Abstract

The invention relates to the technical field of seals for pumps, in particular to a seal for a pump with a split structure that is easy to assemble and disassemble. There is a right sealing connector on the surface. The seal of the present invention has a split structure and is easy to assemble and disassemble the pump seal by using a fixing bracket fixedly connected by bolts on the main sealing sheet to connect the sealing connectors on the two side walls, and using a connecting rod with a fastening block on the inner end of the fixing bracket to insert The sealing groove with the fastening groove on the sealing connector improves the fastening performance, and the sealing safety of the entire sealing element is greatly improved by connecting the inclined surface.

Description

technical field [0001] The invention relates to the technical field of pump seals, in particular to a pump seal with a split structure that is easy to assemble and disassemble. Background technique [0002] Water pumps used in many fields. Among them, submersible pumps and semi-submersible pumps are widely used. If the water pump has a submersible function, it needs to have good sealing characteristics. The sealing characteristics of the water pump play an extremely important role in good working performance. Among the traditional similar submersible pumps , most of them adopt the following two structural forms: one is to use an ordinary brushed DC motor to directly drive the impeller to rotate. This form has strict requirements on the overall sealing of the pump, so its sealing structure is complicated, which brings many disadvantages to the manufacturing process. The oil seal is used for sealing; the second is to use an ordinary brushed DC motor to drive a magnet to rotat...
