Description
Technical Field
The utility model relates to a seal packing technical field specifically is a wave form tetrafluoro packing structure.
Background
The packing seal structure is a dynamic seal device which generates pressing force among packing, a rotating part and a fixed part through the pretightening or the self-tightening action of medium pressure. Also known as stuffing box sealing. The structure form is more, mainly comprises filler, stuffing box and filler mounting. The commonly used filler materials comprise asbestos fabrics, carbon fibers, rubber, flexible graphite, engineering plastics and the like, are prefabricated into rings or strips (some fillers with good lubricity need to be soaked in advance), and adopt a multi-ring or spiral multi-layer structure. The stuffing box is used for placing stuffing. The packing fixing part comprises a gland, a bolt, a spring and the like, so that the packing is pre-tightened, the medium is prevented from leaking outwards during working, and the spring can play a compensation role. After the edited packing is filled into the packing cavity, it is axially compressed by the gland screw, and when the shaft and the packing have relative motion, it produces radial force due to the plasticity of the packing and is tightly contacted with the shaft. At the same time, the lubricant impregnated in the filler is squeezed out, forming an oil film between the contact surfaces. Because the contact state is not particularly uniform, a 'boundary lubrication' state, namely a 'bearing effect', occurs at the contact part; the concave part which is not contacted forms a small oil groove with a thicker oil film, and the contact part and the non-contact part form an irregular labyrinth to play a role in preventing liquid flow from leaking, which is called as a labyrinth effect. This is the mechanism of the packing seal. Clearly, a good seal is to maintain the "bearing effect" and the "labyrinth effect". That is, good lubrication and proper compression are maintained. If the lubrication is poor or the pressure is too tight, the oil film is interrupted, dry friction between the filler and the shaft is caused, and finally the shaft is burnt and seriously worn
