The nitrogen generator is controlled by programmable controller, which realizes automatic control of the equipment. At the same time, the purity of nitrogen is monitored on-line and in real time by an intelligent oxygen meter, and the oxygen content exceeds the limit is automatically warned. The machine molecular sieve adopts multi-point compound automatic pressing device, which can realize ten years no pulverization of molecular sieve.
Nitrogen drying is an inert gas, not susceptible to temperature and pressure changes, resulting in high temperature and the risk of puncture. Nitrogen has low permeability in tires, which can keep tire pressure stable for a long time and increase vehicle safety. Increase the shock absorption effect of the car, concave and convex road surface, reduce vibration, smooth driving, low volume conductivity. When the car is running, the steering wheel is stable, the tire friction coefficient is small, the friction with the ground is reduced, and the fuel efficiency is improved by more than 10%. Ordinary compressed air contains oil, water, nitrogen, no oil and water, no corrosion, nitrogen can extend the life of the tire ring.
The psa nitrogen generator comprises a pair of adsorption towers connected in parallel; Main inlet valve, adsorption tower inlet valve; Product nitrogen outlet valve, adsorption tower product nitrogen outlet valve; Silencer, adsorption tower desorption outlet valve; Connect the pressure equalizing valve of the adsorption tower; A pressure equalizing control valve is set in the middle of the adsorption tower. The nitrogen reflux connected to the product nitrogen outlet master valve is also connected to the pressure equalizing valve connected to the adsorption tower through the adjustment valve. When desorption is carried out in the adsorption tower, medium purity nitrogen is increased to carry out pressure equalization operation in the adsorption tower, so as to improve the purity of nitrogen in subsequent adsorption operations. At the same time, reduce the proportion of air consumption, increase nitrogen production, reduce energy consumption. Shell for tubular electric heating components for external finned electric heating tube, the central cavity of the tubular shell form high pressure gas cavity, high pressure gas cavity has a gas inlet and gas exports, in high pressure gas cavity at both ends with annular limit the steps, electric heating tube heaters located in high pressure gas cavity, at both ends of the electric heating tube set respectively with sealed end cover, sealed at the ends of the electric heating tube end cover respectively with high pressure gas cavity at the ends of the annular limit match the steps, the ends of the electric heating tube electrode respectively extend to high pressure gas cavity. The special air heater for nitrogen making machine has the characteristics of good heating effect and high sealing degree.
