Pump mechanical seal dimensional inspection should pay attention to several issues

1 , lubrication
The mechanical seal faces should be properly lubricated , thus reducing wear and prolonging life , some lubricant friction heat can also be taken away . Lubricants generally assumed by the media itself , thus sealing face ( ring, stationary ring ) see spring pressure should not be too large.
2 , flush cooling
Pump mechanical seal end face of the work so that the heat generated should be promptly passed out, otherwise it will vaporize liquid film between the end faces formed by dry friction, flush cooling measures must be considered .
Generally flush with internal coolant security seals sealing medium , may also have an external water supply cooling water. Should be used in mechanical seal flushing coolant absolute guarantee of supply and flush the coolant flow, if necessary cleaned regularly.
3, the old seal update
In contrast with the new mechanical seal better than the old , but the new mechanical seal quality or choice of material is not the time , with the larger size of the error will affect the sealing effect ; sexual penetration in the polymerization medium, the stationary ring without excessive wear, or not to replace as well. Because static ring stationary ring seat for a long time in a quiescent state , the polymer and impurities deposited as a whole, played a good seal.
4 , the seal overhaul
Once the mechanical seal leakage will be eager to overhaul , in fact , sometimes sealed and not damaged , tamper seal tape simply adjust the working conditions or the seals can be adjusted to eliminate leakage. This way to avoid waste and to verify their ability to judge the fault has accumulated experience in maintenance to improve the quality of maintenance .
