Applications of Two Stage Screw Compressors

Introduction

Two stage screw compressors are a type of compressor that is widely used in various industries due to their high efficiency and reliability. In this article, we will explore the applications of two stage screw compressors in different industries, their advantages over other types of compressors, and the factors to consider when choosing them. We will also discuss the basic principles of two stage screw compressors, their components, and how they work.

Definition of Two Stage Screw Compressors

Two stage screw compressors are a type of compressor that uses two rotors to compress gas. The rotors are usually helical in shape and rotate in opposite directions. As the rotors turn, the gas is drawn into the compressor and compressed between the rotors. The compressed gas is then discharged through an outlet.

Brief History of Two Stage Screw Compressors

The first screw compressor was invented by Swedish engineer, Alf Lysholm, in 1935. Since then, the design has been improved and modified to suit different applications. Two stage screw compressors were developed to provide higher compression ratios and better efficiency.

Importance of Two Stage Screw Compressors in Various Industries

Two stage screw compressors are used in various industries such as oil and gas, chemical, food and beverage, pharmaceutical, and manufacturing. They are used to compress gases such as air, nitrogen, hydrogen, and natural gas. Two stage screw compressors are important in these industries because they provide a reliable and efficient source of compressed gas.

How Two Stage Screw Compressors Work

Basic Principles of Two Stage Screw Compressors

Two stage screw compressors work on the principle of positive displacement. The gas is drawn into the compressor and compressed between the rotors. The compressed gas is then discharged through an outlet. The compression process is continuous and produces a steady flow of compressed gas.

Components of Two Stage Screw Compressors

Two stage screw compressors consist of two rotors, bearings, seals, and a housing. The rotors are usually helical in shape and rotate in opposite directions. The bearings support the rotors and allow them to rotate smoothly. The seals prevent gas from leaking out of the compressor. The housing encloses the rotors and provides a space for the gas to be compressed.

Working Mechanism of Two Stage Screw Compressors

Two stage screw compressors work by drawing gas into the compressor through an inlet. The gas is then compressed between the rotors and discharged through an outlet. The compression process is continuous and produces a steady flow of compressed gas.

Advantages of Two Stage Screw Compressors
