Assembly method of mechanical seal shaft sleeve and mechanical seal
The assembly of mechanical seal shaft sleeve and mechanical seal is an important part of the maintenance and repair process of pump equipment. The following are detailed assembly steps:
Preparation work: Before installation, it is necessary to confirm whether the model and specifications of the mechanical seal are consistent with the equipment requirements. At the same time, it is necessary to ensure that the shaft sleeve, sealing chamber, and other related components have been cleaned and free of defects such as burrs and grooves. For rubber sealing components such as ethylene propylene and butyl, they should not come into contact with mineral oil and grease. It is recommended to use vegetable oil or soapy water for lubrication.
Installation of static ring: Place the static ring sealing ring on the static ring and install the static ring into the sealing end cover. It should be noted that the anti rotation pin should be inserted into the groove of the stationary ring to prevent the stationary ring from rotating. When installing the cover, be careful not to let the static ring touch the shaft sleeve, and the bolts should be tightened evenly in several times.
Install the dynamic ring: Assemble the rotating components of the mechanical seal onto the shaft sleeve one by one in order. If there is a shaft sleeve, it is necessary to first install the shaft sleeve onto the shaft, and then assemble the rotating parts of the mechanical seal onto the shaft sleeve.
Install the gland: Install the end cap onto the sealing body and tighten it evenly with screws. During the installation process, it is necessary to check the relative position between the moving ring and the stationary ring to ensure that they can fit together correctly.
Lubrication treatment: In order to reduce frictional resistance, lubricating oil should be applied to the contact area between the shaft sleeve, cavity, and cover of the mechanical seal installation and the auxiliary sealing ring. If rubber sealing components such as ethylene propylene and butyl are used, they should not come into contact with mineral oil and grease. In this case, it is recommended to use detergent or soap solution for lubrication.
Inspection and testing: After installation, it is necessary to manually rotate the shaft sleeve to check for any abnormal resistance or jamming. If the shaft cannot be rotated or there is significant local force after one rotation, the seal should be checked for installation issues and reinstalled if necessary.
The above is the assembly method of mechanical seal shaft sleeve and mechanical seal. It should be noted that during the entire installation process, cleanliness should be maintained to prevent impurities and dust from entering the sealed area. At the same time, it is necessary to strictly follow the manufacturer's guidance and requirements for operation to ensure that the mechanical seal can work properly and achieve the expected service life.
