REMANUFACTURED SCREW COMPRESSORS
The operating principle of remanufactured screw compressors has been known for more than 100 years. However, it took nearly 75 years until the wide ranging opportunities for this type of compressor were recognised, but this time was also needed to create the technological preconditions of its industrial manufacture. This refers to the compressed air lost due to in-efficiency in the design of the compressor. In a reciprocating compressor, some of the air will seep back past the gaps in the piston rings. Today, the use of remanufactured screw compressors is widespread and displaces to an increasing extent the established piston, rotary and other compressor systems. The first prototype of a screw compressor was built in 1943. This was an oil-free compressor with counter- rotating rotors not touching each other. The principal runner drove the auxiliary one via a synchronous transmission in this instance. |
