Abstract
The utility model relates to a sealing ring for the gland of a slurry pump. The sealing ring for the gland of a slurry pump is characterized in that the inner side of an annular ring body made from polytetrafluoroethylene resins adding fiberglass, quartz sands and other material is provided with an annular inner groove whose depth is 0.2 mm to 2 mm. The upper and lower end surfaces of the annular ring nearby the internal and external sides are respectively provided with an annular platform and the lip mouth which is corresponding to the platform and bulges 5 DEG to 30 DEG. The utility model has the advantages of pressurization, temperature resistance, wear resistance, acid base resistance, and good sealing performance; the sealing ring for the gland of a slurry pump which is used for a long term does not deform; the service life is 5 times of the rubber sealing ring of the prior art; the utility model is especially suitable for gas fields under the environment of drilling.
Description
The utility model relates to the improvement product of a kind of slurry pump with gland ring (packing).
Present slurry pump gland ring all is to adopt the rubber material manufacturing, and its profile generally all is simple O shape.Because poor-performings such as wear-resisting, withstand voltage, the heatproof of rubber material, acid resistant alkali, in drilling environment such as oil gas field, use, working life is short, need often to change, general homemade gland ring mean lifetime is only about 40 hours, consumption is very big, has increased cost of production, has reduced working efficiency.
The purpose of this utility model is the shortcoming that exists at existing slurry pump gland ring, has proposed the gland ring of a kind of novel wear-resisting, withstand voltage, heatproof, acid resistant alkali.
The technical solution of the utility model is to adopt the polyflon material to add materials such as glass fibre, silica sand to make an annular ring, the inboard of this circle has one to be the inner groovy of 0.2～2mm deeply, one platform is arranged respectively on its upper and lower end face in the outer part and a lip that strengthens seal ring selfsealings effect is arranged in the inner part, this lip has 5 °～30 ° angles with respect to the platform projection.
The utility model is owing to adopted the new material manufacturing, at least be 5 times of existing rubber seal its working life, and can under ± 250 ° environment, use for a long time, it is withstand voltage, wear-resisting, acid-proof alkaline all is significantly improved, and is the update product of rubber seal.

Wherein: 1 inner groovy, 2 platforms, 3 lips
Embodiment of the present utility model below is described:
With the polyflon material is base-material, add materials such as glass fibre and silica sand, under 150 °～200 ° temperature, be hot pressed into an annular circle body, the inboard of this annular ring has one to be the annular recess 1 of 2mm deeply, in the upper and lower end face of annular ring one platform 3 is arranged in the outer part, one lip 2 with respect to 10 ° of platform projections is arranged in the inner part, to increase the selfsealings performance of annular ring.
Claims (2)
1, a kind of slurry pump gland ring, it is characterized in that at the inner side surface that adds the annular circle body of material such as glass fibre and silica sand with polyflon one annular inner groovy 1 being arranged, the inner outside has a ring-shaped platform 3 respectively and with respect to the lip 2 of platform projection on the upper and lower end face of annular ring.
2, seal ring according to claim 1 is characterized in that annular groove is 0.2mm～2mm deeply, and the projection angle of lip 2 is 5 °～30 °.
