Mechanical seal fire pump leakage causes and treatment methods.
1, The fire pump in the installation, the pump bolt slack leakage
Treatment: adjust the front position of the fire pump, slowly tighten the screws of the outer ring of the pump body one by one, do not tighten one screw at a time
2、The sealing surface is not flat, the liquid in the pump will flow out to the pump along the place where the seal is not tight
Treatment: provide vertical multi-stage fire pump model parameters to replace the mechanical seal
3, Mechanical seal amplitude hair wear serious, seepage and water leakage occurred
Treatment: adjust the friction position of the seal ring, take out the seal ring, and then exchange the orientation equipment, such as the seal ring on the fastening spring loss of elasticity or cracking, can remove the spring, with the appropriate diameter of steel wire or wire tied
4、The fire pump body has sand holes or rupture
Treatment: Replace the pump body of the fire pump
