Design Focus of air filter The design inside the air filter body is mainly the design of the flow channel, because the flow channel is one of the main factors affecting the flow characteristic. Channel design should pay attention to: 1) try to expand the air intake area of the imported runner to ensure that the air inlet runner area is 1.5 of the designed caliber area ~ 2 times; 2) the flow channel should be as short as possible. on the premise of satisfying the strength, try to move the guide plate closer to the air inlet. Short runner can also shorten the structure size. When designing die casting, the air filter body should minimize the cutting allowance of machining, usually at 0.5 ~ 1.5. Too much cutting allowance will increase the cost of materials and processing costs, and will also increase the price. This is because it is inevitable that there will be shrinkage holes and other bad phenomena in the die casting. the thickness of the dense metal layer is relatively thin, and too much cutting will destro

What kind of mask does the doctor bring? Try a gas mask!Respiratory organ protection equipment that only protects respiratory organs from harmful substances.It is mainly used in operating environments containing low concentrations of harmful gases and vapours.Only the absorbent or suction agent is installed in the filter box.Some filter boxes are also equipped with filter layers,Anti-aerosol at the same time.Some military gas masks,Mainly made of active carbon cloth,Or use water-resistant oil-resistant fabric as the outer layer,The glass fiber filter material is the inner layer,Polyurethane foam soaked in activated carbon is the bottom layer,Temporary protection can be provided in the event of a gas attack.The gas mask is a bionic work, inspired by the wild boar on the battlefield after another war.Chemical weapons were used at the time,But the wild boar was not found after the war,Therefore, a gas mask and a gas mask were created to imitate the shape of the boar's nose.Anti-virus masks can be d
