Description

Technical Field

[0001] The utility model relates to the technical field of sealing structures, in particular to a containerized mechanical sealing structure. Background Art

[0002] A pump is a machine that transports fluids or pressurizes fluids. It transfers the mechanical energy of the prime mover or other external energy to the liquid, increasing the energy of the liquid. Pumps are mainly used to transport liquids such as water, oil, acid and alkali liquids, emulsions, suspensions and liquid metals. They can also transport liquid-gas mixtures and liquids containing suspended solids.

[0003] Application number CN202223074268,9 discloses a containerized non-flushing water mechanical seal structure, in which a connecting circular plate is transversely added to the bottom of the channel tube, and internal threaded holes are longitudinally opened all around the top of the connecting circular plate, and the internal threaded holes of the connecting circular plate are longitudinally threaded with connecting bolts, and positioning holes are longitudinally opened between the internal threaded holes of the connecting circular plate. This containerized non-flushing water mechanical seal structure, after the connecting plug is inserted into the hole pre-opened at the corresponding position on the pump, releases the lower pressure rod. Driven by the extrusion spring, the conical extrusion head connected to the bottom of the lower pressure rod reaches the bottom of the inner cavity of the connecting plug, and squeezes the surrounding limit plates and reset springs, so that the clamping rod extends from the guide hole. In this way, the bolts installed at the connection between the pump and the sealing structure can be effectively prevented from breaking and loosening under long-term operation. When this application is used in practice, the sealing effect still has a lot of room for improvement. Utility Model Content
