Escape respirator can be divided into filtering self-rescue respirators and chemical oxygen self-rescue respirators. The working time of air respirator is generally 30~360min. The protection time limit varies according to the type of respirator.
In general, the protection time of air respirators is slightly shorter than that of oxygen respirators.
1. Self-contained compressed air breathing protection device is only used to escape from dangerous gas. It shall not be used for fire fighting, entering anoxic or liquid cargo tanks, nor for firefighters.
2. The compressed gas cylinder of the escape breathing apparatus is equipped with a pressure gauge. During storage, the pressure gauge does not show the air source pressure.
3. The escape breathing apparatus is equipped with a flame-proof hood that can cover the head, neck and shoulders. There is a clear, wide and bright observation window on the hood.
4. Easy to operate, just open the hood on the cylinder valve without any additional action.
Car Spoiler
A car spoiler is a part similar to the inverted airplane tail that is installed on the trunk cover of a car.
Some cars have a front spoiler, commonly known as an air dam.
Some cars have side skirts on the upper side, which is also a kind of spoiler. On the other hand, its more important role is to effectively reduce the air resistance produced by the vehicle at high speed, which not only saves fuel, but also improves the stability of the vehicle.
The rear wing, that is, the car spoiler is not a simple decorative role, but to increase the grip and stability of the car at high speed, especially the car is not easy to tip over in corners, and can save fuel so how does it play this role? This requires us to first understand the aerodynamics of aircraft wing lift mechanism.
