Brief introduction of treatment measures for resonance faults of agricultural and animal husbandry fans

2020-04-03

With the development of China's economy, industrial production and agricultural planting have also risen. In industries where good ventilation is required, agricultural and animal husbandry fans have become the norm for applications. As we mentioned earlier, the vibration fault treatment measures of the fan, then in this article we will talk about the treatment and prevention of the fan's pipeline resonance failure.

Pipeline resonance and inspection measures

The wind speed of the inlet and outlet pipes of the fan is very high, and the high-speed wind will disturb the pipeline and cause the pipeline to resonate.-Under normal circumstances, the inlet and outlet pipes of the fan are rigidly connected by the flange and the impeller shell. The vibration of the pipe will be transmitted to the shell, and the shell is usually connected to the bearing seat, and the vibration of the shell causes the vibration of the bearing seat. Cause the whole fan to vibrate. The preventive measures for such vibration are::

(1)Check the casing of the farming and animal husbandry fan, if the casing is cracked or worn and its corrosion is serious, it should be strengthened or replaced;

(2)Install a pipe shock absorber on the pipe section with obvious vibration,Make the pipe and fan casing flexible connection, reduce or buffer the vibration. Commonly used pipeline shock absorbers, such asKTXFlexible rubber joints, ie pipe shock absorbers,-Generally installed near the outlet end of the fan, the shock absorption effect is better. In addition, some pipeline compensators such as stuffed compensators and waveform compensators can also act as shock absorbers.;

(3)The outlet pipeline can be optimized if conditions permit,-Generally speaking, the elbows are more likely to disturb the pipeline and cause vibration, so the outlet section of the fan should have no less than5 mStraight section to reduce the loss of outlet resistance and achieve the purpose of smoothly conveying the medium;

(4)The inlet regulating valve should preferentially choose the leaf valve, which can achieve the even distribution of the medium conveyed in the pipeline when working, preventing the occurrence of severe vortex and vibration.

The troubleshooting measures for the resonance of the farming and animal husbandry fan pipes are introduced here first.
