Abstract
The utility model relates to sealing for a mechanical pump, in particular to sealing for a solid particle medium containing pump. A sealing device aims to solve the problem that material mixing is performed in existing mortar pumps, so that sealing leakage is severe and the sealing effect is poor. The sealing device for the solid particle medium containing pump comprises a pressing cover and further comprises a static ring, a rotating ring, an elastic element, a spring seat, a rotating ring auxiliary sealing ring, a static ring auxiliary sealing ring and an anti-rotating pin. The static ring is connected with the rotating ring, the elastic element is fixed on the spring seat and connected with the rotating ring, the rotating ring auxiliary sealing ring is sleeved with the rotating ring, the static ring auxiliary sealing ring is sleeved with the static ring, and the anti-rotating pin is fixed on the pressing cover. The sealing device is suitable for the mortar pumps.
Description
Technical field
The utility model relates to the sealing of machinery pump, particularly for the sealing with pump containing solid particle medium.
Background technique
The mortar pump of waste water processing station is material filling type sealing originally, and filler is tetrafluoro braid, and additional cooling water is lowered the temperature.In use, because lime particle and sand grains are comparatively serious to the wearing and tearing of tetrafluoro packing and pump shaft cover, there is Seepage after more than 20 hours in mortar pump, causes a large amount of mortar to leak.Repeatedly meticulously repair through professional and technical personnel, still cannot change this situation, the maintenance of average month at least twice, has greatly increased processing cost and the device maintenance cost of waste water.
Model utility content
The purpose of this utility model is to be that seal leak phenomenon is serious in order to solve existing mortar pump use condiment, the problem that sealing effect is poor.
For achieving the above object, it is a kind of for the seal arrangement containing solid particle medium pump that the utility model provides, comprise gland, also comprise stationary ring, rotating ring, elastic element, spring seat, rotating ring auxiliary seal ring, stationary ring auxiliary seal ring and stop pin, described stationary ring is connected with rotating ring, described elastic element is fixed on spring seat, described elastic element is connected with described rotating ring, described rotating ring is set on described rotating ring auxiliary seal ring, described stationary ring is set on described stationary ring auxiliary seal ring, described stop pin is fixed on described gland.
Further, also comprise Cock screw, described Cock screw is connected with spring seat.
Particularly, described stationary ring is teflon stationary ring.
Particularly, described stationary ring is graphite stationary ring.
Particularly, described rotating ring is cemented carbide rotating ring.
Particularly, described rotating ring is ceramic rotating ring.
Preferably, described rotating ring auxiliary seal ring is rectangle flexible graphite sealing ring.
Preferably, described stationary ring auxiliary seal ring is rectangle flexible graphite sealing ring.
Particularly, described elastic element comprises spring and thrust ring, and described spring is connected with described spring seat and thrust ring, and described thrust ring is connected with described rotating ring auxiliary seal ring.
The beneficial effects of the utility model are: provide a kind of and greatly improved the leakage of production process Raw for the seal arrangement for containing solid particle medium pump, improved Security and the manufacturing efficiency of producing.
Accompanying drawing explanation
Fig. 1 is embodiment's the structural representation for the seal arrangement containing solid particle medium pump.
Wherein, 1 is stationary ring, and 2 is rotating ring, and 3 is elastic element, and 4 is spring seat, and 5 is Cock screw, and 6 is rotating ring auxiliary seal ring, and 7 is stop pin, and 8 is stationary ring auxiliary seal ring, and 9 is gland.
Embodiment
Below in conjunction with drawings and Examples, the technical solution of the utility model is further described.
Of the present utility model for the seal arrangement with pump containing solid particle medium, comprise gland 9, stationary ring 1, also comprise rotating ring 2, elastic element 3, spring seat 4, rotating ring auxiliary seal ring 6, stationary ring auxiliary seal ring 8 and stop pin 7, stationary ring 1 is connected with rotating ring 2, elastic element 3 is fixed on spring seat 4, elastic element 3 is connected with rotating ring 2, rotating ring 2 is set on rotating ring auxiliary seal ring 6, stationary ring 1 is set on stationary ring auxiliary seal ring 8, and stop pin 7 is fixed on gland 9.
Embodiment
As shown in Figure 1, after this device is arranged on the shell of the pump that needs sealing, stationary ring 1 is close-connected with pump case, stationary ring 1 and rotating ring 2 are critical pieces of sealing device, stationary ring auxiliary seal ring 8 is arranged between stationary ring 1 and gland 9, and rotating ring auxiliary seal ring is arranged between rotating ring 2 and pump shaft.Spring seat 4 is for fixing elastic element 3, elastic element 3 comprises spring and thrust ring, spring passes to rotating ring auxiliary seal ring 6 by thrust ring by elastic force, and make stationary ring 1 and rotating ring 2 close contacts, thereby reach sealing purpose, stop pin 7 is fixed on gland 9 to prevent that stationary ring 1 from rotating.When work, stationary ring 1 is owing to being fixed on pump case, therefore do not move, rotating ring 2 together rotates with pump shaft.Between stationary ring 1 and rotating ring 2, form a seal face, for guaranteeing to make to keep necessary lubricating liquid film between seal face, the compressive load per unit area on the end face processed of necessary strict chamber, pressure is excessive, is difficult for forming stable lubricating liquid film, can accelerate the wearing and tearing of end face; Pressure is too small, and leakage rate increases.So will obtain good sealability has again enough life-spans, in the time of design and installation mechanical seal, must guarantee that end face compressive load per unit area value is in optimal scope.
