Before designing the agitator mechanical seal, you should design all the conditions, you must know the required PV value, and also know the shape and volume of the device used. At connection with these conditions, it is also necessary to know the size of the frictional power, which will also affect its own life, which will affect the consideration of the material to be used; structure and strength; reliability and stability; materials and prices.
The installation of the agitator mechanical seal is important for the user because the seal is not easy to enter some dust, while the accumulation of dust is easily causing the equipment to malfunction. So before installation, some precautions not only need to attract everyone, but in practice, it is necessary to operate with these installations.
1. In order to facilitate the disassembly and assembly, a short-tunal coupling is generally installed between the mixing and shaft and the drive shaft.
2. The agitator mechanical seal can be installed in the mechanical seal manufacturer or repair shop in the sealed manufacturer or the maintenance work. The installation of the product needs to be installed in accordance with the instructions.
3. The mixture is rarely operated, so the agitator mechanical seal of the kettle is a gas, usually in a dry conflict state, and the end face has a large abrasion because the gas permeability is strong, and the sealing data is high. In order to smooth and cool the sealing end surface, the fluid dynamic double-end face seal is generally selected as the kettle seal, and smooth, cooling, and smooth, smooth, and smooth. Single-end seals are only used for low pressure contrast or inappropriate.
4. Mix the shaft pair and the lower ends there are mixed paddle, so the agitator mechanical seal swings and oscillations are large, so that the ring and the static ring do not have good fit, usually the need for mixing and shaping bottom bearing or center bearing. In order to reduce the impact of the shaft rocking and oscillation on the sealing, the bearing is added to the sealing, and there is a good floating in the thread and the static ring.
