Professional explanation of filling skills of hollow ball filler
When filling the polyhedral hollow ball filler, it is better to take a wooden stick with the same length as the shaft for the braided polytetrafluoroethylene end ring, wind the braided polytetrafluoroethylene on the wooden stick, and then cut it with a knife. The incision is better to be inclined. A wooden two half shaft sleeves with the same length as the filler cavity are combined on the shaft to push the braided filler into the deep part of the cavity, and use the gland to apply a certain pressure on the wooden shaft sleeve to make it pre concentrated.
Take care to keep the braided packing flat at the bottom of the chamber. The mixed cement filling must be pressed with a wooden shaft sleeve while being injected. Finally, the braided polytetrafluoroethylene shall be pressed on the outside of the packing chamber to tighten the gland evenly. At the same time, the spindle shall be rotated by hand to make the compression force of the filled multi sided hollow ball filler tend to parabola distribution. Later, the gland shall be slightly loosened to complete the filling.
Carry out operation test, just start the operation. The disclosure is mainly based on intermittent leakage. When the disclosure increases, properly tighten the gland bolts. In case of excessive heating, loosen the bolts. After the operation is normal, the disclosure is basically stopped. After 60h of trial operation, open the sealing chamber of the hollow ball packing on many sides to watch, and the braided PTFE end ring shape remains intact.
The mixed soft packing has no drop phenomenon, and there is no sign of wear on the shaft. As the packing gland can maintain no leakage for a long time, take care of the environment. It is convenient to protect and maintain. When the disclosure is large, the multi sided hollow ball filler can be injected without stopping, which delays the continuous working time of the pump and saves labor and repair costs.
