随着苏联造船工业的发展,在船舶系统中广泛得到应用的离心泵的生产也正在逐步增长。譬如莫斯科加里宁水泵厂在1975年的水泵产量就将比1971年生产的3345台增加1500台。为了完成预定的计划,就要在试制新结构和改进老结构方面作出努力以提高泵的可靠性和使用寿命,改善其动力指标和汽蚀指标,缩小体积,改善结构外形和使维护工作简化。要想提高泵的使用期限,就需要对其工作机构采用比较可靠和耐用的材料。对于在海水中工作的水泵另件来说,材料
With the development of the Soviet shipbuilding industry, the production of centrifugal pumps, which are widely used in marine systems, is also gradually increasing. For example, the pump production at Moscow Kalinin Pump Plant will increase by 1,500 units from the 3,345 units produced in 1971 in 1975. In order to complete the planned program, efforts should be made to try out the new structure and improve the old structure to improve the reliability and service life of the pump, to improve its dynamic and cavitation targets, to reduce the size, to improve the structural appearance and to simplify the maintenance work. To improve the life of the pump, it is necessary to use more reliable and durable materials for its work organization. For other parts of the pump working in seawater, the material
