The picture shows that on June 28, the construction personnel contacted by the Ministry conducted a dry gas seal modification on a liquefied gas pump.
In recent years, Anqing Petrochemical Refinery has changed the previous single mechanical seal mode in view of the characteristics of easy leakage of the liquefied gas pump shaft seal, and successively added a new dry gas seal technology to the shaft seal of some pumps. After the liquefied gas pump is equipped with "mechanical seal + dry gas seal" series seal, the dry gas seal medium nitrogen, like the lubricant, lubricates the seal moving and static ring end faces, so that the dry gas seal always runs in the non-contact state, reducing the seal surface wear. The level of safe operation of the lifting device. At the same time, the liquefied gas leaking from the mechanical seal is discharged to the torch with the dry gas sealing medium nitrogen gas to prevent the igniting of the liquefied gas.
