Vacuum pump is a device that draws air or gas through a vacuum system. This equipment, which is frequently used in industrial applications, is also needed in the laboratory environment. Although it is known most of the time, very limited information is available about it. At this point, it would be useful to learn comprehensively what it is, what it does, its working principle and areas of use. You can continue reading the content to get detailed information about the vacuum pump.

What is a Vacuum Pump?

A vacuum pump is a device that removes gas molecules from a closed unit by a vacuum system. It lifts these molecules using negative or low pressure. It serves specific applications in industrial, medical or food fields. There are many types according to vacuum levels and are preferred according to their usage areas.

Working Principle of Vacuum Pump

The working principle of the vacuum pump exists in two different ways. These are known as gas retention and gas transfer. The device, which works with gas transfer, facilitates the movement of molecules and creates a vacuum. On the other hand, it creates a vacuum by keeping the molecules frozen in the principle of gas retention.

What are the Types of Vacuum Pumps?

Vacuum pumps are divided into many types and have different technological equipment. May be exposed to gas, water or oil in pump operation. At this point, devices designed as wet or dry type come into play. Generally, dry vacuum pumps, oiled vacuum pumps and water-based vacuum pumps are used in industrial applications. Dry vacuum pumps are one of the traditional devices. This device does not produce any waste and requires less maintenance. It consists of important components such as diaphragm, turbo molecular pump, scroll and piston. It provides a clean vacuum process and may be more costly than others.

Oil-filled vacuum pumps are preferred in industrial applications because they have high capacity. They provide high efficiency in proportion to these features. They are more economical than others, but they require a filter. However, they require an oil change. Depending on these requirements, oil-filled vacuum pumps prevent damage to the environment. Since it also has input and output filters, it has different hardware features compared to others.

Water-based vacuum pumps, on the contrary to dry vacuum pumps, are designed for situations where liquid is exposed. It is also lower cost and has fewer maintenance requirements. They are resistant to corrosion due to their structural features. They carry out the cleaning process alone by throwing away the dirty water.

Where is Vacuum Pump Used?

Vacuum pump is used in many areas depending on its preferred types. These devices, which have the task of transporting gas molecules by vacuuming, are most useful in industrial applications. Usage areas of vacuum pumps can be listed as follows:

● In drying applications in the textile industry

● In hard layer coating processes in the automotive industry

● In applications requiring high vacuum

● In medical fields

● In cases where unwanted gas or vapor needs to be removed in the chemical industry

● In vacuum application and gas pressing processes in the manufacturing industry

What Does a Vacuum Pump Do?

It is possible to give comprehensive answers to the questions of what a vacuum pump is and what it does. Because this special device enables many applications to be carried out efficiently with its design and functional features. It should be noted that the areas where it is most useful are laboratories and industrial places. The benefits of the vacuum pump are:

● Provides filtration and aspiration of liquid samples.

● Collects gas samples from the atmosphere.

● It reduces vapor pressure and helps control solvent pressure.

● Provides negative pressure to trap hazardous sample materials.

The vacuum pump is very useful because it is an effective device. It vacuums more gas molecules than air in a closed environment. In all these aspects, it is used in areas such as chemistry, medical, industrial and food.
