A centrifugal compressor refers to a turbine compressor with an exhaust pressure higher than 0.015MPa and where the gas mainly flows radially. It is also known as a radial flow compressor. Those with an exhaust pressure lower than 0.2MPa are generally also called centrifugal blowers. It is widely used in various process flows to convey air, various process gases or mixed gases and increase their pressure. In industry, they are often named according to their uses or types of gases, such as blast furnace blowers and ammonia centrifugal compressors, etc. Centrifugal compressors play a significant role in various sectors of the national economy, especially in industries such as metallurgy, petrochemicals, natural gas transportation, refrigeration, and power, where they are widely applied.

In recent years, against the backdrop of economic globalization and fierce competition, the foreign centrifugal compressor manufacturing industry has also undergone continuous mergers and acquisitions and reorganizations.

Let's first take a look at the well-known centrifugal compressor manufacturers in the United States in this article:

Ingersoll Rand

Ingersoll Rand Corporation of the United States was founded in 1871, with its full name being "Ingersoll Rand - Rand Corporation". Its headquarters is located in Woodcliffe Lake, New Jersey, USA. The company's products include compressed air systems, building hardware products, construction equipment, golf cars, tools and transportation refrigeration systems.

Ingersoll Rand began manufacturing centrifugal compressors in 1911 and installed the world's first 100 m³/h steam turbine-driven multi-stage air compressor in 1912. In 1928, it launched a compressor energy recovery system. In 1940, it produced centrifugal compressors for catalytic cracking. In 1949, it started manufacturing steam turbine-driven centrifugal compressors. The assembled high-core compressor was introduced in 1958. Since the successful development of Ingersoll Rand's CENTAC centrifugal air compressor (multi-axis gear-driven combined centrifugal compressor), it has been highly favored by users. To date, 12,000 units around the world have been operating safely and stably for a long time. The CENTAC centrifugal air compressor is a fully assembled, motor-driven, single-layer structure, single-stage suction and single-stage exhaust centrifugal air compressor that provides 100% oil-free air. Its flow rate range can be from 25 to 850m ³ /min, and the exhaust pressure range is from 0.8 to 4.0 m ³. The compressor and motor are connected by flanges and couplings. The entire unit, including the cooling system, control system, oil lubrication system and other auxiliary equipment, is all installed on a common chassis.

DRESSER-RAND

The American company Desalain is one of the largest compressor manufacturing companies in the world.

The company has departments such as the Steam Turbine, Electric Motor and Generator Department, Turbine Machinery Department, Engine Process Compressor Department, Gas Compressor Department and Product Support Department. The headquarters of the Turbinate Machinery Department is located in Orion, New York. The company's main products include centrifugal compressors, axial flow compressors, steam turbines, gas turbines and reciprocating compressors, high-temperature industrial gas expansion turbines, blast rod compressors and axial flow centrifugal compound compressors.

CAMERON Company

Headquartered in Texas, USA, it was formerly known as Cooper Turbine Compressor Co., LTD.

该公司从50年代初开始制造离心压缩机，到50年代中期，试制出5000马力燃气轮机驱动的管线离心压缩机。此后不久又制造了10000马力燃气轮机驱动的管线离心压缩机。从1964年起制造合成氨离心压缩机，1972年起制造合成氨离心压缩机。1972年以后，又集中力量发展用于天然气工业的离心压缩机。目前世界上运行中的管线压缩机约有45%是该公司的产品，为管线压缩机配套的燃气轮机约有60%是该公司产品。公司离心压缩机制造技术曾向墨西哥康杰特公司、法国克勒苏一卢瓦公司、日本川崎重工公司和神户制造所及前苏联输出。

该公司现生产的离心压缩机水平剖分型有RB-S、RC-S、RD-S、RE-S、RF-S等形式，最大进口流量为160~1715m3/min，最高排气压力为4.12~1.72MPe;简型有RB-B、RC-B、RDB、REB、RFB等型号，最大进口流量为178630m3/min，最高排气压力为44.49~8.5MPa.

GE 通用电气动力部

1994年以来，GE并购了新比隆、A-C等压缩机制成厂成立GE通用电气动力部，成为压缩机行业的领先企业。

1. Xinbilong Company

The former Italian New Billon Company was founded in Florence, Italy in 1842. It was initially a foundry and began to engage in mechanical engineering at the beginning of this century. At present, we mainly produce machinery and equipment for petroleum and petrochemical industries. At the same time, we also produce special machinery and equipment for the nuclear industry and textile machinery and other products. The company has a total of 7 production plants in Italy, among which the main production plant is located in Florence, which is also the location of the company's headquarters. Here, reciprocating compressors, centrifugal compressors, steam turbines and gas turbines are produced. From component processing to machine assembly, all are completed within the factory. There are multiple test benches in the factory, allowing for the simultaneous commissioning of several units (including the drive units). Centrifugal pumps, pressure vessels, heat exchangers, valves, textile machinery and other products are respectively produced in other factories.

The company can produce mechanical products such as compressors, steam turbines and centrifugal pumps in accordance with API standards, and also manufacture various pressure vessels and heat exchangers in accordance with ASHB and TEMA standards. Many of its products have been put into use in Chinese factories. The main units currently operating in China include: cracking gas compressors for ethylene plants, ethylene compressors, propylene compressors and methane compressors. Synthesis gas compressors, carbon dioxide compressors and liquid ammonia pumps in fertilizer plants, etc.

2. American A-C Compressor Company

The American A-C Compressor Company has developed based on the compressor division of A1lis-Chalmers. Up to now, it is A comprehensive compressor manufacturer capable of producing various types of compressors such as centrifugal, axial flow, screw, and rotary vane compressors. With a history of nearly 60 years, it has large factories in both the United States and Canada. Its testing center can test power up to 13050k and collect modern aerodynamic performance data. The annual sales of A-C Compressor Company in the United States range from 70 to 80 million US dollars. Among them, 65% are centrifugal compressors, 18% are rotary vane compressors, and 17% are screw compressors. These products are mainly used in petrochemical, natural gas and other chemical plants.

Multistage centrifugal compressors are available in horizontal split type (≤50bar) and vertical split type (<350bar). The centrifugal compressors of Company A-C can meet the API617 standard.

ELLIOTT

ELLIOTT, headquartered in Janet, Pennsylvania, USA, was founded in 1895. ELLIOTT's centrifugal compressors are widely used in industries such as air separation, steel, petrochemicals, textiles, pharmaceuticals, power generation, automobiles, glass, electronics, and papermaking. Eliwater Company exported centrifugal compressors and steam turbines to China as early as 1978.

The product series include:

Process-oriented products: Process centrifugal compressors, process axial flow compressors, steam turbine machinery; Industrial gas turbine products: factory-type PAP series centrifugal air compressors, small steam turbines, etc. In 2000, ELLIOTT Company was acquired by Japan's EBARA Company and established ELLIOTT-EBARA Turbomachinery Company, with its headquarters located in Tokyo. In October 2003, ELLIOTT sold the factory-type PAP series centrifugal air compressor production line to Fusheng Group and established FSELLIOTT. At the same time, Fusheng Yilida (Shanghai) Compressor Co., Ltd. was set up in Shanghai to be responsible for the production, sales and service of centrifugal compressors. This makes the air compressor product series of Fusheng Company more complete.
