However, reciprocating compressors are more flexible when working in changing pressure conditions. For instance, multi-stage systems require more maintenance. While this can be beneficial in many applications, it also exposes the compressor unit to various problems. Reciprocating air compressors operate on a multi-stage mechanism. The pressure ratio in a centrifugal air compressor is also lower than in reciprocating compressors. This means that reciprocating compressors can handle as much air volume as centrifugal compressors.Ĭentrifugal air compressors are more efficient in low pressure and high discharge operations since they operate at a constant flow rate. For instance, reciprocating compressors operate on pulsating air at a high-pressure ratio. They are also more affordable.Ĭonsidering operational efficiency, these compressor types are different in terms of volume and pressure features. On the other hand, reciprocating compressors are more efficient than centrifugal compressors when the pressure ratio is above two. Additionally, centrifugal compressors are low maintenance than reciprocating compressors. These compressor units are also more superior when it comes to isentropic efficiency. Here are the central differences between these two compressor types.Ĭentrifugal air compressors have relatively better isothermal efficiency than reciprocating compressors. Operational and efficiency distinctions are essential in determining the differences between centrifugal and reciprocating compressors. What Is The Difference Between Centrifugal And Reciprocating Compressors?
After the air is injected into the compressor cylinders, reciprocating motions of the pistons compress it. The pistons draw back to allow air into the intake valve and the compressor unit. The pistons are central to the compressor function. The compressor unit also has a design that looks like an internal combustion engine. What Is A Reciprocating Compressor? A reciprocating air compressor uses pistons to compress air. The kinetic energy is converted into pressure as the air passes through the diffuser and volute.Ĭentrifugal air compressors are used in almost every industry due to their reliability and efficiency. The process results in a high-pressure build-up and kinetic energy. The air is then pushed to the center of the impeller by centrifugal force.
This means that centrifugal air compressor performance depends on the inlet temperature and different external factors.Ĭentrifugal air compressors work by sucking air into the core. Centrifugal compressor configuration works at constant pressure. What Is A Centrifugal Air Compressor?Ī centrifugal air compressor is also known as a dynamic compressor with a radial design. This article focuses on the differences between centrifugal and reciprocating compressors. When determining the compressor type that works for you, you may want to consider the following four components: However, the two most common variations are centrifugal and reciprocating compressors. You may want to look into aspects such as operating conditions, application requirements, and optimal uses.Īccordingly, there are many compressor options. There are many differences to consider when choosing between a centrifugal air compressor and reciprocating compressors. What Are The Advantages And Disadvantages Of Centrifugal Compressors Over Reciprocating Compressors?
