What Kind Of Working Environment Is The Slat Type Inflation Shaft? What Gas Is It?

Analysis of the demand for periodic slat-type air-expansion shafts is often clean exhaust, exhaust gas treatment, or fire, ventilation, smoke exhaust, range hood, etc.

1. Normal Exhaust: The slat-type air-expansion shaft has no special requirements, as long as the design conditions and customer requirements are sufficient. But the slat-type air-expansion shaft is controlled at a general rotational speed of 1500 rpm, because the speed is too high, the slat-type inflatable shaft and the easily damaged parts, such as bearings and shafts, belts and pulleys, are prematurely worn, resulting in Maintenance costs for frequently replaced parts increase.

2. Exhaust process: Many types, some of which can contain slag, paint, explosive gas, sometimes resistant to hoods; different components have different treatment methods, different requirements for slat-type inflatable shafts.

1) Inserted in gas welding slag: cutting or welding equipment exhaust gas, usually considered slag and metal shavings and other impurities contained in the exhaust gas; the filter is increased, the motor can not be built. If these impurities enter the slat-type air-expansion shaft, the accessories such as the belt may be worn from the head bearing, and the damage of the motor is serious, resulting in the motor being scrapped. First, it requires the addition of aluminum mesh filter efficiency (filtering particle size greater than one millimeter) and entering the motor to prevent chip external motors. 2) Gas contained in the coating: a slat-type inflation shaft that adds most of the filter to the motor, shaft seal, and an external motor; the coating contains volatile organic solvents, flammable, explosive gases If you encounter a fire, such as an electric spark may cause an explosion. Therefore, a slat type inflation shaft is required;

3) Exhaust gas containing explosive or explosive dust: slat-type inflatable shaft and must be equipped with a motor;

4) Corrosive gases in the exhaust: First, it is necessary to understand the corrosive gases, their composition, if acid-base type, FRP (material) or plastic material selection; if medium corrosive, optional materials; if weak The exhaust air or acid-base corrosive gas content is relatively low, the method can be achieved by performing the coating on the impeller purpose, the single layer coating is 10 micrometers, and the double coating layer can reach about 20 μm.

3. Fire ventilation: The slat-type air expansion shaft should be selected by the national fire certification.

4. Range hood: For non-stick coatings, the impeller and the type of inflatable shaft that can be easily cleaned to clean the droplets are collected.
