Abstract
The utility model relates to a water cooling structure of a magnetic fluid sealing device. The water cooling structure comprises a coaxial housing, a magnet, annular magnetic poles disposed on two sides of the magnet, a magnetic transmission shaft provided with annular grooves in an annular magnetic pole portion, cooling rings made of non-metallic materials, and a plurality of seal rings. Peripheries of the annular magnetic poles disposed on the two sides of the magnet are shaped as steps, with peripheral surfaces of small ends of the steps being disposed on the two sides of the magnet; the coaxial housing is provided with a water inlet and a water outlet in an area corresponding to two shaft shoulders; joints between large end peripheries of the annular magnetic poles on the two sides of the magnets and an inner cavity of the coaxial housing are provided with the seal rings; and the cooling rings are disposed on peripheral surfaces of the small ends of the annular magnetic poles on the two sides of the magnet and the joints between the cooling rings and the peripheral surfaces are provided with the seal rings. The water cooling structure of the magnetic fluid sealing device, firstly, enables cooling water to cool the annular magnetic poles on the two sides of the magnet directly, thereby having a reasonable structure and good cooling effect; and, secondly, saves a cooling water feed inlet and drainage outlet and corresponding auxiliary pipes , thereby having a simplified structure.
Description
Technical field:
The utility model relates to the seal arrangement of a kind of engineering element or parts, especially relates to a kind of water-cooling structure of magnetic fluid seal device.
Background technique:
In the prior art, by magnetic field with magnetic fluid be fixed in running shaft around, form the seal arrangement of on-mechanical contact, be widely used in the manufacturing mechanisms such as semiconductor solar cell and LED.This magnetic fluid seal device can seal vacuum, but its deficiency is, can not be high temperature resistant.This is because under hot environment, magnetic flow is known from experience slowly volatilization, and can significantly descend its working life, needs each magnetic pole is cooled off for this reason.So need to increase the cooling water pipeline of magnetic pole, impel become complicated, cost of pipeline to increase; Meanwhile, the profile of vacuum equipment also can increase thereupon, and the position of dress cold water pipe also regular meeting is subjected to various restrictions, therefore is being merely able to use under the situation of the less magnetic fluid seal device of volume, and the magnetic fluid seal device of original structure just is difficult to use.
The model utility content:
The purpose of this utility model be provide at the prior art deficiency a kind of rational in infrastructure, can effectively reduce the magnetic pole temperature, prolong the water-cooling structure of the magnetic fluid seal device in magnetic fluid working life.
The purpose of this utility model is to realize by following measure: a kind of water-cooling structure of magnetic fluid seal device, it comprises coaxial shell, magnet, be positioned at the annular magnetic pole of magnet both sides, the magnetic transmission shaft, the magnetic transmission shaft is positioned at the annular magnetic pole position and is provided with circular groove, it is characterized in that the air ring, the some seal rings that also have nonmetallic material to make; It is same step-like that the described annular magnetic pole outer rim that is positioned at the magnet both sides all is, the small end outer edge surface of step is positioned at the magnet both sides, two step-like shaft shoulder spacings are corresponding with the width of air ring, and described coaxial shell is provided with water inlet and osculum in the zone of corresponding two shaft shoulders; The big end outer rim of the annular magnetic pole of described magnet both sides and the inner chamber joining portion of coaxial shell are provided with seal ring, and air ring is positioned on the small end outer edge surface of annular magnetic pole of magnet both sides and its joining portion respectively is provided with seal ring.
Described coaxial shell inner chamber is provided with annular groove in the area segments of two step-like shaft shoulder spacings.
Compared with prior art, adopted the water-cooling structure of the magnetic fluid seal device that the utility model proposes, had following advantage: 1) cooling water directly cools off the annular magnetic pole of magnet both sides, and rational in infrastructure have a good cooling effect; 2) water-cooling structure is oversimplified, and has reduced cooling water mouth and drain opening and corresponding pipe arrangement, has reduced manufacture cost; 3) this structure also can be used in the bearing structure of the different sizes in two ends, the left and right sides.
