Screw compressor timing gear
Rotary-screw compressors use two very closely meshing spiral rotors to compress the gas. In a dry-running rotary-screw compressor, timing gears ensure that the male and female rotors maintain precise alignment without contact which would produce rapid wear. In an oil-flooded rotary-screw compressor, lubricating … Visa mer A rotary-screw compressor is a type of gas compressor, such as an air compressor, that uses a rotary-type positive-displacement mechanism. These compressors are common in industrial applications and … Visa mer The screw compressor was first patented in 1878 by Heinrich Krigar in Germany, however the patent expired without a working machine being built. The modern helical … Visa mer Among rotary-screw compressors, there are multiple control schemes, each with differing advantages and disadvantages.
