Abstract
The wide lip-shaped fluoroplastic water sealing circle is to belong to the Sealing that a kind of pumping plant is used, mainly solve in the water pump along the seepy question of rotatingshaft it by sheath body, shell, pad, liner, the fluoroplastic labial surface is formed.Have good seal performance, low cost of manufacture, initial water leakage ratio is low, and characteristics such as life-span length are a kind of water sealing members of novelty, and it is mainly used on the cooling water of internal combustion engine pump.
Description
The invention belongs to the Sealing that a kind of pumping plant is used.
U.S. MATHER company develops wide lip fluoroplastic oil sealing, be applied in the automobile engine crankshaft sealing, by the envelope medium is machine oil, life-span reached more than 10,000 hours according to reports, the main reference document has: No. the 3089th, U.S. SAE collection of thesis, exercise question: " Engineering and Manufacturing aspects of PTEE Seals ".
All adopt expensive " pottery-graphite " type mechanical seal at present on the cooling water of internal combustion engine pump, such Sealing manufacture cost is high presses the reload request strictness, and water pump initial stage sealing is poor, the object of the present invention is to provide a kind of low cost of manufacture, the initial stage good seal performance, the novel waterstop ring that life-span is long, fluoroplastic have corrosion-resistant, and are wear-resistant, resistant to elevated temperatures advantage, improve the structure of wide lip type oil sealing, adjust material prescription, just can be applied to be sealed the sealing that medium is the internal-combustion engine water pump of water.
This invention adopts teflon to make material, make horn-like wide lip, as shown in Figure 1, sealing lip 3 utilizes wide lip 6 to embrace rotating shaft 8 surfaces in order to avoid water flows out along axle 8, for improving dynamic airtightness, also can be carved with thread groove 7 at wide labial surface 6 inner side surfaces that contact with axle 8, sealing lip 3 is clamped by liner 4 and outer ring 2, and it is fixing, be water-impervious, the centre sandwiches rubber gasket 5, rubber sleeve 1 of cover on the sealed outer ring 2, avoid water 2 to ooze out from the outer ring when making the water seal circle pack water pump cover into, the width of wide lip 6 is no less than 3mm.
" pottery-graphite " type mechanical seal structure that this invention is used than original water pump is simple, low cost of manufacture, and it is low to press reload request, and the initial stage good seal performance reaches the advantage of long service life equally.
The used lip material of the present invention adopts teflon, and is filled with glass fibre (10-25%), graphite (0.5-10%), and molybdenum disulfide (0.5-1.5%), carbon (0.1-0.5%), to improve its performance, packing can be chosen by different purposes.
Accompanying drawing 1 is a structural drawing of the present invention.
Claims (4)
1, a kind of dynamic water sealing member is characterized in that; By the horn-like sealing lip 3 that teflon is made, be fixed between liner 4 and the outer ring 2, the wide lip 6 that can encase rotating shaft 8 is arranged on the sealing lip.
2, water sealing member according to claim 1 is characterized in that: sealing lip 3 profiles are horn-like wide lip structure, and the width of wide lip is not less than 3mm.
3, water sealing member according to claim 1 is characterized in that: there is rubber sleeve 1 outside of outer ring 2, and the internal surface of wide lip 6 also can be carved with thread groove 7.
4, according to claim 1,2,3 described water sealing members is characterized in that: the material of sealing lip is a teflon, and is filled with glass fibre (10-25%), graphite (0.5-10%), molybdenum disulfide (0.5-1.5%), and carbon (0.1-0.5%).
