In this case, however, a multiple limiting factor is the hydraulic fluid which is used as pressure transfer fluid from the piston to the diaphragm.

  • common salts for example sodium chloride, they have a lower melting point and can be liquid even at room temperature.
  • all salts which are liquid in pure form below 100 ° C. are considered to be ionic liquids.
  • Ionic liquids can be referred to as liquid salts. They have an extremely low vapor pressure (10 "13 bars), have only small gas solubility, are non-flammable, are often physiologically harmless, are often thermally stable up to 250 0 C and lubricity. The list of advantages that ionic liquids , is long, so ionic liquids make one umweit- and resource-saving replacement for the previously described fluids.

  • the clever use of these extraordinary properties of ionic liquids is the key to the successful use of these fluids in the sense of the invention.
  • Ionic liquids are therefore able to avoid the disadvantages described so far. Due to their extremely low vapor pressure of 10 "13 bar (liquid salt), they can achieve extremely low pressures in the vacuum technology and at the same time avoid contamination of the process gas in both vacuum pumps and compressors.
  • ionic liquids in process machines, it is now also possible to operate the aforementioned piston machines with a liquid piston, which consists of an ionic liquid, while avoiding the disadvantages described.
  • the use of ionic liquids also has the advantage that a reaction with the conveyed is excluded because they are highly inert.
  • liquid ring vacuum pumps due to the use according to the invention of ionic liquids as ring liquid, the use of these pumps is also made possible in the fine vacuum range.
  • liquid ring vacuum pumps can be used instead of the previously used screw compressors, reciprocating compressors, rotating vane compressors, etc. be able to fully exploit their great advantages in terms of robustness, reliability and process reliability.
  • a paddle wheel is eccentrically arranged in a cylindrical housing in a liquid ring vacuum pump.
  • the operating fluid in the housing forms due to the rotation of the impeller a co-rotating, concentric liquid ring. This completes together with the rotor blades, the gas volumes in the chambers. Due to the eccentricity of the rotor, the blades in the upper area completely submerge in the liquid ring, so that the chamber volume is filled with operating fluid.
  • the liquid ring lifts off the impeller hub and forms a crescent-shaped space.
  • the gaseous fluid to be delivered is sucked into the working space by the control disk openings arranged on the end faces of the impeller.
  • the suction slot ends, and the chamber is sealed by the control discs, the impeller blades, and the fluid. Then the liquid ring migrates back to the hub and compresses the gas like a piston. As soon as the pressure slot openings are reached, the compressed gas is expelled.
  • the operating fluid has to fulfill in liquid ring vacuum pumps above all three functions, namely, first, the function of a moving piston with the Working cycles sucking, compressing and pushing out, secondly the sealing function for sealing the pump chambers against each other and thirdly the absorption of the heat of compression.
  • a portion of the operating fluid is constantly discharged through the pressure slot, wherein the same amount of fresh liquid is supplied via a fluid channel in the shaft hub of the pump. Due to this permanent recooling, a constant temperature of the operating fluid is achieved.
  • the vapor pressure of the working fluid limits the lowest suction level to be achieved in the intake manifold of the pump. If the suction pressure drops to a value equal to or close to the vapor pressure of the liquid, it cavitates and thus a complete power loss of the pump.

  • oils lead to contamination of the pumped medium and pose an environmental risk.
  • chemicals for example, concentrated sulfuric acid for chlorine gas compression.
  • the invention provides a remedy by extending the range of application of the liquid ring vacuum pumps in the fine vacuum range due to the inventively provided use of ionic liquids. Since such ionic fluids have no appreciable vapor pressure, no cavitation occurs, so that there is no limitation of the suction pressure down. Furthermore, ionic fluids have very good lubricating properties and thus enable a shaft seal adapted to the fine vacuum. In contrast to the use of oil, there is no contamination of the delivery fluid.
  • Liquid ring vacuum pumps Due to the inventively provided use of ionic liquids in process machines, in particular in liquid ring vacuum pumps, therefore their range of application is expanded into the fine vacuum range. Liquid ring vacuum pumps are thus entering a field of application previously covered by rotary and gate valves, Roots pumps or steam jet pumps.
