Analysis of the Effect of in-Late Angle and Lower Valve Position in the Semi Jet Type Water Pump Installation Against Water Debit

Jurnal Serambi Engineering, 2023
The problem that often occurs in people who use semi-jet water pumps is that when the installation of the water pump has been completed, it turns out that the water discharge cannot flow as expected and the electricity consumption is quite large.

Cavitation in Water jet Pumps

Bulletin of JSME, 1979
Based on the similarity law of jet pump, a new cavitation parameter σ is proposed which has the similar meaning to Thoma's cavitation parameter in turbo pumps. The σ values are determined theoretically and presented as the function of specific speed nsj so that we may predict cavitation directly by using it in the designing. Experiments are carried out

Possibilities of 3D machining of materials by abrasive water jets [PDF]

, 2019
Machining of materials through classical way, i.e. using conventional tools for turning, drilling, milling, grinding and polishing, has some limits that can be overcome applying an abrasive water jet (AWJ). Therefore, some possibilities of 3D machining
