Abstract
The utility model discloses a spindle seal structure of a direct-coupled centrifuge. The spindle seal structure comprises a spindle, an upper end cap and a lower end cap, the upper end cap and the lower end cap being sleeved on the spindle; the lower end face of the upper end cap and the upper end face of the lower end cap are provided with a plurality of projections and a plurality of grooves respectively, the projections being corresponding to the grooves in a one-to-one manner; an annular groove is disposed in the inner wall of the upper end cap along the radial direction; an O-shaped ring sleeved on the spindle is disposed in the annular groove; an upper framework seal ring and a lower framework seal ring sleeved on the spindle are disposed between the inner wall of the lower half portion of the lower end cap and the spindle; a space ring is disposed between the upper framework seal ring and the lower framework seal ring; and the upper framework seal ring, the lower framework seal ring and the space ring form a seal cavity which is filled with lubricating oil.
Description
Technical field
The utility model relates generally to direct connection centrifuge field, relates in particular to a kind of main shaft sealing construction of direct connection centrifuge.
Background technique
The main shaft seal of former direct connection centrifuge adopts end part seal circle and reinforced seal, in use, because material enters and causes seal failure, damages motor, and impact is produced.
The model utility content
The utility model purpose is exactly in order to remedy the defective of prior art, a kind of main shaft sealing construction of direct connection centrifuge to be provided.
The utility model is achieved through the following technical solutions:
The main shaft sealing construction of direct connection centrifuge, include main shaft, upper end cap, lower end cap, described upper end cap, lower end cap is sleeved on the main shaft, it is characterized in that: be respectively equipped with a plurality of one to one projections and groove on the lower end surface of described upper end cap and the upper-end surface of lower end cap, one or two annular grooves have radially been opened on the inwall of described upper end cap, be positioned at annular groove and be provided with an O type circle that is set on the main shaft, be provided with between the inwall of lower half portion of described lower end cap and the main shaft, lower two backbone sealing rings that are set on the main shaft, on, be provided with a spacer ring between lower two backbone sealing rings, on described, form a Seal cage between lower two backbone sealing rings and the spacer ring three, exuberant in the Seal cage have lubricant oil.
The groove number that establish the projection that establish the lower end surface of described upper end cap and the upper-end surface of lower end cap equates, the position is corresponding, and the protruding number that establish the groove that establish the lower end surface of upper end cap and the upper-end surface of lower end cap equates, the position is corresponding.
The utility model has the advantages that:
1. end cap forms labyrinth sealing up and down, stops solid material to enter seal ring;
2. O type circle stops liquid to infiltrate backbone sealing ring downwards along main shaft;
3. double backbone sealing ring stops liquid to be infiltrated by main shaft;
4. be full of lubricant oil in the Seal cage that backbone sealing ring and spacer ring form, guarantee lubricated and the infiltration of prevention liquid.
Description of drawings
Fig. 1 be the utility model together with centrifuge principal axis structural representation.
Fig. 2 is structural representation of the present utility model.
Embodiment
Such as Fig. 1, shown in 2, the main shaft sealing construction of direct connection centrifuge, include main shaft 6, upper end cap 1, lower end cap 3, upper end cap 1, lower end cap 3 is sleeved on the main shaft 6, be respectively equipped with a plurality of one to one projections and groove on the upper-end surface of the lower end surface of upper end cap 1 and lower end cap 3, one or two annular grooves have radially been opened on the inwall of upper end cap 1, be positioned at annular groove and be provided with an O type circle 2 that is set on the main shaft 6, be provided with between the inwall of lower half portion of lower end cap 3 and the main shaft 6, lower two backbone sealing rings 4 that are set on the main shaft 6, on, be provided with a spacer ring 5 between lower two backbone sealing rings 4, on, form a Seal cage 7 between lower two backbone sealing rings 4 and spacer ring 5 threes, exuberant in the Seal cage 7 have lubricant oil.
The groove number that establish the upper-end surface of the projection that establish the lower end surface of upper end cap 1 and lower end cap 3 equates, the position is corresponding, and the protruding number that establish the upper-end surface of the groove that establish the lower end surface of upper end cap 1 and lower end cap 3 equates, the position is corresponding.
Claims (2)
