Description

TECHNICAL FIELD

[0002] City drainage pump station bears the flood prevention and transportation function of rain and sewage. In the water pump equipment, the filler is arranged at the rotating shaft. The working principle of the filler is that the shaft surface is very uneven in the microscopic case, and the filler can only be partially attached. Therefore, there is a small gap between the filler and the shaft, like a maze. The medium is intercepted multiple times in the maze, thereby achieving the sealing effect. When the medium with pressure passes through the shaft surface, the medium is throttled multiple times, relying on the "labyrinth effect" to achieve sealing. The attachment and friction of the filler and the shaft surface are also similar to sliding bearings, and sufficient liquid should be used for lubrication to ensure that the sealing has a certain service life, that is, the so-called "bearing effect".

[0003] And the packing selected as the filler is some fibrous material, which can adjust the degree of compaction of the packing by using the gland. Since the packing is in direct contact with the rotating shaft, it is inevitable that some wear will occur over time, so the tightness of the gland needs to be adjusted regularly. If it cannot be adjusted in time, the packing will gradually wear out, affecting the sealing effect, and serious accidents such as leakage may even occur. However, the current packing is mainly tightened manually, and the manual tightening method has the following problems: time-consuming and labor-intensive, high labor intensity, and poor tightening effect.
