Recently, many people report that the forbidden fastening bolts at the fan bolts often fail, for some reason. This still happens often after I try to renovate myself. I can only ask for help from Hubei Shuangjian Blower Factory. Aiming at the problem of bolt failure that troubles fan customers, a technician from Hubei Shuangjian Blower Factory will give you a detailed analysis today:
According to the survey and statistics of Hubei Shuangjian Blower Factory, the formation sites of fan bolt failures are mainly concentrated in the hub, motor-side coupling and reducer-side coupling.
The structure of the bolt may not be well understood by some customers. The fan bolts produced by Hubei Shuangjian Blower Factory are mainly used to connect the motor, the drive shaft and the reducer, and play a role in transmitting torque. The coupling is a diaphragm type, and the diaphragm can be prevented from axial movement and radial movement by bolts to prevent the diaphragm from deforming and causing abnormal damage.
In the cold winter, the temperature in the north, especially in the northeast, is as low as minus tens of degrees, and the fan is easy to freeze. The most commonly used ice breaking method is to reverse the fan to melt the ice. The effect is good, but it is easy to cause failure such as bolt loosening and fracture. Because bolts are fan consumables, in addition to loosening, breakage occurs from time to time. According to the statistical data analysis of Hubei Shuangjian Blower Factory, it is found that the probability of bolt breakage during winter operation is significantly greater than in other months. According to comprehensive statistics, faults such as loosening and breaking of fan bolts occur in winter, and the probability of such faults is not high during long-term operation in summer, and even rarely occurs. Therefore, in the cold winter, the fan bolts also need to be carefully taken care of.
Care for fan bolts Hubei Shuangjian Blower Factory recommends the following aspects:
1. Strictly control the number of wind turbine reversals in winter according to the actual and icing conditions. Only the icing of the wind turbine needs to be completely deiced at one time, and it is not necessary to use it regularly.
2. Regular inspection and condition inspection of the fan. Professional technicians regularly and comprehensively inspect the fan, and find the loose bolts in a timely manner.
3. The entire maintenance process is carried out in strict accordance with the maintenance standards to ensure the quality of the maintenance, to ensure that the components of the fan are in a safe and reliable state, and to ensure the continuous and effective operation of the fan.
4. Increasing the brake is the most effective way to prevent bolts from loosening and breaking. We at Hubei Shuangjian Blower Factory recommend to use the mechanical brake of the shaft to force the rotating fan to make the fan start in a static state, which greatly reduces Powerful danger of over torque.
Although the bolt is a small joint of the fan, if it fails, the impact on the fan is also great. If it is not found and repaired in time, the fault will be further expanded, which may cause damage to the diaphragm, the transmission shaft, the impeller and other components, resulting in greater harm. Hubei Shuangjian Blower Factory recommends that in the cold winter, the maintenance and maintenance of the fan bolts should be strengthened.
