In this study, the fracture of piston for rock drill produced from case hardening steel is investigated. In order to study the causes of the fracture, specimens prepared from the damaged pistons were subject. [pdf]
The screw compressor is identical to the screw pump except that the pockets of trapped material get progressively smaller along the screw, thus compressing the material held within the pockets.OverviewA rotary-screw compressor is a type of , such as an , that uses a rotary-type positive-displacement mechanism. These compressors are common in industrial application. .
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. .
The capacities of rotary-screw compressors are typically rated in (HP), ()* and (PSIG.) For units in the 5 through 30 HP range the physical siz. [pdf]
