Abstract
The utility model discloses a mechanical sealing device used for a pump on a ship. The mechanical sealing device comprises a pump body (2), a sealed moving ring (4), a sealed stationary ring (5) and a retainer spring (6), wherein the pump body (2) is fixed on a gland (1); the sealed moving ring (4) is sleeved and circumferentially limited on the sleeve (3); the sealed stationary ring (5) is sleeved on the sleeve (3) and circumferentially limited on the gland (1); the retainer spring (6) is arranged between the sealed stationary ring (5) and the gland (1); the sealed stationary ring (5) is pressed and matched on the end surface of the sealed moving ring (4) by the retainer spring (6); and the pump body (2) is provided with a flushing device used for flushing the contact end surfaces of the sealed moving ring (4) and the sealed stationary ring (5). The mechanical sealing device used for the pump on the ship does not easily lead the mechanical sealing effect to be lost and effectively reduces the cost and manpower of equipment maintenance.
Description
Technical field
The utility model relates to a kind of mechanical seal device, specifically is the mechanical seal for pump device on a kind of naval vessel.
Background technique
At present in boat coastal ship and submarine field, sealing to marine pump has very high requirement, particularly require higher with sealability to the high load naval vessel, operated by rotary motion has mechanical seal device on the pump that the naval vessel is used, this mechanical seal device comprises the pump housing that is fixed on the gland, be socketed on the axle sleeve and circumferentially spacing on axle sleeve the sealing rotating ring, be socketed on the axle sleeve and circumferentially spacing on gland stationary seal ring, be located at stationary seal ring and the holddown spring between gland; Described stationary seal ring is force-fitted on the end face of sealing rotating ring through holddown spring.Sealing rotating ring in this structure rotates along with the rotation of pump shaft, and stationary seal ring forms the sealing flour milling with the sealing rotating ring and realizes pump inside and extraneous mechanical seal.
There is following shortcoming in the mechanical seal device of above prior art: because warship marine pump operating mode complexity; usually contain a large amount of solid particles in the sealing medium; as silt; impurity; crystal etc.; and submarine is when slipping into or emerge; pressure can be gradually or intermittent the variation; excursion is bigger; these solid particles can form on the sealing flour milling with the sealing rotating ring at stationary seal ring and deposit; particularly deposition is obvious especially when pump stops or starting; make sealing unreliable like this, poor stability makes mechanical seal lose efficacy easily; therefore need often to change the sealed member of mechanical seal device, increased equipment maintenance cost and manpower.
The model utility content
The technical problems to be solved in the utility model is that the mechanical seal for pump device on a kind of naval vessel that is difficult for making mechanical seal lose efficacy, effectively reduce equipment maintenance cost and manpower is provided.
The technical solution of the utility model is, mechanical seal for pump device on a kind of naval vessel with following structure is provided, comprise the pump housing that is fixed on the gland, socket and circumferentially spacing on axle sleeve the sealing rotating ring, be socketed on the axle sleeve and circumferentially spacing on gland stationary seal ring, be located at the holddown spring between stationary seal ring and the gland; Described stationary seal ring is force-fitted on the end face of sealing rotating ring through holddown spring; Also be provided with the Rinsing unit that contacts end face that is used to wash sealing rotating ring and stationary seal ring on the described pump housing.
Described Rinsing unit comprises the annular cover that is fixed on the gland, and the wall of described annular cover is provided with radially first through hole that is communicated with the flushing medium source, and the described pump housing is provided with second through hole that also is communicated with the first through hole coaxial line radially.
The axis elongation line of described first through hole is positioned at contacting on the end face of sealing rotating ring and stationary seal ring.
After adopting said structure, the utility model compared with prior art, have the following advantages: because the Rinsing unit that increases is the end face that contacts that is used to wash sealing rotating ring and stationary seal ring on the described pump housing, help flushing like this and be deposited on stationary seal ring and the solid particle that seals on the rotating ring formation sealing flour milling, so just make sealing reliable, good stability makes that mechanical seal is difficult for losing efficacy, therefore need not often to change the sealed member of mechanical seal device, reduced equipment maintenance cost and manpower.
As improvement, described Rinsing unit comprises the annular cover that is fixed on the gland, the wall of described annular cover is provided with radially first through hole that is communicated with the flushing medium source, the described pump housing is provided with and the first through hole coaxial line radially and second through hole that is communicated with, makes the medium that flows through Rinsing unit that good circulation be arranged.
As improvement, the axis elongation line of described first through hole is positioned at contacting on the end face of sealing rotating ring and stationary seal ring, guarantees to be flushed to the center that contacts end face that seals rotating ring and stationary seal ring from first through hole medium that comes out, to reach better developing result.
