diffuser pump

基本解釋

The numerical results indicate that 1) Phase differences in time of flow velocities and backflows occur across section of diffuser connecting to pump chamber;
數(shù)值結果表明：1）在微泵擴散管的過流截面上流速有時間相位差和回流現(xiàn)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.
還給出微泵流量與擴散管長寬比、厚寬比、液體粘度和進出口反壓差的定量關系。
A brass impeller surrounded by a cast iron diffuser, bracket, and case makes this pump as strong as those used by your grandfather!
泵的黃銅葉輪由鑄鐵擴散器、支架和外殼包圍，使泵非常堅固耐用！
