What Are Rotary Screw Compressors?
Screw compressors are a specialized type of compressor that uses a rotary-type positive-displacement mechanism. These compressors are typically used to replace piston compressors due to a screw compressor’s ability to create large volumes of high-pressure air. They work efficiently for larger industrial purposes or for operating high-power air tools, such as grinders and impact wrenches. Screw compressors can run 24/7, 365 days a year without any problems. Due to their rotors’ continuous sweeping motion, screw compressors deliver minimal pulsation or surging of airflow. This makes screw compressors capable of producing fewer vibrations or sounds. When you require constant demand for air, screw compressors are the way to go.
How Screw Compressors Work: Two Rotors to Compress Air
The basic principle of screw compressors is that they have two rotors (helical screws) to compress air. These two rotors are described as “male” and “female,” and fit together like a puzzle piece despite being two different shapes. When the two rotors begin rotating in opposite directions, the air is drawn in and “trapped” between the male and female parts. Since the rotors are continuously spinning, the air is forced to one side (the “pressure side”) where new air is sucked in.
There are two types of screw compressors available. Though the outcome is the same for both machines, they are designed quite differently when it comes to the part where the actual compression takes place. These two types are:
Oil-Injected
This version is the most commonly used screw compressor and requires oil to operate correctly. 99.9% of the oil remains inside the compressor, though there will always be a little oil that is carried over to the compressed air during operation. As a result, this type of screw compressor is unable to produce oil-free air, which typically isn’t an issue unless you require oil-free air.
Oil-Free
This screw compressor delivers pure air. Since this air compressor is oil-free, it cannot cool the compressed air, elements, and rotors with oil. Oil-free screw compressors have two compression elements that work to cool and further compress the required air. The stages are designed to work in perfect harmony with one another.
Screw compressors usually do not contain valves and do not contain any sort of mechanical force that would cause an imbalance. This makes them capable of working at high speeds combined with significant flow rates that can all be confined within a very small exterior. Screw compressors are the most widely used air compressor model and tote very low-energy consumption rates.
Choosing the Right Speed Drive for Your Screw Compressor
There are speed drive options for your screw compressor: fixed speed drive and variable speed drive. To break it down, a fixed speed drive delivers consistent frequency and voltage to the motor. This means that when air demand is lower, the efficiency is also lower due to the frequency and voltage that is not being used to full capacity. Fixed speed drive screw compressors are useful if you require constant airflow. On the other hand, variable speed drive fluctuates the frequency and voltage supplied to the electric motor. This allows the speed of the motor to be efficiently controlled with the demand for air at any given point in time. Variable speed drive screw compressors work to minimize energy consumption by automatically adjusting speed to match air demand.
