Post-maintenance method of packing
The workshop is a place to stand and work for long periods of time, so the use of anti-fatigue MATS is very important for the health and productivity of employees. The following is a discussion about the necessity of using anti-fatigue MATS in the workshop and the types of options available on the market: anti-fatigue floor MATS combine various functions: fatigue relief, high elasticity, shock resistance, etc., can effectively prevent impact and fatal injuries, and are very durable for industrial and harsh environments. The shape of its bottom and surface is designed for workers to stand for a long time, which can greatly reduce the fatigue and pain caused by prolonged standing on the legs.

1. Once the packing is assembled, it can be put into operation. Before starting the vehicle, it's important to perform a slow manual test run (cranking) to ensure everything is functioning properly. During operation, if excessive torque is detected, it may be due to over-tightening of the packing gland. In such cases, loosen the gland bolt slightly until the frictional resistance decreases and the seal remains leak-free. This applies to various types of packing, including graphite, asbestos, PTFE, cotton, high-water-based, and aramid packing.
When starting the packing, if you notice high friction torque and prolonged heating in the stuffing box, it could indicate insufficient lubrication or excessive pre-tensioning. Adjustments should be made accordingly, and if allowed, maintain a small amount of leakage to provide cooling and lubrication. For most centrifugal pumps handling non-hazardous media, a slight drip leakage is normal during operation and helps keep the seal in good condition.
2. After actual operation, regularly monitor the packing for any signs of leakage or abnormal temperature in the stuffing box. If the braided packing shows irregularities, make immediate adjustments. If the leakage exceeds acceptable limits, tighten the gland gradually—no more than one full turn at a time. Always ensure that the allowable leakage level is maintained to prevent sudden increases in friction heat, which could damage the packing. This advice applies to graphite, asbestos, PTFE, cotton, high-water-based, and aramid packing types.
3. For dynamic seals, especially those with high linear speed, continuous cooling water or lubricant should be applied. This is an effective method to enhance sealing performance and extend the lifespan of the packing material.
4. Storage Precautions for Packing
1) Sealed packing should be stored in a cool, well-ventilated area. Avoid direct sunlight exposure, as this can cause degradation of the material. Do not store packing near corrosive substances like acids or bases, nor in high-temperature or humid environments, as these can affect its performance and durability.
2) During handling and storage, take care to avoid contamination from sand or dust. If impurities get stuck on the packing, clean it thoroughly before installation to prevent damage to the shaft surface and ensure proper sealing performance.
3) For packing used in nuclear power plants, additional precautions are necessary. Make sure the packing does not come into contact with materials containing chloride ions, as this can lead to corrosion or failure. This guidance applies to graphite, asbestos, PTFE, cotton, high-water-based, and aramid packing types.
Proper maintenance and storage of packing materials are essential to ensure long-term reliability and safety. Always follow manufacturer recommendations and local regulations when handling and installing different types of packing. Regular inspection and timely adjustment can significantly improve system performance and reduce downtime.
