The waterproof ring of the cylinder liner is a Wholesale NBR rubber o-rings products, and the cross section is mostly circular. Compared with the skeleton oil seal, the structure is simple. It has neither a skeleton nor a self-tightening spring. It relies on the flexibility and elasticity of the rubber itself for sealing. . When installing the water blocking ring, pay attention to the following matters:

　　(1) Wholesale NBR rubber o-rings products If the waterproof ring is too thin or the water seal groove of the cylinder liner is too deep, so that the waterproof ring cannot rise above the arc surface by a certain height after being inserted into the water seal groove of the cylinder liner. Wrap a layer of asbestos rope at the bottom of the water seal tank, coat with water-resistant calcium-based grease, then put the waterproof ring into the water seal tank, and then press the cylinder liner into the seat hole of the body.

　　(2) Wholesale NBR rubber o-rings products If the waterproof ring is too thick or the water seal groove of the cylinder liner is too shallow, and the camber surface is too high after being installed, it will not only be difficult to install the cylinder liner, but also the rubber water seal will be squeezed. Even if the cylinder liner is crushed, the rubber water seal can be evenly polished with emery cloth until it protrudes to a suitable height after being installed in the water seal groove. Then apply grease on the surface of the rubber ring, and then the cylinder liner can be pressed into the body seat hole.

　　(3) Wholesale NBR rubber o-rings products If the thickness of the waterproof ring is uneven or the depth of the water seal groove is different, and the rubber ring protrudes unevenly after installing the cylinder liner, you should carefully check whether it is the rubber ring or the water seal. If there is a problem with the slot, replace the defective part.

　　(4) Wholesale NBR rubber o-rings products Before the rubber waterproof ring is inserted into the water seal groove of the cylinder liner, the rubber ring and the water seal groove should be cleaned, and impurities and dirt should be avoided during installation.
