Filling material requirements for horizontal wear-resistant slurry pumps

The shaft seal of the slurry pump has always been the top priority in the development of the slurry pump industry. The most common one is the packing seal. Our previous article has talked about the principle of the packing seal. Here we will talk about the material requirements of the packing.
Due to the temperature, pressure, PH value of the sealing medium, and the linear speed, surface roughness, coaxiality, radial runout, eccentricity and other factors of the equipment, the filler material is required to have the following characteristics: 1. Have a certain elasticity Plasticity. Since it is to seal the slurry in the pump chamber to prevent it from leaking, it will be squeezed by the packing gland so that it can reach the maximum contact surface with the shaft, thus playing a sealing role. Therefore, its elastic-plastic requirements are better. 2. Chemical stability. 3Impermeability. Everyone understands this and no further explanation is needed. 4. Self-lubricating. Since the shaft needs to rotate when working, if the lubrication is not good, it will easily wear out. 5. Temperature resistance. 6. Easy to disassemble and assemble. This is to facilitate the replacement of fillers. 7. Simple to manufacture and low price.
