Three blower discharge capacity of: (1) the amount of wind. From the formation conditions of the fluidized bed shows Fuzhou Roots blower, a suitable cross-section increased wind speed is required. Within a certain range of wind speeds sewage aeration blower, wind speed and 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, one efficient fluidized bed material layer resistance, and its value is equivalent to the weight per unit area of ??the material powder; Second Ⅰ, Ⅱ room spacer material layer below the resistance (including the effects of iron slag, etc.); the third is gas-permeable layer and into the trachea of ??resistance. Practice has proved 明罗茨 fan manufacturers wholesale, practical and effective air lock with the proportion of the total resistance of the material layer for wind pressure is small, and therefore, regardless of whether the requirements of the lock wind pressure changes, 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 where the blower is good, according to experimental research related institutes believe that the discharge capacity can be by the amount of material per unit area to estimate the inflatable. Roots blower advantages: 1. The fan noise, low vibration. 2. The impeller and shaft is integral structure, and impeller wear-free fan performance persistent, long-term continuous operation. 3. The high-speed high efficiency and very compact. The attached gear oil dumped oil installations, no leakage phenomenon. 5. No suction and exhaust pulsation, no buffer tank; 6. small footprint, ease of layout and installation where the blower is good, Zhucheng East Han Machinery Co., Ltd., Nanjing blower by the Zhucheng Eastern Han Machinery Limited. 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. John in Zhucheng East Machinery Co., Ltd. leadership with the staff warmly welcome all inquiries negotiations to create Zhucheng East Han Machinery Co., Ltd. a better future.
