How about the installation procedure of the mechanical seal?

The structure of the mechanical seal is different, and the installation method is also different. However, almost all mechanical seals are carried out in two major steps: pre-assembly and final assembly. 1) Pre-installation: that is, to install the parts into the Grundfos mechanical seal and stop assembly of the transmission group. Insert the moving ring sealing ring into the inner hole of the moving ring to form the moving ring assembly. Install the tension spring and the push ring on the tension spring seat successively, screw the drive screw inlet mechanical seal into the push ring, adjust the pre-compression and compression amount of the tension spring, form a compensation buffer type mechanical seal punching structure, and align the pins Put the moving ring assembly into the compensation buffer structure to form the transmission assembly. Put the static ring sealing ring on the static ring, put it into the static ring sealing chamber, and evenly press the cover to form a stop assembly. 2) Final assembly: put the transmission components and stop components into the shaft and the sealing chamber to complete the installation of the mechanical seal. Use a depth vernier caliper to measure the distance between the end face of the dynamic ring seal and the end face of the seal cavity and the distance between the end face of the static ring seal and the end face of the end cover. The actual compression of the mechanical seal is also the specific pressure. The size of the specific pressure can be adjusted appropriately in practice. . Excessive tightening of the mechanical seal spring will affect the life of the mechanical seal, otherwise the mechanical seal is easy to leak.
