Basically when cutting with the laser the beam is focused on the material through the hole in the nozzle. This heats the material and melts it. A cutting gas, which flows co-axially through the nozzle, removes the molten material. CHARACTERISTICS: Plate thickness: 1 mm up to 25 mm Typical: 0.5 mm up to 20 mm KEY FEATURES: Laser light can be well focused ca. 0.2 mm Very high power density (some MW/cm2) High to medium cut quality (roughness) Low heat input
The thing used to pour petrol or gas into a car is called a fuel nozzle or gas pump nozzle.
The nozzle that the burner tubing connects to allows gas to enter into the burner. Also, the nozzle has a lever that allows you to control how much gas will flow into the burner.
The Wedco Nozzle is a CARB compliant spill-proof gas can nozzle. With the nozzle in place you can invert your gas can and it will not leak. Then simply push the nozzle lock and push the nozzle against the rim of the filling throat of the tank you're filling to start the flow of fuel. If you lift the nozzle away from the rim the flow stops.
Generally this happens because of the amount of gas flowing from the nozzle. The nozzle "trips" due to back pressure. When the tank is full, gas pushes back on the nozzle and it shuts off. If the amount of fuel coming out of the nozzle fills up the filler tube going to your tank it also will cause back pressure and shut off the nozzle.
The nozzle of a fuel pump is the part that you stick into the opening of your gas tank.
there is a nozzle in the side where you put gas aduh!
Ratio of the cross-sectional area for gas flow at the nozzle inlet to that at the throat.
Laser cutting works by directing the output of a high-power laser, by computer, at the material to be cut. The material then either melts, burns, vaporizes away, or is blown away by a jet of gas
It doesn't. It stops when the tank is full. Assuming you are asking why the gas nozzle shuts off when the tank is full, I am not an engineer but I would guess that there is some type of pressure sensor in the nozzle that reads back pressure coming from the neck of the vehicle fuel tank and when that pressure reaches a certain point, it shuts the nozzle off.
open gas flap, and remove gas cap, insert gas nozzle
