Does anyone know of projects where vertical turbine pumps have been installed? We are currently designing a pump station and have different options on the type of pumps we can use. One of the options comprise vertical turbine pumps. This prove to be the most cost effective option when compared...
Usually we would size the blow-off and air-intake requirements simultaneous as sizing the blow-off too big might cause negative pressures in the pipeline if the air valves are too small. To calculate the time to drain the pipe is not so easy (i think). On big pipelines, say 2m diameter, this...
Has anyone sized a blow-off valve based on the time it will take to empty a section of pipeline? The flow rate varies according to the water height which changes with time. The slope of the pipe(s) aslo has an effect of the total drainage time. Usually there are several pipe slopes up-stream...
Good day,
Does anyone know where i can find information on how to design a 3D thrust-block. The pipeline that we are designing have composite vertical and horizontal bends.
Thank you.
Thank you for the information.
At the pump station we catered for expansion with flexible couplings direct to the pump suction and pump discharge sides. Thrusts at bends and check valves are taken up by anchor blocks to ensure that no loads are transferred to the pumps.
On the pipeline, if...
Good day,
I am currently designing a steel pump-line(500mm dia.) The pipeline exits the pump station and surfaces after about 20m. From there it runs above ground for approximately 1500m. The first section of pipline (before it goes underneath a road) is approx 100m. The thermal expansion on...
