Imported mechanical seal

Imported mechanical sealImported mechanical seal is an oil seal device for rotating machinery. Such as centrifugal pumps, centrifuges, reactors and compressors and other equipment. Since the transmission shaft runs through the inside and outside of the equipment, there is a circumferential gap between the shaft and the equipment. The medium in the equipment leaks out through the gap. If the pressure in the equipment is lower than the atmospheric pressure, the air leaks into the equipment, so there must be a shaft seal device to prevent leakage. There are many types of shaft seals, and the mechanical seal has a small amount of leakage And long life and other advantages, so in the world today, mechanical seals are the most important shaft sealing method for these equipment. Mechanical seals are also called end seals. Precautions when disassembling imported mechanical seals: a. Be careful when installing and disassembling mechanical seals. It is strictly forbidden to use hand hammers and flat shovel to avoid damage to the sealing elements. If the fouling cannot be removed, it should be cleaned and then disassembled. b. If mechanical seals are used at both ends of the pump, take care of each other during assembly and disassembly. For the mechanical seal that has been in operation, if the gland is loose and the seal moves, the dynamic and static ring parts must be replaced and should not be re-tightened for continued use. Because the original running track of the friction pair will change after the loosening , The sealing of the contact surface is easily damaged. The reason for the failure of the imported mechanical seal: the failure of the mechanical seal is generally caused by abnormal leakage, abnormal wear, abnormal torque and other phenomena before it is known to people. The reasons for the failure are roughly as follows: 1. The design and selection of the mechanical seal is incorrect. 2. The quality of the mechanical seal is not good. 3. The accuracy of the machine using or installing the mechanical seal cannot meet the requirements. 4. The machine is running and operating incorrectly.
