Abstract
The utility model discloses a multistage low-speed centrifugal blower, which comprises multistage impellers, and each stage of the impellers adopts a ternary impeller. As the impellers provided by the utility model adopt the impellers with the most advanced ternary flow theory at present, and the shape of the blades of the impeller is designed according to the vorticity distribution of fluid particles inside the impeller, the blower approximates the real flowing state of the air inside the impeller, resulting small flow loss and high thermodynamic efficiency. Compared with the prior similar multistage low-speed centrifugal blowers, the utility model can reduce the energy consumption by 2 to 10 percent.
Description
Technical field
The utility model relates to a kind of multistage low-speed centrifugal blower.
Background technique
Centrifugal blower is a kind of turbomachinery that is used for conveying gas, and impeller is the core part of centrifugal blower, is the key point of its complete machine performance quality.Gas is three-dimensional space motion at the mobile of impeller inside, present state-of-the-art Theory of Three-dimensional Flowing designing technique is also come out, but multistage low-speed centrifugal blower still adopts the impeller according to the mobile Design Theory of monobasic, be binary impeller (see figure 3), make that present multistage low-speed centrifugal blower efficiency is low, energy consumption is big.
The model utility content
The purpose of this utility model is to provide a kind of and can cuts down the consumption of energy, the multistage low-speed centrifugal blower of raising the efficiency.
This multistage low-speed centrifugal blower that the utility model provides comprises multi-stage impeller, and every grade is all adopted 3 d impeller.
The multistage low-speed centrifugal blower of the utility model adopts present state-of-the-art Theory of Three-dimensional Flowing design impeller, every grade of impeller all adopts 3 d impeller, the time of day that the moulding of its ternary twisted blade is flowed near the impeller internal gas more, flow losses are little, the thermodynamic efficiency height.The utility model is compared with existing similar multistage low-speed centrifugal blower, and energy consumption reduces by 2～10%.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is a ternary twisted blade structural representation.
Fig. 3 is the structural representation of impeller in the prior art multistage centrifugal blower.
Embodiment
The multistage low-speed centrifugal blower of the utility model has intake grill 1, multi-stage impeller 2 as can be seen from Figure 1, and wherein every grade of impeller employing all is 3 d impellers.This impeller designs with at present existing state-of-the-art centrifugal impeller Theory of Three-dimensional Flowing, it is with the mobile inverse proposition formula of ternary, " whirlpool " (velocity circulation RCu) of input impeller inner fluid particle distributes, directly obtain ternary twisted blade type shape (as shown in Figure 2) by numerical calculation, compare with traditional monobasic flow design, near the mobile time of day of impeller internal gas, flow losses are little, the thermodynamic efficiency height more.During work, gas flows into the multi-stage impeller 2 that is made of the ternary twisted blade by intake grill 1, by these impeller 2 rotations, make gas be subjected to action of centrifugal force and produce pressure, meanwhile gas obtains speed, and gas stream is when expanding channel, and gas flow speed progressively slows down again and becomes the raising of gas pressure.
