Based on an axiomatic theory of hull-propeller interaction a condition for optimum propulsion is derived and subsequently the principal parameters of the propeller conceived as a pump stage are obtained in a preliminary design procedure. 基于Schmiechen的船体/螺旋桨相互作用的理论导出了最佳推进条件。随之将螺旋桨设想为泵,在初步设计过程中求得桨的主要参数。
How to Improve Installation Efficiency of Large and Medium Propeller Pump 浅谈提高大中型轴流泵装置效率
Describe the oil-absent of shaft chamher, fan propeller drop, and other problems were effectively solved by technology improvement of solid caustic submerged pump which produced by our plant, and assure the regular production. 通过对我厂自制固碱液下泵的技术改造,有效地解决了轴承室缺油、叶轮脱落等问题,确保我厂固碱的正常生产。
