我省湘农型水泵在设计上大多数泵是具有结构紧凑、重量轻、效率高等优点,但由于前几年内把水泵产品下放到各地区自行生产,有不少厂根本不具备生产条件,加上工厂领导在思想上对质量不够重视,因而生产的水泵质量较差,既浪费能源又损害农民的经济利益,经济效果是不好的。根据水泵制造中存在的问题和多年实践证明,提高水泵质量,应抓好以下几项工作: (一)抓铸件质量,保障水力效率。排灌机械的铸件约占90～95％,主要零件泵体、叶轮是组成水泵的关键件,其过流道都是不加工的,流道光洁度对水力效率影响很大。所以我们必须抓好铸件质量。要注意三个环节:
Hunan Province, agriculture-type pumps in the design of most pumps is a compact, light weight, high efficiency, but a few years ago the pump products decentralized to various regions of their own production, there are many plants simply do not have the production conditions, plus On the factory leaders did not pay enough attention to the quality of the ideology, so the quality of the pump produced is poor, not only a waste of energy but also damage the economic interests of farmers, the economic effect is not good. According to the problems in the pump manufacturing and years of proven, to improve the quality of the pump, should do a good job in the following: (A) grasp the quality of castings to ensure hydraulic efficiency. Drainage and irrigation machinery casting accounts for about 90 to 95%, the main parts of the pump body, the impeller is the key components of the pump, the over-flow channel is not processed, the flow channel finish has a great impact on hydraulic efficiency. So we must do a good job casting quality. Pay attention to three aspects:
