As a mechanical industrial product, chemical pumps are used in practice. The occurrence of product defects is a common product question. Some operators may have a certain understanding of the product, and use their common sense to repair chemical pump products. The editor now summarizes the misunderstandings in the repair of chemical pump products to help users deal with the problems of the products:
Excessive shrinkage of the tension spring not only fails to achieve a very good sealing effect, but simply causes greater friction and accelerates wear. Excessive tightening makes the tension spring lose its ability to adjust the end face of the moving ring, causing the seal to fail.
Too tight the moving ring seal will not only form the seal ring and accelerate the damage of the shaft sleeve, it is very easy to leak and reduce its service life, and the too tight moving ring seal will increase the resistance to the axial adjustment and movement of the moving ring. As a result, chemical pumps cannot be adjusted usefully when there are more frequent changes in working conditions; secondly, a too tight moving ring seal will cause excessive fatigue of the tension spring, which is easier to damage, and after all, a too tight moving ring seal will form a ring The deformation of the sealing ring will eventually affect the sealing effect of chemical pump products.
Generally speaking, the static ring seal of a chemical pump is in a stopped state under normal conditions. A moderately tighter static ring seal will have a better sealing effect, but excessive tightening will not only cause the static ring seal to be excessively deformed and affect the seal In addition, the raw materials of static ring seals are mostly graphite, which is usually brittle. Excessive force can easily cause breakage, and it is difficult to install and disassemble the static ring seal ring, and the static ring is also easily damaged.
In mechanical seal leakage, the leakage between the sleeve and the shaft is one of the more common leakage faults. The average operator may think that the leakage between the shafts means that the impeller lock nut is not locked. In fact, there are many factors that cause the occurrence of this problem with regard to the leakage between the shafts. The pads between the shafts are invalid and offset, there are impurities in the shafts, the shaft and the shaft sleeve have large shape and position errors, and the contact surface is damaged. There are gaps between parts, and many factors such as excessively long shaft head threads will cause leakage between shafts. Over-locking the lock nut will only cause premature failure of the inter-axis pad. On the contrary, properly lock the lock nut so that the inter-axis pad always maintains a certain degree of elasticity. During work, the lock nut will take the initiative to lock the shaft to keep the shaft between the shafts. Good sealing condition.
Theoretically speaking, the effect of using new mechanical seals is better than using old mechanical seals. However, in practice, improper selection of the quality or raw materials of the new mechanical seals, and large errors in cooperation dimensions will affect the use of mechanical seals. negative influence. In polymeric and permeable media, if the static ring is not excessively worn, it is still better not to replace it. Since the static ring is in a stopped state for a long time in the static ring seat, the polymer and impurities are deposited as a whole, which has a better sealing effect.
Regarding some users, do not rush to disassemble and repair the mechanical seal when it is found to be leaking. Since the seal is not damaged, it may be due to changes in the environmental conditions of the chemical pump. At this time, you only need to adjust the working condition of the chemical pump or adjust appropriately. Sealing can eliminate leakage.
