Do the air compressor pressure increase and the molecular sieve operation occur simultaneously while driving?
When driving the vehicle, the boosting of the air compressor and the operation of the molecular sieve take place simultaneously, which is beneficial for the molecular sieve; there is no shock force, and the bed layer is not damaged. But some are not carried out simultaneously, yet the valves must be opened slowly. Proceed according to standard operating procedures*.
Whether synchronous or asynchronous, the boost rate must be well controlled; otherwise, the consequences can be severe
Can this thing sync? The air compressor pressure is below 0. 4. The water pump cannot be started. The temperature of the air entering the air-cooling tower is high, which can damage the plastic packing; therefore, the air-cooling tower doesn’t function properly
It’s best not to synchronize them. If it’s a turbine-driven compressor, that’s fine, but an electrically driven air compressor can raise the pressure to nearly 2 bar within 1 minute, which has a significant impact on the molecular sieve bed
I am relatively in favor of carrying it out simultaneously; using the purifier as a large \"buffer\" to regulate the voltage increase is a good option. As for concerns about high temperatures or issues with the packing, you can see clearly by observing the temperature rise of the air-cooled tower after pressure is applied but before water is introduced. Even if you fully open the guide vanes and turn off the air defense systems to increase pressure, it will not suddenly cause the airflow to impact the packing. Unless a butterfly valve suddenly opens wide, no other possibilities exist.
When starting up the air separation unit, it is better to increase the pressure of the air cooling tower, the air compressor, and the molecular sieve simultaneously; this allows the pressure in the system to rise as a whole, which is beneficial for the stable operation of the air compressor and helps avoid fluctuations resulting from two separate pressure increases. But it is necessary to control the pressure increase rate of the air compressor properly.
Reply 4# mauser makes a lot of sense
No, it’s possible to increase the pressure together with the cold-treated system; plastic fillers can also withstand high-temperature gases at 100°C. They’re not ordinary plastics, but rather high-temperature resistant polymers. However, for molecular sieves, higher temperatures result in a significantly higher saturated water content, which **increases the load on the molecular sieves – and that’s certainly not good for them.
I personally think it’s okay. Ours is a 1-to-2 setup, and the voltage must be increased together. The gas flow rate of the pressure-raising purifier is very low compared to normal conditions. Just make sure the voltage increase isn’t too fast.
The pressure can be increased together, which makes the system operation more stable; we often use this approach. However, the rate of pressure increase must be slow, and the pressure filling valve of the purification system should not be opened to a high degree
