When the reactor equipment leaves the factory, in order to ensure that the mechanical seal dynamic and static rings are not damaged, the dynamic and static rings are separated. After the equipment is lifted into place,

Firstly, remove the tape and clean the sealing surface of the dynamic and static rings. There should be no oil stains or stains, and the sealing surface must be clean. If it is not clean, it is easy to leak. After wiping it clean, apply lubricating grease to the sealing surface and place a pry bar symmetrically on one side. Special attention should be paid to not colliding the sealing surface of the moving ring and the sealing surface of the stationary ring when pushing the component down, in order to avoid damaging the sealing surface. Tighten the two top screws on the upper moving ring, and then slowly pry the two pry bars on both sides at the same time. Be sure to pry downwards slowly, and be sure to hold the graphite ring tightly. Don't fall it off, as it is easy to break and feel that the pry bars won't move. If the force is not enough

Adjust it again, repeat the cycle, loosen the top screw, lower the locking nut a little further, tighten the top screw, and then put the pry bar in and slowly pry it, paying attention to the O on the moving ring Press the circular ring into the slot between the moving ring and the shaft, and press the metal pressure ring of the pressure ring onto the moving ring according to the slot position. After pressing it to the bottom, use an Allen wrench to loosen the screws, loosen the top four screws, slowly lower them, and see that there is no gap. Tighten the four screws of the top shaft, and even tighten the top four screws. When you see that the stainless steel ring rises nearly 0.5 centimeters, it proves that the mechanical seal has been pressed in place. Rotate the motor shaft by hand to slowly rotate the mixing shaft a few times. The rotation should be flexible and normal, without any jamming or other abnormal phenomena. Then you can rotate and test it. After the test, check if there are any leaks here. Just press the screw evenly, the gap must be even.
