What material is good for the oil fume exhaust pipeline?
1, in fact, PVC material is better for kitchen fume exhaust pipes. Because the melting temperature of PVC material is relatively stable between 185 ~ 205℃, the temperature of lampblack is far from this temperature. PVC material has high chemical stability, and can be used to make anticorrosive pipes, pipe fittings, oil pipelines, etc. PVC material can be said to be one of the largest plastic products in the world, and it is also a cheap and widely used product.
2. In the long run, it is best to lead it to the top of the range hood with 160 PVC pipe. Only when the range hood is working, the hose will keep shaking because of the wind. There is nothing wrong with the new air duct, but it may appear after a long time, and the shaking is enough to cause the air duct to rupture and leak oil. The PVC pipe does not have this problem, you can rest assured that it is sealed in the ceiling. Generally speaking, this material can be used for a lifetime. If you want to replace the air duct, you need to replace the section from the air duct base of the range hood to the PVC nozzle.
How large is the exhaust air volume of the range hood?
The exhaust air volume of range hood refers to the exhaust air volume per unit time when the static pressure value is zero. First of all, according to its conditions, the state stipulates that the index value is greater than or equal to 7m3/min. If people choose a larger exhaust air volume, they can quickly and timely suck out and discharge a large amount of oil fume in the kitchen. According to professionals, the exhaust air volume of general range hoods is 12~ 15 cubic meters, which is the best and can be said to be the most suitable. The ability to absorb lampblack mainly depends on how much negative pressure area the lampblack machine can produce in the area where lampblack is produced on the surface of the stove, and also depends on the exhaust volume, so as to see whether its exhaust efficiency is good or not, and also depends on the size of the wind pressure. Theoretically speaking, under the condition of reasonable turbine and inner cavity design, the greater the exhaust air volume, the greater the wind pressure of the range hood. So in a sense, the two are complementary and inseparable.
