What is the installation procedure of the mechanical seal?

What is 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 must be carried out in two major steps, pre-assembly and final assembly. 1) Pre-installation: It means to install the parts into the transmission group Grundfos mechanical seal and stop assembly. Put the moving ring sealing ring into the inner hole of the moving ring to form the moving ring assembly. Install the tension spring and push ring successively on the tension spring seat, screw the imported mechanical seal of the transmission screw into the push ring, adjust the pre-compression and shrinkage of the tension spring to form a compensating assembly type mechanical seal punching organization, and align the pin Install the moving ring assembly into the compensation buffer structure to form a 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 the stop assembly. 2) Final assembly: install the transmission components and stop components into the shaft and seal 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 shrinkage of the mechanical seal is also the specific pressure. The size of the specific pressure can be appropriately adjusted in practice. . Excessive shrinkage of the mechanical seal tension spring will affect the life of the mechanical seal, otherwise the mechanical seal is easy to leak.
