瑞典的密封试验经常用于评估组装好的徐州NSK轴承汽缸密封件及其接头的组装和可靠性，例如汽缸端口的密封和连接、汽缸活塞上的动密封和静态密封(在杆室和杆室之间)以及密封条件。由于试验压力高，特别是在无杆室压力试验和活塞杆试验中，活塞承受不了活塞杆上的巨大压力。因此，对于这种压力测试，通常在气缸经过仔细组装之后对整个装配机进行调试。
Sealing tests in Sweden are often used to evaluate the assembly and reliability of assembled Xuzhou NSK bearing cylinder seals and their joints, such as the sealing and connection of cylinder ends, dynamic and static seals on cylinder pistons (between rod chambers and rod chambers), and sealing conditions. Because of the high test pressure, especially in rodless chamber pressure test and piston rod test, the piston can not withstand the huge pressure on the piston rod. Therefore, for this kind of pressure test, the whole assembly machine is usually debugged after the cylinder is carefully assembled.
汽缸所属的齿条承受很大的压力。如果汽缸总成没有问题，整个汽缸总成压力测试将顺利进行，这不仅节省了汽缸徐州NSK轴承总成的个人压力测试，而且节省了相应的工作时间，缩短了生产周期，有利于生产；如果汽缸总成有问题，柏林将予以解决。被收养。将组装。Embly和试运行将被公开，它将从新组件中删除，但是它将花费时间和金*钱。没有红利，工作就会影响生产进度。这往往是管理者失败、认真学习和努力工作的结果。
The rack to which the cylinder belongs bears a great deal of pressure. If there is no problem with the cylinder assembly, the whole cylinder assembly pressure test will proceed smoothly, which not only saves the personal pressure test of the cylinder Xuzhou NSK bearing assembly, but also saves the corresponding working time, shortens the production cycle and is conducive to production; if there is a problem with the cylinder assembly, Berlin will solve it. Adopted. Will be assembled. Embly and trial run will be made public, and it will be removed from the new component, but it will take time and money. Without dividends, work will affect production progress. This is often the result of managers'failure, serious study and hard work.
因此，在瑞典组装徐州NSK轴承之前，必*须仔细检查相关零件的尺寸精度以满足附图。密封失效往往是由于对密封沟槽的要求过高或密封表面粗糙度的尺寸精度不理想造成的。其次，应仔细检查密封件的几何形状，尤其是密封唇。因此，诸如不规则形状缺点、缺肉、小裂纹等不能仔细检查。密封件装入产品中。
Therefore, before assembling Xuzhou NSK bearings in Sweden, it is necessary to carefully check the dimensional accuracy of the relevant parts to meet the drawings. Sealing failure is often caused by high requirements for sealing grooves or unsatisfactory dimensional accuracy of sealing surface roughness. Secondly, the geometry of the seals, especially the sealing lip, should be carefully checked. Therefore, such as irregular shape defects, lack of meat, small cracks and so on can not be carefully examined. Seals are loaded into the product.
此外，瑞典徐州NSK轴承的密封材料、硬度等指标应与产品证书和仓库收据检验进行比较。例如，O形环具有四个压力等级i-1-i-14，其承载能力从低到高变化。特别是对于那些没有经验的人来说，很难把密封圈与同样的尺寸区分开来。如果低压密封环没有正确地安装在高压部件中，则组装过程不会有问题。因此，在试验或工作中，密封件容易分*解，导致密封失效或使用寿命显著缩短。徐州NSK轴承的影响和损失是可以想象的。
In addition, the sealing material and hardness of NSK bearings in Xuzhou, Sweden should be compared with the inspection of product certificates and warehouse receipts. For example, the O-ring has four pressure levels i-1-i-14, and its bearing capacity varies from low to high. Especially for those who are inexperienced, it is difficult to distinguish the sealing ring from the same size. If the low pressure sealing ring is not properly installed in the high pressure components, the assembly process will not be a problem. Therefore, in the test or work, the seals are easy to be decomposed, leading to seal failure or service life significantly shortened. The influence and loss of Xuzhou NSK bearings can be imagined.
