Paste the sealing position formed；Another grade is then the rubber ring covered on iron hoop outer ring.It is to float envelope iron by the inner diameter abutment of rubber ring
The periphery position of ring bores lubricating oil from this position is seamless；The outer circle outer diameter of cushion rubber be installed into take a seat chamber after with regard to because
It is axial to pressure and flexible deformation is close to the internal diameter wall surface of a chamber, leak lubricating oil can not also from this position and spill.Rubber ring
This primary seal, be exactly utilized rubber elastic force be clipped in have iron hoop face, have a cavity wall, the crack between both outside
In, two sides is close to, and realizes oil sealing function.After being mounted, cushion rubber is squeezed floating sealing ring by both iron hoop, seat chamber, deformation,
Tightly two sides is bonded the elastic recoil power of generation, and two sides oil sealing becomes the important level-one of sealing function.In practice, it floats
Stem seal design is not better more killing compression, to be moderately bonded.Because the screen resilience of cushion rubber, which is transmitted to iron hoop end face, makes 2
The work bright band face of iron hoop fits closely, and due to being active state oil sealing, also to have oil film infiltration on 2 iron hoop fitting end face bright bands
Enter.It is only and was not only able to rotate only so, but also energy oil sealing, this requires the appropriateness elasticity of rubber ring lucky to power.Iron hoop is bright in this way
Band binding face stress is appropriate, and existing oil film is formed, and abrasive forces are small, and can allow iron hoop long service life.Otherwise, press too tight, oil
Film does not become, and two iron hoop binding faces are just dry grinded, and will soon damage.Certain external pressure is too big, and the intracavitary external pressure of seat is uneven
Weighing apparatus, will cause reverse irrigation, this is that special operation condition environment causes, and need targeted design, gives pressure parameter, then shoulds be regarded as a different matter.And it floats
Why dynamic oil sealing is referred to as " floating ", just refers to that rubber ring is squeezed by two seat chambers, two iron hoops are squeezed by two rubber rings
It fits together.At this moment the one-to-one fitting of iron hoop is integral, what fixing piece to fix them without, and " suspension " in centre.And
And wherein a bar chamber, cushion rubber, iron hoop combination can be with random device rotary moveable.By the elasticity of both ends rubber ring, driving wheel
This side seat chamber, cushion rubber, iron hoop combination when rotated, can because of rubber ring Flexible change, iron hoop and with slightly having as elasticity
It beats, what a pair of of iron hoop seemingly " suspended " can rotary motion but also oil sealing.
The novel float grease seal, dexterously applies spraying technology, and ultrawear-resistant material is sprayed to iron sheet ring end face.It solves
Anti abrasive quality problem, to enable iron sheet ring and plastic hoop dexterously combination replacement conventional metals floating sealing ring.It is this only
It creates unique novel iron plastic combination float grease seal ring and has four big advantages: 1. energy conservation and environmental protections compared with conventional metals floating sealing ring；2. skill
Art is advanced, high production efficiency；3. digitlization, high degree of automation；4. super quality and competitive price, cost performance is high.So having very strong city
