Pump hydraulic turbine problems
Thread Content
In diesel and gasoline hydrogenation units, the reaction feed pump is of the hydraulic turbine type; high-pressure oil enters the low-pressure separator after doing work through the hydraulic turbine. I would like to ask fellow users: what is the minimum opening degree of the control valve for allowing high-pressure oil to flow into the turbine? In other words, what is the minimum valve position that prevents the coupling from coming apart? Are there any other users with similar experience? ! Our high-pressure threshold is 6.2 MPa, and the low-pressure threshold is 2.6 MPa. Colleagues who have experience or relevant information in this area are welcome to leave a message. Thank you
1. The hydraulic turbine curve provided by the manufacturer shows the approximate range. 2. As indicated in the figure, a power value of 0 serves as the boundary; a power value greater than 0 indicates that the hydraulic turbine begins to do work, with the turbine’s speed being equal to or greater than that of the pump. 3. The hydraulic turbine parameters shown in the attached diagram do not meet the owner’s requirements; this is provided for reference only
