Horizontal slurry pump in the selection of packing seal when there are any precautions, today we continue to introduce.

In the selection of materials, self-lubricating filler should be selected to obtain a better sealing effect, such as flexible graphite or polytetrafluoroethylene.

In order to ensure the lubrication of the packing seal, the general packing is often impregnated with lubricant, and the lubricant is gradually consumed during 

use, not only the lubrication performance is reduced, but also the volume of the packing will be reduced, so that the compression force is reduced, so the packing

 seal should be tightened regularly to ensure the compression force and lubrication. For packing seals with quality requirements, the packing box should be 

designed with added lubricants.

During the working process, the packing will wear out. Wear is related to the compression force and lubrication state, usually by the end of the gland due to

large compression force, wear is larger, incorrect filling will also lead to rapid wear. Excessive wear will lead to seal failure, so pay attention to timely replacement 

of filler.

The size of the packing and packing box is related to the size of the shaft and the medium pressure, and can be selected according to experience and relevant 

reference charts. In addition, filling filler must be carried out with special tools and in accordance with operating procedures. Unreasonable filling is one of the 

main reasons for seal failure.
