Regeneration can be understood as the reverse process of adsorption; because when the molecular sieve completes a saturated adsorption, it cannot continue to adsorb gas, and its adsorption capacity needs to be "restored ", which is what we call "regeneration ".

PSA oxygen generators are also called molecular sieve pressure swing adsorption oxygen generators. The core part of the equipment is molecular sieves, a porous adsorbent; this adsorbent can work continuously for 6-8 years under normal use conditions, but if it encounters water or oil erosion, it will cause the molecular sieve s adsorption capacity to decrease, or even molecular sieve failure.

In simple terms, a medical central suction system is a negative pressure gas source, which consists of a vacuum pump, a vacuum tank, a sewage tank, a check valve, a vacuum solenoid valve, a sterilizing filter, a vacuum sterilization device and an intelligent control system, etc., to absorb and discharge medical waste gas and dirty liquid. Usually, the medical device used to extract gas, solids and liquids in the oral cavity that we see in dental clinics is a medical central suction system.

The so-called modular design is to split the oxygen production system into several parts (or modules). Different modules have independent functions and will work together according to a unified connection interface;

In the PSA oxygen production system, the material of the oxygen pipeline should be determined according to the oxygen pressure, temperature and laying method. In addition to providing certain strength conditions, the oxygen pipeline also needs to meet the requirements of corrosion resistance, rust resistance and fire resistance.

During the heating of the metal, a major difficulty is to prevent the workpiece from oxidation and decarburization (that is, the carbon content on the surface of the steel parts is reduced). This will affect the surface performance of the workpiece, resulting in unsatisfactory metal heat treatment results. The common solution is to place the metal under a protective atmosphere (such as nitrogen) to isolate the metal from oxygen before processing. The nitrogen used here needs to be of relatively

As a medium-to-large industrial equipment, VPSA oxygen production system will be very difficult to install and store, so there will be a series of requirements; one is to prevent equipment damage. The second is to ensure that the personal safety of the staff in the transportation and use links can be adequately guaranteed.

As an inert gas, nitrogen can effectively inhibit the growth of most microorganisms and prevent food from oxidation and deterioration, making it very suitable for food preservation. However, the nitrogen here must be high-concentration nitrogen. If the nitrogen concentration is not enough, it will not have the effect of food preservation. Of course, in addition to the quality of nitrogen, the barrier and sealing properties of packaging materials will also affect the shelf life.

One of the significant differences between the VPSA oxygen production system and the PSA oxygen production system is the use of a blower system; it replaces the traditional air compressor to provide air intake power for the entire equipment, which is a strong guarantee for the stable and efficient operation of the system.

Generally speaking, a complete set of medical gas systems consists of four parts: gas stations, gas transmission pipelines, monitoring and alarm devices, and gas terminals. There are two reasons for setting up a monitoring and alarm system. One is to track and monitor the data of each link in the production, transportation and use of medical gases, without missing any minor problems. The other is to sound an alarm to warn, and at the same time, pass accurate guidance information to management pe
