Description
Technical field
A kind of pump is the utility model is related to, more particularly to a kind of pump labyrinth type combination sealing.
Background technology
Desulfurization pump, axial-flow pump can be applied to the pump of a variety of working conditions, axial-flow pump transport acid, alkaline clear liquid or material
Slurry；The various corrosive ore pulps of smelting industry；All kinds of diluted acids of sulfuric acid industry；All kinds of sewage of environmental protection industry (epi) etc..The pump it is not only corrosion-resistant but also
Wear-resistant, use range is quite varied.The chemical industry desulfurization pump that vague generalization industrial and commercial bank industry is commonly used, the medium pumped are starched for sulfuric acid
Liquid, with substantial amounts of ashes and fine particle PH3 ~ 4,60 DEG C ~ 70 DEG C of slurry temperature in slurries, pump uses mechanically-sealing apparatus,
Due to carrying substantial amounts of ashes and particle in slurries, in work is run, machine seals work and severe leakage was just produced less than 15 days pump,
Replacing need to be often shut down, maintenance is also very inconvenient, adds production cost again, the serious normal operation that have impact on production, lets out
Dew also result in the pollution of environment simultaneously, and axial-flow pump makes liquid along axis by the blade of spinning roller impeller to active force caused by liquid
Direction conveys, and can convey clear water, slight sewage, and typically using double-mechanical sealing, there is also reveal caused by poorly sealed to ask
Topic.
Therefore, be attempted to solve this problem, desulfurization pump seal use material and structure, make pump have do not reveal,
The advantages that wear-resistant, corrosion-resistant, while there is preferable non-stick, self excellent lubricity, while being both adapted to desulfurization pump
Axial-flow pump is also widely applied to, axial-flow pump pump pulls the plug, it is also desirable to good airproof performance, to prevent the seal of leak-stopping water, makes
It is short with middle maintenance time, reduce the leakage of slurries or water, environment is not contaminated.
Utility model content
Problem to be solved in the utility model is that pump is easier to generation severe leakage in work is run, and particularly brine pump needs
Often shut down and change, repair, there is provided a kind of pump labyrinth type combination sealing, good sealing effect, and simple, maintenance time is installed
It is short, it is greatly enhanced production efficiency and can be widely used for other salinization pumps.
In order to solve the above technical problems, the technical solution adopted in the utility model is：A kind of pump labyrinth type combination sealing,
It includes power transmission shaft, axle sleeve, it is characterised in that：Seal combination is equipped with the axle sleeve, is provided between the seal combination
Sealing ring, inlet opening is provided with the sealing ring；
The seal combination is at least two seal combinations, and the end face of seal one is provided with triangle tongue circle, with its group
The seal biend of conjunction is provided with triangle groove circle, and two seals tightly engage into seal combination；
The end of seal combination two is separately installed with internal gland, outer press cover.
Seal case is set with the seal combination.
The internal gland, outer press cover are fastened on seal case both sides respectively.
Preferably, the seal combination can be more than two seal combinations.
Preferably, the inside and outside face of the internal gland, outer press cover is respectively arranged with zero type sealing ring.
Filled preferably, the seal combination seal is carbon fiber and graphite to polytetrafluoro（PTFE）Composite makes
And fasten.
The utility model has the advantages and positive effects of：
1st, the utility model pump labyrinth type combination sealing is due to using seal combination convex, recessed for two seal triangles
Groove circle mesh combination structure, and the end of seal combination two is compressed with internal gland, outer press cover respectively, seal combination can be with two or three
Seal combination, quantity is by using the selected combination of size requirement, and good sealing effect, desulfurization pump and axial-flow pump application effect are good, extensively
It is general to be applicable various different pump classes.
2nd, the utility model pump is made of labyrinth type combination sealing using carbon fiber and graphite filling PTFE composite, and it has
Have the advantages that not reveal, be wear-resistant, corrosion-resistant, while also having good non-adhesion behavior, self excellent greasy property.Using fan
The sealing of palace formula curved surface, improve it is original use flat seal, sealing effectiveness is 10 times of mechanical seal, and install it is simple, when repairing
Between it is short, greatly improve production efficiency, reduce the leakage of slurries, it is not contaminated to be effectively protected environment.
