It’s no secret that when using them for fluid dispensing, there is an erratic fluctuation of air supply that comes from compressors. This has resulted in numerous firefights to combat this common problem in the fluid dispensing industry.
The fluid dispensing firefight process focused on the following components:
Syringe and Piston
Syringe and piston designs were altered several times to extinguish the fire but it wasn’t the root cause of erratic fluid dispensing.
Dispense Tip
It was originally thought that the restrictions at the end of the syringe barrel luer and restrictions inside the dispense tip could be the problem. Many new styles of dispense tips were developed in an attempt to combat the problem to no avail.
Air Compressor and Timing Circuit
In an attempt to achieve better air solenoid performance, analog time was replaced by digital timers. Filtration systems were added to stop moisture contamination of control boxes, syringes, and the assembly fluid. Moisture and time control achieved little results.
Volumetric Displacement
As the space between the piston and air source gets larger the time of the dispense cycle and force of the air pressure must increase otherwise the dispense dot gets smaller as the syringe empties. This problem requires hourly adjustments of the air pressure and time settings causing a high level of frustration with the operators.
All of the above are examples of firefighting byproducts of the root cause of the problem. It’s a waste of time and money. Automating a problem isn’t a sufficient solution. The root cause of erratic fluctuation in fluid dispensing is air pressure and it can no longer be ignored.
