Specialized analysis of the abnormal camshaft response of the generator

We all know that a generator is actually a mechanical device that converts other forms of energy into electrical energy. But sometimes the incorrect use of power generation can cause damage to the generator, and sometimes even cause abnormal camshaft noise. Sometimes, when the generator is moving in the middle speed, the noise of the camshaft on the cylinder is loud and the noise is not clear at high speed; the sound of the single cylinder is constant when the oil is broken, and the phenomenon of vibration near the camshaft bearing is accompanied by vibration. So how do we solve the abnormal sound of the generator camshaft?
 
The reasons for the abnormal sound of the generator cam:
 
1. The clearance between camshaft bearing and journal is too large and loose.
 
2, camshaft bearing loosening or bearing alloy ablation, spalling or wear too large;
 
3, camshaft axial clearance is too large or camshaft bending.
 
The solution of the abnormal ring of the cam:
 
1. Make the diesel engine steer with the stethoscope on the cylinder at the most powerful speed. If the sound is strong and accompanied by vibration, it can be diagnosed as the bearing ring.
 
2, there is no change in the sound of the oil breaking test, and the throttle can be changed slowly. If the sound of the idle speed is clear, the sound sound is obvious at the middle speed, and the sound noise is weakened when the speed is at high speed, it can be diagnosed as the oversize of the axial clearance of the camshaft or the loosening of the bearing.
 
It can be seen that when we encounter the problem of the abnormal response of the generator cam, we first recall the reasons for the abnormal response of the generator cam described in our article to carry out one by one inspection so as to facilitate the quicker solution of the abnormal cam response, and also to reduce the failure of the cam to bring more damage to the Haikou generator rental.
