Cause Analysis and Preventive Measures of Water Leakage in Mechanical Seals of Water Pumps
Composition and Working Principle of Mechanical Seal for Water Pump
Mechanical seals are often chosen to prevent leakage of pumps when transporting high temperature and high pressure water. The mechanical accidents caused by leakage account for about 50% of the total maintenance of pumps. It can be seen that the reliability of mechanical seals plays a vital role in the efficient operation and prolongation of service life of pumps. Mechanical seals are generally composed of rotating rings, stationary rings, sealing rings or gaskets and elastic compensation elements. Its working principle is to make a pair of end faces perpendicular to the rotating axis stick to each other and rotate relative to each other, and maintain a thin liquid film between the end faces. With the assistance of the auxiliary seal, the end faces are subjected to the action of medium fluid pressure and compensating mechanical elasticity, and maintain a close fit degree to achieve the purpose of sealing.
