Anti-explosion magnetic liquid filter

Abstract

The invention discloses an anti-explosion magnetic liquid filter. The anti-explosion magnetic liquid filter is provided with a mechanical seal washing pipeline, and is characterized by being provided with a filter shell, a filter cover, a magnetic core assembly and a filter screen assembly, wherein the magnetic core assembly comprises a bolt, a spring and a magnetic core; the filter screen assembly comprises a filter screen, a seal loop and a seal ring; a filter cavity is formed in the centre of the filter shell; the end part of the filter shell is in seal connection through the filter cover; a liquid inlet hole and a thread blind hole are sequentially formed in the centre of one end surface of the filter cover; a liquid inlet port is formed in one side of the filter cover, and a liquid outlet port is formed in the other side of the filter cover; a liquid outlet hole is formed in one side of the liquid inlet hole; the liquid inlet end of the liquid inlet hole is communicated with the liquid inlet port, and the liquid outlet end of the liquid inlet hole is communicated with the filter cavity; the liquid inlet end of the liquid outlet hole is communicated with the filter cavity, and the liquid outlet end of the liquid outlet hole is communicated with the liquid outlet port; the liquid outlet port of the filter cover is connected with the mechanical seal washing pipeline; a magnetic core is arranged in the filter cavity and strung in the bolt, the spring of the bolt is fixedly connected with the filter cover, the filter screen is sleeved outside the magnetic core, and the filter screen is in seal connection with the filter cover. The anti-explosion magnetic liquid filter has the advantages of being novel in structure, safe in running, and the like.

Description

technical field [0001] The invention relates to the technical field of test equipment, in particular to an explosion-proof magnetic liquid filter. Background technique [0002] At present, the high-temperature centrifugal pumps used in my country's petrochemical industry and electric power generation all use mechanical seals in the shaft sealing system. The service life of the mechanical seal is affected by the pumping medium. In the petrochemical industry, the pumping medium is mostly toxic, flammable, Explosive high-temperature and high-pressure medium, the medium contains various impurities such as particles, iron powder, and welding slag in the pipeline. The existence of these impurities in the liquid will seriously threaten the end face of the mechanical seal. Once the sealing surface is damaged, the medium in the pump will leak out of the pump, causing serious harm to personnel, equipment and the environment. In severe cases, it will cause system shutdown and affect t...

AI Technical Summary

Problems solved by technology

The existence of these impurities in the liquid will seriously threaten the end face of the mechanical seal. Once the sealing face is damaged, the medium in the pump will leak out of the pump, causing serious harm to personnel, equipment and the environment.

In severe cases, it will cause system shutdown and affect the safe, reliable and stable operation of equipment
