Abstract
The utility model provides a sealing ring of a sand suction pump, which comprises a circular ring-shaped basic sealing ring. The inner ring port of the basic sealing ring is a fastening ring positioned in a plane vertical to the plane of the pump shaft. At least one additional sealing ring integrally manufactured with the basic sealing ring and coaxial with the basic sealing ring is provided outside the basic sealing ring. The sealing lips of both the basic sealing ring and the additional sealing ring, which are arranged towards a sealing friction disk, are horn-shaped openings. In addition, the sealing lips of both the basic sealing ring and the additional sealing ring are different in height. Due to the arrangement of the fastening ring, the sealing ring is fixedly arranged between an impeller and the plummer block plane of a shaft shoulder, so that the problem that sands leak through a gap between a sealing ring and a pump shaft is thoroughly solved. In addition, due to the additional arrangement of the additional sealing ring, the sealing effect between the sealing lip of the sealing ring and the sealing friction disk is improved. Meanwhile, the sealing lips of both the basic sealing ring and the additional sealing ring are different in height. Therefore, the sealing effect of the sealing ring is further improved.
Description
Technical field
The utility model relates to a kind of seal ring, especially relates to a kind of sand suction pump seal ring.
Background technique
The anti-bearing of existing sand suction pump advances husky device; Just a common circular rubber seal is socketed in the axle journal of sand suction pump; Rely on this rubber seal that the constrictive force of axle journal is fixed on the axle journal, along with the wearing and tearing of rubber seal and aging, the constrictive force of its combination can be lost gradually; Make between axle journal and the rubber seal of sand suction pump the space to occur, cause into husky phenomenon; Simultaneously, the seal action of rubber seal is also only realized through one deck seal ring, along with the wearing and tearing of seal ring lip, into husky phenomenon also can occur at seal ring lip place.More than the sands that get into of two kinds of approach, quickened the wearing and tearing of oil sealing and bearing, greatly shortened the working life of oil sealing and bearing, increased the maintenance load and the user cost of sand suction pump, reduced the utilization efficiency of sand suction pump.
The patent No. is 200920036744.3 utility model patent; " the husky seal arrangement of a kind of leakproof " disclosed; This device provides the technological scheme that seal friction dish and rubber seal are used in combination; This scheme has alleviated to a certain extent advances husky situation, but still does not thoroughly solve the husky problem of advancing that aforementioned two kinds of approach cause.
The model utility content
Technical problem:, a kind of into husky sand suction pump seal ring that prevents is provided to the deficiency that above-described existing technology exists.
Technological scheme: the sand suction pump seal ring that the utility model provides; Comprise a circular basic seal ring; The inner ring mouth of this basic seal ring is the fastening ring of a circle plane perpendicular to pump shaft; In basic seal ring periphery, also be provided with at least one and manufacture one and the additional encryption seal coaxial with it with basic seal ring, basic seal ring and additional encryption seal are horn opening towards the seal lip of seal friction dish.
During installation; With the tubaeform lip of sand suction pump seal ring towards the seal friction dish that is installed on the sand suction pump end cap; Be enclosed within the sand suction pump seal ring on the axle journal of pump shaft, then, mounted impeller again; Be fixed on fastening ring between the plane, pillow block rank of the impeller and the shaft shoulder, the seal lip of basic seal ring and additional encryption seal is adjacent on the seal friction dish.
Make basic seal ring different with the height of the sealing lip of additional encryption seal; In other words; The seal lip of basic seal ring and additional encryption seal is arranged on the Different Plane; Can further improve the sealing dustproof effect, for example:, manufacture outside the seal lip that protrudes in the additional encryption seal with the seal lip of basic seal ring.
Beneficial effect: owing to adopted the technological scheme that fastening ring and additional encryption seal are set, the utility model has solved existing sand suction pump seal ring and has advanced husky problem from two aspects.At first, fastening ring closely is fixed between the shaft shoulder of impeller and pump shaft, does not exist between seal ring and the pump shaft to relatively rotate, and can or not wear out to make because of wearing and tearing occurs the gap between the two, has thoroughly solved the husky problem of the leakage that causes owing to gap between the two; On the other hand, the sealing effect between seal ring and the seal friction dish has been strengthened in the additional encryption seal of setting up; Secondly, the different heights of the seal lip of basic seal ring and additional encryption seal has further strengthened sealing effect.

Embodiment
Below in conjunction with embodiment and accompanying drawing the utility model is further described.
Referring to Fig. 1, Fig. 2, Fig. 3 and Fig. 4.
The sand suction pump seal ring of present embodiment; Comprise a circular basic seal ring 1; The inner ring mouth of this basic seal ring 1 is the fastening ring 2 of a circle plane perpendicular to pump shaft; In basic seal ring 1 periphery, also be provided with one and manufacture one and the additional encryption seal 3 coaxial with it with basic seal ring 1, basic seal ring 1 and additional encryption seal 3 are horn opening towards the seal lip of seal friction dish.In the present embodiment, the seal lip of basic seal ring 1 is higher than the seal lip of additional encryption seal 3, and like Fig. 3 and shown in Figure 4, promptly the seal lip of basic seal ring 1 protrudes in outside the seal lip of additional encryption seal 3.
Certainly, according to the technological scheme of the utility model, two or more additional encryption seal 3 can be set outside basic seal ring 1.
During installation; With the tubaeform lip of seal ring,, be enclosed within seal ring on the axle journal of pump shaft towards the seal friction dish that is installed on the sand suction pump end cap; Then; Mounted impeller is fixed on fastening ring 2 between the plane, pillow block rank of the impeller and the shaft shoulder again, and the seal lip of basic seal ring 1 and additional encryption seal 3 is adjacent on the seal friction dish.
The protection domain of the utility model patent is not limited to the concrete scheme of present embodiment; Every inner ring at seal ring that utilizes the utility model to provide is provided with fastening ring; And the technological scheme of additional encryption seal is set simultaneously; And carry out production, manufacturing, assembling, the usage behavior of sand suction pump seal ring, all fall within the protection domain of this patent.
