Water ring vacuum pump will generate the cavitation when worked under limited vacuum which can cause equipment damage, lower reliability.
The vacuum system unit suction ability is insufficient when it’s running. Air ejector, also called air jet vacuum pump, it takes the pressure difference between ejector and liquid ring pump to produce air jet. The vacuum inside of the ejector could be lower than the vacuum pump for suction pressure.
The air ejector liquid ring vacuum system improves the ultimate vacuum of the vacuum pump, prevents the liquid ring vacuum pump cavitation, eliminate noise and vibration(protect the vacuum pump), which make the main system works safely during the operation at the same time.
Such as power plant main body of electricity generator.
