Description

Fluid centrifugal through-flow action structure

Technical field

The invention relates to fluid action technology, in particular to a fluid centrifugal through-flow action structure.

Background technique

The flow of fluids (including air flow and liquid flow) needs the action of a fluid acting device to achieve it. According to different working fluids, the fluid action devices can be divided into two types: air flow fluid devices and liquid flow fluid devices. The practical application types of the air flow fluid drive device and the liquid flow fluid drive device are abundant, but the turbine type fluid drive device is typical and the most widely used. Turbine-type fluid drive devices are centered on axial-flow drive devices and centrifugal drive devices. Taking the driving air flow fluid device as an example, the driving air flow fluid device is divided into an air flow axial flow drive device and an air flow centrifugal drive device.

Axial flow fan is a typical air flow axial flow drive device, its advantages include: the inlet and outlet fluids are co-axial in the same direction, so the axial flow fan is easy to use in series in the air path; the axial fan exhaust port and fluid The inlet and the inner diameter of the air cylinder are generally large, the total wind resistance of the wind is relatively low, and the air volume is relatively large; the structure is simple, the manufacturing cost is low, and the maintenance is simple; the disadvantage is that the fluid delivery pressure is low, and the long-distance air supply is difficult. Restrict the application of axial fans.

The centrifugal fan is a typical air flow centrifugal drive device. Its advantages are high wind pressure, strong ability to overcome wind resistance, and long air supply distance. Its disadvantages include: long average air guide path, large wind resistance, and fluid movement The direction is orthogonal to the outflow direction, it is inconvenient to install and use in the air path, the transmission air pipe is a round pipe, and the exhaust side air pipe generally requires a square-circular conversion interface to achieve, which is not conducive to the optimal design of the air passage; the fluid inlet It is more difficult to make a large diameter, because the large-diameter fluid inlet will cause the size of the fan's outer profile to increase significantly; and the volume is too large.

From the perspective of the output air volume and pressure of the fan, there is a complementary relationship between the axial fan and the centrifugal fan, so people think of the advantages of combining the axial fan and the centrifugal fan, creating mixed flow (also known as diagonal flow) fans, circular duct fans and circular Centrifugal duct fan. Both the circular duct fan and the mixed flow fan are made of impellers made of twisted blades with meridional acceleration. The air intake part contains centrifugal air intake factors. The outflow mode is purely axial flow outflow, and the performance takes into account the large flow characteristics of axial flow fans. The wind pressure coefficient is higher than that of pure axial fans but smaller than that of pure centrifugal fans. However, the above fans only simply combine the advantages of the centrifugal fluid drive device and the axial fluid drive device, and there are some problems and defects. For example, the circular centrifugal duct fan belongs to the centrifugal air inlet and the axial flow outlet, and its axis The outflow of the flow mode simply relies on the semi-closed effect of the casing, so that the wind emitted from the centrifugal impeller has to be passively discharged from the outflow port, resulting in a reduction in the efficiency of the fan. In addition, the diameter of the inlet and outlet of the circular centrifugal duct fan is much smaller than the outer diameter of the casing, which makes it difficult to increase the working air volume of the fan and the radial size of the body is too large.

Similarly, the turbine-driven fluid flow fluid device and the air flow fluid device also have the above-mentioned problems. So far, there is a lack of a fluid action device that can perfectly combine the respective advantages of axial fluid drive and centrifugal fluid drive. The main reason is that the current centrifugal turbine fluid action device cannot be effectively solved. The problem of uniformly changing the direction of fluid flow and the direction in which fluid enters and exits the centrifugal turbine fluid action device is coaxial and co-directional.

Chinese patent CN104948502A discloses a centrifugal impeller deflector, but it has the following problems: on the one hand, its built-in deflector needs to be additionally installed on a fixed outer ring, and then the fixed outer ring is installed on the deflector Inside the casing, the installation is complicated and the cost is high, and once the deflector is damaged, it is not easy to replace; the fixed installation position of the motor is inside the outer cylinder. This deployment method on the one hand makes the motor installation occupy the outer cylinder can not be deployed A sufficiently long deflector, on the other hand, this structure can only limit the motor inside the outer cylinder, and the deployment flexibility is poor. In addition, the entrances and exits of this invention are all constriction openings, and this structure greatly affects the wind speed of the outflow.
