[0002] Metal casting is a process of melting metal into a liquid meeting certain requirements, pouring it into a mold, and obtaining a casting with a predetermined shape, size, and performance after cooling, solidifying, and finishing processes. Since the casting blank is nearly formed, it achieves the purpose of avoiding or minimizing machining, reducing costs and time to a certain extent. Casting is one of the basic processes in modern mechanical manufacturing industry.

[0003] A pump is a machine that transports fluids or increases fluid pressure. It transfers the mechanical energy of the prime mover or other external energy to the liquid, increasing the energy of the liquid. The pump housing is made of metal casting. To ensure the sealing performance of the pump housing, a seal ring needs to be installed inside the pump housing. However, when installing the existing seal ring, it is prone to falling off. The main reason is that it is inconvenient to fix the pump housing during installation, which leads to the seal ring not being fully compressed, and thus the installed seal ring is likely to fall off.
