The rapid development of air filters is closely related to the development of military industry and electronic industry. In the first world war, the use of various chemical agents, asbestos fibre filter paper as the smoke filter layer of military gas masks came into being. The glass fiber filter medium is used in air filtration to obtain a patent in the United States in October 1940. In the 1950s, the United States studied the production process of glass fiber filter paper, and the air filter was improved and developed. In the 1960s, HEPA filters came out; In the 1970s, the filter paper of fine glass fiber was used as the HEPA filter of filter medium, and the filtration efficiency of particle size of 013 micron particle diameter was 99.9998%. Since the eighty s, with the emergence of new test method, use evaluation to improve and to improve the filtering performance requirements, found the HEPA filter there is a serious problem, and he had a higher ULPA filter performance. Countries are still working on it and expect more advanced air filters soon
The filter adopts high - strength wedge-shaped strainer to control the automatic cleaning of filter element through pressure differential control. When the impurity accumulates in the filter surface causes the import and export pressure difference to increase to the set value, or the timer reaches the preset time, the electric control box sends out the signal to drive the anti-flushing mechanism. When backwash suction dish and filter imports are pair, the drain valve is opened, the system pressure drainage, chuck and filter the inside a relative pressure below the filter of the lateral pressure of negative pressure zone, forcing some net circulating water from the inside filter lateral flow filter, adsorption on the inner wall of the filter in the impurity particles with flow into ç©£ disc and is discharged from the drain valve. The specially designed filter causes the inside of the filter to produce a jet effect, and any impurities will be washed away from the smooth inner wall. When the pressure difference of the filter is returned to normal or the timer set time is finished, the material does not break the flow during the whole process, and the anti-washing water consumption is low, which realizes the continuous and automatic production
A motor is an electrical machine which converts electrical energy into mechanical energy. When a current carrying conductor is placed in a magnetic field, the conductor experiences a mechanical force and this is the principle behind motoring action.
On the 458 Italia, the trucker can decouple the suspension damping from the electronic configuration selected about the manettino. The suspension decoupling button offers improved ?filtering? of uneven road surfaces as a way to improve performance and handling on uneven broken surfaces, for example the ones on the N?rburgring race track.
