[0034] Please also refer to figure 1 and image 3 , as a specific embodiment of the split shell structure provided by the present invention, the opening of the sealing gap 11 is an outer opening 111 communicating with the outside of the housing 1
[0035] Specifically, the opening through which the sealing gap 11 communicates with the outside of the housing 1 is the outer opening 111 , and the direction in which the suction magnetic field gradually increases is from the outer opening 111 of the sealing gap 11 to the inside of the sealing gap 11 . During installation, two adjacent housings 1 can be spliced together first, and then the magnetic sealant can be injected from the outer opening 111 of the sealing gap 11 from the outside of the housings 1 .
[0036] Please also refer to figure 1 and image 3, as a specific embodiment of the split shell structure provided by the present invention, two adjacent housings 1 are respectively provided with magnets 2, and in the direct...

The invention provides a segmented shell structure, a magnetic liquid seal device and a shell seal method, and belongs to the field of seal devices. The segmented shell structure comprises at least two shells, the bonding faces of the two shells are mutually attached, and a seal gap is formed. A suction magnetic field is formed in the seal gap through magnets on the shells, and the suction magnetic field is gradually intensified in the direction from an opening of the seal gap to the interior of the seal gap. According to the segmented shell structure, the suction magnetic field is utilized for sucking magnetic seal glue into the seal gap from the opening, and uniform distribution of the seal glue in the seal gap and the accurate shell position are guaranteed. The segmented magnetic liquidseal device adopts the above segmented shell structure, and the problems about shell dislocation and magnetic liquid leakage are solved. The shell seal method adopts the above segmented shell structure. The shells are spliced firstly, then, the suction magnetic field is utilized for sucking the magnetic seal glue into the seal gap, and the accurate shell position and sealing performance between the shells are guaranteed.
Description
technical field [0001] The invention belongs to the technical field of sealing devices, and more specifically relates to a split shell structure, a magnetic liquid sealing device and a shell sealing method. Background technique [0002] Magnetic liquid seals are widely used due to their advantages of zero leakage, long life, and low friction. The split-type magnetic sealing device is a sealing method in which the shell is assembled from multiple shells, and the inside of the shell is sealed with magnetic liquid. The split-type magnetic sealing device adopts a shell composed of multiple shells. When the magnetic liquid in the shell volatilizes, the bearing is damaged, etc., causing the seal to fail, the shell can be opened for maintenance. [0003] When installing the split magnetic sealing device, it is necessary to apply sealant in the sealing gap between the adjacent housings to ensure the sealing of the housings. In actual operation, it is necessary to apply sealant on ...
