A vacuum pump is a device used in a variety of ways to create, improve and maintain a vacuum in an enclosed space.

The device is a multifunctional tool with many research and scientific applications. Some of the most common uses include:

Vacuum pumping:

Through the change of the volume of the pump chamber, the process of inhalation and exhaust is completed. The negative pressure achieved after pumping is used to promote the volatilization of water into water vapor, and then the water is sucked away from the air conditioner by the powerful suction of the vacuum pump, so as to achieve the purpose of extracting the water in the air conditioner.

Drying:

The vacuum pump removes water from the container, which helps prepare it for further sterilization.

To realize the water cycle:

The vacuum pump is not only a vacuum pumping device, but also can provide circulating cooling water to the reaction plant. The water used should be kept free of impurities. Too high water temperature will affect the performance of the water ring vacuum pump, such as vacuum degree and pumping capacity.

Vacuum is probably the most critical consideration, as it affects every other factor.

Factors to consider before buying:

Maximum flow rate (lpm) is the fastest rate at which steam can be expelled through a vacuum. At atmospheric pressure, a pump with a maximum flow rate of 10 litres per minute (lpm) is capable of pumping 10 cubic metres of steam per minute. It is also known as pumping speed.

Maximum vacuum (mbar) is the minimum pressure level of vacuum. Pumps operating at ambient temperatures with a maximum vacuum of 0.1 mbar can evaporate gases with vapor pressures greater than 0.1 mbar.

In addition, the following factors should be considered: net weight (Kg), horsepower (hp), speed, hose barb (mm), noise decibel level (dB), etc.
