[0002] In various mechanical, chemical, metallurgical and pharmaceutical equipment, in order to prevent the leakage of liquids and gases, it is necessary to provide effective seals between the equipment interfaces, and the impeller shaft is usually sealed by mechanical seals or packing seals, and the sealing and buffering are achieved by filling auxiliary seals in the aluminum seal. The existing impeller seals are usually made by pouring aluminum liquid to achieve the complete production of a seal, but in the production process, the whole is generally cast, and after rough processing, it is cut into two halves by wire cutting, and then the mating surface is finely processed. There are too many overall casting defects, and the cost of the subsequent process is high. If one half is scrapped due to casting defects, the other will also be scrapped. This results in high parts cost, which is not conducive to mass production. Utility Model Content
