皮带轮：想要更换大型洗衣机的水封，我们就应先知道水封的安装位置，如上所言，其是装在传动轴上依靠主轴边的。找到了其的位置，那么更换也就无非就是逐个部件拆装及更换的问题。其依次的拆装顺序是：皮带轮-轴承盖-轴承-大小轴承座-填料盒-油封-轴套-水封。拆下了坏的水封，然后换上新的水封，更后在倒序依次装个各个零部件，我们即完成了大型洗衣机水封的更换工作。

Pulley:To replace the water seal of a large washing machine, we should first know the installation location of the water seal. As mentioned above, it is installed on the drive shaft and depends on the main shaft. Find its position, then replacement is nothing more than a problem of disassembly and replacement of parts one by one. The sequence of disassembly and assembly is: pulley-bearing cap-bearing-bearing seat-stuffing box-oil seal-shaft sleeve-water seal. After removing the broken water seal, replacing it with a new one, and then installing the various parts in reverse order, we have completed the replacement of the water seal of the large washing machine. 

如若单纯从上述来看，这个大型洗衣机水封更换也并不困难，其实不然，这是因为轴承传动机构作为大型洗衣机的更为核心部件之一，其的结构相对复杂，我们如若没有专门的工具(这其中就需要门圈支撑器，力偶加长套筒，加长推进器，丝杆拔盘等)，又或者未能掌握相应的技术又以及未做好标记，那么就有可能造成水封更换的异常性，不仅未更换好，还有可能造成其它连带问题的出现。所以我们建议，如若您不具备这方面的能力，那么尽量找专业的技术工人，又或者联系厂家进行服务。

From the above point of view, it is not difficult to replace the water seal of this large washing machine. In fact, it is not. This is because the bearing transmission mechanism is one of the more core components of the large washing machine. Its structure is relatively complicated. If we do not have special tools (Among them, door ring support, force couple extension sleeve, extension thruster, screw puller, etc.), or fail to master the corresponding technology and fail to make a mark, then it may cause the replacement of the water seal Abnormality, not only has not been replaced, it may also cause other associated problems. Therefore, we suggest that if you do not have the ability in this area, try to find professional technical workers, or contact the manufacturer for service.

还有就是，不同品牌的大型洗衣机在选材用料上的差异，相应所选择的水封也是不同的，这即有品牌也有规格尺寸大小上的差异，所以我们更换的水封更好找原厂购买，再不济，也应先将拆下的水封测量好尺寸，按规格购买，以防装上不能用，又或者装不上，密封防水性不佳的问题。

There is also the difference in the selection of materials for large washing machines of different brands, and the corresponding water seals selected are also different. This means that there are differences in brands and sizes, so we better find the original factory for the replacement water seal. If you buy it, no matter how bad, you should first measure the size of the removed water seal and buy it according to the specifications to prevent the problem of poor sealing and waterproof performance.
