Energy-saving effects of hydrogenated hydraulic turbines, payback period, operation cycle, and selection
Thread Content
I am eagerly hoping that experts can introduce me to the energy-saving efficiency of hydrogenated high-pressure hydraulic turbines as well as the manufacturers of such turbines, so that we can share our experience in using them: handshake
It is recommended to use Flowserve turbines. The main issue with these turbines is that they handle media at high temperatures and pressures, containing hydrogen sulfide gas; moreover, the mechanical seals have a limited lifespan. Additionally, since the components used are from the domestic Sichuan Ri Ji company, they often need to be replaced.
I consulted some research institutions regarding the payback period for hydraulic turbines. Generally, the higher the pressure, the shorter the payback period; it is around 5 years for pressures above 10.0 MPa, while for medium-pressure hydrogenation at 8.0 MPa, the payback period is around 10 years or more. But no research has been done; this is for reference only.
I am eagerly hoping that experts can introduce me to the energy-saving efficiency of hydrogen-powered high-pressure hydraulic turbines as well as the manufacturers of such turbines, so that we can share our usage experiences. We use those made by Shin-Nippon; they are okay, but due to design reasons, their rated power is on the high side.
This one was made by Kalite Ebara Pump Co., Ltd.; it’s currently in the ordering process
Ours is also Japanese-made, but it’s okay
It was appointed by Jalit, and we are also in communication regarding this. According to the information provided by Jalit, the payback period is approximately 1 year.
We use models made by New Japan Machinery; their quality is acceptable and they operate smoothly. However, once the machine seals were replaced with domestic ones, leaks started to occur frequently.
