With the constant advancement of science and technology, new industries are emerging at an astonishing rate. One such industry that has shown explosive growth recently is the laser cutting machine industry. However, it has become increasingly urgent for this industry to have access to clean auxiliary gas that is completely free of water and oil.
In response to this need, our company has invested significant manpower and resources into developing a range of products that are specifically tailored to the laser cutting machine industry. By greatly reducing the daily costs associated with operating a laser cutting machine, our products ensure the safe use of this innovative technology. As a result, they have been warmly received by manufacturers and users alike, with the market displaying a great deal of enthusiasm for our offerings.
Our game-changing air compressor for laser cutting machines is a combination of several key components, including an oil-free air compressor, air storage tank, air dryer, and precision filter. By designing these elements to work seamlessly together and providing a worry-free, labor-saving solution with a small footprint that requires no installation, our product is easy to use and provides unparalleled convenience for laser cutting machine operators.
Product advantages:
(1) Lubricating oil is essential for traditional oil-operated air compressors and permanent magnet variable-frequency screw machines to ensure smooth operation. Despite the implementation of multiple filters, a small amount of oil and gas can still be present in the discharged gas. Over time, as wear and tear intensify, the oil pollution in the exhaust gas increases. However, replacing the expensive filter core that meets the required standards poses a challenge, and failure to do so can pose a serious threat to the laser cutting head's safety. When the laser cutting head becomes blurry or burnt out, most users are unable to replace it on their own and must rely on the laser cutting machine manufacturer for maintenance. This not only incurs higher costs but also disrupts the production and operation of the majority of users. It is crucial to address this issue effectively to ensure a smooth and efficient operation of laser cutting machines.
The laser cutting machine requires an oil-free air compressor to ensure the purity of the discharged gas. By utilizing an air dryer and precision filter, the moisture in the gas can be analyzed and discharged, resulting in a worry-free usage experience for the users.
The laser cutting machine industry is currently experiencing rapid development, particularly in the field of high power. As a result, there is a growing demand for advanced and precise laser cutting machines that require auxiliary gases with higher standards. To ensure optimal cutting effects and equipment safety, many customers opt for nitrogen as their auxiliary gas. However, the cost of utilizing nitrogen is relatively high compared to other alternatives. According to estimates, using compressed air instead of nitrogen can significantly reduce costs, with air costing only about one-fifth of nitrogen. By utilizing compressed air generated by an oil-free laser cutting integrated air compressor, users can recover the initial investment in the compressor in approximately six months. The benefits of this approach are quite evident and can greatly impact overall profitability.
Our company has recently made a significant breakthrough in the improvement of oil-free air compressors by tackling the common issue of failure in the connecting rod needle roller bearing. After extensive technical research, we have successfully developed and introduced a composite piston pin specifically designed for oil-free air compressors. By implementing this innovative solution, we have effectively minimized the transmission of high temperatures from the piston's top to the piston pin, leading to a remarkable extension in the service life of the needle bearing.
One of the remarkable advantages of our composite piston pin is its ability to operate without the need for regular greasing for up to 3 years under normal working conditions. This significant improvement not only saves maintenance time and costs but also ensures smooth and efficient operation of the air compressor for an extended period. We are proud to offer this cutting-edge technology to our customers, guaranteeing enhanced reliability and longevity for their oil-free air compressors.
Many users of the equipment fail to utilize their supporting air compressors in an efficient manner, resulting in full load or even overload. This, in turn, leads to an excessive consumption of grease in the piston pin. We've taken this into account and developed an external grease injection function for oil-free air compressors. This function now gives users the ability to add grease to their equipment in just a few minutes, thus making the process of maintenance much easier and less time-consuming.
How to maintain:
Unscrew the plug at the bottom of the cylinder corresponding to the position of the piston pin, gently turn the pulley, align the piston pin plug in the cylinder with the hole, and use a flat-blade screwdriver to turn off the piston pin plug. Check for lack of grease inside the piston pin.If there is a lack of grease, inject the syringe with grease we distributed into it, wipe off the spilled grease after completion, screw on the piston pin plug, and finally screw on the cylinder plug.This completes the work of adding grease. Users can make records according to the actual consumption of grease and predict the next time to add grease, so as to maximize the use effect of the air compressor and serve your production and life.
