Description

Technical Field

[0001] The utility model relates to the technical field of ceramic pumps, in particular to a sealing structure between a wear-resistant plate and a shaft of a ceramic pump. Background Art

[0002] The pump body and pump cover of the ceramic pump are made of acid-resistant ceramics. Ceramic pumps for chemical industry are generally centrifugal pumps. Their impellers, volutes, shaft seal chambers, and suction and discharge pipes are all made of ceramics. They are suitable for conveying highly corrosive liquids such as hydrochloric acid, sulfuric acid, and nitric acid. The outer side of the shaft of the ceramic pump needs to be installed with a wear-resistant plate through a sealing structure to reduce shaft wear.

[0003] However, some sealing structures are mostly installed in a fixed manner, which makes it difficult to disassemble them conveniently, resulting in inconvenience in replacing density gaskets that have been excessively worn.

[0004] Therefore, those skilled in the art are in urgent need of designing a sealing structure between the wear-resistant plate and the shaft of a ceramic pump. Utility Model Content

During disassembly, the first bolt can be rotated so that the first bolt is threadedly connected and separated with the mounting frame and the fixing cylinder through the first threaded hole and the second threaded hole respectively, thereby losing the fixing effect on the mounting frame. The mounting frame can then be pulled out of the fixing cylinder to be disassembled, and the second mounting assembly can be disassembled similarly, thereby solving the problem that the sealing structure is mostly installed in a fixed manner, which makes it inconvenient to disassemble it more conveniently, and thus making it inconvenient to replace the density gasket after excessive wear.

When a first mounting assembly and a second mounting assembly are inserted into the interior of the fixed cylinder for installation, the positioning groove and the positioning strip can play a better positioning role, thereby facilitating better installation.

[0035] In some examples, the mounting frame is detachably structured by a first bolt and a fixing tube, and the first bolt is matched with a second threaded hole. When disassembling, the first bolt can be rotated so that the first bolt is threadedly connected with the mounting frame and the fixing tube through the first threaded hole and the second threaded hole respectively and then separated, so that the mounting frame loses its fixing function, and the mounting frame can be disassembled by pulling the mounting frame out of the fixing tube.
