How to improve the performance of the vortex air pump
source:Industry News release time:2021-08-03 Article author:Rosit Popular:Air band saw
In the future, it will develop in the direction of environmental protection. From the country to the people, the voice of environmental protection is getting higher and higher. Driven by the general environment, various companies develop high-efficiency energy-saving products and low-energy, low-noise environmental protection. -Type products will occupy a leading position in the future market. At present, some companies have used some simulated calculation software to simulate and calculate the flow field and strength of the fan, and then compared with the data obtained from the experiment, and found that its aerodynamic performance parameters can be obtained more quickly and accurately.
1. How to make a high-efficiency energy-saving vortex air pump can start from the following methods:
1. Design and make a reasonable blade profile to reduce the friction loss in the blade cascade and the eddy current loss in the wake.
2. Determine the appropriate number of blades and hub ratio to reduce the loss of secondary flow.
3. Reasonable design of the height clearance of the casing and the radial clearance of the impeller to reduce the loss of the annular surface.
4. Match a suitable high-efficiency motor to improve the efficiency of the whole machine.
5. Improve the design of the inlet collecting position of the air pump casing to improve the air flow at the inlet.
6. Improve and redesign the mesh cover of the outlet of the air pump to reduce the resistance of the outlet.
7. Improve the design of the fan blade and the motor bracket to make it play the role of diversion as much as possible.
8. Improve the test and inspection equipment in order to grasp the actual aerodynamic performance of the fan in time.
2. How to design and manufacture a low-noise vortex pump
Low-noise and environmentally-friendly vortex air pumps require reasonable design and selection of the blade profile, number of blades, radial clearance of the impeller and motor, but can also be solved by the following ways:
1. Improve the accuracy of dynamic balance to reduce part of the noise generated by the vibration of the whole machine;
2. The impeller and other parts are made of materials with certain sound absorption properties to reduce the radiated noise caused by the vibration of the blade itself;
3. Design and develop new low-noise blades based on the principles of bionics.
