Abstract
The invention discloses a mechanical seal flushing structure, which comprises a spring seat, a lubricating nipple, an inner compensation ring and an outer compensation ring. The lubricating nipple is connected to a hole of a liquid seal outlet through an oil tube, the inner compensation ring and the outer compensation ring form a liquid seal cavity, and the lubricating nipple, the oil tube, the inner compensation ring and the outer compensation ring are respectively arranged on the spring seat. The mechanical seal flushing structure improves the flushing effect of the radial double-end-face mechanical seal with a small installing size, is simple in structure, easy to achieve and capable of enabling the seal end face to be cooled and lubricated well, and greatly improves the flushing effect of the mechanical seal.
Description
Technical field
The present invention relates to a kind of mechanical seal rinsing structure.
Background technique
In the PTA industry, top INSERTTYPE stirrer (like the thin film evaporator) seal shaft that has is less to installing space, for adapting to these characteristics of stirrer; The radial direction double end-face structure is adopted in mechanical seal more, does not have Seal cage, thereby saves axial space; Help sealing and install, yet, do not have Seal cage because axially installing space is little; The flushing of sealing does not reach desirable developing result, is that washing solution is difficult for being flushed to seal face, and does not reach desirable cooling, lubrication effect; The flushing mechanism that this just need be fit to the mechanical seal design of this kind pattern, thus reach desirable developing result.
Summary of the invention
The purpose of this invention is to provide a kind of mechanical seal rinsing structure.
The present invention for realizing the technological scheme that above-mentioned purpose adopted is: a kind of mechanical seal rinsing structure; Comprise spring seat, oil nozzle, oil pipe, interior compensated loop and external compensation ring; Said oil nozzle is connected in the hole of sealing liquid outlet through oil pipe; Compensated loop and external compensation ring are formed the sealing liquid chamber in said, and oil nozzle, oil pipe, interior compensated loop and external compensation ring are separately positioned on the spring seat.
Said spring seat is provided with sealing liquid inlet and sealing liquid outlet.
A kind of mechanical seal rinsing structure of the present invention; Improve the developing result of the less radial double mechanical seal of axial installation dimension, simple in structure, be easy to realize; Can make seal face cooled off preferably and lubricate, greatly improve the developing result of this kind pattern mechanical seal.
Description of drawings
Fig. 1 is the structural representation of a kind of mechanical seal rinsing structure of the present invention.
Fig. 2 is the partial sectional view of oil nozzle of the present invention.
Fig. 3 is the partial sectional view of oil pipe of the present invention.
Among the figure: 1, spring seat; 2, oil nozzle; 3, oil pipe; 4, interior compensated loop; 5, external compensation ring.
Embodiment
As shown in Figure 1, mechanical seal rinsing structure comprises spring seat 1, oil nozzle 2, oil pipe 3, interior compensated loop 4 and external compensation ring 5; Oil nozzle 2 is connected to through oil pipe 3 in the hole of sealing liquid outlet, and interior compensated loop 4 is formed the sealing liquid chamber with external compensation ring 5, and oil nozzle, oil pipe, interior compensated loop and external compensation ring are separately positioned on the spring seat; The sealing liquid inlet A of washing solution from spring seat 1 gets into the sealing liquid chamber of being made up of interior compensated loop 4 and external compensation ring combination 5, because the height of oil nozzle 3 exceeds seal face, bottom oil pipe 2 plays seal action; Washing solution can not directly flow out from the sealing liquid outlet; But will be after liquid level exceeds oil nozzle open upper end place thus mouth flow in the hole of sealing liquid outlet B, flow out through the sealing liquid outlet, thereby make washing solution be flushed to seal face; The effect of reach the seal face cooling, lubricating, thus developing result improved.
Claims (2)
1. mechanical seal rinsing structure; It is characterized in that: comprise spring seat, oil nozzle, oil pipe, interior compensated loop and external compensation ring; Said oil nozzle is connected in the hole of sealing liquid outlet through oil pipe; Compensated loop and external compensation ring are formed the sealing liquid chamber in said, and oil nozzle, oil pipe, interior compensated loop and external compensation ring are separately positioned on the spring seat.
