Description
Technical field
The utility model relates to Sealing field, particularly relates to the plunger type superhigh pressure sealing of ultrahigh pressure water pump.
Background technique
Existing conventional high-pressure water pump plunger shaft plug superhigh pressure sealing mostly is V-type Combination Design, sealed material mostly is folder cloth material or duroplasts, bearing capacity is generally lower than 250MPa, because folder cloth material is in the impact of superhigh pressure liquid and meeting deliquescing, distortion in soaking, thus lose anti-high pressure ability very soon, working life is shorter; Sealed material be the V-seal ring of duroplasts due to the main pressured tightening seal of design principle, temperature raises fast, and quick abrasion, sealing effect is undesirable, and working life is not long yet.The operation of the said goods in high-pressure water pumping unit is generally no more than 300 hours working life.
Model utility content
For solving above technical problem, the utility model provides a kind of plunger type superhigh pressure sealing of novel super-high water pump.
The technological scheme that the utility model adopts for its technical problem of solution is,
A plunger type superhigh pressure sealing for novel super-high water pump, comprises the first trapezoidal combination back-up ring, the second trapezoidal combination back-up ring, seal ring, elastomer; First trapezoidal combination back-up ring, the second trapezoidal combination back-up ring cross section be there is phase co-altitude, equal length upper base and two of going to the bottom trapezoidal; When mounted, is fitted in the inclined-plane of the first trapezoidal combination back-up ring, the second trapezoidal combination back-up ring, make the first trapezoidal combination back-up ring, the second trapezoidal combination back-up ring is combined to form a cuboid; Be provided with seal ring between second trapezoidal combination back-up ring and elastomer, seal ring inner diameter seal face adopts ramp type design, and seal ring root internal diameter is greater than plunger diameter; Elastomer entirety is quad flat shape, its root outer diameter chamfering.
Further, seal ring material is ultra high molecular weight plastic or fills reinforced TFE.
Further, elastomer is rubber elastomer.
By adopting above technological scheme; when seal ring and elastomer bear ultrahigh pressure; the cylinder body be connected with Sealing can expand; the trapezoidal Combination Design of the first trapezoidal combination back-up ring, the second trapezoidal combination back-up ring can make the external diameter of the second trapezoidal combination back-up ring synchronously become large along with the expansion of cylinder body; thus the external diameter well protecting seal ring can not be extruded; and seal ring inner diameter seal face adopts ramp type design; its root internal diameter is greater than plunger diameter, and thus the second trapezoidal combination back-up ring can effectively stop the internal diameter of seal ring to be extruded.Elastomer adopts quad flat design, root outer diameter chamfering, effect stability during high-pressure work, and anti-plasticating capacity is strong, and greatly improve bearing capacity and working life, the highest pressure-bearing can reach 380MPa pressure.
Further, seal ring material is ultra high molecular weight plastic or fills reinforced TFE.
The utility model improves the sealing load grade of ultrahigh pressure water pump industry and substantially prolongs the Sealing replacement cycle of high-pressure water pumping unit, improves the utilization efficiency of equipment.
