What is the impact of a mechanical seal positioning lock plate that hasn’t been loosened on turning the pump shaft?
Thread Content
There is a feed pump for which it is not easy to turn the shaft by hand. If the mechanical seal locking plate is not released, can the shaft still be turned at this time? How much of an impact does whether the positioning locking plate is released or not have on the ability to turn the pump’s shaft?
That’s how it is when using set screws for positioning; if keys are used for positioning, either it won’t open or the shaft seals will be completely ruined!
Operations must be carried out strictly in accordance with the installation and usage instructions; after installation, release the positioning piece and tighten the screw for the locking piece. When turning the shaft without releasing the lock plate, there is sticking; during operation, there is mechanical interference, which causes frictional heating and damages the mechanical seal
