1. Under normal circumstances, if the rivet head of the impeller is worn, it can be welded by welding the impeller body and the hub, so that the worn rivet head returns to the original normal state.
2 Usually, the can crusher is prone to fatigue cracking at the rivet hole. It can be welded and repaired with a new electrode that has not been used, but it should be symmetrically centered on the impeller axis, and the crack must be repaired. The lower electrode is left there, and a new electrode is used to repair the rivet hole crack. The remaining electrode after welding is as long as the remaining electrode when the symmetrical rivet is repaired to ensure that the weight of the weld is equal. If there is no crack at the rivet hole of the symmetry, the welding rod should be welded here to cancel the new welding weight at the crack of the symmetrical rivet hole. According to this symmetrical compensation method, the welding can repair the crack.
3. If the canopy crusher performs a simple dynamic balance test on the impeller, the method is also very simple. After the impeller is lifted, the hand is toggled to make it gently rotate. If the balance is not reached, it will stop at the lowest point and swing left and right. If there is a bias, you can spot weld on the opposite impeller, increase the weight to balance, or use the angle grinder to grind away the weld marks of the heavy impeller, and also reach the balance, so that the fan can be repaired and normal work. In the repair process of the fan, it is not possible to use spot welding to spot weld, and leave the weld mark on the impeller so as not to affect the balance of the fan impeller, and the purpose of repair can not be achieved, resulting in greater losses. Therefore, the operation as described above will definitely help you.
