What is the Rotary Compressor?

A rotary compressor is a type of positive displacement compressor that utilizes rotating components to compress air or gas. It comprises a rotor mounted on a shaft within a stationary casing or housing. The rotor possesses one or more lobes or blades that trap the air or gas between them and the housing during rotation. This trapping mechanism reduces the volume of the air or gas, thereby increasing its pressure. Rotary screw compressors, a subset of rotary compressors, employ two meshing helical screws, or rotors, to compress air. The rotors’ interlocking spirals turn, pushing air through chambers and compressing it into a smaller space. Continuously created compressed air is then stored in a receiver tank for later use. While the core design principle of using two meshing rotors for air compression has remained consistent since its inception in the mid-1900s, improvements in manufacturing and materials have made these compressors more efficient and durable. Incorporating electronic controls and automation has also streamlined their management and maintenance processes. Additionally, some modern rotary screw compressors come equipped with variable speed drives to modulate airflow according to demand, leading to energy conservation.

How Does A Rotary Compressor Work?

The functionality of a rotary compressor hinges on its ability to reduce the volume of gas or air, thereby increasing its pressure through a series of smartly designed steps. Firstly, one or more rotors, mounted on a shaft and equipped with lobes or blades, trap gas or air between them and the housing as they rotate. This trapping action takes place in a compression chamber, whose volume decreases with the rotors’ rotation. The gas or air enters via an inlet port, located centrally or laterally in the housing, and is then compressed as the rotors continue their rotation. Lubrication, often in the form of oil, is crucial for cooling and sealing between the rotors and the housing, and for reducing friction and wear. Once the gas or air reaches the desired pressure, it is discharged through a port at the housing’s outer edge. Control systems, including variable speed drives and sensors, regulate the compressor’s operation for optimal performance, allowing precise control over speed, pressure, and temperature. This methodical approach ensures that rotary compressors can efficiently provide compressed gas or air for various applications.

What are the Structures of A Scroll Compressor?

A rotary compressor’s structural organization involves three primary moving parts: a blade, a roller, and another roller placed eccentrically, enclosed within a sealed chamber. Together, these parts transform low-pressure gas into high-pressure gas. Beyond these core components, the compressor features a body that houses both the motor in the electrical section and the compressor mechanism in the mechanical section, alongside a cylindrical accumulator. The compressor’s operation centers around rotating components, termed rotors, which come in different shapes such as screws or scrolls, depending on the type. They are situated on a shaft inside a housing, where they compress gas or air in the reducing space of the compression chamber. The compressor may also integrate a lubrication system for minimizing friction, a drive system for powering the rotors, control systems for performance regulation, and cooling systems for temperature management, with variations according to the compressor’s intended use and power requirements to ensure optimal compression efficiency.

What are the Main Types of A Rotary Compressor?

Different types of rotary compressors serve diverse applications based on specific requirements. Here are the primary types:

Lobe Compressors: Characterized by two spinning wheels with small pockets, lobe compressors draw air into chambers where it gets compressed upon moving to the opposite side. Nevertheless, this type of compressor may not be suitable for applications requiring heavy duty continuous airflow and high pressures.

Vane Compressors: Vane-type compressors have offset vanes inside the chamber. As air enters, it’s moved by rotating vanes to a narrower part of the chamber, getting compressed with little effort. These compressors are user-friendly but prone to vane wear over time, necessitating replacements to maintain efficiency.

Scroll Compressors: With two scrolls and spirals, one stationary and the other orbiting, scroll compressors pull air along the edge into tight spiral circles before expelling it through the center outlet. Ideal for intermittent tasks in confined spaces, scroll compressors offer efficiency in a smaller package compared to screw compressors.

Screw Compressors: Highly reliable and popular, screw compressors work with two intermeshed screw rotors with helical lobes that draw in and compress air. They are frequently used in applications needing high flow rates and moderate pressures, with the 4/6 lobe combination in the rotor design being especially efficient.
