The Parameters of the Clean Spray Booth in the Workshop of Spray Painting Production Line

The clean spray cabin of the spray painting production line is generally placed in the spray booth. The spraying booth is composed of a chamber body, aerosol filter device, and an exhaust system.


Ⅰ. The size of the spray cabin equipment used for spraying in the painting production line

1. The spraying cabin for manual spraying, the main size of the spraying equipment is L900~1000×W600~800×H2000~2200mm, and the quantity is 2 sets;


2. The spraying cabin used for automatic spraying, the main body size of the equipment is L1500~1700xW3000~3200×H2600~2700mm, and the quantity is 1 set.


Ⅱ. The spray cabin of the spray painting production line

1. The spraying cabin of the coating production line is a dry spraying warehouse with upper air supply and side exhausting. The manual spraying cabin is a semi-closed type, and the automatic spraying cabin is a closed type.


The suction volume of the coating production line should not only prevent the escape of aerosol, but also avoid the phenomenon of over-exhaustion, improve the utilization rate of the coating, and make the spraying chamber of the coating production line have a slight negative pressure, the noise does not exceed 80 decibels, and a single set of manual The air extraction volume of the spray booth shall not be less than 3000m3/h, and the air extraction volume of the automatic spray booth shall not be less than 6000m3/h.


The warehouse body wall panels of the coating production line are made of high-quality stainless steel panels with a thickness of not less than 1.2mm. The panels are connected by bolts; the panels are sealed with sealing strips. The air duct is made of high-quality galvanized steel with a thickness of not less than 1.2mm.

The fan is placed on the roof of the spray booth (interlayer on the roof of the workshop). The base of the fan should be equipped with a vibration-damping pad, and the suction port of the fan should be equipped with a soft connector. Separately remove to leave enough space for maintenance of fan impeller and bearing.


2. The lighting brightness of the spray cabin of the painting production line is above 200 Lux, and the explosion-proof lighting lamp is placed above the spray booth.
