Description
Technical field
A kind of mechanically-sealing apparatus is the utility model is related to, specifically a kind of mechanical sealing device used for pump.
Background technology
Mechanical sealing device used for pump refers to be mainly used in prevent the device that fluid leaks, and it comprises at least a pair as sealing
The dynamic friction ring and static friction ring, rotating ring and stationary ring of piece are in Fluid pressure and compensation mechanism elastic force（Or magnetic force）Effect is lower and auxiliary
Help under the cooperation of sealing and keep fitting and relative can slide.In general mechanically-sealing apparatus includes dynamic friction ring, static friction ring
With spring, the end face and the end face of static friction ring of dynamic friction ring are brought into close contact.
The mechanically-sealing apparatus used on pump, because the lift of pump drainage is different, and the liquid matter of pump drainage is different（As sewage,
Corrosive liquid）, mechanically-sealing apparatus contacts with liquid, can be damaged by liquid corrosion for a long time, causes pump cisco unity malfunction, if
Ensure pump energy normal work, the protection to mechanical seal is crucial.Parts in existing mechanical sealing device used for pump are easy
Be corroded damage, and its replacing maintenance cost is higher.
Utility model content
The purpose of this utility model is to provide a kind of mechanical sealing device used for pump, is filled with solving existing mechanical seal for pump
The problem of perishable damage present in putting and high maintenance cost.
What the utility model was realized in：
A kind of mechanical sealing device used for pump, including dynamic friction ring, static friction ring and spring, in addition to be socketed in pump rotating shaft
Axle sleeve, be socketed on the axle sleeve be used for support dynamic friction ring sleeve block, it is fixedly sleeved the sleeve block with turn
The drive ring of one end corresponding to axle drive end and be socketed on the sleeve block be used for accommodate the spring and the static friction
The gland of ring, cooling chamber is formed between the gland, the static friction ring and the sleeve block；
The gland is nano composite material gland, and the gland is fixedly connected with the pump housing of pump, in the gland
Portion is axially arranged multi-stage stairs hole, and sealing ring is provided between the gland and the static friction ring；In the sleeve block
On be provided with throw-out collar for being interacted with the spring.
Lip-type packing is provided between the gland and the sleeve block.
Gland of the present utility model is nano composite material gland, instead of traditional stainless steel gland, nano combined material
The maximum temperature that material gland can bear is 200 °C, and its acidproof base number scope is 0 ~ 14, and its decay resistance is significantly larger than general
Traditional stainless steel gland, be entirely capable of meeting washing away and wearing for pump chamber inner high voltage slurry, its service life is stainless steel pressure
Three times of lid service life, and its intensity is equal to gray iron material commonly used at this stage.In addition, nano composite material gland
Mechanical performance and nonmetallic density with metal, can fully meet machinery sealing material manufacture require and use will
Ask, significantly reduce the weight of mechanically-sealing apparatus, it is installed and is assembled and more facilitate.In addition, nano composite material uses
Cast cold technique is made, and any destruction will not be produced to environment, it is entirely avoided stainless steel material adds in casting and machine
Caused high energy consumption and the shortcomings of heavily contaminated in work, greatly protects environment.
The utility model reduces seal junction position, reduced simultaneously compared to traditional mechanical sealing device used for pump
The usage quantity of parts, so both increases sealing reliability, reduces seal assembly factor of damage again, improves mechanical seal
The service life of device.
