Identification PTFE Gland Packing The most critical factor affecting the function of PTFE packing is its weaving density. However, weaving itself has a strong artistic quality, and the weaving density is often difficult to reflect with numerical values. Experience tells us: the tightly woven PTFE packing can not only resist wear and kneading, but also […]
After the packing is loaded into gland, the packing is compressed by the gland shaft. Due to the plasticity of the filler, it generates radial force and is in close contact with the polished rod. At the same time, the lubricant in the sealing packing is squeezed out, forming an oil film between the contact […]
