Description

Technical Field

[0001] The utility model relates to a compressor experimental device for associating the particle release point with the impeller wear position, in particular to a compressor experimental device for associating the particle release point with the impeller wear position, belonging to the technical field of compressor experiments. Background Technique

[0002] At present, diesel engines have been commonly selected as the power for medium and heavy-duty vehicles. A compressor is provided on the diesel engine to compress air through the compressor to increase the intake air volume of the engine, thereby improving its operating efficiency. Special vehicles using diesel engines will face operating conditions in high-sand environments in deserts, resulting in an increase in the sand content at the air inlet of the compressor. Since the impeller of the compressor is a high-speed rotating component, when sand and dust particles enter the impeller, it will cause wear problems on the impeller wall surface. Therefore, mastering the wear law of sand and dust particles on the compressor impeller is of great significance for proposing anti-wear designs and wear protection for the impeller and improving the operating life of diesel engines in dusty environments. For this reason, wear experiments on the impeller of the compressor are required.

[0003] In existing compressor impeller wear experiments, sand and dust particles are blown onto the impeller relatively evenly. However, when operating in a high-dust environment, sand and dust particles usually do not enter the impeller in a uniformly distributed form at the compressor inlet. When particles enter the impeller from different positions and at different angles at the inlet, the corresponding wear positions of the impeller will change, resulting in differences in anti-wear measures for different regions of the impeller. The existing experimental methods cannot adjust the position and angle of the particles entering the impeller, resulting in inefficient design of impeller wear protection.

Finally, the dust particles are blown onto the impeller of the compressor assembly 4 from the position of the second particle output pipeline 23. Then, the wear degree of the impeller on the compressor assembly 4 is obtained. Then, control the movement of the driving platform 32. At this time, the two first damping plates 39 on the third damping plate 314 clamp the third damping plate 314. The movement of the driving platform 32 will drive the third damping plate 314 and the first guide frame 317 to move, and drive the second particle output pipeline 23 to rotate through the sector gear disk 24, so as to adjust the angle of the second particle output pipeline 23 for blowing dust particles. Then, conduct the wear experiment on the impeller of the compressor assembly 4. After the angle of the second particle output pipeline 23 is reset, control the electric push rod 33 to extend, drive the gear 36 and the two bidirectional screws 37 to rotate through the first rack 35. The two first damping plates 39 corresponding to the third damping plate 314 move away from each other, while the two first damping plates 39 corresponding to the second damping plate 313 move closer to each other, so that the first damping plate 39 clamps and fixes the second damping plate 313. Then, the movement of the driving platform 32 can drive the first particle output pipeline 21 and the second particle output pipeline 23 to move through the second damping plate 313, the anti-slip sliding frame 311 and the support seat 312, so as to adjust the impact of the second particle output pipeline 23 on different positions of the impeller of the compressor assembly 4 with dust particles, and can adjust the angle of the second particle output pipeline 23 again for the experiment, so as to distinguish the wear areas and wear degrees of the impeller on the compressor assembly 4 caused by particles entering from different positions and at different angles. This device is convenient for subsequent arranging anti-wear measures with different degrees in different areas of the impeller on the compressor assembly 4.
