Installation of exhaust pipe of lampblack machine:
Installation method: insert one end of the exhaust pipe into the slot between the inner and outer rings of the check valve outlet, and fasten it with screw. The other end extends outdoors directly through the reserved hole. If the exhaust pipe is connected to the public flue, it must be connected with the public flue anti-return smoke check valve and sealed well. If smoke is discharged outside the wall, it is recommended to install shutters outside the exhaust pipe to avoid backfilling. Smoke exhaust pipes are generally 15 cm in diameter and 18 cm in diameter, but now they are popular in the market are 15 cm. It's convenient to keep the opening small and expand it again. It's not difficult to change the opening large, but if the sealing is not good, it's easy to retell.
Jinan smoke exhaust pipe manufacturer explained the matters needing attention in the installation of smoke exhaust pipe of lampblack machine:
We need to check whether there is any condition for the ceiling to move downward so as to reserve space and position on the top of the pipeline. When pre-burying the exhaust pipe, attention should be paid to closing the gap of the flue outlet and ensuring that it does not fall off firmly. Before the ceiling, the smoke exhaust pipe of the smoke machine is embedded in the top of the ceiling. It is necessary to determine the position of the smoke exhaust pipe on the top of the ceiling according to the design drawings of the cabinet. The style of the smoke machine needs to be consulted. Generally speaking, the pipe of the European smoke machine is in the middle position, while the smoke exhaust pipe of the sergeant smoke machine is on the side of the smoke machine. If the smoke is exhausted to the common flue, do not insert the exhaust pipe too deep, which will increase the smoke resistance. If it leads outdoors, it is necessary to make the outlet of the exhaust pipe extend 75px. The exhaust pipe extends outdoors or enters the public cold-air suction flue. The interface should be tight, and the exhaust gas should not be allowed to be discharged into the hot flue. The shorter the pipe is, the better. If the pipe is pulled longer, then after turning off the hood, there will be a lot of smoke gathered in the pipe, which can not be exhausted, and then poured back into the room.
Installation requirements of exhaust pipe:
The distance from the exhaust outlet to the body should not be too long, and the turning radius should be as large as possible and less turning, otherwise the smoke exhaust effect will be affected. The exhaust pipe extends outdoors or enters the common cold air suction flue. The interface should be tight, and the exhaust gas need not be discharged into the hot flue. The outlet duct should not be too long, preferably not more than 2 meters, and minimize bending, avoid more than 90 degrees bending, otherwise it will affect the smoke absorption effect.
