Wuhan 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 manufactor 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

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. In particular, the fan blades are most severely worn, Sweeper fan manufactor 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

Sweeper fan manufactor The work starts before the fan is used. one Wuhan Sweeper fan manufactor Carefully read the fan operation instructions and product samples, and be familiar with and understand the fan specifications, forms, impeller rotation direction and air flow in and out direction; Check whether all parts of the fan are in good condition again, or they can be installed and used only after being repaired. 2. The fan must be installed with safety devices to prevent accidents, and installed and wired by professionals familiar with relevant safety requirements. 3. The air duct connecting the inlet and outlet of the fan has separate support, and it is not allowed to add the overlapping weight of the duct to the components of the fan; When installing the fan, pay attention to the horizontal position of the fan, and adjust the connection between the joint surface of the fan and the foundation and the air outlet pipe to make it coincide naturally. Forced connection is not allowed. four large Sweeper fan After the fan is installed, move the impeller by hand or lever to check whether it is too tight or rubbed, and whether there is any object that hinders the rotation. The test run can be carried out only when there is no abnormal phenomenon. The exposed part of the fan transmission device should be equipped with a protective cover (provided by the user). If the fan inlet is not connected, a protective screen or other installation device (provided by the user) should also be added. 5. The power distribution control box of the fan must match the corresponding fan (power, voltage, pneumatic mode, control mode, etc.). 6. The fan wiring should be made by a professional electrician, and the wiring must be correct and reliable. Especially, the wiring number at the electric control box should be consistent with the number on the fan terminal. The fan shell should be reliably grounded. The grounding must be reliable, and zero connection cannot be used instead of grounding. 7. After all fans are installed, check whether there are any left tool box sundries inside the fan

The wet electrostatic precipitator has been recognized by users due to many advantages in the process of application. It can remove dust and purify waste gas. It is an environmental protection equipment that can be used in a wide range of situations. What steps can we take when using this environmental protection equipment? today Sweeper fan manufactor Let's take a detailed look. 1. First, close the power switch of the wet electrostatic precipitator. When the power indicator is on, the local remote switch will be switched to the local position; 2. Press the fan start button, and then observe whether the fan of the wet electrostatic precipitator rotates correctly. After the fan rotates normally, normal dedusting operation can be started; 3、 large Sweeper fan After a period of time, if you need to clear and discharge the ash, you can press the ash cleaning button on the wet electrostatic precipitator; 4. Turn over the pulse valve to clear the ash, and the screw machine and ash discharge valve will also work together. The above is the whole content of the application process of the wet electrostatic precipitator. What we need to remind us here is that the equipment can be started only after the position is adjusted before it is used. During the dust removal process of the equipment, the humidification function can be started to keep the ground wet, so that the wet electrostatic precipitator can have a better application effect.

The wet electrostatic precipitator is mainly used to purify water vapor, odor, acid mist and other harmful substances in the exhaust gas discharged by the factory. As an air pollution control equipment, it has also been widely used. let's Sweeper fan manufactor Understand its system composition together. 1. Composition of wet electrostatic precipitator system. According to its working principle, the control system of wet electrostatic precipitator generally includes high pressure system, water treatment system, low pressure heating and hot air purging system, upper computer system, etc. 2. Design of wet electrostatic precipitator system. (1) large Sweeper fan High voltage system and wet electrostatic precipitator charge the dust through corona discharge of high voltage system. The charged dust reaches the dust collecting plate under the effect of electric field force, and then the dust is removed by regular scouring. (2) Wuhan large Sweeper fan Water treatment system. This system deals with the problem of secondary water pollution. It is mainly the water discharged after equipment spraying and flushing, which contains a lot of acid substances and fine particles. Direct discharge will cause secondary pollution. The recycling of water in the equipment consists of two steps: neutralization and acid removal, and separation of suspended solids, so that the sewage can be turned into industrial water suitable for spraying. (3) Heating system. The heating system includes insulator incubator heating, hot air purging heating, and the hot air purging system is composed of fan, butterfly valve and heater. When it starts actively, it starts in the order of fan, butterfly valve and heater. When actively closing, it shall be closed in reverse order. (4) Upper computer system. The selected upper computer system is an industrial control computer, and the network front-end computer is used to enable the system to have extraordinary data acquisition and processing capabilities, so as to meet the requirements of wet electrostatic precipitator for centralized management, decentralized control, energy conservation and emission reduction.
