The shaft seal of the slurry pump includes an impeller seal and a packing seal. So what is the difference between these two seals? Let’s talk about it today. First of all, from a structural point of view, the auxiliary impeller seal is mainly composed of a auxiliary impeller and two packings, while the packing seal is composed of 4 packings, and there is no accessory such as a auxiliary impeller. Secondly, in terms of use, the impeller seal can be lubricated by adding butter or shaft seal water, while the packing seal can only be lubricated and cooled by adding shaft seal water. Therefore, if it is not convenient to add shaft seal water on site, it is more convenient to choose the impeller seal. In principle, the auxiliary impeller seal is a negative pressure formed by the high-speed rotation of the auxiliary impeller, which acts as a seal. When the pump stops running, the auxiliary impeller will also stop rotating. At this time, it depends on the two impellers. Root filling acts as a seal. The packing seal relies on the packing to seal whether the pump is running or stopped. Finally, from the effect point of view, the secondary impeller seal will not leak when the pump is running. When the pump is stopped, since only the packing acts as a seal, there will be leakage after the pump is stopped, and the packing seal There will be leakage whether the pump is running or stopped.
