Agricultural and animal husbandry fans are important components of environmental control systems for large-scale livestock and poultry farming. , energy efficiency and stability, etc., more and more become the focus of users.

In practical applications, different farming processes and stages, different farming houses and different ventilation designs have different requirements for the environmental control system, which in turn leads to the selection and configuration of the fans. The difference.

Agriculture and animal husbandry, also known as negative pressure fan, is a new type of axial flow fan, which belongs to axial flow fan. Because it is mainly used for vacuum ventilation cooling engineering, it is called a negative pressure fan. The negative pressure ventilation cooling project has two meanings: ventilation and cooling. At the same time, the problem of ventilation cooling is solved. The negative pressure fan is also used in the fields of positive pressure water curtain environmental protection air conditioning, positive pressure air supply, positive pressure air supply and the like. The negative pressure fan has the characteristics of large volume, large air duct, large diameter of the blade, large displacement, low energy consumption, low rotation speed and low noise. The negative pressure fan is mainly divided into galvanized square type negative pressure fan and glass fiber reinforced type negative pressure fan from structural materials. The structure and technical parameters of the galvanized square square negative pressure fan on the market are basically the same.

During the cooling of the axial fan, the two principles of evaporative ventilation are used.

From the ventilation process, it is easy to see that the operation of the fan is actually a process of outdoor air entering the room, so there will be a negative pressure environment inside the room, so that the outdoor air flows through the porous and humid On the wet curtain surface, the overall temperature will decrease. Under normal circumstances, under the action of the fan, the greater the indoor and outdoor temperature difference, the more obvious the cooling effect will be. The addition of evaporation causes the cooling process to add humidification, and the effect is doubled.

During the operation of the axial fan, the dust in the air will fall on the machine. After a long time, it must be cleaned regularly. Electrical maintenance is the basis for ensuring the stability of agricultural and animal husbandry fans.
