diffuser pump

基本解释

The numerical results indicate that 1) Phase differences in time of flow velocities and backflows occur across section of diffuser connecting to pump chamber;
数值结果表明：1）在微泵扩散管的过流截面上流速有时间相位差和回流现象。
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！
