Degree change is big, some media are even there are certain volatility, and also with toxic, injury of these situations to people is big, caused by ring
Pollute also than more serious in border.
The feed liquid delivery pump that domestic various regions chemical enterprise uses is past due to unsuitable mechanically-sealing apparatus, pump main engine plants
Sealing device toward selection packing seal or bellows mechanical seal simple in structure as pump.Packing seal is because there is cost
Cheap, the host accuracy of manufacture requires low advantage, and bellows mechanical seal is because simple in structure, and handling ease is convenient, and cost is low
The advantage such as honest and clean.It is so widely used to pump producer everywhere for a long time.
In today that problem of environmental pollution is more prominent, the environmental requirement that relevant departments propose various enterprises is increasingly
It is high.But packing seal also has a variety of drawbacks：First, the sealing effect of packing seal is bad, and " run, drip, leak " phenomenon is long-term
In the presence of causing environmental pollution；Sylphon seal is due to simple in structure, it is desirable to use condition it is harsher, situation slight variation,
Seal failure can be formed, causes to leak, pollutes environment.Axle envelope problem, which seems, to become increasingly conspicuous, and it is excellent to be badly in need of a kind of sealing effect,
The mechanical seal that consistency of performance is stablized.
Utility model content
In view of this, the utility model provides a kind of super corrosion resistant large arch dam mechanically-sealing apparatus, using flushing water to sealing
End face carries out high pressure washing, avoids the solid impurity of highly corrosive from depositing and causes damage in seal face to dynamic and static ring；In addition lead to
Cross transmission pressure ring axle sleeve is fixed on pump shaft, it is ensured that the concentricity of rotating ring and pump shaft.
To solve above technical problem, the technical solution of the utility model is to use a kind of super corrosion resistant large arch dam mechanical seal
Device, including axle sleeve and the one group of rotating ring and stationary ring sealed that cooperate；The axle sleeve front end is provided with bulge loop, described
The mounting base for installing rotating ring is provided with bulge loop, the rotating ring is embedded in mounting base and is fastened using collar；The stationary ring
It is fixed in the installation set being connected with pump case, and its rear end is provided with the spring for pretension；The axle sleeve, bulge loop, installation
Set surrounds flushing chamber；The rotating ring, stationary ring and preloading spring are arranged at flushing intracavitary；The flushing chamber opening is arranged on dynamic
The surface of ring and stationary ring seal face；Flushing flow passage is provided with the installation set, the flushing flow passage outlet is arranged on flushing
Chamber opening, and it is vertical with seal face；The axle sleeve rear end is provided with transmission pressure ring, and the transmission pressure ring includes the son of lower section
Pressure ring and female pressure ring of top；The step of mutual cooperation is provided with the sub- pressure ring and female pressure ring, and step is phase interworking
The conical surface of conjunction；The sub- pressure ring and female pressure ring are fastened by bolt.
As an improvement the spring base for installing preloading spring is provided with the installation set；The preloading spring with
Throw-out collar is provided between stationary ring.The transmission of pretightning force is carried out using throw-out collar so that pretightning force is more uniformly applied on stationary ring,
It ensure that the uniformity of seal face.
As a kind of further improvement, the throw-out collar section is " 7 " shape, is placed on stationary ring end face.
The utility model is beneficial in that：Mechanically-sealing apparatus with said structure, prevents from being situated between using flushing water
Solid impurity siltation in matter causes to corrode in seal face to dynamic and static ring；And driving key transmission is substituted using transmission pressure ring, make
Obtain axle sleeve uniform force, it is ensured that the concentricity of rotating ring and pump shaft.
