Impact of the water ring vacuum pump opening degree
Thread Content
Does the opening degree of the exhaust port in a water ring vacuum pump affect the water ring? It has been recently observed that when the exhaust vents are fully open, more overflow occurs from the overflow port of the vapor-liquid separator (which supplies water for the vacuum pump to operate) ； When the exhaust port is closed a bit, less overflow occurs. (The overflow port of the vapor-liquid separator is roughly parallel to the midpoint of the pump chamber.)
When the valve is fully open, more air is drawn in, and more air is expelled as well; more water vapor is carried away with it. In the separation tank, this water vapor condenses into water, resulting in an increased amount of overflow
