Main industrial vacuum types
Vaccum is the basic utility that is used in a vast process in the manufacturing processes of industries such as bottling, packaging, degassing, drying, pick and place, and a lot more. The use of the vacuum pump Singapore is to create, maintain, and improve the vacuum for these processes. There are in existence several types of vacuum pumps currently and you should choose according to your needs.
So it is important to understand the benefits, features, and operating principles of multiple types of vacuum pumps. Here we bring to you different types of vacuum pumps.
Different types of vacuum pumps:
- Gas transfer pumps: in these pumps gas molecules are transferred using the technique of positive displacement or momentum exchange i.e. kinetic exchange. The number of gas molecules that get discharged from the pump is the same as the number that enters it. When expelled the gas is somewhat above the atmospheric pressure. The compression ratio, in this case, is the ratio of the outlet i.e. exhaust pressure to the inlet i.e. lowest pressure that is obtained.
- Kinetic vacuum pumps: these pumps make use of high-speed blades or vapor which is introduced to direct the gas towards the exit. It makes use of the momentum transfer principle. In these pumps, high compression ratios can be achieved at low pressures but they do not contain sealed volumes.
- Positive displacement pumps: these pumps work by trapping mechanically the volume of gas and moves it inside the pump. These are designed in different stages on a shaft of a single drive type. The isolated volume of vacuum gas is compressed to a little volume using high pressure and then the gas that is compressed is expelled to the next pump or in the atmosphere. To achieve a high vacuum and more flow rate multiple or 2 transfer pumps are used in conjunction.
- Entrapment vacuum pumps: these pumps capture gas molecules on their surface within the system of the vacuum pump and are therefore known as entrapment of capture pumps. The vacuum pumps in Singapore operate at low flow rates as compared to other vacuum pumps like transfer pumps but they can give quite a high vacuum somewhat around 10-12 Torr. Capture pumps work using ionic reaction, cryogenic condensation, or chemical reaction. there are no moving parts in the vacuum pump and so you can obtain an oil-free vacuum.
The entrapment pumps that are designed to work with chemical reactions usually are more effective as they are placed in a container where there is a need for a vaccuum. Air molecules make a thin film that is removed when the pump causes a chemical reaction on the internal area of the pump.
