High altitude pressurization equipment has a great effect on alleviating plateau reaction and plateau sickness.
Aims to develop a portable altitude pressurization solution for personal short-term altitude activities.
Seeking to develop a portable device that can provide in-vehicle pressurization based on on-vehicle power supply without changing any vehicle structure or inexpensive sealing solution.
The general vehicle will be sealing test, one is for the body sheet metal welding quality of the body sealing test; the other is for the whole car sealing test.
The body-in-white is installed in the body of various functional parts and interior before the body of the various process holes blocked, the doors and windows sealed, to the body of the inflatable air leakage test to detect its sealing.
Body-in-white testing generally maintains the inside and outside of the car pressure 250 Pa differential pressure, the general air leakage in 6L/s.
The whole car testing generally maintains the inside and outside of the car pressure 250 Pa differential pressure, the general air leakage in the 40L/s.
Such as the above diagram pressurization program at least to be able to achieve a differential pressure of 20 kPa
The whole car in the maintenance of the 250 Pa differential pressure on the basis of the. The air leakage is 40L/s, so if you continue to increase the pressure difference, the air leakage will be even worse.
And according to the 40L/s leakage amount of general vehicle power can drive the inflatable pump can not provide. As follows Portable car inflatable pump Product diagram:
On the basis of not considering the body seal upgrade, the car pressurization program is not feasible; and considering the complexity and difficulty of upgrading the body seal and the effect of uneven, the program can be abandoned before there is no more experimental verification.
Looking for a tent or similar portable equipment to provide a high-pressure environment.
There are similar products, such as portable hyperbaric chamber series
After consulting the collapsible soft hyperbaric chamber without oxygen concentrator, the current price is about 12,000 yuan, with an oxygen concentrator in about 17,000 yuan, although a little more expensive to meet the needs of the niche is still acceptable.
In the absence of a broader demand or necessary premise, taking into account the cost of re-development and niche market, can give up according to the program re-development.
