（2） Precautions for normal operation of fan 1. If the flow is found to be too large, which does not meet the operating requirements, or less flow is required in a short time, the throttling device can be used to adjust to meet the operating requirements. 2. The sensitivity of thermometer and oil pointer shall be checked regularly. 3. In case of any abnormal phenomenon during the start-up, shutdown or operation of the fan, it shall be checked in time. 4. For minor faults found in the inspection, find out the causes in time and try to eliminate or deal with them. If minor faults cannot be eliminated or major faults are found, repair them immediately. 5. In addition to replacing the lubricating oil during each maintenance, the lubricating oil shall also be replaced regularly. Observe the oil level at ordinary times and replenish lubricating oil in time.

In order to avoid man-made faults and accidents caused by improper maintenance, prevent the occurrence of natural faults and accidents of fans and motors in all aspects, so as to give full play to the efficiency of equipment and extend the service life of equipment, therefore, the maintenance of fans must be strengthened. （1） Working system of fan maintenance The fan maintenance personnel must pay attention to the following points: 1. The fan can only be operated when the fan equipment is completely normal. 2. If the fan equipment starts after maintenance, pay attention to whether all parts of the fan are normal. 3. Regularly clean the dust, dirt, water and other impurities inside the fan and gas transmission pipeline, and check whether the impeller is worn and rusted, if any, repair and replace it in time. 4. Regularly replace the lubricating oil (recommended 3-6 months). It is recommended to add N46 (ISO VG46, 30) in summer and N32 (ISO VG32, 20) in winter. The oil level should be at 1/2 of the oil window. 5. Check the coupling and belt pulley regularly (3-6 months is recommended), and repair and replace them immediately if parts are worn or rusted. 6. The equipment shall not be repaired during operation.

major Wet dedusting equipment The reasons for failure caused by unstable operation are: improper temperature control of insulator box; The gas distributor grid is blocked, and the sediment electrode has too thick scale; Improper adjustment of water film; The oxygen content in the system exceeds the standard. ① Insufficient steam pressure and blocked steam pipeline may cause low temperature of insulator box. In the long run, the insulator surface temperature is low, and tar and dust particles accumulate, causing electric field short circuit. If the temperature of insulator box rises too fast, or the temperature changes violently during operation, the insulator will be cracked. ② Wet dedusting equipment Price If intermittent flushing cannot be carried out as required during operation, the tar accumulated on the sediment pipe wall is difficult to be thoroughly cleaned, which, accumulated over time, not only causes excessive resistance to equipment operation, but also leads to damage to the electric field. ③ During maintenance, the water film is not adjusted as required, the water film is uneven or not thick enough, and after putting into operation, the phenomenon described in fault (4) will occur. The above situation also occurs when the water film is damaged during operation. ④ The reason for the explosion of the electrostatic precipitator is that the oxygen content in the gas exceeds the standard, the mixed explosive gas is formed in the equipment and reaches the explosion limit, and the explosion occurs when encountering electric sparks.

According to the report data released by the Global Wind Energy Council, the new installed capacity of global wind power in 2014 was 51477MW, up 44% year on year, and the cumulative installed capacity exceeded the threshold of 50GW for the first time. All data set new world records. China's wind power industry has driven global growth. In 2014, China's new installed capacity of wind power was 23350500 kilowatts, 45.1% higher than that of the previous year, major Wet dedusting equipment The cumulative installed capacity has reached nearly 115 million kilowatts, of which the grid connected capacity is nearly 100 million kilowatts, accounting for 7% of the total installed power generation capacity. In addition to the strength of wind power itself, the recovery of the wind power industry has also contributed to the decline of coal prices. The decline of fuel costs has led to the profitability of most power enterprises hitting a new high in 2014, Wet dedusting equipment Price This can expand the scale of wind power construction and accelerate the payment of unit arrears. As a result, the performance of wind power equipment manufacturers was in full swing in 2014, the market concentration was further improved to the top eight complete machine enterprises, and China's wind power industry basically ended the situation of low price competition. The wind power industry generally believes that the wind power industry will enter a new normal of stable growth in the future. In the next five years, the annual new installed capacity may reach at least 20 million kilowatts, and there is still a bottleneck for developers to improve their profits.

Ji'an major Wet dedusting equipment 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、 Wet dedusting equipment 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
