Installation of the mechanical seal is fixed by two fixing screws on the spring seat and the shaft. When tightening the fixing screws, the working length of the spring must be guaranteed.
Second, the use of mechanical seals
1. Before starting the main machine, check the attached device of the mechanical seal and check whether the cooling and lubrication system is complete and smooth.
2. The material pipeline should be cleaned before starting to prevent rust impurities from entering the sealed cavity.
3. Move the coupling by hand to check whether the shaft rotates easily. If the movement is heavy, check whether the relevant installation dimensions are correct.
4. Before normal driving, a static pressure test is required to check the sealing effect of the end face of the mechanical seal, the seal ring and the seal end cap. If there are any problems, check and solve them one by one.
5. Before the host starts, the sealed cavity should be filled with liquid or sealed medium. If a separate sealing system is to be started, the cooling water system must also start to circulate.
6. Before normal use, perform normal pressure operation and observe whether the temperature rise of the sealed part is normal and whether there is leakage. If there is a slight leak, you can run in for a period of time to make the end surface fit more evenly, until the leakage is gradually reduced to normal. If the leakage does not decrease after 1 to 3 hours of operation, stop and check.
7. Under normal operating conditions, the boost and temperature rise can be carried out slowly, and pay attention to the temperature rise and leakage of the end face. If everything is normal, it can be put into production. When stopping, stop the main engine first, and then stop the cooling and lubrication system.
