1. Filler selection is inappropriate.

2. The honeycomb inclined pipe packing gland is not tight. As long as a certain compression force is applied, the packing will dry out and a certain radial deformation will occur. There will be ample space between the pump shaft (valve stem) and the inner wall of the packing cylinder, and then it will have a sealing effect.

3. The filler used is too fine. 4. The packing is cut too short, and the two cut faces cannot be tight.

5. The number of packing equipment turns is too small to meet the application requirements.

6. The honeycomb inclined pipe packing equipment is incorrect.

7. Improper storage of the filler or exceeding the period of use may constitute aging, dry cracking or loss of elasticity.

8. The radial cooperation between the filling cylinder and the gland cylinder is too large.

9. The practical head of the pump is too high. Honeycomb inclined pipe packing Under normal conditions, regarding the same centrifugal pump, if the speed is definite, the head will increase when the flow rate decreases. If the pressure of the internal medium increases, the original packing seal may be damaged and leakage may occur.

10. Wear of inclined pipe packing is severe.

11. The use of the honeycomb inclined pipe is too long. During the operation of the packing, it is affected by factors such as abrasion, erosion, aging, drying, temperature, etc., and gradually loses its fine function and causes leakage. This appearance is more common in packing sealing equipment.
