How Electrostatic Spraying Systems Work
Electrostatic spraying systems Inc. is a specialist electrostatic protection and management company in New Zealand that offer electrostatic discharge protection systems and related products. Electrostatic discharges occur when static electricity is created between any charged conductor or other conductive object and a non-reactive surface or substrate. The effects of static electricity can be very hazardous to both people and property. For this reason the installation of effective electrostatic protection systems is essential to ensure the safety of both people and property. Electrostatic spray equipment by definition to protect against electrostatic discharges and ensure the safety of both users and installations.
The Electrostatic Spray Makers Association (ESMA) is a not for profit organization chartered by the Ministry of Business, Skills and Innovation (MBI), New Zealand. The ESMA undertakes independent researches and research projects on new developments in electrostatic technology and methods to reduce the cost and risk of electrostatic discharges and promote the use of electrostatic systems where possible. The organization also educates the industry on the latest developments in electrostatic technology and uses its considerable experience and knowledge to promote the use of electrostatic systems.
Electrostatic spray guns are a very important part of many electrostatic spraying systems. These guns discharge high voltage (high-amperage) electrostatic discharges at very high rates of acceleration. Spray guns can be used both indoor and outdoor applications. For outdoor applications they are often installed on roofing, gutters, decks, and other structures that can be vulnerable to electrostatic release. For indoor purposes they are often fitted into computers, printers and television monitors to protect equipment from electrostatic release. It should be noted that whilst electrostatic spray guns can be used for protecting many commonly exposed electrical components they should not be used on vulnerable electrical faults in telecommunications networks as well as in any area where power lines are present.
Spray guns have several common design features. Firstly there is a common pump assembly, which is comprised of a housing protected by an external steel tube or housing and a high pressure supply feed. Spray guns operate with positive displacement, which means that a constant positive charge is maintained via a discharge line.
The primary benefit of these systems is that they provide excellent protection against electrostatic discharge. They prevent the Electrostatic release from penetrating the interior components. This will stop any damage being caused to those parts that do not have a conductive layer. Many systems consist of a discharge charger and accumulator. The discharge charger stabilizes the charge and is often designed to include a time-release feature, where the charge remains in full swing over a set period of time, after which it can be disposed of.
An alternative to a discharge path is the inclusion of a charge Couple. A charge Couple is used to “curb” the electrostatic discharge process. This is done by slowing down the discharge and ensuring that the charge does not travel through exposed parts such as wires. One benefit of using a Couple is that the charge is more evenly spread. The use of multiple Couples on the same system is also useful as it ensures that different areas of the system are not overloaded.
Electrostatic systems are commonly found in a wide range of industries. They can be found on plumbing, electrical and even military equipment. Some of the uses include: power washing (which is a very good commercial application), coating for machinery and other metal based items, preventing corrosion and protecting sensitive equipment. This type of system is now available for many different applications and can be customised to suit the application. For this reason these systems are constantly being modernised to provide better protection to people, assets and property.
An electrostatic system is designed to prevent the electrostatic discharge of dangerous static electricity. They do this by drawing in charge from a discharge path and then keeping it away from the area. An advantage of such systems is that they prevent damage to electrical equipment. The most common form of such systems is a charge Coupled Device (CCD), which is simply a long wire cable with a number of interconnections. These devices are very effective but need to be carefully installed to avoid damage and short circuits.
