types. As most of these pumping stations raise water in the main stream and tributaries of the Yellow River, with high head and large sediment contents, pump cavitation Severe wear and tear, a new pump is generally used less than eight years to scrap, only half the normal life of the time. In recent years, after an experimental study, coated with epoxy diamond coating once, the general extension of the useful life of two years, four consecutive years of service life equal to a new pump, and the cost of each coating flowers rarely.
