Special vortex high-pressure blower for vacuum packaging equipment

exclusiveNSK/SKF bearings have superior rigidity and are more suitable for long-term non-stop operation. Two domestically produced machines can be used on top of one machine;The angled blade design allows us to have a larger airflow and higher wind pressure; The humanized independent fan blade connection plate allows you to avoid direct damage to the bearings even when extracting waste directly.

Detailed introduction to pressure and suction,Generally, they have the functions of blowing and sucking air, which means there is one mouth for blowing air and another mouth for sucking air.

The pressure of a fan refers to the kinetic energy per unit volume of gas passing through the outlet section of the fan, and correspondingly, the suction force of a fan refers to the kinetic energy per unit volume of gas flowing through the inlet section of the fan.

The strength of suction is related to the speed of air flow at the suction port. The faster the flow rate at the suction port, the greater the suction force. Conversely, the slower the flow rate at the suction port, the smaller the corresponding suction force.

When selecting, if you want the suction force of the air inlet to be large, you not only need to consider the pressure, but also the air volume, because the suction force comes from the flow velocity. If the size of the pipeline and air inlet remains unchanged, the suction force needs to be doubled That means the flow rate needs to be doubled, which means the air volume needs to be doubled; At the same time, as the flow rate and air volume increase, the pressure will also increase, increasing by a factor of square. The suction force needs to be doubled, and the pressure needs to be quadrupled.

Installation method
1. Use screws to firmly fix it to a horizontal and rigid foundation or base. The weight of the foundation is generally about three times that of the air supply fan as the standard. If the base is uneven, the machine may deform when the screws are tightened, and special attention should be paid - please install shock absorbers to reduce noise.
2. It is usually designed with the axis in a horizontal state. When the suction port is used in an upward or downward direction, the weight of the impeller and sub shaft is added to the bearing on one side, increasing the load and reducing the bearing life,
When the ventilation duct is not connected to the suction port, please install wire mesh to prevent the inhalation of dangerous or foreign objects.
4. The fully closed external fan cover and the open motor should be at least 20mm away from the wall.
