Hydraulic Seals

The Unsung Heroes of Fluid Power: A Deep Dive into Hydraulic Seals Hydraulic seals are mission-critical components that separate fluids, block contaminants, and maintain the pressure essential for hydraulic systems to function efficiently. Operating under extreme pressure, temperature, and dynamic movement, selecting the correct seal is vital for preventing system failure, reducing maintenance costs, and […]

A Method for Identification of PTFE Gland Packing

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 […]

How Does Work Gland Placking?

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 […]
