Technical Field

[0001] The utility model relates to the technical field of pump seals, in particular to a pump seal which is easy to assemble and disassemble. Background Art

[0002] A water pump is a machine that transports liquids or pressurizes liquids. It transfers the mechanical energy of the prime mover or other external energy to the liquid, increasing the liquid's energy. It is mainly used to transport liquids including water, oil, acid and alkali liquids, emulsions, suspensions and liquid metals. It can also transport liquids, gas mixtures and liquids containing suspended solids. Water pumps are used in many fields, among which submersible pumps and semi-submersible pumps are widely used. If the water pump has a submersible function, the water pump needs to have good sealing properties. The sealing properties of the water pump play an extremely important role in good working performance. In traditional submersible pumps, waterproof seals need to be installed.

[0003] For example, a prior art Chinese utility model patent (CN207609600U) discloses a pump seal with a split structure that is easy to load and unload, comprising an annular main sealing plate, a left-mounted sealing connector provided on the left side of the main sealing plate, and a right-mounted sealing connector provided on the right side of the main sealing plate. The utility model discloses a pump seal with a split structure that is easy to load and unload, which utilizes a fixing bracket fixedly connected by bolts on the main sealing plate to connect the sealing connectors on the two side walls, utilizes a connecting rod with a fastening block on the inner end of the fixing bracket to be inserted into the sealing groove with a fastening groove on the sealing connector to improve the fastening performance, and greatly improves the sealing safety of the entire seal by connecting the inclined surface. The entire seal adopts a split design, is simple to load and unload, has a solid structure, and is very low in cost.
