The installation process of the machine seal needs accurate operation to ensure the correct docking of the sealing element, the smoothness of the sealing surface and the ability to withstand high temperature, high pressure and other working conditions during the working process of the evaporator. Before installation, the clean working environment and the installation position of the machine seal need to be checked to ensure that the installation position is clean without oil stains, dust, sundries and the like, so as to avoid the entry of these substances into the sealing surface and affect the sealing effect. The steps of installing the evaporator machine seal include installing the static ring, installing the dynamic ring, assembling the spring system, installing the sealing surface, checking the centering condition, checking the installation of the sealing element and tightening the fixing device.

Appropriate tools should be used to tighten the bolts according to the specification to avoid damage caused by improper operation. Before installation, if the positioning of the fixing device is not performed, the operator will spend a lot of time in installing, aligning and fixing the device and then tightening the bolts. After installation is completed, because of the high-strength work of the machine seal, loosening may exist, which affects the work.
