Regarding the application of environmental protection hoods, many people are unfamiliar. Let Xiaobian lead everyone to learn the results of the design rules of the gas hood: Many people are unfamiliar with the application of environmental hoods, let Xiaobian lead everyone. Let's learn about the results of the gas hood design guidelines:
FRP gas collecting hood 1. Sealing measures should be taken for the process and equipment for distributing dust or harmless gas, and the closed hood should be adopted as much as possible. When determining the inhalation date of the closed cover and the construction of the micro-wind speed, the negative pressure inside the cover should be averaged to avoid the escape of the purified product. To prevent excessive negative pressure on the distribution of dust and volatile purification sources.
2. When it is not possible or convenient to adopt the closed cover, the remaining open air collecting hoods can be selected according to the technical operation requirements and technical and economic conditions. The gas collection hood should be as close as possible or close to the harmless purification source, so that the purification material is confined to a small space, and the suction range is minimized to facilitate the collection and control of the purification.
3. The amount of exhaust air at the suction point should be determined according to the criteria for avoiding the dispersion of dust or harmless gas into the surrounding environment. The suction of the hood should utilize the static action of the purified air as much as possible.
4. The inhaled airflow that has been purified is not allowed to pass through the human breathing zone, and the design should be fully considered with the operator's status and flow range.
5. The configuration of the gas collecting hood should be inconsistent with the consumption process, and strive to not affect the process operation. Under the premise of ensuring performance, the stress map is simple in structure, expensive in cost, and convenient for installation and protection.
6. Avoid turbulence around the gas collecting hood, and try to prevent or weaken the influence of the interference airflow, the wind and the air supply on the inspiratory flow.
Flap Wheels with shaft are made of multiple abrasive sheets attached to a core for fabricating, deburring, cleaning, polishing, and finishing jobs in metalworking applications. The sheets wear away during jobs, constantly exposing fresh abrasive coating to provide an even finish. Each grit flap comes in contact with the work piece at a slightly different angle, which prevents scratches. Because abrasive flap wheels conform to the shape of the surface material, they are commonly used to finish complex shapes and tight contours on a work piece. Flap wheels attach to grinders, drills, impact wrenches,or handheld rotary tools. They are either pre-mounted on a central hub, or unmounted for attaching to a compatible arbor.
Suitable for grinding the inner hole and camber of all kinds of metal and non-metal materials, select the suitable size of flap wheel with shaft for grinding. Remove burrs, rust, metal (plastic) and other surface grinding, internal and outter surface grinding, the grinding before painting, etc.Polishing, deburring, and removal of pits, burrs, and scratches. Remove parting lines and provide a uniform scratch pattern on all metals. The 1/4 inch stem allows for easy mounting on a die grinder or right angle die grinder.
