Inlet pressure, rotational speed, air intake volume
Thread Content
Hello, everyone. Liquid ring vacuum pump. The suction pressure is absolute pressure, ranging from 0 to 1013 mbar. At a constant suction pressure, increasing the rotational speed increases the amount of air drawn in. At a constant speed, when the suction pressure increases to 180–280 mbar, the suction volume remains high; thereafter, as the suction pressure continues to rise, the suction volume decreases until it stabilizes. What causes this?
When the inlet pressure is low, the volume of air flowing in decreases; in other words, less air enters, so less air is drawn in
1. The ultimate vacuum level of a water ring vacuum pump is 33 mbar. 2. It is common knowledge that the higher the vacuum level, the lower the pumping capacity. 3. When selecting a vacuum pump, choosing one with insufficient capacity is an error
You’re welcome; I hope this can help you:victory:
