Embodiment Construction

[0040] In order to better illustrate the purpose and advantages of the present invention, the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0041] Step 1, use wire cutting to process two impellers with the same blade shape, such as figure 2 shown. Considering that two pieces are overlapped, since the total number of blades is 14, the number of blades of a single impeller is 7. The outer diameter end of each blade protrudes about 2mm from the fixing end 5 for final fixing welding.

[0042] Step 2: Carry out EDM cutting on the two leaf shapes respectively to process gaps and joints.

[0043] Use electric spark cutting to cut a gap of 0.5mm between two adjacent blades (determined by the diameter of the swirler) 1, and then use electric spark cutting to cut off the unnecessary part of the blade 2 and the inner fixing frame 4, and the remaining connection at 3, such as image 3 shown.

[0044] Step 3, Orthog...

Abstract

The invention relates to a forming method of a rotatably overlaying swirler and belongs to the technical field of machining. The forming method is applicable to processing of swirlers enabling fuels and air to be fixed. Two impellers in the same blade shape are processed in a linear cutting method and are respectively subjected to spark cutting in blade shapes to process spaces and connection positions; each blade rotates in the orthogonal rotation mode in the anti-clockwise direction with the center line as the axis, and the two rotated impellers are correspondingly overlapped and horizontally rotate for 180 / n degrees with the center as the axis to lead the space between two adjacent blades to be identical; and the two impellers are fixedly welded to obtain the swirler. The forming method reduces requirements for processing technology, devices and processes, saves processing time and improves efficiency.

Description

technical field [0001] The invention relates to a rotatable and superimposed cyclone forming method, which is suitable for processing a cyclone for mixing fuel and air, and belongs to the technical field of mechanical processing. Background technique [0002] Air pollution and environmental protection are becoming more and more important points that people are paying more and more attention to. With the proposal of sustainable development, China has raised environmental protection to a certain level both politically and economically. In addition, many governments have enacted restrictive environmental regulations related to the operation of fossil fuel combustion systems as well as laws limiting pollutant emissions from gas turbine engines. Also, there are a number of powerful tax rates for companies operating environmentally friendly installations or transforming their existing systems. NO x Emissions are an important factor in the evaluation of fossil fuel combustion, si...
