Examples of industrial applications of liquid film mechanical seals (2):

In response to this special working condition, the Institute of Sealing Technology of China University of Petroleum has developed liquid film sealing technology products with independent intellectual property rights through research. The cartridge double-end seal structure is shown in Figure 4-27. Among them, the medium side is a non-contact liquid film seal. Its function is to prevent latex from entering the sealed part, and at the same time, it can greatly reduce the amount of flushing water flowing into the pump. , To ensure the quality of latex products; the atmosphere side can be sealed with liquid film or contact seal, its function is to prevent the flushing water from leaking to the outside, and achieve no leakage discharge. 2002 mechanical seal

Figure 4-27 A new type of liquid film seal developed by ourselves

The new type of sealing device has the following technical advantages: it can realize the delivery of latex without leakage under any working conditions; avoid a large amount of cooling water entering the pump to affect the material properties; the shaft seal has enhanced adaptability and stable and reliable operation; The pressure of the clean water can be allowed to change within a certain range, and the sealing function can be ensured under the conditions of variable speed, variable pressure, pump evacuation, and frequent on and off. It has strong adaptability and greatly improved reliability. Industrial application results show that even if the pump is frequently started and stopped more than 6 times a day, it can still achieve leak-free operation for more than 6 months.　　979.html,
