A vacuum pump works by creating a pressure difference between the volume to be processed and the environment. Main stages of operation:<\/p>

  1. Gas capture:<\/strong>
    The gas from the volume enters the working chamber of the pump.<\/li>\n\n
  2. Compression:<\/strong>
    In the working chamber, the gas is compressed by mechanical or physical action.<\/li>\n\n
  3. Deletion:<\/strong>
    The compressed gas is discharged from the working chamber into the atmosphere or a special collection vessel.<\/li><\/ol>

    Types of vacuum pumps differ in the way they create a vacuum:<\/p>

    • Mechanical pumps:<\/strong>
      Vacuum is created by moving parts such as pistons, plates or a rotor.<\/li>\n\n
    • Diffusion pumps:<\/strong>
      A stream of oil or mercury vapour is used to create a deep vacuum.<\/li>\n\n
    • Turbomolecular pumps:<\/strong>
      They create a vacuum due to the high-speed rotation of the blades.<\/li>\n\n
    • Cryopumps:<\/strong>
      Low temperatures are used to condense gases and vapours.<\/li><\/ul>

      Areas of application<\/strong><\/h3>
      1. Pharmaceuticals:<\/strong>
        • They are used in the processes of drying, degassing, and the production of sterile preparations.<\/li><\/ul><\/li>\n\n
        • Chemical industry:<\/strong>
          • Creating vacuum in reaction systems, purifying gases, evaporating solvents.<\/li><\/ul><\/li>\n\n
          • Metallurgy:<\/strong>
            • They are used for vacuum casting, heat treatment and brazing of metals.<\/li><\/ul><\/li>\n\n
            • Food industry:<\/strong>
              • Vacuum packaging of food, removing air from food products such as sauces or juices.<\/li><\/ul><\/li>\n\n
              • Scientific research:<\/strong>
                • Physical and chemical experimentation facilities, vacuum chambers for evaporation or coating.<\/li><\/ul><\/li>\n\n
                • Electronics:<\/strong>
                  • Production of semiconductors, vacuum sputtering of films.<\/li><\/ul><\/li><\/ol>

                    Features of vacuum pumps<\/strong><\/h3>
                    1. Types of vacuum:<\/strong>
                      • Rough vacuum:<\/strong> Corresponds to low vacuum levels (1-1000 mbar).<\/li>\n\n
                      • Medium vacuum:<\/strong> The pressure is within 10-\u00b3-1 mbar.<\/li>\n\n
                      • Deep vacuum:<\/strong> Pressure below 10-\u00b3 mbar, used for specialised applications.<\/li><\/ul><\/li>\n\n
                      • Resistance to aggressive environments:<\/strong>
                        Special models can handle aggressive gases or vapours.<\/li>\n\n
                      • Pumping speed:<\/strong>
                        Determines how much gas the pump can remove per unit of time.<\/li>\n\n
                      • Energy efficiency:<\/strong>
                        Modern models are equipped with economical engines, which reduces energy consumption.<\/li>\n\n
                      • Compactness:<\/strong>
                        Some pumps have a modular design that allows them to be integrated into compact systems.<\/li>\n\n
                      • Noise and vibration:<\/strong>
                        The low-noise models are suitable for laboratory or medical applications.<\/li><\/ol>

                        How do I choose the right vacuum pump?<\/strong><\/h3>
                        1. Vacuum level:<\/strong>
                          Determine which vacuum level is required for your process (rough, medium or deep vacuum).<\/li>\n\n
                        2. Productivity:<\/strong>
                          Consider the volume of the system to be pumped and the pumping speed.<\/li>\n\n
                        3. Type of environment:<\/strong>
                          Make sure that the pump is suitable for your type of gas or vapour (corrosive, toxic, abrasive).<\/li>\n\n
                        4. Materials:<\/strong>
                          For use with aggressive substances, choose models made of stainless steel, Teflon or other chemically resistant materials.<\/li>\n\n
                        5. Operating conditions:<\/strong>
                          Consider the temperature, humidity and frequency of use of the pump.<\/li>\n\n
                        6. Protection system:<\/strong>
                          Choose a pump with protection against overheating, dry running and mechanical wear.<\/li><\/ol>
