Description

Technical Field

[0001] The utility model relates to the field of air-conditioning impellers, in particular to an air-conditioning compressor impeller which is easy to fix. Background Art

[0002] The impeller refers to the wheel with moving blades, which is a component of the impulse turbine rotor, and can also refer to the wheel and the rotating blades installed on it. Impellers can be classified according to their shape and opening and closing conditions. Also known as the working wheel, it is the only element in a centrifugal compressor that can work on the airflow. The most important components on the rotor are generally composed of parts such as the wheel, wheel cover and blades.

[0003] The utility model patent with publication number CN 215444521 U in the prior art proposes an air-conditioning compressor impeller that is easy to fix. This solves the problem that traditional impellers are prone to shaking when impacted during use, which may cause the impeller to touch other components while rotating, causing damage to the impeller itself or other components, posing a safety hazard.

[0004] However, it does not have the ability to independently disassemble the impeller. When local blades in the impeller are damaged, the blades cannot be disassembled and replaced. The entire impeller needs to be replaced, which is troublesome and costly. At the same time, the overall installation structure of the impeller is complicated, which is not convenient in actual use and is more prone to damage. Therefore, we need to upgrade and transform the existing technology to overcome the existing problems and shortcomings. Utility Model Content

Three groups of mounting holes 6 are correspondingly opened on the fixing disc 2 and the mounting disc 3. Fixing bolts 7 are threadedly connected in the mounting holes 6.

[0027] Preferably, the installation component 5 includes an installation cover 51 and a spline block 54. The center of the installation cover 51 is rotatably provided with a bolt section 52, and positioning rods 53 are provided on both sides. A sealing cover 55 is arranged at the lower end of the spline block 54. The bolt section 52 is screwed into the threaded hole 41. The installation cover 51 is attached to the top of the connecting column 21. The spline block 54 and the sealing cover 55 are fixed on the drive shaft 4. A positioning hole 22 is opened at the upper end of the connecting column 21, and the positioning rod 53 is correspondingly inserted into the positioning hole 22. A spline hole 23 is provided at the bottom of the fixed disk 2, and the spline block 54 is correspondingly inserted into the spline hole 23;

[0028] The cooperation between the bolt section 52 and the threaded hole 41 facilitates fixing the installation cover 51 on the top of the connecting column 21. The installation cover 51 is connected to the connecting column 21 through the positioning hole 22 and the positioning rod 53. The drive shaft 4 is connected to the fixed disk 2 through the spline hole 23 and the spline block 54. Furthermore, the drive shaft 4 can be doubly fixedly connected to the impeller, facilitating stably driving the impeller to rotate. The operation is simple and it is convenient to disassemble, install and fix the impeller.

[0029] Preferably, a plurality of inner convex strips 34 are arranged on the inner wall of the outer sleeve 32, and a plurality of inner grooves 25 are arranged on the outer wall of the connecting column 21.

Rotate the bolt section 52 to screw it into the threaded hole 41 and press it against the outside of the installation cover 51. At this time, the whole impeller is connected to the drive shaft 4, and the impeller can be driven to rotate through the drive shaft 4. When disassembling, operate in the reverse way. It can effectively and quickly disassemble and install the impeller, avoiding problems such as being laborious to disassemble the impeller and being prone to rust and jamming. When a part of the blade 31 is damaged, the impeller can be first removed from the drive shaft 4, then the fixing bolt 7 is removed from the installation hole 6, and then the installation disk 3 is removed from the fixed disk 2 for replacement. The new installation disk 3 is inserted through the cooperation of the guiding column 33 and the guiding hole 24, and then fixed by screwing through the cooperation of the fixing bolt 7 and the installation hole 6. The operation is simple and convenient. The blade 31 can be independently disassembled and replaced, and the fixed disk 2 and the connecting column 21 can be retained for use.
