The Main Reason Of Failure Hammer(b)
Post Time: 2016-07-13
Grounded reasons are: the stator coil insulation is damaged, the stator and rotor rub iron. Such ships need to change stator and rotor, in addition to ground water or moisture caused by long drying click on it.
Sparks are generally large rotor rotor failure caused by re-finishing commutator brushes and replaced, if not enough you need to replace the rotor. After the replacement of the rotor to observe whether there is rubbing iron phenomenon, choking choking voice turned serious when rubbing iron, a slight rub and cause iron pills only to discover there will be current rise. Rub iron causes are: a fixed stator screws loose, too loose bearing, the stator casing deformation, bearing damage.
Mechanical failure was mainly no impact or lack of impact
As long as the machine does not appear idling noise, lack of momentum upon impact with the piston and the positive impact hammer each other's voice, and can be judged as positive and rubber hammer piston ring on aging, disassemble and being able to find the hammer piston end face lights up. There are attached hammer wear shorter but also caused no strike, no oil may also impact weakness. As the above conditions are not yet normal impact, or replace with a new piston ring or lack of momentum and there is a crash, it must be good to observe a large cylinder. Look for cracks or wear to the limit.
