Gear pump seal with a variety of methods, mainly divided into contact, non-contact, modular, fully enclosed seal four categories. In general, the contact seal seal surface contact, you can eliminate the gap or make Sealing gap to reach the minimum value, therefore, can achieve high sealing performance, but limited by the friction and wear of the material, suitable for sealing surface line speed is relatively low occasions.Contact seal by contact parts can be divided into radial (circumference ) Seals and axial (face) seals; face seals, often referred to as mechanical seals, are currently the most widely used form of seal for industrial pump products. Non-contact seals Sealed seals are not in direct contact, free of mechanical friction and wear, For high linear speed applications, long working life, but poor sealing performance, reasonable design can achieve zero leakage. Non-contact seal includes labyrinth seal, floating ring seal, screw seal and end face power controlled membrane seal. Seal can be both the advantages of contact and non-contact seal, to meet the requirements of high-parameter seal, but the structure is complex, the system is huge, so the general industrial pump does not use such forms of sealing Sealed closed machine is sealed with a case or a cover all the machines closed, the advantage of fully enclosed pump is no shaft seal, usually used to seal flammable, explosive and highly toxic media. According to seal in the pump products The use of features, the use of seals, the characteristics of the mechanism, the basic structural specifications and the specific structure of the fluid seal can be detailed classification.
