Description

一种无渗漏水泵密封件  Non-leakage pump seal
技术领域 Technical field
本发明涉及一种水泵密封件， 具体讲为一种汽车用水泵密封件。  The invention relates to a water pump seal, in particular to a water pump seal for an automobile.
背景技术 Background technique
现有汽车水泵密封件普遍采用单级密封技术， 即通过一个动态的端面与另 一个静态的端面接触， 结合在一个位置上， 构造生成单个运动轨道位置， 阻止 介质从一个区域进入另一个区域， 此种单个位置应用隔离方式， 称为单级密封 技术。  Existing automotive water pump seals generally employ a single-stage sealing technique in which a dynamic end face is brought into contact with another static end face, combined in one position, to create a single motion track position that prevents media from entering one area from another. This single position application isolation method is called single-stage sealing technology.
但采用单级密封技术的动环端面沿静环端面运转摩擦， 受转速工况频繁强 烈变化的影响， 以及动静环在弹簧张力作用下的自动调节吸附力， 密封端面产 生波动， 平衡力差不匀， 稳定性降低。 在实际情况中， 密封介质解决不了纯净 问题， 介质中颗粒状物质随介质运动、 挤压、 窜入动、 静环端面， 动环旋转运 动作用带动颗粒状物质摩擦。 因静环体为石墨材料质地较软， 不耐硬质尖锐杂 屑的摩擦， 所以颗粒状物质进入后， 容易破坏损伤静环端面， 造成密封失效， 缩短了密封件使用周期。  However, the end face of the moving ring with single-stage sealing technology runs along the end face of the static ring, which is affected by the frequent and strong changes of the rotating working condition, and the automatic adjusting adsorption force of the moving and static ring under the action of the spring tension. The sealing end face generates fluctuations, and the balance force is not Uniform, reduced stability. In the actual situation, the sealing medium can not solve the problem of purity. The granular material in the medium moves with the medium, squeezes, breaks into the end of the static ring, and the moving motion of the moving ring drives the friction of the granular material. Because the static ring body is soft in graphite material, it is not resistant to the friction of hard and sharp debris. Therefore, after the particulate matter enters, it is easy to damage the end face of the static ring, causing seal failure and shortening the life cycle of the seal.
而且， 现有汽车水泵密封件普遍采用胶水来黏结密封件结合部， 由于受环 境条件决定， 所选用大多数胶粘剂凝结后即产生硬化， 粘贴部位胶层长期与水 接触， 势必加速硬化胶层自然老化分离， 因而产生接口不牢的可能， 缩短了密 封件使用寿命， 密封效果不可靠。 且目前粘接技术克服不了胶水在接口处不均 匀分布， 一些余胶外溢暴露， 影响了产品外观， 因此需要设计一种新型结构的 密封件来解决上述问题。  Moreover, the existing automotive water pump seals generally use glue to bond the joints of the seals. Due to environmental conditions, most of the selected adhesives are hardened after coagulation, and the adhesive layer on the adhesive parts is in contact with water for a long time, which is bound to accelerate the hardening of the rubber layers. The aging is separated, so the interface is not strong, the service life of the seal is shortened, and the sealing effect is not reliable. At present, the bonding technology can not overcome the uneven distribution of the glue at the interface, and some of the residual glue is exposed, which affects the appearance of the product. Therefore, it is necessary to design a new type of sealing member to solve the above problem.

本发明在动环体或静环体上设置环状凸出圈带， 与设置环状凹槽原理相同， 也是为了防止颗粒杂质停留于动、 静环的密封面， 损坏密封件或降低密封件的 性能， 多圈凸出圈带也起到了多级密封的作用。 The invention provides an annular protruding ring belt on the moving ring body or the static ring body, which is the same as the principle of providing the annular groove, and is also for preventing the particulate impurities from staying on the sealing surface of the moving and static rings, damaging the sealing member or reducing the sealing member. of Performance, multi-turn protruding band also plays a multi-stage seal.
动环体环状圈带端面光洁水平， 静环体采用石墨材料， 静环体密封端面平 滑水平， 因受旋转机械原理， 动环体上凸起的环状圈带端面与石墨静环体端面 发生摩擦研磨， 静环体端面发生变化， 动环体环状圈带端面在静环体端面间相 对应处研磨出环状凹痕槽， 两者端面形成对应啮合， 这样避免杂质进入动、 静 环体端面上。 即使杂质从研磨出的环状凹痕槽跑出， 杂质也停留在动、 静环体 因圈带而形成的间隙处， 不会破坏动、 静环接触面， 类同于凹槽结构中对杂质 的处理状态， 不会影响密封效果。 又由于动环体上的圈带数目为 2— 5道， 第二 道圈带还可以阻止杂质的侵入。 所以静环体上设置环状凸起圈带的原理与静环 体上设置凹槽的原理相同。  The ring body of the moving ring has a smooth surface level, the static ring body is made of graphite material, and the end surface of the static ring body is smooth and horizontal. Due to the principle of rotating machinery, the end face of the annular ring band on the moving ring body and the end face of the graphite static ring body Friction grinding occurs, the end surface of the stationary ring body changes, and the end face of the ring body of the moving ring body grinds the annular indent groove at the corresponding position between the end faces of the stationary ring body, and the end faces of the two end portions are correspondingly meshed, so as to prevent impurities from entering the moving and static state. On the end face of the ring. Even if the impurities run out of the ground annular indentation groove, the impurities remain in the gap formed by the moving and stationary ring bodies due to the loops, and the moving and static ring contact faces are not damaged, similar to the groove structure. The treatment state of the impurities does not affect the sealing effect. Moreover, since the number of loops on the moving ring is 2-4, the second loop can also prevent the intrusion of impurities. Therefore, the principle of providing an annular raised band on the stationary ring body is the same as the principle of providing a groove on the stationary ring body.
在静环体的密封端面设计 2— 5道环状凹槽， 它与动环体的端面作相对运动 密封， 环状凹槽允许颗粒状物质进入， 颗粒状物质进入密封端面因受动环体旋 转带动而做不规则运动， 弹簧张力作不平衡调节， 颗粒状物质窜入第一道静环 体上的环状凹槽内， 颗粒状物质失去推动力， 无法从水平线穿越第二道密封防 线可能。 受介质不良影响， 新鲜颗粒状物质再次进入， 第一道凹槽体还是具备 优先权， 同样第二道凹槽体时刻设防等待颗粒状物质进入， 第三道是实施安全 密封的后盾。 通过动环体的运动摩擦对已经损伤的端面作规则研磨， 实现自动 修复平整， 所以不产生渗漏， 达到长久完好密封的效果。  In the sealing end face of the stationary ring body, 2-4 annular grooves are designed, which are opposite to the end faces of the moving ring body, and the annular groove allows the granular material to enter, and the granular material enters the sealing end face due to the moving ring body. Rotating and rotating, the spring tension is unbalanced, and the granular material breaks into the annular groove on the first static ring body. The granular material loses the driving force and cannot pass through the second sealing line from the horizontal line. may. Under the influence of the medium, the fresh granular material re-enters, and the first groove body still has priority. Similarly, the second groove body is forbidden to wait for the particulate matter to enter, and the third channel is the back seal for implementing the safety seal. Through the frictional friction of the moving ring body, the damaged end face is regularly ground to achieve automatic repair and flatness, so that no leakage occurs, and the effect of long-term perfect sealing is achieved.
既利于定位橡胶密封套， 又利于与静环座套侧壁相位紧密结合。 此同步嵌 入相位法的应用， 对密封件主体结构连接效果而言， 即使去除弹簧张力作用， 它们仍然牢固连接一体。 因为固定座圈、 静环座套都属同类硬性金属材料， 金 属物体相位紧密结合后， 无脱位松动可能。 其间的橡胶密封套既保证了与固定 座圈紧密接触， 又保证了与静环座套紧密接触， 从而实现了分体式连接、.无缝 一体密封结构。  It not only helps to position the rubber gland, but also helps to closely integrate with the side wall of the stationary ring seat cover. This synchronous embedded phase method is used to firmly connect the seal body structure to each other even if the spring tension is removed. Because the fixed seat and the static ring seat cover are all of the same kind of hard metal materials, after the metal objects are closely combined, there is no possibility of loosening. The rubber gland between them ensures close contact with the fixed race and ensures close contact with the static ring seat cover, thus achieving a split connection and a seamless integrated seal structure.
本发明由于采用多级密封技术， 利用不等距环状结构的隔离带形式， 把动 环体或静环体设置成多个运动轨道位置， 实现一个位置构造成多个轨道接触位 置， 控制密封介质从这一区域进入另一区域， 工作状态下动环体端面与静环体 端面因水膜作用， 运动时隔离带区域形成环状水带， 轨道与轨道位置因隔离水 带分离作用， 在端面密封间， 吸附力产生后， 形成自滑作用， 消除了因接触面 积增大， 扭力增大的阻力影响。 本发明通过多层环状结构的设置可有效防止杂 质进入密封端面， 增强了密封效果和增长了密封件使用周期。 The invention adopts a multi-stage sealing technology, and adopts the form of the isolating belt of the unequal annular structure to set the moving ring body or the static ring body into a plurality of moving track positions, thereby realizing one position to construct a plurality of track contact positions, and controlling the sealing. The medium enters another area from this area. Under the working condition, the end face of the moving ring body and the static ring body Due to the action of water film, the end face forms an annular water belt during movement. The orbital and orbital position are separated by the isolation water belt. After the adsorption force is generated, the self-sliding effect is formed, which eliminates the contact area. , the resistance of the increased torque resistance. The invention can effectively prevent impurities from entering the sealing end surface by the arrangement of the multilayer annular structure, enhance the sealing effect and increase the life cycle of the sealing member.
本发明还在橡胶套上设计多圈环槽， 利用嵌槽式原理及弹簧张力使橡胶套 与其他部件紧密结合， 完全摒弃了现有技术的胶水黏结方式， 通过对密封件主 体结合部位实施嵌入式结构设计， 在橡胶密封套上下端面周围设计环槽， 并同 样在动环密封圈周围设计环槽。 通过环槽过盈尺寸嵌入凹槽体内， 结合部位接 触面积发生变异， 两者之间接触紧密挤压， 因此增强了长久密封效果， 又可以 完全固定橡胶密封套与静环座套紧密接触。  The invention also designs a multi-ring ring groove on the rubber sleeve, and uses the groove-type principle and the spring tension to tightly bond the rubber sleeve with other components, completely omitting the glue bonding method of the prior art, and embedding the joint portion of the sealing body by embedding The design of the structure, the ring groove is designed around the upper and lower end faces of the rubber sealing sleeve, and the ring groove is also designed around the moving ring sealing ring. Through the groove groove interference size embedded in the groove body, the contact area of the joint portion is mutated, and the contact between the two is tightly pressed, thereby enhancing the long-term sealing effect, and completely fixing the rubber sealing sleeve and the static ring seat cover in close contact.
本发明完全摒弃了现有技术的胶水黏结方式， 结构上增加了橡胶套和动环 密封圈的环槽来增加与其他部件的接触面积， 使之紧密贴在一起， 再加上对橡 胶密封套固定座圈和动环座轴套的改进， 密封效果比以前好 50%。 完善了长寿 命设计理念， 起到了良好的防泄漏作用， 使整个水泵密封件的质量提升了一个 台阶。 .  The invention completely abandons the glue bonding method of the prior art, structurally increases the ring groove of the rubber sleeve and the moving ring sealing ring to increase the contact area with other components, and makes them close together, together with the rubber sealing sleeve The improvement of the fixed race and the moving ring seat bushing is 50% better than before. The longevity design concept has been improved, and a good anti-leakage effect has been achieved, which has improved the quality of the entire pump seal. .

如图 1所示， 本发明的密封件包括动环体 1、 静环体 2、 动环座套 6、 静环 座套 8、 动环密封圈 7、 弹簧 3、 弹簧座圈 4及橡胶密封套 5。 动环体 1一般采 用陶瓷材料或不锈钢金属材料制成， 静环体 2—般采用石墨材料制成， 材质较 软。 动环体 1套装于动环座套 6上， 动环体 1与动环座套 6之间设置动环密封 圈 7。动环体 1的下表面与静环体 2的上表面相配合紧密配合，在动环体 1与静 环体 2的接触面上设有三圈沉积凹槽， 凹槽开在静环体的上表面上， 静环体环 状凹槽 11深度为 10mm， 宽度为 10mm。 三圈沉积凹槽采用不等距排列。  As shown in FIG. 1, the sealing member of the present invention comprises a moving ring body 1, a stationary ring body 2, a moving ring seat cover 6, a stationary ring seat cover 8, a moving ring sealing ring 7, a spring 3, a spring seat 4 and a rubber seal. Set of 5. The moving ring body 1 is generally made of a ceramic material or a stainless steel metal material, and the static ring body 2 is generally made of a graphite material and has a soft material. The moving ring body 1 is set on the movable ring seat cover 6, and a moving ring sealing ring 7 is arranged between the moving ring body 1 and the moving ring seat cover 6. The lower surface of the moving ring body 1 is closely matched with the upper surface of the stationary ring body 2, and three floating grooves are formed on the contact surface of the moving ring body 1 and the stationary ring body 2, and the groove is opened on the stationary ring body. On the surface, the ring-shaped annular groove 11 has a depth of 10 mm and a width of 10 mm. The three-turn deposition grooves are arranged in unequal distances.
如图 5所示， 本发明的密封件 16安装在泵体的轴连轴 14上， 静环座套 9 固定在泵体 13密封腔内， 安装时密封件 16受压， 使弹簧 3产生一定的压力， 旋转叶轮 15位于动环座套 6上端， 动环座 6固定在轴连轴 14上并随之运动， 带动动环体 1旋转。 静环体 2.不旋转， 动、 静环体 2通过弹簧 3的压缩弹力而 紧密配合， 并能根据工况自动调节。 橡胶密封套 5上端面与静环体 2下部接触 面相互粘贴， 下端抵在静环座套 8内并与其粘贴， 弹簧 3套装在橡胶密封套 5 外部，弹簧 3的两端设有弹簧座圈 4。静环体 2与橡胶密封套 5接触面一侧的外 部边缘设有延伸 19， 并与弹簧座圈 4连接， 这样有效增加了静环体 2与橡胶密 封套 5的粘贴接触面积， 提高了粘贴强度， 产品也更美观。 当颗粒杂质进入动、 静环体的接触面时， 颗粒因受动环体 1旋转带动而作不规则运动， 弹簧 3张力 作不平衡调节， 使颗粒容易掉入第一道凹槽， 不会动、 静环体的接触面。 同样 第二道凹槽体的设置也可以防止颗粒杂质停留在动、 静环体的接触面上， 第三 凹槽起到更进一步的密封作用， 同时三圈不等距的凹槽更有利于密封。 并通过 动环体 1运动摩擦对已经损伤的端面作规则研磨， 实现自动修复平整， 不易发 生泄漏现象， 达到长久完好密封的效果。  As shown in FIG. 5, the sealing member 16 of the present invention is mounted on the shaft connecting shaft 14 of the pump body, and the stationary ring seat sleeve 9 is fixed in the sealing chamber of the pump body 13.

The outer edge of the side of the contact surface of the static ring body 2 and the rubber sealing sleeve 5 is provided with an extension 19 and is connected with the spring seat ring 4, which effectively increases the adhesive contact area of the static ring body 2 and the rubber sealing sleeve 5, and improves the pasting. Strength, the product is also more beautiful. When the particulate impurities enter the contact surface of the moving and stationary ring body, the particles move irregularly due to the rotation of the moving ring body 1, and the tension of the spring 3 is unbalanced, so that the particles easily fall into the first groove, and will not The contact surface of the moving and stationary ring body. Similarly, the arrangement of the second groove body can prevent the particulate impurities from staying on the contact surface of the moving and static ring bodies, and the third groove serves as a further sealing effect, and the three-circle unequal grooves are more advantageous. seal.

Set of 5. The moving ring body 1 is generally made of a ceramic material or a stainless steel metal material, and the static ring body 2 is generally made of a graphite material and has a soft material. The moving ring body 1 is set on the movable ring seat cover 6, and a moving ring sealing ring 7 is arranged between the moving ring body 1 and the moving ring seat cover 6. The lower surface of the moving ring body 1 is closely matched with the upper surface of the stationary ring body 2, and three ring-shaped protruding ring bands are arranged on the contact surface of the movable ring body 1 and the stationary ring body 2, and the ring band is disposed on the movable ring body.

动环体 1的凸起的环状圈带端面与静环体 2的端面发生摩擦研磨，静环体 2 端面发生变化， 动环体环状圈带 10端面在静环体 2端面间相对应处研磨出环状 凹痕槽， 两者端面成对应啮合， 这样避免杂质进入动、 静环体端面上。 即使杂 质从研磨出的环状凹痕槽进入到密封件， 杂质也停留在动、 静环体因圈带而形 成的间隙处， 不会破坏动、 静环接触面， 类同于凹槽结构中对杂质的处理状态， 不会影响密封效果。 由于动环体环状圈带 10为三道， 第二道动环体环状圈带还 可以阻止杂质的侵入。 采用多级不等距的排列， 更好地起到了密封作用。  The end surface of the raised annular ring of the moving ring body 1 is frictionally ground with the end surface of the stationary ring body 2, and the end surface of the stationary ring body 2 changes, and the end surface of the ring body ring 10 of the moving ring body corresponds between the end faces of the stationary ring body 2 The annular indent groove is ground, and the end faces of the two are correspondingly engaged, so as to prevent impurities from entering the end faces of the moving and stationary rings. Even if the impurities enter the sealing member from the ground annular groove groove, the impurities stay at the gap formed by the moving and stationary ring body due to the loop band, and will not damage the moving and static ring contact surfaces, similar to the groove structure. The treatment state of the impurities does not affect the sealing effect. Since the moving ring annular band 10 is three, the second moving ring annular band can also prevent the intrusion of impurities. Multi-level unequal spacing is used to better seal.

The principle is basically the same. Moreover, the materials of the moving and stationary rings can be interchanged, the moving ring body is made of graphite material, and the static ring body is made of ceramic or stainless steel.
