Description

Technical Field

[0001] The utility model relates to the technical field of impellers, and more specifically to a combined impeller with five blades in a group. Background Art

[0002] The impeller refers to the wheel disk equipped with moving blades, which is a component of the impulse steam turbine rotor, and can also refer to the general term for the wheel disk and the rotating blades installed on it.

[0003] Most of the existing impellers are made of titanium alloy, which has high mechanical strength and good impact resistance, but is heavy and has high requirements for magnetic bearing performance. In addition, the price of titanium alloy is high, which increases the production cost of the enterprise.

[0004] After searching, the Chinese patent with publication number CN113007132B discloses a combined three-dimensional flow impeller, which combines two impellers of different materials into one. The front end impeller is made of high-strength titanium alloy material, and the rear end impeller is made of high-strength aluminum alloy material. While ensuring the impact resistance and reliability of the impeller, the weight and manufacturing cost of the impeller are reduced. Furthermore, through the interference fit of the conical surface and the difference in thermal expansion coefficients of the two materials, it can be effectively ensured that the relative position of the front end impeller and the rear end impeller of the combined three-dimensional flow impeller will not change in the high temperature environment during operation, thereby ensuring the operating reliability and operating performance of the combined three-dimensional flow impeller.

[0005] However, in actual use, the impeller is processed by integrally casting a group of blades and blade discs, which is expensive. Moreover, when one of the impellers is damaged, it can only be replaced as a whole, which makes maintenance difficult and costly. Utility Model Content

[0010] By adopting the above technical solution: in order to facilitate the individual disassembly and replacement of the blades, the complexity and cost of maintenance are greatly reduced, and the number and arrangement of the blades can be adjusted according to actual use requirements to adapt to different working environments, thereby greatly improving practicality.

[0011] As a further description of the above technical solution: a threaded groove is provided on the surface of the mounting block, a bolt is arranged inside the threaded groove, one end of the bolt extends into the interior of the block, a mounting seat is threadedly connected to the bottom of the turntable, and support frames are arranged around the mounting seat.

[0012] By adopting the above technical solution: in order to improve the stability of the blades, so as to ensure their stability during high-speed rotation.

[0015] Technical effects and advantages of the utility model:

[0016] 1. By setting a disassembly mechanism, compared with the prior art, the card block is inserted into the card slot opened inside the mounting block, and the card column inside the card slot is also inserted into the card column slot opened inside the card block, so that the first magnetic block and the second magnetic block are magnetically connected, and then preliminary positioning is performed, and then the bolt is rotated downward to drive the bolt to rotate into the threaded groove opened inside the mounting block and the inside of the card block, so that the mounting block and the card block are fixed, so that the blades can be disassembled and replaced separately, which greatly reduces the complexity and cost of maintenance, and the device can also adjust the number and arrangement of the blades according to actual use requirements to adapt to different working environments;
