Animal husbandry fan, also known as negative pressure fan, is a new type The fan belongs to the axial flow fan, and is mainly used for the negative pressure ventilation cooling project, which is called a negative pressure fan.

Livestock FansThe exhausted air causes the indoor air pressure to drop and the indoor air to become thinner. The animal husbandry is characterized by the formation of a negative pressure zone where air flows into the room due to the compensation of the air pressure difference. In the practical application of industrial plants, the animal husbandry is concentrated on one side of the plant, and the air inlet is arranged on the other side of the plant. Air is convected from the air inlet into the livestock fan. During this process, the doors and windows near the livestock fan remain closed, and the air is forced into the workshop by compensating the doors and windows on the inlet side. The air enters the workshop from the air inlet through the workshop in a straight line, and the workshop is discharged by the animal husbandry fan. Good ventilation and high ventilation rate. Through specific engineering design, ventilation speed and wind speed can be designed according to need. Any high heat, harmful gas, dust and smoke can be quickly discharged from the workshop, and any problem of poor ventilation can be solved once and for all. Ventilation is achieved within a few seconds of turning on the fan.

Introduction of animal husbandry features:

1.Exhaust ventilation: installed outside the shop window, generally using the downwind It is used in general chemical plants to remove malodorous gases from the outside air.

2.Use Wet curtains: used as a workshop in the hot summer months, no matter how hot your workshop is, the wet curtain livestock fan system can bring your workshop temperature down to 30 °C or so, and has a certain humidity.

Working with animal husbandry fans Principle, fans can be divided into three types.

(1) Centrifugal fan. The airflow enters the fan impeller in the axial direction and flows mainly in the radial direction. This type of fan is manufactured according to the principle of centrifugal action. Products include centrifugal fans. Centrifugal fans and centrifugal compressors.

(2) Axial flow fan. The airflow enters the fan impeller in the axial direction and generally flows along the axis on the cylindrical surface. Such fans include axial fans, axial fans and axial compressors.

(3) Rotate the fan. Rotor rotation is used to change the working volume of the air chamber. Common varieties are Roots blowers and rotary compressors.

Use of animal husbandry fans Matters:

1. When the fan bearing temperature is normal, it is less than 70°C.If it rises to70 °C, there should be an electronically controlled (will) alarm. At this point you should find out why. First check if the cooling water is normal? Is the bearing oil level normal?

2.Fan in If abnormalities are found during driving, parking, or operation, check them immediately.

3.Animal Fan The lubricant (fat) should be replaced after one month of initial operation.
