Starting in 1946, Ajax gas engines became a primary product utilized by oil and gas companies. In 1958, the first Ajax integral engine / compressor was manufactured and was specifically designed for field gas gathering applications. It was a DPC 230 and was soon followed by a complete line of Ajax integral engine-compressors from 30-360 horsepower.
Two years later, it moved its headquarters to Houston and in 1968 began the Cooper Rolls joint venture with Rolls-Royce to market gas turbines. [2] 1987 marked the acquisition of Joy Industrial Compressor Group, founded in 1955 in Buffalo, New York, which was renamed Cooper Turbocompressor as part of Cooper Compression. One year later, Cooper ...
World War II poster promoting Cooper-Bessemer engines. Cooper-Bessemer was a brand of industrial engines and compressors manufactured in Mount Vernon, Ohio.The Cooper-Bessemer Corporation was formed when the C. & G. Cooper Company (founded in 1833) and the Bessemer Gas Engine Company (founded in 1899) merged in 1929.
A similar single stage axial compressors can only increase the pressure by a factor of 1.2 but axial compressors have an advantage over centrifugal compressors because of their ability to have multiple stages. In the multi-staged compressors, the pressure is multiplied from row to row which can increase the pressure by a factor 40.
The compressor will recover to normal flow once the engine pressure ratio reduces to a level at which the compressor is capable of sustaining stable airflow. If, however, the conditions that induced the stall remain, the return of stable airflow will reproduce the conditions at the time of surge and the process will repeat. [2]
A compressor map is a chart which shows the performance of a turbomachinery compressor. This type of compressor is used in gas turbine engines, for supercharging reciprocating engines and for industrial processes, where it is known as a dynamic compressor. A map is created from compressor rig test results or predicted by a special computer program.
The gas compression process of a rotary screw is a continuous sweeping motion, so there is very little pulsation or surging of flow, as occurs with piston compressors. This also allows screw compressors to be significantly quieter and produce much less vibration than piston compressors, even at large sizes, and produces some benefits in efficiency.
Diagram of a typical gas turbine jet engine. Air is compressed by the compressor blades as it enters the engine, and it is mixed and burned with fuel in the combustion section. The hot exhaust gases provide forward thrust and turn the turbines which drive the compressor blades. 1. Intake 2. Low pressure compression 3. High pressure compression ...
