瑞典的密封試驗(yàn)經(jīng)常用于評估組裝好的徐州NSK軸承汽缸密封件及其接頭的組裝和可靠性，例如汽缸端口的密封和連接、汽缸活塞上的動密封和靜態(tài)密封(在桿室和桿室之間)以及密封條件。由于試驗(yàn)壓力高，特別是在無桿室壓力試驗(yàn)和活塞桿試驗(yàn)中，活塞承受不了活塞桿上的巨大壓力。因此，對于這種壓力測試，通常在氣缸經(jīng)過仔細(xì)組裝之后對整個裝配機(jī)進(jìn)行調(diào)試。

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.

汽缸所屬的齒條承受很大的壓力。如果汽缸總成沒有問題，整個汽缸總成壓力測試將順利進(jìn)行，這不僅節(jié)省了汽缸徐州NSK軸承總成的個人壓力測試，而且節(jié)省了相應(yīng)的工作時間，縮短了生產(chǎn)周期，有利于生產(chǎn)；如果汽缸總成有問題，柏林將予以解決。被收養(yǎng)。將組裝。Embly和試運(yùn)行將被公開，它將從新組件中刪除，但是它將花費(fèi)時間和金*錢。沒有紅利，工作就會影響生產(chǎn)進(jìn)度。這往往是管理者失敗、認(rèn)真學(xué)習(xí)和努力工作的結(jié)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，在瑞典組裝徐州NSK軸承之前，必*須仔細(xì)檢查相關(guān)零件的尺寸精度以滿足附圖。密封失效往往是由于對密封溝槽的要求過高或密封表面粗糙度的尺寸精度不理想造成的。其次，應(yīng)仔細(xì)檢查密封件的幾何形狀，尤其是密封唇。因此，諸如不規(guī)則形狀缺點(diǎn)、缺肉、小裂紋等不能仔細(xì)檢查。密封件裝入產(chǎn)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軸承的密封材料、硬度等指標(biāo)應(yīng)與產(chǎn)品證書和倉庫收據(jù)檢驗(yàn)進(jìn)行比較。例如，O形環(huán)具有四個壓力等級i-1-i-14，其承載能力從低到高變化。特別是對于那些沒有經(jīng)驗(yàn)的人來說，很難把密封圈與同樣的尺寸區(qū)分開來。如果低壓密封環(huán)沒有正確地安裝在高壓部件中，則組裝過程不會有問題。因此，在試驗(yàn)或工作中，密封件容易分*解，導(dǎo)致密封失效或使用壽命顯著縮短。徐州NSK軸承的影響和損失是可以想象的。

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.
