Screw compressors are specifically designed to handle the conveyance of various dry materials, from granules, cement and plastics to sand, flour, lime and silicates. Its body contains two types of screws, further called female screws and male screws. The internal thread is a screw with a concave entrance, while the external thread is a convex screw. Screw compressors run in opposite directions. The driving force is received by an internal thread. On the other hand, the external thread is responsible for transmitting the power driven by the internal thread. It goes through a set of so-called synchronous gears. Process Flow In addition to the main role of male and female screws in the compressor, this process has other important parts. When the screw starts to rotate, the entry process begins. This is where the air fills the air inlet, taking up the space between the two screws. The admission phase is followed by the compression phase. This is when the external thread stops or blocks the internal thread. At this stage, the rotation of the screw begins to decrease. Once the volume reaches the compressor outlet, the exhaust phase begins. The venting phase is when the screws are no longer in contact with each other. Complete reliability is obtained in this process, thus making screw compressors very useful in a variety of applications.
Common examples are hydraulic power systems, electric motors, and stationary and mobile applications. Different types and their specific applications One type is called a rotary screw compressor. This can be found in various gas compressors. It uses a mechanism with single or double reverse screw. When the mechanism is working, the gas can be sucked through the port of the cannula and then captured into a specific cavity. The gas is then vented to another port in the sleeve. This screw compressor is suitable for general industry, such as the use of diesel-powered trailer units in construction sites. Another specific type is an oil-injected screw compressor. This usually works in sealing and cooling gases. As the oil flows in this process, it will separate from the effluent stream before cooling and filtering. After that, the oil is recovered. Oil-free screw compressors are also examples of this industrial machine. Without any oil, the screws may compress the air. This type is relatively important in both medical research and the semiconductor industry.
