Precautions for disassembly of mechanical seal equipment

Precautions for disassembly of mechanical seal equipment Mechanical seal equipment quality requirements are very high, and disassembly also requires great attention to mechanical seals. Why do you say that? After reading the following introduction, you will understand the difficulty. Regardless of whether it is equipment or disassembly, it must be strictly in accordance with the request. Any error may cause the system to be abnormal. So what are the precautions for disassembling mechanical seal equipment? Next, I will introduce you. Equipment of mechanical seals: 1. The equipment environment of mechanical seals must be clean, and there is no dust, dust, etc. around the mechanical seals, and the sealing surface must also be clean; 2. Generally speaking, the equipment error of the gland should not exceed 0.05 Mm, the gap error of the mechanical shaft seal between the gland and the shaft or the shaft sleeve cannot exceed 0.01 mm, otherwise the seal will not be tight; 3. The tension spring contraction of the mechanical seal must conform to the equipment rules and exceed or lack 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 abrasion, and if it is too short, it will cause insufficient specific pressure and cause the seal to fail; 4. After moving the ring equipment, ensure that it can move sensitively on the shaft, and press the moving ring to the tension spring. Bounce back; 5. Do not hit or hit during the equipment process to avoid the mechanical seal conflict and damage and seal failure; 6. The surface of the equipment that touches the seal should be coated with a layer of clean mechanical oil in order to smooth the equipment. Dismantling of mechanical seals: 1. Be careful when disassembling mechanical seals. Rough means such as hammer strikes are not allowed to avoid damage to the sealing elements; 2. If there is dirt on the sealing equipment, it should be After cleaning and maintenance, proceed to the next step of disassembly; 3. If mechanical seals are used together at both ends of the pump body, they must take care of each other when disassembling and installing; 4. If mechanical seals are under pressure after operation If the cover is loose, it is necessary to replace the moving and static ring parts as soon as possible instead of tightening it from the beginning. Otherwise, the movement track will change due to the conflict, and the seal of the touch surface will be damaged. After the introduction of the precautions for disassembly of mechanical seal equipment, we have a further understanding of mechanical seals. It can be seen from the above that equipment and disassembly are required to be very careful, there are certain difficulties, and it is necessary to insist on small errors. Therefore, the editor advocates that if you are not very sure, you should still ask a professional master to do the work. Keywords: mechanical seals, mechanical seals, mechanical shaft seals
