Precautions for installation of static ring assembly of hydraulic pump

No matter which kind of machine is inseparable from the correct installation of parts, so what problems should we pay attention to when installing the static ring assembly of hydraulic pump?

1、 Insert the inspected stationary ring seal ring from the end of the stationary ring, and install the static ring assembly into the gland or seal chamber. Under no circumstances should impact force be applied to mechanical seal parts or components. The pressed surface should be padded with clean paperboard or cloth to avoid damaging the sealing end face.

2、 After the assembly of the rotary transition moving ring assembly or static ring assembly, press the compensation ring by hand to check whether it is installed in place and whether it is flexible; whether the elastic opening is positioned reliably.

3、 Whether the perpendicularity of sealing end face and shaft or shaft sleeve center line meets the requirements.

4、 For the static mechanical seal, the anti rotation pin lead of the static ring assembly should be accurate. When pushing the static ring group, the pin groove of the assembly should be aligned with the pin. After pushing in place, the distance between the end face of the assembly and one end face of the seal chamber should be measured to determine whether it is installed in place;

5、 When tightening the bolts to compress the end cover, the force should be uniform and symmetrical, and the tightening should be completed in several times. It is not allowed to tighten at one time, so as to avoid deflection and even crushing the graphite ring.
