Quantitative relations of the pump flow rate versus the ratio of diffuser length to width, the ratio of diffuser thickness to width, fluid viscosity and backpressure were also given.
还给出微泵流量与扩散管长宽比、厚宽比、液体粘度和进出口反压差的定量关系。

A brass impeller surrounded by a cast iron diffuser, bracket, and case makes this pump as strong as those used by your grandfather!
泵的黄铜叶轮由铸铁扩散器、支架和外壳包围，使泵非常坚固耐用！

The numerical results indicate that 1) Phase differences in time of flow velocities and backflows occur across section of diffuser connecting to pump chamber;
