Central Welding Fume Extraction System for Vocational and Technical College

Shenyang Vocational and Technical College No. 1 operation area has 20 manual welding stations. 2 sets of 11kw (9000-12000m³/h) Industrial Dust Collectors are selected to handle 10 stations each.

Each station has Extraction Arms to collection fumes, which is convenient to use, simple to operate, and has an ideal collection effect.

Industrial Fume Extractor adopts a Siemens Bide variable-frequency motor. A wind pressure sensor is installed on the pipeline to adjust the operating power of the fan in a timely manner according to the change of the wind pressure in the pipeline, which greatly reduces the energy consumption.

There is a cutting station and a welding station in the No. 2 operation area. A 3kw Dust Collector is selected, with air volume of 3000-3500m³/h, and dust hood collection method is adopted.

This method has a high collection rate and good airtightness, so the smoke and dust are not easy to spread.

There are 2 manual welding stations in No. 3 operation area. A 3kw Stationary Fume Extractor is selected, with air volume of 3000-3500m³/h, and universal suction arm collection methods is used, which is convenient and flexible.

There are 2 sets of welding robots in No. 4 operation area, each set has 2 welding robots. We use a 1.5kw Portable Fume Extractor (high negative pressure dust collector), with air volume of 0-1000m³/h, DC brushless frequency conversion fan, to address the fumes.

The collection method of suction hose is convenient and flexible, and does not hinder the work of the robot.
