橡胶密封件厂家浅谈世界10大密封件厂商，你都了解么？

密封件广泛应用于从厨房用具到核电设备的各个领域。

Seals are used in a wide range of applications.

密封件定制主要分为静态密封件和动态密封件。静态密封是指密封件及其密封装置腔体的相对固定，而动态密封是指相对运动。例如，液压缸的密封部分对缸内的缸壁进行密封，如果它在缸壁上上下移动，就是动态密封。

A static axial seal acts similar to a gasket in that it is squeezed on both the top and bottom of the O-ring's cross section. This type of seal is typically employed in the face (flange) type applications. Dynamic seal is used in situations involving reciprocating, rotating or oscillating motion. Dynamic seal performance may be substantially affected by a number of operating environmental factors.

静态密封最简单的例子就是保鲜盒的密封条

动态密封和静态密封的差异

The difference between Dynamic Seal and Static Seal.

静密封可分为三类：垫圈密封、胶水密封和接触密封。

Static seal is divided into: pad seal, plastic seal, and touch seal.

动密封可分为两类：旋转动密封和线性动密封。密封方法分为相对停止接触表面之间的静态密封和相对运动接触表面之间的动态密封。

Dynamic seal can be divided into two categories: rotary variable seal and reciprocating dynamic seal.

静密封：根据工作压力，静密封可分为低压静密封和高压静密封。中低压静密封通常由软质材料和宽垫圈组成，而高压静密封则由硬质材料和窄接触宽度的金属垫圈组成。

Static seal: According to operating pressure, static seal can be divided into low pressure static seal and high pressure static seal.

动态密封：根据密封件是否与相对运动部件接触，可分为接触式密封和非接触式密封。

Dynamic seal: According to the relative movement of the seal with the zero-degree pieces has been touched or not, it can be divided into touch-type seal and non-touch seal.

一般来说，接触式密封具有良好的密封性能，但受到摩擦和磨损的限制。适用于低密封面。在接触式密封中，根据密封的接触位置，它们可分为周向（径向）密封和端面密封。端面密封又称机械密封。

Touch-type seal has good tightness, but it has a restraint in the conflict, wear constraints. It is suitable for the lower line of the occasion.

橡胶密封件的摩擦损失

非接触式动态密封包括迷宫密封和动态密封。前者泄漏量大，一般用于密封要求低的场合。动力密封有离心密封、浮环密封、螺旋密封等，它依靠密封两侧的压力差来抵消动力部件的压差，克服泄漏。它具有较高的密封性能，但耗能大，使系统难以获得较高的压力。

Non-touch seal is used of fluid in the gap between the savings effect of limiting leakage, the leakage is much larger.

非接触式密封，由于密封面不直接接触，启动功率小，使用寿命长。如果规划合理，泄漏不会太大。然而，这种密封是在流体力学的平衡条件下工作的。如果工作条件发生变化，将导致大量泄漏，这种密封不能在市场上购买。

However, this type of seal is used of fluid mechanics to balance the work. If the working conditions changed, it will lead to a huge amount of leakage.

密封材料的种类及用途  

Sealing material

密封材料应满足密封功能的要求。由于密封介质不同，设备工作条件不同，对密封材料的适应性要求也不同。通常需要密封材料。

The requirements for sealing materials:

1)材料致密性好，不易泄漏。

2)适当的机械强度和硬度；

3)压缩回弹性好，永久变形小；

4)低温下不软化、不分解、不硬化、不脆裂；

5)耐腐蚀性好，长期工作在酸、碱、油等介质中，其体积和硬度变化不大，且不粘附在金属表面；

6)摩擦系数小，耐磨性好；

7)具有与密封面结合的灵活性。

8)具有良好的耐老化性和耐久性；

9)加工制造工艺方便，价格相对便宜，材料容易获得。

1) The material is tight sealing and not easy to leak;

2) It has the appropriate mechanical strength and hardness;

3) Good compressibility and resilience;

4) It will not soften under high temperature, not decomposition, not hardened under low temperature, not brittle fracture;

5) Good corrosion resistance;

6) The friction coefficient is small, good wear resistance;

7) Good flexibility;

8) Good aging resistance;

9) Convenient for processing and manufacturing.

用于动态密封的最早材料是GCI（灰铸铁灰铸铁）。橡胶是最常用的静态密封材料，常见的有：氟橡胶、硅橡胶、乙丙二烯橡胶等。

The earliest dynamic seal material is used of GCI (gray cast iron). Rubber is the most commonly used sealing material, such as: fluorine rubber, silicone rubber and EPDM rubber.

通用橡胶密封产品广泛应用于国防、化工、煤炭、石油、冶金、交通、机械制造等行业，已成为各行业的基础零部件和配件。

Rubber sealing products are used more and more widely in the national defense, chemical, coal, petroleum, metallurgy, transportation and machinery manufacturing industries.

除橡胶外，石墨及各种密封剂也适用于密封材料。目前，一些密封件主要由塑料制成，主要是PEEK、PI、PTFE和PAI。这些高温聚合物将成为未来密封件制造技术的趋势，并且密封件的价格将越来越昂贵。

Except rubber, the sealing material also use graphite and other variety of sealants to produce seals. Today, some seals use plastic as raw material, such as PEEK, PI, PTFE and PAI. These high-temperature polymers will become the trend of seal manufacturing process in the future, the price of seals will become increasingly expensive.
