Rotary Vane Vacuum Pump and Liquid Ring Vacuum Pump are two common types of vacuum pumps. They have some differences in terms of working principle, application fields, advantages and disadvantages, etc.
How to choose the vacuum pump used in the laboratory is a problem that plagues many users. After buying a vacuum pump, many users will encounter the vacuum gauge to observe that the vacuum is not enough (not enough suction), the pumping speed is too slow, and it is used in a relatively closed room. Excessive noise, or oil mist when the pump is in use, can not be used normally, and other problems. These problems are often related to the selection.
Large circulating water vacuum pumps are used in many industrial sectors such as petroleum, chemical, machinery, light industry, medicine and food. Circulating water vacuum pumps are widely used in many processes of industrial production, such as vacuum filtration, vacuum water diversion, vacuum feeding, vacuum evaporation, vacuum concentration, vacuum regain and vacuum degassing. The use of large circulating water vacuum pumps should not neglect some details. Pay attention to the following when using:
