The rotary vane vacuum pump is an oil-sealed mechanical pump that achieves gas extraction by utilizing a rotor to drive vanes in an eccentric rotation, thereby altering the volume of the pump chamber. It is widely employed as a backing pump and for providing low-vacuum environments in scientific research and industrial settings.
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.
The cryogenic coolant circulation pump adopts a cryogenic liquid circulation device that is mechanically cooled. It has the function of providing a cryogenic liquid and a low temperature water bath. Combined with rotary evaporator, vacuum freeze drying oven, circulating water vacuum pump, magnetic stirrer and other instruments, the chemical reaction operation and drug storage under multi-functional low temperature are carried out. It has the functions of providing low temperature constant temperature liquid bath, low temperature constant temperature condensation cooling, low temperature constant temperature storage, establishing a second low temperature constant temperature field, etc., and is widely used in medicine, chemical industry, scientific research experiments and the like.
