Abstract
The utility model relates to a novel mechanical seal structure of a double suction pump, which comprises a pump shaft, a double end face mechanical seal, a mechanical seal press cover, a mechanical seal, a mechanical seal stationary seal ring, an O-shaped sealing ring, a mechanical seal washing inlet/outlet pipeline and a double suction pump casing. The structure is characterized in that the double end face mechanical seal is installed on the double suction pump casing on two sides of the mechanical seal on the pump shaft, the mechanical seal stationary seal ring is installed in a sealing cavity of the double suction pump casing on the inner side of the mechanical seal, a stationary ring is fixed on the mechanical seal stationary seal ring and is connected with the pump shaft in matching mode through the O-shaped sealing ring, another stationary ring is fixed on the mechanical seal press cover on the outside, the mechanical seal washing inlet/outlet pipeline is arranged on the double suction pump casing, and a mechanical seal washing inlet pipeline is externally connected with a water source. The novel mechanical seal structure has the advantages of separating media conveyed by the double suction pump from the sealing cavity and utilizing normal temperature clean water from the external through the mechanical seal washing pipeline to wash the mechanical seal, so that the double suction pump can convey sewage containing a small amount of impurities and toxic, corrosive, volatile and gasified media and is wider in application and durable in use.
Description
Technical field
The utility model relates to a kind of new type double sucking pump mechanical seal structure.
Background technique
At present, what the mechanical seal of double suction pump was all adopted is the form of single mechanical end face seal, draws the mechanical seal rinsing pipeline by delivery side of pump high pressure place and washes mechanical seal.When medium temperature was higher, mechanical seal moved under high temperature condition all the time, and obviously reduce working life; If when the medium of carrying contain a small amount of foreign material, poisonous, when the volatile easy gasification of burn into is arranged, double suction pump just has no idea to have used.Can stop up the mechanical seal rinsing pipeline because contain foreign material in the medium; Mechanical seal directly can reduce its life-span greatly with mordant medium contact; Medium poisonous, volatile easy gasification can not directly be used for washing mechanical seal, makes double suction pump that very big use limitation arranged.
Summary of the invention
The purpose of the utility model is to solve in the existing technology to wash the existing the problems referred to above of mechanical seal because employing is drawn the mechanical seal rinsing pipeline by delivery side of pump high pressure place, and a kind of new structure double suction pump that adopts double mechanical seal is provided.The utility model designs a kind of new type double sucking pump mechanical seal structure; Comprise that pump shaft, double mechanical seal, mechanical seal cover, mechanical seal, mechanical sealing static ring seat, O-ring seals, mechanical seal rinsing advance/go out pipeline, double suction pump housing; It is characterized in that: on the double suction pump housing of the both sides of the mechanical seal on the pump shaft, double mechanical seal is installed; In the Seal cage of the inboard double suction pump housing of mechanical seal, the mechanical sealing static ring seat is installed; Be fixed with stationary ring on the mechanical sealing static ring seat, stationary ring is by the O-ring seals pump shaft that is connected, and the mechanical seal cover in the outside is fixed with another stationary ring; On the double suction pump housing, offer mechanical seal rinsing and advance/go out pipeline, the external water source of mechanical seal rinsing inlet pipe.The utility model has the advantages that the medium and the Seal cage of the conveying of double suction pump pump are kept apart; Quote the normal temperature clear water from the external world through the mechanical seal rinsing pipeline and wash mechanical seal; Like this double suction pump just can carry the sewage that contains a small amount of foreign material, poisonous, medium such as the volatile easy gasification of burn into is arranged, make the application of double suction pump more extensively with durable.
Description of drawings
Fig. 1 is the BPO double suction pump of original use single mechanical end face seal, and 11 is the mechanical seal rinsing pipeline among the figure, and 12 is the double suction pump pump case, and 13 are single mechanical end face seal, and 14 is mechanical seal cover.
Fig. 2 is the new structure BPO double suction pump of the double mechanical seal of the utility model.
Below in conjunction with accompanying drawing and construction embodiment the utility model is made detailed operation instruction.
Embodiment
Comprise among the figure that pump shaft 1, double mechanical seal 2, mechanical seal cover 3, mechanical sealing static ring seat 4, O-ring seals 5, mechanical seal rinsing advance/go out pipeline 6,7, double suction pump housing 8; It is characterized in that: on the double suction pump housing of the both sides of the mechanical seal on the pump shaft, double mechanical seal is installed; In the Seal cage of the inboard double suction pump housing of double mechanical seal, the mechanical sealing static ring seat is installed; Be fixed with stationary ring 9 on the mechanical sealing static ring seat; Stationary ring is by the O-ring seals pump shaft that is connected; Mechanical seal cover in the outside is fixed with another stationary ring 9, on the double suction pump housing, offers mechanical seal rinsing and advances/go out pipeline, the external water source of mechanical seal rinsing inlet pipe.
When pump is carried special media; Because the stationary ring in the double mechanical seal is by the O-ring seals pump shaft that is connected; Medium can not enter into Seal cage, because the sparge water of mechanical seal all is the normal temperature clear water of being quoted from the external world by the mechanical seal rinsing pipeline, has improved the working environment of Seal cage more simultaneously; The longer service life that makes mechanical seal makes that the application of double suction pump is more extensive.
