Introduction and working principle of aquaculture fan

Summer is a hot season, and then the problem for farmers comes. Whether the cooling measures are in place will directly affect the vital interests of the farm. The problem of cooling in summer has always been a major problem for farmers. Cooling work can not be sloppy. A little carelessness can cause a lot of casualties. At present, the commonly used cooling measures are breeding fans. The following is an introduction to this equipment.

This equipment is currently a commonly used cooling measure on farms, especially large farms. It is to install a water curtain at one end of the shed and a fan at the other end. When the fan is running for ventilation, negative pressure will be formed in the shed, and the outside air will be cooled by the water curtain before entering the shed to achieve the purpose of cooling.

The breeding fan is a good cooling device, but it needs to be used together with the negative pressure fan, so that the cooling effect will be good. However, what factors will affect the performance of the water curtain fan? let's explain

The performance indicators of the equipment are mainly the water curtain efficiency and the static pressure difference before and after the water curtain. However, these two indicators not only reflect the cooling performance of the water curtain, but also reflect the rationality of the water curtain structure. The efficiency of a water curtain is a measure of the heat and mass exchange between air and water. These factors also affect the flow resistance of the air in the water curtain, that is, the static pressure difference before and after the water curtain. Therefore, these parameters need to be analyzed to improve the performance of the water curtain.

When the thickness, wave angle and wave height of the water curtain are fixed, the flow path of the air in the water curtain is fixed, and the boundary conditions of the air flow are determined. At this time, the airflow pattern inside the water curtain mainly depends on the air flow.
