Three blower discharge capacity of: (1) the amount of wind. From the formation conditions of the fluidized bed, where the blower is good, suitable cross-sectional rising wind speed is required. Within a certain range of wind speed, wind speed and the size and discharge capacity. Therefore, the air volume and the size of the unit area about ventilation. (2) pressure. Roots blower and air from the drum into the overflow valve lock to overcome the resistance of three, Roots blower Which is good, one is effective fluidized bed material layer resistance, and its value is equivalent to the weight per unit area of ??material powder ; the second is Ⅰ, Ⅱ room bulkhead below the resistance of the material layer (including the effects of iron slag, etc.); the third is gas-permeable layer and into the trachea of ??resistance. Practice has proved that the real effective air lock with the proportion of the total resistance of the material layer for wind pressure is small, therefore, Urumqi Roots blower, air lock pressure regardless of whether the requirements have changed, the selection of the fan for the air pressure has little effect. (3) The discharge capacity. Sectional area of ??the discharge capacity depends on the speed and feed stream flow through the like. Sectional area of ??the stream is readily determined by, according to the experimental study of institutes believe that the discharge capacity can be by the amount of material per unit area to estimate the inflatable. Clover Roots blower with low noise, high efficiency, easy to operate, maintenance-free advantages integrated use of performance is better than two leaf blower, manufacture of high precision, high efficiency leading domestic level;. Is the most efficient application The most extensive blower, throughout used in petrochemical, building materials, electricity, metallurgy, chemical fertilizer, mining, ports, textile, food, paper, aquaculture and wastewater treatment, environmental protection industry and other areas. Roots blower where good, Zhucheng East Han Machinery Co., Urumqi blower provided by Han Machinery Co., Ltd. Zhucheng East. Zhucheng East Han Machinery Co., Ltd. (www.dhlcfj.com) (www.dhlcfj.com) is an industry leader in Shandong Weifang, fans, ventilation equipment, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs.
