Description

The gluing technique of " λ " sealing ring
Technical field
The present invention relates to the gluing technique of " λ " sealing ring more particularly to the production technologies of polyurethane sealing ring.
Background technique
The structural shape for " λ " the type sealing that the runner seals of movable propeller turbine use, it is sometimes desirable to increase perimeter, Gluing is carried out after cutting open again, at this point, sealing bonding after repeatedly there is a large amount of oil leak, cause serious environmental pollution and Weight huge economic loss, analysis and research to this oil leak situation propose and replace toluene with dichloroethanes, close with nitrile rubber Seal replaces nitrile rubber rubber cement, is bonded with the sealing that aviation gasoline makees detergent, and carry out with regard to specific runner seals example Using thus not only demonstrating the feasibility of new method, but also effect is fine, the advantages of this sealing is that structure is simple, is not torn open Blade can replace sealing ring, apply on power station water cleaning, medium-sized unit, substantially satisfactory.
Pass through the summary of experience of operation observation and overhaul plan over more than 20 years: thinking that this sealing device belongs to compression The wide type rubber dynamic sealing of formula, sealing principle are to force the disconnected of " λ " sealing ring by the effect for the spring and oil pressure for holding out against ring Face pressure contracting, to obtain sufficiently large contact pressure on sealing surface, thinks by analysis, glutinous using above-mentioned " λ " sealing ring It connects method and adhesive material is unreasonable, this is because original coheres principle, be approximately equivalent to packing seal;And due to rubber Glue dry friction factor is big, just will appear following some problems after unit operation: due to worrying sealing effect, often in assembly Apply big pressing force, cause the dry friction between rubber and pivot and web, is easiest at sealing ring gluing point Layer and out-of-flatness and tear, so that oil leak occur；When hold out against spring force that ring is subject to it is uneven when, be easy to appear inclination, hair Card is easy slight crack occur after being squeezed since the filler at sealing ring gluing position is uneven, cause concentrated wear so that tearing and Oil leak, the 3 F units expansion in 2005~2006 years install also serious oil leak after sealing, afterwards by improving material in repairing With sealing technique for sticking, good effect is achieved.
Summary of the invention
Goal of the invention: the technical issues of compression sealing ring to be solved by this invention is tearable, oil leak, the present invention provide The gluing technique of " λ " sealing ring.
Process program: the present invention provides the gluing technique of " λ " sealing ring, includes the following steps:
Step 1: preparing raw material and equipment: sealing ring, space flight gasoline cleaning agent, nitrile rubber raw stock, nitrile rubber are close Seal, pressure regulator, 0~200 DEG C of semiconductor point thermometer, heating mould, 3kW infrared heating piece, file；
Step 2: cohering step: first cutting sealing ring along 75 ° of direction open, and with file by sealing ring cutting opening It polishes flat, so that interface flawless, sealing ring is equipped with 2 connectors after cutting, and is cut sealing ring with aviation gasoline cleaning agent Two joints opened clean up, and after drying, coat configured nitrile rubber nitrile rubber sealing ring in two joints, It dries, coats nitrile rubber sealing ring to two joints again, and paste and be cleaned immediately in one end of sealing ring interface " λ " type nitrile rubber raw stock, and coat nitrile rubber sealing ring on its surface, paste " λ " type nitrile rubber raw stock Afterwards, first sealing ring interface one end is put into heating mould left side, and heating mould is fixed by side bolt, then will During the other end is put on the right side of heating mould and dock smooth, equally, upper and lower sides are fixed, and load onto remaining in heating mould Mold is wrapped up with 3kW heating sheet and being heated by cover board and fixation, and thermometer is inserted into thermometer hole and carries out thermometric, by temperature plus Heat keeps the temperature 40 minutes, cuts off the power to 150 DEG C；
Step 3: taking out sealing ring, after cooling, mold is opened, takes out sealing ring, after being cooled to, is checked, Connector answers the defects of dislocation-free, interlayer, stomata, slight crack, carries out finishing processing to seal nipple, with fine sandpaper gently sand hair loss Side and local high spot.
Further, the nitrile rubber sealing ring presses dichloroethanes: water=15: 100 proportional arrangement is being impregnated 10min。
Further, described " λ " the type nitrile rubber raw stock is 1mm bigger than sealing ring connector, in this way can be preferably by sealing Circle wraps up, and prevents due to bottom pour ladle bring bad phenomenon.
Operation of the present invention step is simple, structure novel, sealed reliable, can promote the use of in unit expansion property maintenance.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the present embodiment " λ " type sealing ring.
Fig. 2 is the structural block diagram of the gluing technique of the present embodiment " λ " sealing ring.
Specific embodiment
The present invention is further elaborated below in conjunction with attached drawing and by specific embodiment, it should be pointed out that: for this technique For the common process personnel in field, without departing from the principle of the present invention, to repairing for various equivalent forms of the invention Change and falls within the application range as defined in the appended claims.
As shown in Figure 1, process program: the present invention provides the gluing technique of " λ " sealing ring, includes the following steps:
Process program: the present invention provides the gluing technique of " λ " sealing ring, includes the following steps:
Step 1: preparing raw material and equipment: sealing ring, space flight gasoline cleaning agent, nitrile rubber raw stock, nitrile rubber are close Seal, pressure regulator, 0~200 DEG C of semiconductor point thermometer, heating mould, 3kW infrared heating piece, file.
Step 2: cohering step: first cutting sealing ring along 75 ° of direction open, and with file by sealing ring cutting opening It polishes flat, so that interface flawless, sealing ring is equipped with 2 connectors after cutting, and will then be cut with aviation gasoline cleaning agent Sealing ring joint clean up, after drying, coat configured nitrile rubber sealing ring in sealing ring joint, dry in the air It is dry, nitrile rubber sealing ring is coated to sealing ring joint again, and paste immediately in one end of sealing ring interface cleaned " λ " type nitrile rubber raw stock crossed, the nitrile rubber raw stock is 1mm bigger than sealing ring connector, in this way can preferably by Sealing ring wraps up, and prevents due to bottom pour ladle bring bad phenomenon, and coats nitrile rubber sealing ring, institute, institute on its surface Nitrile rubber sealing ring is stated by dichloroethanes: water=15: 100 proportional arrangement is impregnating 10min, described by " λ " type fourth After nitrile rubber raw stock posts, first sealing ring interface one end is put into heating mould left side, and heating mould is passed through into side spiral shell Bolt is fixed, then by the other end be put on the right side of heating mould in and dock smooth, equally, upper and lower sides are fixed, and are being heated Remaining cover board and fixation are loaded onto mold, with 3kW heating sheet by mold wrap up heat, by thermometer be inserted into thermometer hole in into Temperature is heated to 150 DEG C, keeps the temperature 40 minutes, cut off the power by row thermometric.
Step 3: taking out sealing ring, after cooling, mold is opened, sealing ring is taken out, is cooled down, is checked, Connector answers the defects of dislocation-free, interlayer, stomata, slight crack, carries out finishing processing to seal nipple, with fine sandpaper gently sand hair loss Side and local high spot, so that the more smooth beauty in surface.
