Stamping issue of the outlet buffer tank of the high-pressure coal slurry pump
Thread Content
What is the pressure level in the buffer tank at the outlet of high-pressure coal slurry pumps? Experts, please share the pressure values of the buffer tanks used in your companies for such pumps. What effects does a higher or lower pressure in the buffer tank have on the pump? What specific impacts does it have on the pump’s outlet flow rate and pressure?

It is usually 75% of the work-related stress; either high or low levels of stress fail to provide any buffering effect, and they can also cause fluctuations in the slurry flow rate, as well as affecting the diaphragms of the burners and pump valves.
70–90% of the actual operating pressure; when the pressure is higher than this value, the accumulator is unable to effectively absorb the pulses at the pump outlet, and thus it cannot play a role in balancing the pressure or stabilizing the flow rate. It has little impact on the pump itself.
I’ve seen information stating that the pressure can reach over 60 kilograms (while the furnace is designed for 40 kilograms). Considering our actual conditions, if we apply 60% of the designed pressure, the entire coal slurry pipeline shakes violently. When the pressure is raised slightly above the outlet pressure, the vibration disappears and the flow rate remains stable. Perhaps the practical one is the best.
First, the reserve pressure of the diaphragm pump must be able to exceed the pump inlet pressure. Secondly, this pressure value is generally 60% to 90% of the normal pressure at the pump outlet. I’m not sure if what I said is correct.
It is generally necessary to keep it at around 80% of the operating pressure in order to achieve a buffering effect.
60 percent of the actual pressure at the pump’s outlet is sufficient. Low pressure fails to provide cushioning, while pressure higher than the operating pressure serves no purpose. Our unit uses GEHO
Flouret recommends 70%-90% for stamping
80% of the normal operating pressure; values that are too low or too high will have a significant impact. If the outlet pressure is 100% of the operating pressure, then no buffering effect will be achieved at all.
The plunger pump operates cyclically, and its outlet pressure is actually stabilized by the buffer tank. The so-called 80% and 90% may seem quantitative, but in reality they are vague ； The pressure in the actual buffer tank is generally still similar to the pump outlet pressure. From the moment material is fed in until pressure increases, the pump outlet pressure keeps changing; at such times, it’s not possible to expect the buffer tank pressure to change as well, right? The outlet pressure of the pump should be in balance with the tension of the diaphragm and the pressure in the buffer tank; when the outlet pressure is similar to the pressure in the buffer tank, the diaphragm experiences little variation, resulting in minimal fluctuations in the slurry flow rate and stable flow.
