Application industry:Automobile manufacturing industry
Under the trend of intelligent and refined production in the automobile manufacturing industry, from the body stamping and molding, painting and spraying, to the engine precision assembly, each link relies on stable, clean and high-flow compressed air. The stability of the air source directly affects the precision of equipment operation, product quality and production efficiency. ZAKF, a brand of Dongguan Jubilee Compressor Fittings Co., Ltd, has launched a 300HP frequency
Screw Compressor, which has become the first choice for many automobile manufacturers to upgrade their air source system due to its industrial-grade reliability and high-efficiency performance.
The intelligent factory of a leading domestic automobile brand in Chongqing mainly produces new energy vehicles and core components. Previously, the air compressor used in the factory had frequent fluctuations in air pressure and insufficient gas cleanliness, resulting in paint particle defects in the paint shop, a pass rate of only 88% in the body sealing test, and an annual cost of more than 12 million yuan due to rework. At the same time, frequent equipment failures led to a monthly downtime of up to 30 hours for maintenance, seriously affecting production capacity. Mr. Li, the head of the plant's power department, said, “The unstable air source has become a bottleneck that restricts production efficiency and product quality, and we urgently need a more reliable solution.”
With the introduction of
ZAKF 300 HP IF screw compressors at, the factory's production situation has taken a quantum leap forward. The direct-drive structure of the frequency motor delivers a stable output of 0.9MPa pressure and a high flow rate of 32m³/min with a transmission efficiency of more than 98%, which meets the needs of simultaneous operation of multiple presses and spraying robots. The carburized twin-screw rotor with full cast iron body has been operating without failure for more than 18 months in 24-hour continuous production, and the maintenance cycle has been extended to 8,000 hours, which reduces the downtime for maintenance by 90%. The three-stage air-water separator and nano-filter control the oil content of compressed air below 0.01mg/m³, the paint surface pass rate of the painting workshop is increased to 99.5%, and the pass rate of the sealing test of the body reaches 97%, which saves more than 10 million yuan in rework costs every year. Intelligent interlocking system monitors equipment parameters in real time, warns of abnormalities in advance, and avoids production interruptions caused by sudden failures. Mr. Li excitedly shared, “The new air compressor full-load operation efficiency is only 6.8kW/(m³/min), which saves more than 3 million yuan in electricity costs every year and improves production efficiency by 40%, giving us a greater advantage in the competition of new energy automobile market.”
