Attention should be paid to the operation of livestock fans

In breeding farms, livestock fans are essential equipment that ensures a good growth environment for livestock.. Well, the following small series to introduce the livestock fan operation needs to pay attention to details.

1. it is difficult to judge the cause quickly and correctly when the sound is abnormal in the operation of the livestock ventilator. Common from the bottom: suction tube suction solid impurities; livestock fan stator and into the friction; bearings are abnormal. At this time, often in the production of abnormal sound accompanied by vibration.

2., check the vibration and abnormal sound situation, the cause of severe vibration of livestock ventilator is difficult to intuitively judge, but also pay close attention to and sufficient inspection. Many types of vibration field: surge leads to mechanical vibration of fluid; animal husbandry fan and the original motivation for the vibration is not generated; livestock fan installation is not reasonable, bearing the abnormal situation; the G1 wheel is long run equilibrium cut ring vibration intensified; mechanical vibration caused by rotor or the contact point the situation and the gap between the stator. Judging the position of the bearing parts, see JB / T 8689 - 1, vibration inspection and limit value of "animal husbandry fan".

3. bearing inspection, bearing temperature measurement for understanding the work of bearings is very important, general provisions of uranium bearing temperature rise shall not be higher than the ambient temperature, milk house to wide. In addition, we should pay attention to the amount of lubricating oil and its pollution status, whether the sludge is parked or not, the oil temperature and the oil pressure are not given to the occasion. For the use of cooling water cooling livestock fan, should also pay attention to the amount of water cooling, water temperature. For the use of ring type oil lubricated bearing livestock fan, should also confirm whether the oil ring work properly.

4., the seal section of the inspection should be regularly checked, pumping part of the leak, the rest of the gap with the shaft or contact conditions, whether there is abnormal, abnormal sound and so on.

5. other parts of the inspection, pay attention to the air pressure, intake pressure, abnormal changes. Find out the abnormal situation in time, whether the air flow, current and so on.

The above is the details of the operation of the livestock fans, and we hope to be able to help you.
