Detailed Description

The present application is described in further detail below in conjunction with figures 1-2.

The embodiment of the application discloses a booster rotor. Referring to fig. 1, the booster rotor includes a ring body 1 disposed on a rotating member, where the ring body 1 may be integrally formed with the rotating member, and may be detachably assembled on the rotating member, so that the rotating member may rotate while following the rotation of the rotating member to be sealed. Simultaneously the axis of rotating member and the axis of rotating member are not on same straight line, and then make the ring platform set up for rotating the cover is eccentric, and then can drive ring body 1 eccentric rotation when making rotating member rotate, and then make gland inner space because of rotating, and lead to the inner space to change, thereby can be with the liquid in the gland from one of them liquid channel out, inhale liquid (like eccentric cam pump principle, realization pumping effect) in another liquid channel, and the ring body 1 of this kind of eccentric design compares for traditional helical groove formula ring body 1, it has reduced the inside liquid cavity space that seals of invasion gland, thereby guarantee that liquid capacity can not be too low influence liquid lubrication and accuse temperature effect.

Meanwhile, in order to prevent the ring body 1 from eccentrically rotating, the rotating component is disturbed due to unbalanced gravity center, and then the rotating component is bent, a plurality of pressurizing grooves 2 are formed in the side wall of one side of the eccentric big end of the ring body 1, the pressurizing grooves can be axially arranged through the pump body and can also be axially arranged without the pump body, the pressurizing grooves 2 can adjust the gravity center of the ring body 1, the dynamic balance effect is further ensured, the pressurizing grooves 2 can accelerate the internal space to change like pulses, and the pumping pressure of the ring body 1 is further improved. The length of booster tank is less than the ring body in this embodiment, and then makes the booster tank not run through the pump body axial setting, and a plurality of booster tanks 2 are equidistant crisscross to be set up along ring body 1 circumference, and then make the liquid that flows out from the liquid passageway flow to medium side (medium ring one side) and atmosphere side (cold ring one side) respectively after the direction of booster tank 2 to guarantee that liquid can circulate to the cooling medium of both sides, thereby guarantee lubrication and the accuse temperature effect of liquid. Meanwhile, the number of the pressurizing grooves of the ring body 1 close to the atmosphere side is larger than the number of the pressurizing grooves 2 of the ring body 1 close to the medium side, so that liquid supplied to the atmosphere side is more than liquid supplied to the medium side, the atmosphere side pressure is larger than the medium side, a certain pressure can be generated on the moving ring of the medium side, and the moving ring of the medium side can meet the requirement of medium sealing with a certain pressure. And the groove depth of each pressurizing groove 2 is gradually increased along the direction close to the opening of the end face of the pressurizing groove, so that the bottom wall of the pressurizing groove 2 forms an inclined plane, and then liquid can be sent out to two sides in an inclined manner under the guiding effect of the pressurizing groove 2 after entering from the liquid inlet, so that the situation that the liquid at dead angles in a sealing cavity cannot circulate is reduced.

The implementation principle of the booster rotor wing is as follows: the axis of ring body and the axis of rotating member are not on same straight line, and then make the ring platform set up for rotating the cover is eccentric, and then can drive ring body 1 eccentric rotation when making rotating member rotate, and then make gland inner space because of rotating, and lead to the inner space change, thereby can be with the liquid in the gland from one of them liquid channel out, inhale liquid (like eccentric cam pump principle, realize the pumping effect) in another liquid channel, and the ring body 1 of this kind of eccentric design compares for traditional spiral groove formula pumping ring, it has reduced the inside liquid chamber space of sealing of invasion gland, thereby guarantee that liquid capacity can not the too low effect liquid lubrication and accuse temperature effect, thereby guarantee mechanical seal effect.
