large Sweeper fan Common fault: the working medium of the fan in the cement industry often contains a certain amount of homogeneous particles with different sizes and shapes, such as the induced draft fan of the dust removal system and the blower for pneumatic conveying. Because these fans work in the dusty air flow, the dust particles in the air flow will not only wear the fan, but also attach ash on the fan blades, and the wear and ash deposition are uneven. As a result, the balance of the fan rotor is destroyed, which causes the fan vibration and shortens the life of the fan. In serious cases, the fan can not work normally. Especially, the fan blades are worn most seriously, Sweeper fan Price It not only destroys the flow characteristics in the fan, but also easily leads to major accidents such as blade fracture and runaway. The wear of transmission parts is also a common problem of fans, including various shafts, rollers, reducers, motors, pumps and other bearing positions, bearing seats, keyways, threads and other parts. The traditional repair welding machine processing method is easy to cause material damage, resulting in deformation or fracture of parts, with greater limitations; Brush plating and spray re machining methods often require outsourcing, which not only requires long repair cycle and high cost, but also can not fundamentally solve the causes of wear (poor impact resistance and yield of metal) because the repair materials are metal materials; Many parts can only be scrapped and replaced, which greatly increases the production cost and inventory of spare parts, leaving the enterprise's good resource advantage idle and wasted

Ezhou large Sweeper fan Installation requirements a. The foundation of the fan shall be level and solid, and the foundation height shall be ≥ 200mm. b. The fan and air duct shall be connected by flexible hose (flexible material and non combustible), the length shall not be less than 200mm, and the pipe diameter shall be the same as the inlet and outlet size of the fan. In order to ensure that the hose will not be twisted or deformed during the system operation, it should be installed with appropriate tightness. The canvas hose installed at the suction end of the fan can be slightly tightened to prevent the fan from being sucked in during operation and reduce the sectional size of the canvas hose. c、 Sweeper fan Price The steel support of the fan must be fixed on the concrete foundation, and a rubber damping pad must be added between the steel support of the fan and the foundation. All fan and motor components are installed on the whole steel support, and the steel ground frame is installed on the damping pad at the top of the foundation. The damping pad is preferably made of perforated rubber plates. d. The pipe diameter at the outlet of the fan can only be increased, but not decreased. At the end of the outlet, an insect screen should be installed. When the fan is inclined to the upper outlet, a rain cap should be added

Forecast from domestic market capacity. Ezhou Sweeper fan Price Fans vary greatly according to different pressure and flow requirements. Therefore, the fan demand should be differentiated according to its type and size, and predicted according to the demand of different industries. According to incomplete statistics, the annual average growth rate of national fan output was 13.8% from 1980 to 1996. large Sweeper fan It is estimated that the total output of wind turbines in China will be 2.6 million to 2.9 million in 2005 and 3.1 million to 3.25 million in 2010. According to the statistics of fan industry over the years, it is predicted that the output of centrifugal compressors will be 1.6 million to 1.8 million in 2005 and 2 million to 2.1 million in 2010; The output of axial compressor is 260000 in 2005, and is expected to reach 360000 in 2010; The market share of turbine compressor and blower will reach about 70% in 2005

Dust leakage may occur when the wet electrostatic precipitator is used at ordinary times, so that the precipitator can not achieve the expected use effect when it is used Sweeper fan Price Let's specifically analyze the causes of dust leakage. 1. The dust remover is mainly assembled from the clean air chamber and the hopper. In this part, screws are used at the connection position between the upper box and the hopper. If the sealing strip used in this place is unqualified, dust will leak out. In addition to affecting the normal use of the equipment, the poor performance of the dust remover in use will have a great impact on the environment of the whole workshop and the surrounding environment. Even some wet electrostatic precipitators have a lot of materials with recycling value in the recycled dust. two Ezhou large Sweeper fan Improper filtering wind speed used in dedusting may also lead to dust leakage, because the dust will be adsorbed on the filter bag when the temperature is too high, so the resistance of dedusting equipment will increase when it is used, leading to leakage. 3. The dedusting bag is also a device that plays a major role in the operation and use of the equipment. If the density of the bag itself is relatively small, it may cause dust leakage to each other. Therefore, when selecting the bag, it is also necessary to select the one with better quality for use, and it is also necessary to do a good job of maintenance when using it again.
