What is the Air Compressor?

Air compressor is a mechanical device designed to compress air into a certain space, creating a source of compressed air with a higher pressure than the incoming air. This device uses a power source or an internal combustion engine to generate gas pressure to compress air or other gas such as nitrogen, argon, oxygen, acetylene, etc. Air compressors can be used to supply compressed air to a wide range of equipment and applications ranging from industrial machinery to construction equipment. Other applications of air compressors may include polishing, painting, cleaning, tire inflating, pressure gauge pumping, etc. Air compressors come in many different types and sizes, from as small as a hand tool to as large as an industrial air compressor. Common types of air compressors include piston compressors, screw compressors, and screw compressors. Each air compressor type has its advantages and limitations, and is selected based on specific requirements and applications.

 

Development history of the Air Compressor in the world and in Vietnam

History of the air compressors in the world

Before the air compressor was invented, people used basic tools like pump rods to create enough air pressure to blow wax, swim, and pump wheels. However, in the early days, people also developed devices that used dynamics to create air pressure.
In addition, hand propulsion devices, consisting of a propeller unit and a propellant pump, are also used to produce sufficient air pressure for use in various applications.
However, air compressors were really developed and popularized in the 19th century, when technology and materials were significantly improved.

Air compressors today come in many different types and sizes, tailored to specific applications. Some common types of air compressors are: piston compressors, screw compressors, centrifugal compressors, convection compressors, and mixed flow compressors. Air compressors are used in industries such as: industrial production, construction, medical, transportation, tires, artificial snow making and home appliances.

The problems frequently happen when using Air Compressors in industrial and construction

Air Compressors are an important piece of equipment in many industries and construction. However, when using an air compressor, users may encounter some common difficulties as follows:

• Damage due to overload: Air compressors can be overloaded when operating continuously with higher than allowed pressure, or when there is a problem with voltage, temperature, or lubricating oil. Overloading can cause damage to components such as the motor, piston, valve or inverter. To avoid overload, users need to regularly check the specifications of the air compressor and adjust them in accordance with the working conditions. In addition, it is necessary to maintain and replace damaged parts in a timely manner.
• Air leaks: Air leaks are one of the causes of wasted energy and reduced efficiency of air compressors. Gas leaks can occur in duct connections, relief valves, safety valves or gas consuming devices. To detect and correct gas leaks, users need to periodically check pipes and related equipment, using methods such as listening to sounds, using soap solutions or ultrasonic devices.
• Dirt pollution: Dirt can contaminate the compressed air and reduce the quality of the product or the production process. Dirt can enter the compressor through the air intake or through the air consuming devices. To prevent contamination by dust, users need to install air filters in appropriate locations, clean and replace the filters periodically, and keep the work environment clean.
• Frictional heat gain: Friction between the moving parts of an air compressor can cause heat gain and shorten the life of the machine. Increased heat can also affect the quality of the compressed air and cause condensation. To minimize frictional heat gain, users need to use high-quality lubricant suitable for the type of air compressor, check and replenish oil periodically, and install cooling devices such as fans or Radiators.

Electric and Diesel Air Compressor, which one is better?

Engine and Electric compressors are two common types of air compressors on the market. Here are some comparative characteristics between them:

Engine Air Compressor	Electric Air Compressor
Use fuel such as gasoline or diesel to power the air compression process.	Use mains electricity or batteries to operate.
Can operate in places where there is no power source or there is an unstable power supply.	Dependent on power and can be interrupted in the event of a power failure.
Usually have a larger capacity and can compress air at higher pressures.	Electric air compressors are typically smaller in capacity and suitable for lighter applications.
Emit high noise and exhaust fumes, polluting the environment and affecting the health of users.	Operate quietly and are environmentally friendly.
Need regular maintenance and replacement of parts to ensure efficiency and safety.	Less expensive in terms of maintenance and repair costs.

Electric air compressors are usually compact in size, easy to move and install, do not make loud noises and have no emissions. In addition, electric air compressors also meet the needs of applications such as spray painting, packaging, dust blowing, use in electronics factories or areas where no oil is required. However, the durability of an electric air compressor is often not as high as that of a motor, and operating and maintenance costs can be higher.

Engine air compressors are generally more durable and can operate for a long time without problems. In addition, engine air compressors often have stronger air compression capabilities, meeting the needs of applications such as painting, sandblasting, mining, food processing, steelmaking, cement and other industries. However, the engine air compressor has a higher noise, is difficult to move and install, needs a place to escape the exhaust gas and produces emissions that pollute the environment. In addition, motorized air compressors require higher maintenance and operating costs than electric compressors.

Both electric and motor compressors have their own advantages and disadvantages and depending on the needs of use and specific conditions, there will be a suitable choice.
