Detailed explanation of the requirements for the use of mechanical seals

During the use of mechanical seals, in order to ensure the standard and safety of the use of the seals, we need to understand the use requirements of the equipment in detail, so as to ensure the safety and performance of the seals.

(1) When the temperature of the conveying medium is too high, too low, or contains impurity particles, flammable, explosive, or toxic, corresponding measures such as blocking, flushing, cooling, and filtration must be taken.

(2) Turn the car by hand before running, pay attention to whether the torque is too large, whether there is friction and abnormal sound.

(3) Pay attention to the direction of rotation, whether the coupling is centered, whether the lubricant oil in the bearing is added properly, and whether the piping is correct.

(4) Before operation, first open the medium and cooling water valves, check whether the gas in the sealed cavity is fully discharged, and prevent leakage caused by static pressure, and then start the machine.

(5) Whether the work is normal and stable after driving, whether there is abnormal torque caused by the rotation of the shaft, as well as abnormal noise and overheating.

In short, complying with the use requirements of the mechanical seal can better ensure the use efficiency and safety of the equipment, and better prolong its service life.
