- 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. 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. One of those devices is the hand pump, which is used to inflate balls and other items. Hand pumps are usually made of wood or metal and have a simple manual pumping mechanism. 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. Some of the important milestones in the history of air compressors are: – In 1500 BC, foot operated bellows were born, used in metallurgy and ceramic production. In 1650, physicist Otto Von Guericke invented the vacuum pump, marking the first step for the study of compressed air. – In 1762, John Smeaton designed a blower driven by a water wheel, increasing the capacity of the air blower. – In 1776, John Wilkinson introduced a high-power explosive unit, considered the forerunner of today’s air compressor. – In 1799, Richard Trevithick used an air compressor to supply gas to a steam engine. – In 1829, George Medhurst developed a system for transporting goods by compressed air. In 1857, Werner von Siemens designed the first electric air compressor. – In 1872, Zénobe Gramme invented the AC motor, which allowed the air compressor to operate continuously and more efficiently. – In 1935, Hitachi introduced the small piston compressor. – In 1976, Hitachi introduced the first water-cooled screw compressor. 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 history of air compressors in Vietnam is related to the development of industries and services that use compressed air such as construction, manufacturing, automotive, pharmaceutical, food and beverage, agriculture and many other industries. Since when did Vietnam use air compressors is a difficult question to answer precisely, because air compressors are a device with many different types and applications in industrial, civil and military fields. Some information says that air compressors have appeared in Vietnam since the French colonial period, when explorers and miners used air compressors to supply air for pits or for drilling and vibration equipment. . According to other historical sources, the first air compressor in Vietnam was imported from France in the 1950s. This air compressor was used for metallurgical plants, oil refineries and rubber production. However, French compressors have high cost, large size and low efficiency. Therefore, in the 1960s, Vietnam began to import air compressors from other countries such as Japan, Taiwan, China and Korea. At that time, air compressors were mainly piston type, with small capacity and low efficiency. In the 1980s and 1990s, screw compressors began to appear and were more popular because of their larger capacity, higher efficiency and more energy saving. Currently, screw compressors are still the most popular type in Vietnam, accounting for about 80% of the market share. In addition, there are centrifugal compressors, rotary gears and blowers used for special applications. From the beginning of the 21st century to the present, air compressors in Vietnam continue to make great strides. The demand for air compressors is increasing due to the development of industries and services. Many types of advanced and energy-saving air compressors are imported from countries such as Germany, Italy, Sweden, USA… Some major air compressor companies in the world such as Hitachi, Atlas Copco, Ingersoll Rand.. . has been present in Vietnam through representative offices or distributors. Some domestic enterprises have also improved technology and product quality to compete with foreign air compressor companies. According to 6Wresearch, the Vietnamese air compressor market is expected to grow in the period 2020-2026F. The United Nations Industrial Development Organization (UNIDO) and the Vietnamese government have partnered to promote energy efficiency and reduce waste in the air compressor systems of Vietnamese businesses. The air compressor consists of the following main parts: Engine: is the source of power for the air compressor, can be an electric motor or an internal combustion engine. Compressor head: is the part that performs the air compression process, which can be piston compressor, screw compressor or centrifugal compressor. Reservoir: is the part that stores and stabilizes the pressure of compressed air, with different capacities depending on the capacity and purpose of the machine. Controller: is the part that adjusts and displays the operating parameters of the machine such as pressure, temperature, current, time, … Filter and separator: is a part to remove impurities such as dust, oil, moisture, … in compressed air to ensure the quality and life of the machine and equipment using compressed air.
