How the spraying chamber works
It is possible to obtain high-quality powder coatings only by following the technology and using professional equipment. The powder is applied in a spray chamber where the painted product is suspended. They are specially designed for powder handling and are not suitable for liquid paints.
Spray chamber device
The spray chamber is a sealed box, closed on all sides, with the purpose to separate the powder spraying area from the entire room and to filter the air.
The chamber is covered with powder paint inside. It has been designed for quick cleaning in case of first color changing.
The spraying chamber has a working box, a filter unit and a control panel.
The working chamber is the place where the product is loaded into. It is a one-piece welded structure that has an opening for loading, painting and unloading parts.
The chamber is equipped with a control panel and a compressed air preparation device.
They are located outside. This allows you to monitor the operation of the device, being at a safe distance from the working area. The painter turns the camera on or off on the control panel, controls the blowing impulse of the filter elements and lighting. It also has the function of protecting the device from overloads and short circuits.
The spray chamber has a built-in filter unit in the form of a sealed box-type design with a removable top cover. It also has an opening for the exhaust ventilation. It is important to change spray chamber filters from time to time as they can become clogged. Clean them automatically or manually.
How the spray chamber works
Powder paint is deposited on the product due to the electric field. But not all paint particles settle on the surface. They are collected in the chamber and pass through the filter and recuperator. And then they get to work again.
For this, the recuperator has replaceable fabric filters, a special fan for the spray chamber to form an exhaust draft, a receiver and an air supply system.
The hood collects contaminated air from the working area and the powder particles settle on the filter. They are cleaned of impurities and dirt and sent to the bunker.
Clean air is regularly supplied to the working area to replace polluted air.
Filters are cleaned with compressed air. If it is necessary to change the color, then they are replaced with new ones.
Types of spray chambers
All spray chambers are divided into several types. Each one is designed for a different job.
Single-station spraying chambers are equipped with one working opening. The product is loaded, painted and unloaded. These models are suitable for coating small products. Great for painting flat parts.
Two-station spraying chambers are equipped with two working openings for loading and unloading products. And also doors for painters. They are suitable for coating large parts of any shape.
Two-station cameras are provided with a transport system that independently carries the product through the device.
The spray chamber hood can be single-engine or twin-engine. The difference lies in the fact that the former supply clean air from above, while dirty air exits through the hole below. And the second blows air from above with one fan, and from the bottom they take in another.
Which camera is best for production and how much power it should have, only a professional can calculate for sure. Therefore, we advise to contact a specialist to save your time and money.
