Wood grinder used for a long time, the performance between the parts due to oxidative wear and tear, performance degradation, which gives the production of some hidden dangers, in this period is the wood mill failure prone period, if not handled in time will be more The more serious, the breakdown of the wood grinder is more common for some normal wear and tear caused by some failures, we have selected a few typical case analysis, through the analysis of the cause of the fault and solve this problem. The company is located in:

    Rivet hole fatigue cracks occur
    In response to this problem can be used for a new welding rod repair crack, but to impeller axis as the central symmetry, while the crack at the rest of the welding electrode left here, and then use a The new electrode repair the rivet hole crack symmetry, the remaining electrode after welding and repair of symmetrical rivets the same length of the remaining electrodes to ensure that the welding up the weight equal. If there is no cracks in the symmetrical rivet hole, the welding electrode should also be surfacing here to compensate for the newly compensated welding weight at the crack of the symmetrical rivet hole. Welding can be used to repair cracks through this method of symmetric back-up.

    Impeller head of the impeller is worn
    This common problem, we can be pressed through the hub and the impeller body with electric welding, in this way to wear the head of the rivet back to its normal state.

    Often impeller simple dynamic balance test
    First of all, the impeller should be supported, and then the hand should be used to make it rotate gently. If there is not enough balance, it will stop to the lowest point and swing left and right. If there is emphasis on the place on the opposite of the impeller on the spot welding, increasing the weight to balance, you can also use the angle grinder mill to offset the impeller welding marks, so as to achieve balance, so you can repair the fan to work properly It's It is very important to note that during the process of repairing the fan, welding can not be spot-welded at will and the welding marks will be left on the impeller, causing the balance of the fan impeller to be unbalanced and failing to repair the wood flour machine, resulting in greater loss .
