Technical characteristics
1. Low energy consumption of equipment
Full load nitrogen production per hour, with a total energy consumption of less than 39kw/h.
2. Stable flow rate and controllable purity
The airflow is stable, and nitrogen can reach equilibrium pressure after being stored in the gas storage tank
Purity is controllable, and the nitrogen production process is controlled by the PSA operating program with various auxiliary controls added. The flow rate can be measured and adjusted as needed, and the purity accuracy is controlled within ± 1%.
Product model XRFD-0100S:
When the purity is set at 90%, the flow rate is about 100Nm3/h;
When the purity is set at 95%, the flow rate is about 60Nm3/h;
When the purity is set at 99%, the flow rate is about 30Nm3/h;
When the purity is set at 99.9%, the flow rate is about 10Nm3/h;
3.Fully covering the cutting needs of commonly used boards, equipped with up to 7 working modes
Carbon steel thick plate mode, carbon steel thin plate mode, aluminum alloy thick plate mode, aluminum alloy thin plate mode (burr free cutting process), stainless steel thick plate mode, stainless steel thin plate mode; According to the cutting needs of different materials, different working modes can be selected to meet different cutting effects; The auxiliary gas supply system can also serve as a gas source for air cutting of ultra-thick plates to meet the cutting needs of high-power laser ultra-thick plates.
4. Deoxidation, deburring, and slag removal
Perfectly solving the problems of stainless steel and carbon steel slagging and pipeline pollution in air cutting, as well as the problems of oxidation and low efficiency of thin carbon steel sections in oxygen cutting. 5. The overall safety factor of equipment operation is high
By using a delay solenoid valve, the impact of air (gas source) on the nitrogen generator is protected, and the nitrogen production efficiency of the nitrogen generator can be effectively adjusted;
There are various coefficient safety control instruments and meters such as pressure sensors, gas flow meters, and nitrogen purity analyzers installed on the gas supply pipeline to achieve the safe start stop and alarm functions of the entire nitrogen production equipment. The integration degree of the entire nitrogen production equipment configuration is very high.
