Description
Technical field
The present invention relates to a kind of sealing member, specifically a kind of sealing member being applied to impeller.
Background technology
At present, impeller is one of indispensable equipment of sewage treatment plant, has various media in sewage treatment plant
Sewage, the sewage of different medium can have different requirements to the sealing member of impeller, in existing impeller when impeller
Spring and the waste water of sealing member in sealing member, often occur, leads to the oxidized corrosion of spring, cause sealing member and plug-flow
Sealing between device reduces, and so that seal fails can not be normally worked, shortens the service life of sealing member, or even makes to push away
Stream device breaks down, and improves cost, existing sealing member also has the not good problem of resistance to elevated temperatures simultaneously.
Content of the invention
The purpose of the present invention is to overcome the sealing member spring that the sealing member in existing impeller exists to lead to waste water
Sealing property is low, seal durability is short, sealing member resistance to elevated temperatures is not good problem, provide a kind of capability and performance high,
Spring is not good with waste water, resistance to elevated temperatures, long service life, the good seal performance sealing member being applied to impeller.
Present invention solves the technical problem that the technical scheme taken is：
A kind of sealing member being applied to impeller, including seal pipe, dead ring, clip one, clip two and spring, its feature
It is：Annular seal space, draw-in groove are provided with described seal pipe, and are provided with sealing strip on sealing inside pipe wall, in seal pipe
It is provided with annular seal space, adds coolant in sealing intracavity, it is to avoid the service life of the temperature too high impact sealing member of impeller,
It is provided with multiple sealing strips on sealing inside pipe wall, improve the sealing property between seal pipe and impeller, described dead ring
It is arranged in draw-in groove, the sealing effectiveness between sealing member and impeller is improve by dead ring, described clip one is arranged on
On seal pipe one end close with dead ring, described clip two is arranged on the other end of seal pipe, at the two ends of seal pipe
It is respectively arranged with clip one, clip two, improve the capability and performance of sealing member by clip one, clip two, described clip one,
Fastening plates are provided with clip two, described both ends of the spring is separately positioned on clip one, in the fastening plates on clip two, by bullet
Spring is arranged on outside seal pipe, it is to avoid the waste water in spring and impeller, prevents the oxidized corrosion of spring, solves sealing
Part, because of the damaged sealing actual effect problem occurring of spring, extends the service life of sealing member further.
Described seal pipe is set to High-molecular rubber material.
Described dead ring is set to carbofrax material.
Described sealing strip is set to any one structure in V-arrangement, S-shaped or waveform.
The quantity of described clip one upper platen is equal with the quantity of clip two upper platen.
Described fastening plates are set to arcuate structure, and the quantity of clip one upper platen is set to 3-8.
Beneficial effect：The present invention is provided with annular seal space in seal pipe, adds coolant in sealing intracavity, it is to avoid impeller
Temperature too high impact sealing member service life, sealing inside pipe wall on be provided with multiple sealing strips, improve seal pipe with
Sealing property between impeller, is respectively arranged with clip one, clip two at the two ends of seal pipe, by clip one, clip two
Improve the capability and performance of sealing member, spring is arranged on outside seal pipe, it is to avoid the waste water in spring and impeller, prevent
The only oxidized corrosion of spring, solves the problems, such as the seal fails that sealing member occurs because of spring breaking down, extends close further
The service life of sealing.
