Rotary Screw Air Compressors: Under the Hood

Nowadays, people can find compressed air all around: in factories and homes across the globe, serving various industries. With ample compressed air, it is no surprise to find different compressor types. So, when looking for an ideal rotary screw air compressor, it is vital to know how they work and the several types available. 

Let's take a closer look at the technology of rotary screw air compressors!

What Is a Screw Compressor?

The screw element was created in the 1930s. It has two distinct parts, a female and a male rotor. In oil-injected screw compressors, the male rotor powers the female rotor. While in oil-free compressors, a timing gear is responsible for driving both rotors. The rotors toil together smoothly with very minimum space between them.

What Are the Impressive Benefits of a Rotary Screw Compressor?

Are you planning to invest in a rotary screw air compressor? That's great. Let's have a glance at some of the important benefits you can expect:

  • Zero loss of property over time
  • Higher reliability
  • Low oil carryover (as little as 3 ppm) in an oil-lubricated machine
  • Energy efficiency
  • Continuous operating capability even at high temperatures of up to 46°C
  • 100% duty cycle
  • Small footprint
  • Low noise levels

What Is the Primary Working Principle of a Screw Compressor?

As mentioned earlier, a screw compressor works with a male and female rotor that rotates in the opposite direction. This movement brings in air that is compressed as the space between the rotors and their housing decreases gradually. The compressed air then gets displaced directly to the outlet.

It has already been stated that the rotor elements are driven by the male rotor or by a timing gear. In an oil-injected screw compressor, the former drives the female rotor while in oil-free compressor technology, the timing gear plays the role to drive both rotors for harmonic running with minimum calculated clearance between both elements.

Each screw element has a static, built-in pressure ratio dependent on the pitch and length of the screw. To get maximum efficiency, the built-in pressure ratio must be adapted and adjusted to the necessary work pressure.

However, the speed of the rotors is optimised at a definite level to reduce mechanical losses, due to heat at a very high speed and volumetric losses, due to air loss at a very low speed.

Areas to Witness the Use of Rotary Screw Compressor:

Today, screw compressors are available almost everywhere as most industries are focusing on the use of compressed air. Thanks to their useful benefits that makes them the top choice for many industries. Here are some of the industries that make use of them:

  • Transportation
  • Construction
  • Food and beverage
  • Textile
  • Medicine and Health
  • Mining

Rotary Screw Compressors: The Powerhouse that Keeps Your Business Running

One of the compelling reasons for the massive popularity of rotary compressors is their versatility. The reality is that the right rotary compressors can serve every application. Masteraire offers outstanding screw compressors with three types of drives, having its own perks.

Belt Drive

These compressors are extremely sturdy as well as easy to install and maintain. Plus, the initial investment cost in this regard is the lowest compared to other rotary screw compressors. This makes them the best fit for smaller operations.

Direct Drive

This is the optimum of the entire rotary technology. The exclusive direct drive offers exemplary performance and efficiency. Among all, they are popular for their noise-free features. Additionally, direct-drive rotary screw compressors come in numerous types- from a basic design for the smaller models to those with ultra-efficient variable speed drives.

Gear Drive

A gear Drive makes the air compressor quieter. Although the investment involved is higher than the belt drive, it can also promote greater energy efficiency. Hence, if you need to use the compressor a lot, this investment will definitely pay off over time. Thanks to its energy-saving features.
