Rotary airlock; The basic use of the rotary airlock feeder is as an airlock transition point, sealing pressurized systems against loss of air or gas while maintaining a flow of material between components with different pressure and suitable for air lock applications ranging from gravity discharge of filters, rotary valves, cyclone dust collectors, and rotary airlock storage devices to ...
The history of the bar puller begins with the introduction of the NC/CNC lathes in around 1980. At this time lathes were changed to permit inexpensive and economical production of small or medium-sized batches. The bar puller serves to draw bars into the lathe without operators having to feed the machine with material each time it is required.
The biggest advantage with the hose pumps over the roller pumps is the high operating pressure of up to 16 bar. With rollers, max pressure can arrive up to 12 bar (170 psi) without any problem. If the high operating pressure is not required, a tubing pump is a better option than a hose pump if the pumped medium is not abrasive.
A centrally located and electrically-powered compressor powers cylinders, air motors, pneumatic actuators, and other pneumatic devices. A pneumatic system controlled through manual or automatic solenoid valves is selected when it provides a lower cost, more flexible, or safer alternative to electric motors , and hydraulic actuators .
The "live" zero of 0.2 bar or 3 psi is set by the bias spring which ensures that the device is working in its linear region. The industry standard ranges of either 3-15 psi (USA), or 0.2 - 1.0 bar (metric), is normally used in pneumatic PID controllers, valve positioning servomechanisms and force balance transducers.
