A conical screw compressor is an offshoot of the conventional screw compressor. In a typical screw compressor, two meshing helical screws or rotors are mounted side-by-side in a housing. The rotors spin in opposite directions and draw air into the cavities between them. Volume decreases as air progresses along the rotors and compresses air, which […]
Condition monitoring for compressed air piping
The Transair business unit of Parker Hannifin has announced the next evolution in compressed air piping with its new Condition Monitoring Technology, which lets end-users track the status of their compressed air piping systems. The setup uses sophisticated wireless sensors to monitor a compressed air piping network, alert users to system changes, and provide critical […]
Rethinking manual handling in the digital factory
Digitalization is on the rise in factories, and manual handling is no exception. Increasingly customized products go hand-in-hand with increasingly complex processes, and the way workers deal with goods needs to adapt. Intelligent handling devices play an important role in making this growing complexity manageable, according to the engineers at J. Schmalz GmbH, Glatten, Germany. […]
Schmalz compact ejector generates vacuum in tight spaces
Small, powerful and scalable SCPM vacuum generators from J. Schmalz GmbH, Glatten, Germany, represent a new series of compact ejectors that can be integrated directly into a vacuum gripping system thanks to a slim, lightweight design. The new SCPM family was developed in response to the growing demand for space-saving, decentralized vacuum generators that combine […]
New generation air compressors focus on efficiency, sustainability
The latest air compressors hitting the market benefit from variable-speed drives, oil-free operation and IoT capabilities. Compressed-air was a key fluid power technology on display at this month’s Hannover and bauma trade fairs in Germany. Between the two shows, scores of exhibitors displayed hundreds of new and upgraded products. One area of emphasis centered on […]
Electronic proportional flow control
The new EV 10 electronic flow control valve from C.Matic, Giussano, Italy, includes a circuit board, dc motor, tiny gear box and a needle valve. The PCB reads an electric input signal, processes it, and directs the servo-actuator to move the needle valve inside an orifice. The unit ensures linear flow rate changes that are […]
What is a scroll compressor?
Scroll compressors are positive-displacement devices that work by internal compression. Air (or other gas) is drawn in, trapped, reduced in volume and, finally, discharged at the outlet port. The concept of a scroll compressor has been around for more than a century, but it took more-recent advances in manufacturing technology to make the product viable. […]
What are alternatives to Cv for rating flow?
The flow capacity of valves, connectors and other components in pneumatic systems is often expressed in Cv. (See, “What is the flow coefficient Cv?“) However, other methods and standards are also available to express flow capacity. Here are some important alternatives. Sonic conductance In place of Cv, some manufacturers choose to publish the sonic conductance, […]
What is the flow coefficient Cv?
In the pneumatic industry, Cv is one standard for expressing the flow capacity of devices used in pneumatic systems. However, there are multiple other standards that also express flow capacity, including effective orifice size and normal liters per minute, as well as measurements of actual flow rates at specific pressure differentials. These methods are not […]
Vacuum generation for handling technology
Future trends point to mobile, autonomous and energy efficient systems. Contributed by Harald Kuolt, Functional Coordinator Pre-Development, J. Schmalz GmbH, Glatten, Germany Automated production is the key for marketable products. Automation technology makes it possible to cut process costs, increase output and productivity, and raise quality—all of which lead to highly efficient production and better, […]
