Precautions for disassembly of mechanical seal equipment1

Precautions for Disassembly of Mechanical Seal Equipment

The quality requirements of mechanical seals are very high, and disassembly also requires great attention of mechanical seals. Why do you say this? After reading the following introduction, you will understand the difficulty. Whether it is installation or disassembly, it must be strictly carried out in accordance with the requirements, and any errors may cause system abnormalities. So what are the precautions for disassembling the mechanical seal equipment, and then I will introduce it to you. Equipment of mechanical seals: 1. The equipment environment of mechanical seals must be clean, there is no sand, dust, etc. around the mechanical seals, and the sealing surface must also be kept clean; 2. Generally speaking, the equipment error of the gland cannot exceed 0.05 mm, the gap error of the mechanical shaft seal between the gland and the shaft or the shaft jacket cannot exceed 0.01 mm, otherwise the seal will not be tight; 3. The tension of the mechanical seal spring must conform to the equipment rules, exceeding or missing conditions Neither can appear, and the error request is within 2 mm. If the tension spring is too long, it will increase the conflict and cause wear, and if it is too short, it will cause insufficient specific pressure and cause the seal to fail. 5. It is forbidden to hit or hit during the equipment process, so as to avoid the mechanical seal being damaged due to conflict and failure of the seal; 6. During equipment, the surface in contact with the seal should be coated with a layer of clean mechanical oil, so that the equipment can be smoothly installed. Disassembly of mechanical seals: 1. Be careful when disassembling the mechanical seals, and do not allow the use of rough means, such as hammering, to avoid damage to the sealing components; 2. If there is dust on the sealing equipment, it should be After cleaning and maintenance, proceed to the next step of disassembly; 3. If the mechanical seals are used at both ends of the pump body, take care of each other when disassembling and installing; 4. If the mechanical seals are pressurized after operation If the cover is loose, replace the dynamic and static ring parts as soon as possible, instead of re-tightening it, otherwise the movement track will change due to the conflict, resulting in damage to the seal on the touch surface. After the introduction of the precautions for disassembling the mechanical seal equipment above, we have a better understanding of the mechanical seal. As can be seen from the above, installation and disassembly require great care, there are certain difficulties, and it is necessary to adhere to small mistakes. Therefore, the editor advocates that if you are not very sure, you should still ask a professional master to carry out the work.
