Abstract
The utility model relates to a novel pump ring sealing washer, and the cross section of the pump ring sealing washer is composed of six sides. An outer cylindrical surface 2 and a lip opening are parallel to an axis line of a reciprocating motion rod 9, and a front end face 1 and a back end face 3 are vertical to the axis line of the reciprocating motion rod 9. A back cone face 4 and the reciprocating motion rod 9 form an oil wedge angle phi (1) which is smaller than a stable angle phi (2) formed a front cone face 6 and the reciprocating motion rod 9. The utility model has the advantages of simple structure, compact structure, good manufacturability, low cost, wide sealed medium pressure range, good and reliable sealing effect, long service life, big bearing side force, etc. The utility model can be used in a shock absorber of an automobile or a motorcycle, various hydraulic devices and specific compressors.
Description
The utility model relates to a kind of ring seal ring, especially is being used for the new pump ring seal ring at reciprocating movement rod place now.
Existing reciprocating movement rod place medium-tight adopts structures such as O type cushion rubber or oil seal, is to utilize the compressive strain of Sealing to remove to stop up leakage way, exists deficiency, not lubricated, dry friction easily produces heat, impels Sealing distortion, rotten, and working life is short.In the patent disclosure of number of patent application 94217419.4 " a kind of reciprocating pump self sealing plunger packing_seal ", still exist complex structure, the high deficiency of cost.
At above-mentioned deficiency, the purpose of this utility model provides a kind of simple in structure, easily makes, and cost is low, can effectively seal, and makes the oil new pump ring seal ring of timely blowback oil pocket of bar.
The purpose of this utility model is to realize like this, include sealing seat, pressing plate, reciprocating movement rod, oil pocket, the section of its pump ring seal ring is that six limits are formed, the axis parallel of external cylindrical surface and lip and reciprocating movement rod, front-end face is vertical with the shaft axis of reciprocating movement rod with ear end face, and rear cone and reciprocating movement rod constitute oil film wedge angle
1Constitute angle of stability less than inner cone and reciprocating movement rod
2When pulling out stroke, pump ring seal ring starting seal action has a small amount of oil to adhere to reciprocating movement rod and is taken out of the utility model at reciprocating movement rod, makes pump ring seal ring obtain good lubricating; When being pressed into stroke, sealing encloses pumping effect, makes the timely blowback oil pocket of oil on the bar, and the drag-out of the oil of pump oil ability when pulling out stroke prevents that oil from externally piling up, and causes seepage; During the reciprocating movement rod stop motion, pump ring seal ring then plays the static seal effect.Pump ring seal ring can use separately, also can be with the overlapping use of a plurality of pump ring seal ring, to strengthen pump oil ability.
Since adopt technique scheme, compared with prior art simple in structure, compact, good manufacturability, cost is low, is sealed the pressure medium wide ranges, good sealing effect and reliable, the life-span is long, can bear bigger characteristics such as flank force.Can be widely used in the vibration damper of automobile and motorcycle, various hydraulic equipment and the special compressor product.
Below in conjunction with accompanying drawing the utility model is further specified.
Accompanying drawing is the utility model sectional structure schematic representation.
Among the figure: 1-front-end face, 2-external cylindrical surface, 3-ear end face, 4-rear cone, 5-lip, 6-inner cone, 7-sealing seat, 8-pressing plate, 9-reciprocating movement rod, 10-oil pocket
As shown in drawings, sealing seat 7 and pressing plate 8 form attachment faces such as front-end face 1 that grooves are mounted with pump ring seal ring, ear end face 3, external cylindrical surface 2 and locate, and lip 5 is fitted with reciprocating movement rod 9, and rear cone 4 constitutes oil film wedge angle with reciprocating movement rod 9
1, inner cone 6 constitutes angle of stability with reciprocating movement rod 9
2, oil pocket 10 fills the oil of pressure.
