The cause of the fire pump mechanical seal leakage and measures

The cause of the fire pump mechanical seal leakage and measures 2019 - 10 - 9 fire pump in the practical application, the mechanical seal leakage would happen, then need to check the specific reason, then its solution, as you say below the cause of the fire pump mechanical seal leakage and measures. Reason 1: the fixed screw loose, make the spring. Measures: fastening screws or reset spring. Reason 2: the impurities, foreign bodies, or medium existence of crystallization, influence the axial movement of ring. Measures: to eliminate impurities, foreign bodies, and crystallization, it is recommended that clean packing element. Then need to do regularly impurity detection. Reason 3: spring pressure is insufficient, or lose their elasticity. Measures: to adjust the amount of spring compression or in spring. Reason 4: static ring assembly skew. Measures: heavy fire pump use static ring. Reason 5: dynamic or static ring end surface corrosion and wear or scratch. Measures: fixed ring and static ring, to fix suggested replacement. Reason 6: shaft sleeve machining precision and the finish is not enough, influence the axial movement of ring. Measures: recommend replacing sleeve, to fine the eligibility criteria. Reason 7: ring seal assembly skew roll deformation or corrosion. Measures: reshipment or replaced with a ring of fire pump seal. Looked at the above content, believe everybody already knows the cause of the fire pump mechanical seal leakage and measures.
