Application: Automotive Manufacturing Drive Welding Robot
On the assembly line of automobile manufacturing, every precise swing of the welding robot is related to the structural strength and safety performance of the whole car. 0.1mm welding deviation may trigger a million recall risk; 0.01 seconds of air pressure fluctuation is enough to make the welded joints appear porosity, cracks and other fatal defects. In the face of such a production process that does not allow the slightest error, Dongguan Jubilee Compressor Parts Co., Ltd.'s brand ZAKF introduced 350HP frequency
Screw Air Compressor, is the ultimate stability of industrial-grade, to drive the welding robot's “precision power heart”.
Before the introduction of ZAKF's 350HP frequency
Screw Compressor to a German manufacturer of new energy vehicles, the welding shop was in a production dilemma due to unstable air supply. The traditional air compressor led to welding robot air pressure fluctuations of ±0.05MPa, welding gun attitude control is out of alignment, the defective rate of welded joints is as high as 12%, and the direct economic loss caused by rework is more than 8 million yuan per month. What's more, frequent equipment failures caused the production line to shut down for maintenance for up to 25 hours per month, severely limiting production capacity. Chen Gong, the technical director, recalled, “Welding is the core process of automobile manufacturing, and an unstable gas source is like a time bomb that can destroy our product quality and market reputation at any time.”
The arrival of the ZAKF 350HP frequency screw compressor turned the situation around. Its direct-drive design delivers 38m³/min of stable exhaust volume and 0.9MPa of constant pressure with a superb transmission efficiency of over 98%, building a rock-solid power foundation for welding robots. The carburized alloy rotor and cast iron body have been tested under 80,000 hours of severe working conditions, and can maintain zero-fault operation even in high-intensity continuous production, and the maintenance cycle has been extended to an astonishing 10,000 hours, which reduces the downtime of the workshop by 92%. The three-stage filtration device completely isolates impurities and oil in the compressed air with a nanometer precision of 0.01 μm, and with the intelligent interlocking system's ±1% accuracy monitoring of oil temperature and vibration, the defective rate of the solder joints has dropped to less than 2%. Mr. Chen said excitedly, “After the new air compressor was put into use, our welding pass rate increased to 99.8%, saving rework costs of more than 90 million yuan per year, and the production capacity was increased by 50%, so the competitiveness in the high-end car market has risen sharply.”
In the automotive manufacturing industry where competition is hot, ZAKF's 350HP frequency screw compressor redefines the quality of welding air source with performance that exceeds industry standards. Compared with frequency conversion models, its 15% lower energy loss not only cuts down the cost of electricity, but also provides pure power for laser welding, arc welding and other precision processes with ISO 8573-1 Class 0 air quality. Relying on 60,000 square meters of modern production base and more than 260 professional and technical team, Dongguan JOABE Compressor Accessories Co., Ltd. creates full-cycle air source solutions for global automobile manufacturers from equipment customization, installation and debugging to 7×24-hour after-sales response.
