What is a compressor? What are its types?
Compressors are motor-driven machines used to compress air and other gases. The word compressor, meaning "to compress," is of French origin and is used to increase the pressure of air and other gases in the atmosphere. Compressors have a wide range of uses in daily life. Two important factors to consider when buying a compressor are flow rate and pressure. Various compressor models are listed on Yapibahce.com . You can view small and large compressor models on our website.
How does a compressor work?
The operating principles of compressor models are fundamentally similar to those of vehicle engines. In compressors, the up-and-down movement of the motor compresses gasoline, resulting in combustion. This explosion and combustion then expels the gas. Compressor models operate on a similar principle. The gas or fluid obtained by the compressor is made usable with the help of the piston housing. Thus, compressed air is produced. Therefore, the compressed air and other gases are ready for application in various fields.
What are the different types of compressors?
Compressors are considered in two different types: positive displacement and dynamic. Positive displacement compressors work by increasing the refrigerant vapor pressure through the application of pressure to the compressor mechanism. Dynamic models, on the other hand, operate on a principle that allows for a constant increase in refrigerant pressure. Compressor types are further divided into piston, screw, centrifugal, axial, rotary, and jet types.
What is a reciprocating compressor?
Piston compressors are a type of compressor that uses a piston within a cylinder structure to reduce volume and increase pressure. These models, belonging to the positive displacement group, are called piston compressors because the piston follows a cycle of reciprocating motion. Piston compressors are generally used extensively in the industrial sector. Piston compressor models are further divided into single-acting piston compressors and double-acting piston compressors.
• Single-sided piston compressors collect air created with the help of discharge valves, and this air is then transferred to an air reservoir via a check valve system. The check valve system prevents the air transferred to the reservoir from returning.
• Double-acting piston compressors; the air, initially compressed at low pressure, is then transferred to the second and third stages with the help of a chiller. Similarly, the compressed air transferred to the air tank transfers the water vapor present in the atmospheric gas in the tank to the water relief valves.
What is a screw compressor?
These are compressor models that use a rotor instead of a piston to produce compressed air. As a type of positive displacement machine, screw compressors operate by one of their two screws moving the other, thus compressing air and other gases. Examples of areas where screw compressors are used include the automotive industry, the construction industry, and industrial facilities.
What is a centrifugal compressor?
In centrifugal compressor models with a spherical chamber , the operation works by accelerating the air drawn into the spherical chamber due to the effect of centrifugal force and rotational movements. The resulting air is then expelled through an air collection ring.
What is an Axial Flow Compressor?
Axial flow compressors, which are part of the Dynamic Compressor model group, are used to suppress fluid flow. This suppression is achieved with the help of a vane-shaped fan. Examples of applications for axial flow compressors include marine engines and small-scale power plants.
What is a rotary compressor?
Rotary compressor models perform the same function as piston compressor models. They maintain the pressure difference, the flow of refrigerant between the components, and compress the gas in the reservoir. However, rotary compressor models use a lesser gas compression method compared to piston models. This is considered the main difference between them.
What is a jet compressor?
Jet compressors are divided into two types: hydraulic compressors and gas-steam compressors.
• Hydraulic compressor models are compressor models that enable the use of water, which has a low pressure ratio, by applying pressure to the air without the aid of any industrial equipment. High-pressure water is lowered by applying pressure to the air. Following this step, the water separates from the pressurized air.
• Gas and steam compressor models; these compressor models have an outlet for compressed air to exit. As the compressed air exits through the outlet, it expands and moves rapidly, carrying the air with it. These models are generally used as thermocompressors in air blowing and ventilation machines in places where harmful vapors are not present.
What are the factors to consider when choosing a compressor?
How to Choose a Compressor? Let's try to explain it point by point.
• Post-purchase service: Providing services needed after purchasing a compressor, such as having service points, maintenance services, and the cost of spare parts, are important factors for long-term use.
• Determining the compressor's capacity: Choosing the right model and capacity based on the user's needs is one of the most important aspects. Not every model is suitable for every application.
• Determining the screw speed. Lower screw speeds offer longer service life and quieter operation. It's important to know that exceeding a certain level increases the likelihood of failure.
• Main motor selection: The main purpose of the motor is to drive the screws. Using a high-capacity motor increases the cost of compressed air by an average of 15-20%.
• Correct selection of the drive system: There are two methods for driving screws; belt-pulley and coupled. Both methods have their own advantages.
• Determining compressed air quality: Factors affecting compressed air quality include the amount of oil, moisture, and dust present in the air.
• Selection of working pressure: This is where needs come into play. It is important to know that using a working pressure higher than necessary will lead to increased energy costs.
• Improving the necessary environmental conditions or identifying the most suitable environment; reading reviews and conducting extensive research before purchasing a device; and ensuring that the devices have quality certifications are all important considerations.
• It is also essential to ensure that the warranty conditions are met.
Compressor Prices
Compressor models vary depending on the brand and model chosen. Because they are divided into different groups and have a wide range of applications , compressor prices also vary. Piston compressors, screw compressors, and rotary compressors are grouped and priced accordingly. The user's needs and preferred brand are influential factors. Users should allocate a specific budget and conduct thorough research to ensure they purchase the most suitable device.
