   油封也称为轴封,是各类机械中不可或缺的部件。 它们主要用于密封机械设备中固定部件和移动部件之间的开口。 大多数应用中最常用的油封是橡胶壳油封或金属壳油封。   橡胶套管油封广泛用于存在金属套管油封因热膨胀而失效的风险的应用中。 橡胶外壳油封不会生锈,与金属外壳油封形成鲜明对比。 此外,它们可以更好地密封轻微损坏的外壳,因为橡胶可以在高温下提供更稳定的密封。   另一方面,当温度、系统压力或转速超过橡胶油封的能力时,金属外壳油封旨在取代传统的弹性体油封。 金属外壳油封旨在满足您特定的旋转密封设计要求。 此外,当安装到由相同材料制成的外壳孔中时,使用金属外壳油封。 这使得材料在操作过程中收缩和膨胀相等,从而防止发生泄漏。   这两种类型的油封在各种应用中都发挥着至关重要的作用。 橡胶套管油封常用于汽车发动机、液压缸、燃油系统等。 金属外壳油封可用于泵、电机和变速箱等旋转设备。   在为您的应用选择正确的密封件时,了解橡胶壳油封和金属壳油封之间的差异至关重要。 虽然这两种类型都具有防止泄漏和污染的相同通用目的,但它们的具体应用根据所用机械的性质而有所不同。

The Three Essential Functions of an Oil Seal

Image
   Oil seals are critical components widely used in mechanical equipment, with their primary roles falling into three categories: sealing, protecting, and lubricating.   Firstly, the most significant function of an oil seal is to provide sealing. In mechanical equipment, oil seals are utilized to prevent the leakage of lubricants, hydraulic oils, and other fluids and gases at the dynamic and static mating parts. By effectively sealing, oil seals ensure the stability of internal pressure within the equipment while preventing external contaminants from entering.   Secondly, oil seals serve a protective role. In many instances, mechanical equipment operates under harsh environmental conditions such as high temperatures, high pressures, or corrosive environments. Under these circumstances, oil seals protect the internal components of the equipment from damage.   Lastly, oil seals contribute to the lubrication of the equipment. By preventing the leakage of lubricating oil...

The Role of Sealers in Gasket Installation

Image
   A gasket is a mechanical seal that fills the space between two or more mating surfaces, generally to prevent leakage from or into the joined objects while under compression. Gaskets allow for “less-than-perfect” mating surfaces on machine parts where they can fill irregularities.   Sealers, on the other hand, are substances applied to a gasket to help it fulfill its function more effectively. They can provide additional sealing properties, protect the gasket material, and make the installation process easier.   However, whether a sealer needs to be used when installing a gasket depends on several factors. These include the type of gasket, the specific application, and the condition of the mating surfaces.   For some types of gaskets, such as pre-formed or composite gaskets, a sealer may not be necessary. These gaskets are designed to work without sealers and adding one might interfere with their function.   On the other hand, for flat paper or cork gaskets, using a...

What points should you pay attention to when purchasing seals?

Image
   Seals are essential components in machinery, serving to prevent leakage of fluids or gases. The selection of the right seal is crucial for the optimal performance and longevity of the machinery. Here are some key points to consider when selecting seals:   1. Operating Conditions: The temperature, speed, medium, and pressure under which the seal will operate are critical factors that determine the material and structure of the seal. These data can be obtained from the original equipment manufacturer’s specifications or evaluated based on the actual working environment.   2. Direction of Motion: The location of the seal and its direction of motion (whether it is a static or dynamic seal) are important considerations. If it’s a dynamic seal, you need to determine whether it involves reciprocating or rotary motion. The length of the stroke can also influence the structure of the seal.   3. Dimensions: Accurate dimensions are vital for ensuring a proper fit and effecti...

What are the key points for storing oil seals products?

Image
   Oil seal products, often used as spare parts, require long-term storage. The physical and chemical properties of the material from which the oil seal is made may change under the influence of deformation, oxygen, ozone, light, heat, humidity, oil, or solvents, potentially leading to seal failure. Therefore, understanding the key points in storing oil seal products is crucial.   The ideal storage temperature for oil seal products is between 10°C and 25°C. Exposure to heat sources and direct sunlight should be avoided. If an oil seal product is taken out of a low-temperature storage state, it should be placed in an environment of 20°C for a while before use.   Humidity also plays a significant role in the storage of oil seal products. The relative humidity of the warehouse should not exceed 60%. Conditions that are too humid can lead to condensation and compromise the integrity of the seals. However, conditions that are too dry should also be avoided.   In addition to...

Materials Suitable for Manufacturing High Quality Oil Seal?

Image
   The manufacturing of high-quality oil seals is a meticulous process that requires the selection of appropriate materials. The choice of material significantly influences the performance, durability, and overall lifespan of the oil seal. This article explores some of the most commonly used materials in the production of high-quality oil seals.   Nitrile Rubber (NBR)   丁腈橡胶又称NBR,是油封最常用的材料之一。 它是丙烯腈(ACN)和丁二烯的合成橡胶共聚物。 NBR 以其对石油、矿物油、植物油和许多酸的优异耐受性而闻名。 它还具有良好的耐磨性和拉伸强度。 这些特性使 NBR 成为油封暴露在恶劣条件下的应用的理想选择。 然而,值得注意的是,NBR 的性能可能会因暴露于臭氧、阳光或天气而降低。   氟橡胶 (FKM)   氟橡胶(通常以品牌名称 FKM 表示)是另一种流行的油封选择。 FKM 是一种合成橡胶,以其卓越的耐热性、耐化学品性和耐油性而闻名。 它可以承受高达 250°C 的温度,适合高温应用。 FKM 还具有出色的耐老化和耐臭氧性能。 然而,它比 NBR 更昂贵,并且可能不是低温应用的最佳选择。   聚丙烯酸酯 (ACM)   聚丙烯酸酯(ACM)是一类聚合物,以其透明性以及耐热性和耐紫外线辐射性而闻名。 ACM 油封在涉及高温和油的操作环境中特别有效。 它们对矿物油和合成油具有良好的耐受性,因此经常用于汽车应用。 然而,它们的低温性能较差,不适合涉及水或乙二醇基制动液的应用。   硅胶 (VMQ)   硅油密封 (VMQ) 以其优异的耐热性而闻名,能够承受高达 225°C 的温度。 它们还具有良好的冷柔韧性,并且耐臭氧和耐候。 然而,与 NBR 或 FKM 等其他材料相比,它们的拉伸强度和抗撕裂性较差。   制造高质量油封的材料选择取决于具体的应用要求。 ...

The Impact of Shaft Surface Roughness on Oil Seals Performance?

Image
   The performance and longevity of oil seals are significantly influenced by the surface roughness of the shaft with which they interact. If the shaft surface roughness is too high, exceeding Ra0.9μm, the peaks on the shaft surface will penetrate the oil film and come into contact with the seal lip, resulting in dry friction. This can lead to wear on the lip surface and an increase in oil film thickness beneath the lip, ultimately causing seal failure.   Conversely, if the shaft surface roughness is too low, falling below Ra0.12μm, the contact area between the seal lip and the shaft can be absorbed into the recesses on the shaft surface. This can lead to oil being squeezed out from beneath the lip, destroying the oil film and resulting in dry friction that wears down the seal lip.   Therefore, maintaining an optimal level of shaft surface roughness is crucial for ensuring effective sealing performance and prolonging the lifespan of oil seals. Generally, a surface roug...

Difference between Oil Seal with Spring and without Spring?

Image
   Oil seals also known as rotary shaft seals, are essential components used to prevent the leakage of lubricants and fluids in rotating machinery. They are commonly used in various industries such as automotive, manufacturing, and engineering. The design and structure of oil seals can vary significantly depending on their application. One key distinction lies in the presence or absence of a spring.   Functionality   带弹簧和不带弹簧的油封具有相同的基本目的,即防止液体和污染物泄漏。 然而,在油封中加入弹簧可带来额外的好处。 弹簧作为径向载荷元件,保证密封唇对轴的恒定压力,从而提高密封效率。 另一方面,不带弹簧的油封仅依靠密封件与轴之间的过盈配合来保持密封完整性。   密封效率   油封中弹簧的存在显着提高了其密封效率。 弹簧有助于补偿轴和密封件之间随着时间的推移可能发生的任何磨损或不对中。 它确保对轴施加连续的径向力,保持紧密密封并防止流体泄漏。 相比之下,不带弹簧的油封可能会因磨损或不对中而降低密封效率,从而导致潜在的泄漏。   安装与组装   与不带弹簧的油封相比,带弹簧的油封相对更容易安装和组装。 弹簧具有自动调节功能,可以在安装过程中更轻松地对准和定位。 弹簧还有助于在密封唇上保持恒定压力,确保牢固配合。 相反,不带弹簧的油封需要更精确的对准和仔细的安装才能实现有效的密封。   应用领域   带弹簧的油封通常用于轴未对准或振动程度较高的应用中。 弹簧补偿任何轴运动,确保密封唇上有恒定的径向力。 这使得它们适用于重型机械、汽车发动机和工业设备。 另一方面,不带弹簧的油封用于轴不对中和振动极小的应用,例如泵、压缩机和轻型机械。   寿命长、耐用   与不带弹簧的油封相比,带弹簧的油封通常具有更长的使用寿命和更高...

Why do rubber seals age?

Image
   Rubber seals are widely used in various industries due to their excellent sealing properties. However, over time, these rubber seals tend to deteriorate and age. In this article, we will explore the reasons behind the aging of rubber seals.   Firstly, one of the primary factors that contribute to the aging of rubber seals is exposure to sunlight and ultraviolet (UV) radiation. Rubber contains polymers that are susceptible to degradation when exposed to UV rays. The UV rays break down the chemical bonds in the rubber, leading to the loss of elasticity and the formation of cracks. Therefore, rubber seals used in outdoor applications or in environments with high exposure to sunlight tend to age more rapidly.   Secondly, temperature fluctuations can also accelerate the aging process of rubber seals. Extreme temperatures, both hot and cold, can cause the rubber to expand and contract. This repeated expansion and contraction weaken the rubber's molecular structure, makin...

What points should be paid attention to when using oil seal?
