Vacuum pump 'stuck' phenomenon

vacuum water pump at run time, for some reason cause motor overload operation, even turn to be not moved, often used to this kind of phenomenon is called 'stuck' phenomenon. Stuck in the vacuum pump is: 1. Spring is damaged, the rotary vane bearing uneven; 2. Improper assembly, a local stress; Due to the air inlet filter loss or damage, make exterior dirt, scrap metal, such as glass crumbs fall into the pump chamber. 3. rotor, rotary vane end face and the clearance between the end cover is too small, the friction heat overheat the rotary-vane elongation or tight friction and rotary vane hardness is too big, and burrs grinding enclosed with each other, make the face produces deep scratches, the sintering. Death always occur in the rotor, rotary vane and end face or partition or between the rotor and the pump cavity, the question of which part is the key to decide the limits of a vacuum pump pressure parts, so a stuck phenomenon occurs, will pump emergency shutdown, troubleshooting, repair properly, never again run even foolhardy, otherwise very easy create vacuum pump all scrap, beyond repair.
