1.Wrap the graphite packing on a pipe with the same diameter as the shaft, wind it tightly but not stretch it, and cut it after alignment. Note: Do not use the method of surrounding the stuffing box to measure the length. Cut off the first sealing ring, try to fill the stuffing box just right, and make sure that the joint is tight and there is no gap. Then use the first sealing ring as the standard to cut other sealing rings. If the sealing ring is cut on a flat surface, the end surface should be inclined to compensate for the deformation after winding. If the packing material is soft and easy to wear, you can wrap tape around the cut and cut on the tape surface. You can decide whether to remove the tape according to the shape of the joint.

3. After the sealing ring is installed, tighten the gland bolts by hand. A certain amount of leakage must be maintained when starting, otherwise it will cause the packing to heat up and burn. Then tighten the nuts evenly in turn until the leakage rate reaches the qualified standard. Water seal ring: It is recommended to install a water seal ring as much as possible, and inject lubricating oil into the stuffing box through the water seal ring to lubricate the shaft and packing. The position of the water seal ring must be aligned with the injection hole.
