Typical Pain Point: When Robotic Production Meets Smoke Pollution

In the modern steel structure manufacturing sector, automated welding technology has become the core driver for productivity enhancement. In a steel processing enterprise's workshop, five robotic welding arms operating simultaneously generate over 30 cubic meters of welding fumes per minute. These particles containing iron oxide, manganese compounds, and other harmful substances—even with traditional cartridge dust collectors and respiratory protection equipment—remain difficult to block at the source. The moment welding arcs generate, fumes spread to all corners of the workshop with thermal airflow, causing PM2.5 concentrations in the work area to exceed standards by 300% for long periods. This not only threatens workers' health but also affects the precision of robotic sensors due to dust deposition.

This client's mainly processes are welding metal products and electrical equipment, and is responsible for the installation and maintenance of mechanical equipment. The workshop has 5 robotic welding arms that produce a large amount of welding fumes. Although professional protective equipment has been provided for the workers, it still cannot solve the problem of dust pollution at source.

Why install high vacuum fume extractor

Considering the distinctive conditions of the client's operation, Power Space decided to install high vacuum fume extractor. This particular type fume extractor presents several advantages:

1.Collecting fumes at the source with high collection efficiency. The source collection of dust achieves a collection efficiency of over 99%, ensuring a significant improvement in the air quality within the production workshop. This efficient collection method captures the dust the moment it is generated, thus preventing its dispersion in the workshop and providing employees with a cleaner and safer working environment.

2.Doesn't affect the welding quality and doesn't disrupt the welding shielding gas. The system is ingeniously designed to have no impact on the quality of robotic welding and does not disrupt the protective gas environment crucial to the welding process. This ensures both the quality and appearance of the weld joints and maintains the stability of the welding process, guaranteeing the final product quality.

3. Compatible with different robot welding torches. The diameter of the exhaust duct is only 30 millimeters; this compact design allows it to easily fit various models of robotic welding torches. Whether for large or small welding projects, this system can adapt flexibly, greatly improving the versatility and applicability of the equipment.

4. Less 1/2 power consumption than ordinary welding fume extractors. Compared to traditional welding fume extractors, the power consumption of this device is only half, meaning that while achieving efficient dust collection, it also significantly reduces energy consumption, thus lowering operating costs. This energy-saving design not only helps the company reduce operational expenses but also aligns with the environmental concept of energy conservation and emission reduction, contributing to the sustainable development of the enterprise.

Customized Solutions with High Vacuum Fume Extraction

Aiming at the enterprise's complex needs, Power Space's technical team proposed an integrated "source capture + high-efficiency purification" solution. The core equipment, a high-vacuum fume extractor with a diameter of only 30mm, breaks through traditional equipment limitations with these technological innovations:

1.Ultra-Efficient Source Capture Mechanism
By integrating a negative pressure suction nozzle at the end of the welding torch, a "fume capture barrier" is formed using 12,000Pa high vacuum. Fumes are inhaled into the pipe within 0.1 seconds of generation, with a measured capture efficiency of 99.2%. Third-party testing shows that PM2.5 concentration in the welding area drops to 15μg/m³, meeting national standards.

2.Zero-Interference Design for Welding Processes
The equipment uses side-flow negative pressure technology with an air suction volume controlled at 18–22m³/h. This avoids dispersing the welding shielding gas (such as argon) while ensuring no pores, cracks, or other defects in weld formation. Destructive testing confirms 100% qualification rate for welding joint tensile strength.

3.Flexible Architecture for Full-Model Adaptability
The 30mm slender air duct can swing 360° with robotic arms, adapting to 6-axis robots. Even in narrow pipeline welding scenarios, it can be quickly installed via magnetic suction interfaces, reducing equipment modification cycles to 4 hours.

The evaluation of high vacuum fume extraction

After the installation of the advanced high vacuum fume extractor, the customer carefully examined the surface of the advanced this fume extraction unit as well as its related accessories to ensure there was no damage or missing parts before conducting functional tests. During the comprehensive check, no issues were found.
