发明名称 Liquid Ring Vacuum Pump with Cavitation Regulation
摘要 A method for operating a liquid ring vacuum pump employs taking vibration measurements of the pump and comparing the measurements with a prescribed cavitation threshold. In addition, a measurement representing the liquid content in the gas to be conveyed is taken. This measurement is compared with a prescribed threshold. The rotational speed of the liquid ring vacuum pump is reduced if the prescribed cavitation threshold has been exceeded and the liquid content is less than the prescribed threshold. The rotational speed is increased if the prescribed cavitation threshold has been exceeded and the liquid content is greater than the prescribed threshold. A liquid ring vacuum pump is designed for implementing the method. Due to the regulation depending on the oscillations of the pump, the pump can be operated near the cavitation boundary without any risk of damage.

主权项 1. A method for operating a liquid ring vacuum pump having a rotational speed for delivering a gas with a liquid content having the following steps: a. recording measured vibration values of the pump and comparing the measured vibration values with a predefined cavitation threshold value; b. recording a measured value which represents the liquid content in the gas to be delivered, and comparing the measured value with a predefined limiting value; c. adapting the rotational speed of the liquid ring vacuum pump, i. the rotational speed being reduced if the predefined cavitation threshold value has been exceeded and the liquid content lies below the predefined limiting value;ii. the rotational speed being increased if the predefined cavitation threshold value has been exceeded and the liquid content lies above the predefined limiting value.
