The evolution history of air compressors

The evolution history of air compressors

The (mechanical) vacuum pump made in Germany in 1640 is the originator of modern air compressors.

　　 Around 1800, the first single-stage (reciprocating piston) air compressor was made in the UK, and its discharge pressure was 1.38MPa (gauge pressure).

　　 In 1829, the first two-stage reciprocating air compressor with intermediate cooling was designed in the UK.

　　 In 1878, Burckhardt Maschinenfadrik AG, Switzerland, produced the company's first air compressor with a control slide valve for air distribution.

　　 In 1878, the German H. Krihar first proposed the concept of an air compressor without internal compression. This air compressor is the screw air compressor in the future. However, due to the limitations of the process technology at that time, there are only ideas and cannot be manufactured.

　　 In 1888, the compressed air station in the pneumatic system of Paris, France, had 14 reciprocating air compressors with a total power of 1500kw.

　　 In 1902, Ingersoll-Rand Co. made the first mobile reciprocating air compressor.

　　 In 1904, Atlas Sweden developed the first piston air compressor.

　　 In 1907, the Swedish Atlas Company produced the company's first mobile reciprocating air compressor. The internal combustion engine and the single-stage air compressor were both horizontal and shared a crankshaft. This is q*s* integral motorcycle compressor.

　　 In 1930, a mobile air compressor named Monodloc came out. It is essentially a diesel motorcycle air compressor: vertical, 4-cylinder without crosshead, two-stroke, diesel-powered cylinder, which directly drives the vertical on the same fuselage through the same crankshaft, 2-cylinder, two-stage, single-acting, There is a crosshead compression cylinder.

　　 In 1931, Morthington Corp. produced the company’s first opposed air compressor, which later developed into today’s BDC symmetrical balanced air and gas compressor series.

　　 In 1931, Morthington Corp. produced the company’s first opposed air compressor, which later developed into today’s BDC symmetrical balanced air and gas compressor series.

　　 In 1934, the reciprocating cylinder non-lubricated air compressor of KSB of Germany was made. In the same year, the first reciprocating cylinder non-lubricated air compressor produced by the Wurzen Machinery Manufacturing and Casting Plant in Germany used graphite rings as the material for the reciprocating sealing elements.

　　 In 1934, Professor Alf Lysholm of the Royal Institute of Technology in Sweden was the first person to design a screw air compressor and its rotor tooth profile. Since then, screw air compressors have been produced and applied. The screw engine at this time, although theoretically already possesses some of the advantages he needs, it must have a very large displacement to meet the requirements of the gas turbine. Therefore, the screw machine has not been applied in this field. Nevertheless, Alf Lysholm and his Swedish SRM company continue to conduct in-depth research on the application of screw air compressors in other fields. Until 1937, Alf Lysholm successfully developed two types of screw compressor test prototypes in SRM Company, and obtained satisfactory test results. At the end of 1935, Sulzer Brothers Ltd of Switzerland manufactured the first prototype for the Zurich brewery. One labyrinth cylinder oil-free lubrication air compressor.

　　 In 1946, James Howden, a British company located in Scotland, was the first company to obtain a license to produce screw air compressors from SRM in Sweden. Subsequently, many companies in Europe, the United States and Japan have successively obtained such licenses from SRM in Sweden to engage in the production and sales of screw air compressors.

　　In 1957, the oil-injected screw air compressor was introduced, which further improved the shortcomings of the previous screw air compressor, so it has been widely used. In the same period, Yongbang Machinery and other brands have successively purchased air compressor parts from q*, and assembled them into self-owned brand screw air compressors.

　　 In 1960, the famous DT4 short-stroke air compressor and ER8 low-power consumption air compressor of Atlas Company of Sweden came out.

　　 In 1960, French B. Zimmern proposed the idea of ​​a single screw compressor and obtained the patent right. In 1962, the first prototype was trial-produced, and it was officially produced and put on the market by the French Peugeot in the early 1970s.

　　 In the late 1970s, countries such as the Netherlands, the United Kingdom, and Japan successively developed and produced single-screw compressors for refrigeration and air-conditioning, in two forms: open type and semi-closed type.

　　 At the end of the 1980s, technology was promoted, and single-screw compressors were developed to compress various gases (including air, flammable, explosive and toxic gases) used in petroleum, chemical, mining and other industries. At present, manufacturers in Britain, France, the United States, Japan, the Netherlands and other countries can produce single screw compressors of different specifications.

　　 In 1961, the oil-injected screw refrigeration compressor and screw process compressor were successfully developed. After the subsequent continuous basic theoretical research and product development test, the continuous improvement of the rotor profile and the successful development of special rotor processing equipment, the superior performance of the screw air compressor has been continuously brought into play. Since then, various screw air compressors have continued to appear.
