IMPROVING INDUSTRIAL DISPENSING WITH PNEUMATIC VALVES

Dispensing ValveThe simple pneumatic dispensing machine is generally low cost and almost ubiquitous. They improve the application of materials like single part adhesives, coatings, sealants and inks, by enhancing a manual process to one which is more controlled and repeatable, while health and safety benefits include less mess, less exposure to potentially hazardous chemicals and fewer RSI issues.

These systems work by filling an industrial syringe or barrel with the liquid material. Pulses of air then push the liquid out of the other end, usually through a dispensing needle or tip. The quantity dispensed can be varied by the size of the needle orifice (from as small as 0.15mm), the pressure applied and the time of the air pulse triggered by footswitch, finger switch or automation. They may be hand-held or mounted on positioning robots or rotary tables.

Less than 1% variance is often easily achievable, and 0.1% not uncommon. Digital timers further improve accuracy.

Integrating Inspection-Based and Reliability-Based Information

Reliability MaintenanceThere are many sources of machinery health and production availability information available to an organization's maintenance and operations staff. Two of the most commonly used sources of information are scheduled inspection of machinery and condition monitoring.

In most cases, scheduled inspection of machinery has been managed through a plant
