The difference between CO2 laser cutting machine and fiber laser cutting machine processing

As the mainstream, traditional laser cutting uses CO2 laser, which can stably cut carbon steel within 20mm, stainless steel within 10mm, and aluminum alloy below 8mm. Fiber lasers have obvious advantages when cutting thin plates within 4 mm. Due to the wavelength of solid lasers, they are of poor quality when cutting thick plates. Of …

Application of high pressure PSA nitrogen production in oil fields

With the development of the petroleum industry, oil reserves are declining year by year, and oil exploitation is becoming more and more difficult. However, nearly two-thirds of the crude oil is still blocked underground because it has not been harvested by the first exploitation. Nowadays, new methods and technologies have been explored, which is injecting …

N2、O2 generator molecular sieve anti-pulverization method—Compression

Why need compression ? For PSA nitrogen oxygen generators, effectively protect the key part, molecular sieve, is of critical importance. When molecular sieve is filled inside the adsorption towers,as molecular sieve gravity is downwards, while gas flow is upwards, which makes the gas flow blow molecular sieve from opposite direction, this may make molecular sieve …
