Large or Small Vacuum Pump ? What Are The Differences ？

There are many types of vacuum pumps : dry screw pumps, rotary vane pumps, roots pumps, water ring pumps, vortex pumps, claw pumps, etc. and vacuum pumps are widely used in industries such as metallurgy, chemical industry, food, semiconductors, electronic power, etc.

A vacuum pump is a device that pumps air from a pumped container under the action of force to maintain a vacuum. Vacuum pumps are commonly used in vacuum equipment, cryogenic equipment, papermaking machinery, petroleum, mining, foundation treatment and other fields. Different vacuum pumps have different working principles and uses.

Advabtages of large vacuum pumps : Large industrial vacuum pumps have high power and high pumping speed, and the vacuum they produce is very close to the theoretical vacuum. Large industrial vacuum pumps are widely used in many fields, such as semiconductor production, solar energy, optics, pharmaceuticals and food industries.

Disadvantages of large vacuum pumps : high price, large size, heavy weight, high noise, high energy consumption, regular maintenance required, difficult to move, etc. Some large vacuum pumps must use vacuum pump oil or lubricating oil, which will produce oil mist during work and pollute the working medium... etc.

Advantages of small vacuum pumps : rough vacuum, small in size, low in noise, low in power consumption, easy to operate, easy to carry, maintenance-free, can operate continuously for 24 hours, and allows the medium to be rich in water vapor. Most importantly, there are dry and oil-free distinctions, no vacuum pump oil or lubricating oil is required, no pollution, no interference with the analysis of the medium, etc., and the price is relatively much cheaper, etc.

With the widespread application of vacuum, many types of vacuum pumps have been developed, and their pumping speeds range from a few tenths of a liter per second to hundreds of thousands or millions of liters per second. As the requirements for the application pressure range of vacuum technology in the fields of production and scientific research become wider and wider, most of them need to be composed of several vacuum pumps to form a vacuum pumping system to jointly pump air to meet the requirements of production and scientific research processes. Since the range of working pressures involved in vacuum application departments is very wide, any type of vacuum pump cannot be fully applicable to all working pressure ranges. Different types of vacuum pumps can only be used according to different working pressure ranges and different working requirements. For the convenience of use and the needs of various vacuum processes, various vacuum pumps are sometimes combined according to their performance requirements and applied in unit form.
