Common damage to mechanical seals in reactors and how to deal with them
In the process of using the reactor, damage often occurs. The most common damage to the mechanical seal of the reactor and the treatment methods are: 1. Damage to the mechanical seal 1. During the long-term use of the mechanical seal equipment, there will be The dynamic ring end face is bumped or deformed. 2. If the specific pressure of the end face of the mechanical seal equipment is too large, the mechanical seals used in the kettle will conflict and thermal deformation will occur. 3. If the sealing ring of the equipment is selected incorrectly, it will affect the pressing force of the equipment. If the pressing force of the mechanical seal of the kettle is not enough, or if the V-shaped sealing ring of the equipment is installed reversely, the sealing ring will lose its value. Some sealing effect. 4. The axis of the mechanical sealing equipment of the reaction kettle and the end face of the static ring will have a large vertical difference and miss. 5. Once the temperature of the mechanical sealing equipment is unstable and the operating pressure is abnormal, hard particles will enter the conflict pair. 6. The amount of shaft string should not exceed the target. 7. The mechanical seal will be damaged if there is leakage in the bonding or inlaid seam of the moving ring and the seam of the static ring. Second, the treatment method of mechanical seal 1. If the conflict pair is damaged, the conflict pair should be replaced, or the conflict pair can be reground. 2. Strengthen the cooling system, adjust the specific pressure properly, and take away the heat in time. 3. The device must be reasonable, and the material of the sealing ring must meet the pressing force. 4. The overhaul reactor must be stopped, and it must be re-aligned to ensure straightness. 5. Strictly control the technical target, and neither crystals nor particles should enter the conflict pair. 6. Repair the shaft and adjust the shaft to make the shaft more standardized. 7. To improve the technology of this device, the adhesive should be strong.
