Cartridge mechanical seal

Cartridge type mechanical seal Cartridge type mechanical seal is a combination of 7 main parts such as moving ring, static ring, spring, auxiliary sealing ring, shaft sleeve, gland static sealing gasket, etc., into an assembly, which can also be called assembly Type mechanical seal (Cartridge Sea1). Sometimes called cassette seal. Cartridge type mechanical seal has been assembled into a collection. Therefore, the installation on the body is more convenient, faster, and the seal is reliable. It is well received by users at home and abroad. It is the direction of the development of mechanical seals in China in the future. Cartridge mechanical seals are generally balanced mechanical seals, as shown in Figure 1 for the AIG318 type The structural feature of the cartridge mechanical seal is that all parts are combined into one, the spring does not contact the material, the balanced type, internal flow, and the positioning block can adjust the spring compression. Considering that it can be easier to compensate when the dynamic/static ring wears. Designed with a dynamic ring seal. The shaft sleeve and the gland are indispensable parts of the cartridge mechanical seal, through which all the mechanical seal parts can be combined. The gland can be connected with the body. When the temperature of the material is too high or too low When flushing is needed, the gland can be processed into flushing holes to meet the needs of the process. The set screw is also very important, and it is the main part to overcome the friction between the dynamic and static rings. The head of the set screw of AIG3l8 is engraved with a spiral groove, which can be Prevent the screw and shaft from slipping and loosening. 318i is a waist-shaped static ring gland. There are two gland bolts, which can be directly replaced. The original sealing packing is used for sealing. And there is no need to modify the original equipment. When the mechanical seal needs to be flushed, you can choose 318A gland with flushing holes, 4 gland bolts, and meet the requirements of API standards. The cartridge mechanical seal can ensure the accuracy of the seal in the working state, Installation is convenient and fast, eliminating human installation errors. Features: The seal has a short axial size and a compact structure. It is especially suitable for applications where the radial size is not tight and the axial size position is restricted. Both the inner and outer end faces adopt a balanced structure. Durable and stable. Scope of application: Pressure: ≤2Mpa Temperature: 0-250℃ Speed: 0-100rmp Medium: Strong corrosive, acid, alkali, salt and organic solvent Shaft diameter: Ф30-160
