【摘要】 提出了一种适合于输送含颗粒、腐蚀性介质的自吸泵。它具有结构简单，铸造容易，性能可靠的特点。提出以封液厚度的概念替代储液高度，以动态液面替代静态液面的概念，来确定气水分离室几何尺寸的方法，并论证了该方法的合理性和可行性。更多还原

【Abstract】 A kind of self priming pumps suitable for special media is presented in this pa-per,which has simple construction and reliable performance.The concepts of sealing media thickness and variable mediucm interface are introduced to substitute for the comcepts of stored medium height and stationary medium interface,respetively,as to be used for determining the geometry of medium interface.更多还原
