Cartridge Mechanical Seal Models And Sizes

The selection and determination of the model and size of the containerized mechanical seal, first of all, needs to be clear that the mechanical seal is a device to prevent fluid leakage, mainly composed of at least one pair of end faces perpendicular to the axis of rotation, which are kept in contact and slide relative to each other under the action of fluid pressure and the elastic force (or magnetic force) of the compensation mechanism, and the cooperation of the auxiliary seal. There are many types of mechanical seals, including but not limited to oil seals, and their models and sizes must match to meet different application requirements.

Model selection: The model selection of mechanical seals is based on its scope of application and working conditions. For example, the HU1 type mechanical seal complies with ISO3096DIN24960 and GB6556 standards and is suitable for a variety of working conditions, while the HU3 type complies with DIN24960 and GB/T6556-94 standards and is suitable for sewage pumps, chemical pumps, heat circulation pumps, etc. The HU5 type mechanical seal is suitable for single spring and single end face structure, while the HU7 type has the characteristics of unbalanced and conical spring structure. In addition, there is the HUU803 type mechanical seal, which complies with DIN24960 and GB/T6556-94 standards, is an unbalanced, multi-spring structure double-end design.

Size considerations: The choice of size is also important because it directly affects the performance and applicability of the mechanical seal. For example, the diameter of the B-type mechanical seal is about 24, while the diameter of the U-type mechanical seal is about 20. This dimensional information is essential to ensure that the mechanical seal can be properly installed and perform its functions.

When choosing a cartridge mechanical seal, other factors need to be considered, such as the choice of auxiliary seal material (such as rubber O-ring or PTFEV ring), and whether a specific balanced design is required. Ultimately, the type and size of mechanical seal to be selected should be determined based on the manufacturer's product catalog and actual application requirements.
