Abstrac

 
The pump is a kind of common transmission fluid mechanical, phyletic and various applications, for our production life has an important influence on, it has small, simple structure, easy operation, low operating costs, the pump efficiency high, safe and reliable operation, long service life, and many other advantages, widely used in petroleum industry transport gasoline, kerosene, diesel oil and petroleum products and other industry similar medium transmission, and conveying fine pulp centrifugal pump as a main size conveyor machinery, in the oil industry has an important position. This paper introduces the design YG type vertical single grade single straw way centrifugal pump process, mainly is suitable with centrifugal pump motor of choice, the impeller and blade design calculation, pump cavitation phenomenon, water pressure room, water-obsorbing room choice and the arrangement, pump parts of intensity and packing seal of the pump and overall design and arrangement. According to the character of the flow of fine pulp and practical problems, from set out actually consider all aspects of the problem, to meet the basic requirements of pump, make the design of reasonable structure, good performance.
