Fluidics: the answer to problems of handling hazardous fluids

摘要

Dangerous fluids must be kept within a containment. This may be a problem in emergency situations which almost inevitably happen from time to time in mechanical pumps and flow control valves due to material fatigue, seizing, or screws getting loose. During maintenance and repair the fluid may be exposed. A solution is offered by no-moving-parts maintenance-free fluidics. Three classes of devices are discussed: A) passive flow controllers, B) valves controlled by an external signal, C) fluidic pumps driven by alternating flow.
