Jetting: A New Fluid Dispensing Technology

Dispense valve

A fluid dispenser, as the name suggests, is a dispense mechanism for fluids that delivers mechanical benefits to the application it is used for. Some are used for large refineries for oil and other liquid products like chemicals and food. Some are used in small applications like printing and circuit board manufacturing. The dispensing mechanism includes a lever or a control valve and an actuator. The flow of fluid is controlled by manipulating these controls. They can be mechanical, manual or a more advanced electronically actuated dispense valves.

One to the most advanced way to dispense fluid for small applications which is better and more efficient is called jetting technology. The fluid in jetting technology is accurately ejected through a small nozzle in discrete droplets for an even distribution of fluid to a surface. The area of application can be controlled by altering the nose or the tip of the nozzle. Small amounts can be precisely positioned to a location for electronic controls where the computer determines the amount of fluid to be applied to a specific area.

Using this technology, it includes increase in productivity by reducing the up and down vertical height movement, more precise fluid ejection, and high controlled fluid flow rates. It has become a standard production process equipment in electronic companies, printer manufacturing, and chemical treatment for small circuit boards, stacked die, fuel cells, LED manufacturing, flat panes monitors and chips for laboratory purposes. This new jetting technology is made available by large pressure tank manufacturers all around the globe.

For large and greatly pressurized applications, jetting can still have a large role in getting the job done. If there is a problem in concrete that is unwanted, high pressure water jetting can be used to remove it. The cement can be eroded by a fast flowing high pressure water jet. The eroded concrete can then be easily washed away by water and into the disposing bin. For reinforced concrete with steel bars on the inside, an abrasive can be added to the jetting water to cut through the bars inside. This technique is widely used because there is no dust produced during the process.

Jetting can also be used in removing paint jobs, rust and paint impurities without damaging the metal or concrete at a certain level of pressure. Impurity build-up on gates, walls, hooks, and large ship carriers reduces the paint job efficiency and leads to low-quality finish. The use of chemical strippers and incinerators are effective but are very dangerous to the operator which exposes them to hazards. High-pressure water rushes through the paints that make short work for primers, paints, outercoats, and gunk. The water jet can clean faster and more thoroughly than other methods.

The use of jetting technology is very advantageous for businesses because it provides significant labor savings than traditional labor, low operating costs because it is very efficient and energy-saving, environment friendly because of the use of water which is not a harmful chemical, and the system is easy to use and easy to maintain.
