1. The method of simple dynamic balance test for impeller is also very simple. After the impeller is supported, use the hand to rotate it gently, and the place that cannot reach the balance will stop to the lowest point and swing left and right. If there is a bias on the opposite impeller spot welding, increase the weight to make it balance, or use the Angle grinder to grind the welding of the bias impeller, can also achieve balance, so that the fan can be repaired for normal work. Note that in the repair process of the fan can not be spot-welded with electric welding, leaving the solder marks on the impeller, so as not to affect the balance of the fan impeller, unable to achieve the purpose of repair, resulting in greater losses.
2. If the rivet head of the impeller is worn, the worn rivet head can be returned to its original normal state by pressing the impeller body and surfacing the wheel hub with electric welding.
3. For the situation that fatigue cracks are easy to occur at the rivet hole, the whole unused new electrode can be used to weld and repair the crack, but it should be symmetrical with the impeller axis line as the center, leaving the residual welding electrode at the crack, and then repairing the relative rivet hole crack with a new electrode. The remaining electrode after welding is the same length as the remaining electrode when the symmetrical rivet is repaired. To ensure that the weight of the solder is equal. If there is no crack at the symmetrical rivet hole, the electrode should also be surfacing here to offset the new welding weight at the symmetrical rivet hole crack. The cracks can be repaired by welding according to this method of symmetrical replenishment.
According to the above method, the fan of the universal crusher can be quickly and accurately repaired, as long as you are careful, the fan wear is small, the maintenance workload can be small and will not lead to the complete paralysis of the fan.
Unlike other shredders only for a few industries, universal crusher has a wide range of applications, is also a universal agricultural machinery in the scope of agriculture, universal crusher due to the bad environment at work, the closure is not strict, and the speed is also very high, in the field sand and more will cause serious wear on the wind, so that the impeller body and the wheel rivet head fall off, And the rivet holes appear fatigue cracks. Sometimes some non-professional repairmen do not understand when repairing the fan, and if you are not careful, it is likely to completely scrap the fan.
