It is a well-known fact that sand making machines are widely used. The use of sand making machine must be maintained. In order to reduce the maintenance cost of sand making machine, it is necessary to master the maintenance technology of some sand making machine. So, what are the necessary maintenance techniques for the sand making machine in the process of use? Basically, it can be summarized as the following three points.
1. The lubrication system of the sand making machine should use the special grease of Mobil vehicle or 3 # lithium base grease. When the sand making machine has been working for 400 hours, an appropriate amount of grease should be added, which can play the role of lubrication of the sand making machine. When the sander has been working for 2,000 hours, the spindle assembly should be opened to clean the bearings. Under normal circumstances, when the workload of the sand making machine reaches 7200 hours, the new bearings should be replaced.
2. Regularly observe the wear conditions inside the VSI sand maker. The wear level of the feeding pipe, cone cap, impeller upper and lower runner lining plates, circumferential guard plates, wear-resistant blocks and other parts in the center of the sand making machine is relatively high. These parts of the sand making machine should be replaced to avoid safety problems when the sand making machine works due to component wear. When some key parts are checked, if you can’t repair it yourself, don’t assemble it by yourself, you should find a professional maintenance person for inspection. Such as: the impeller inside the sand making machine.
Third, the transmission belt of the sand making machine should be properly adjusted in tension, the purpose of doing so is to ensure that the load on the belt is uniform. When driven by dual motors, the triangle tapes on both sides should be grouped and matched so that the length of each group is as consistent as possible. Should be adjusted so that the current difference between the two motors does not exceed 15A
For the above three points, it can be said that it is a necessary knowledge of the sand making machine. Mastering the necessary knowledge of the sand making machine maintenance can make the sand making machine do more with less in the process of work, reduce the down time of the sand making machine, and greatly extend it. Working hours of the sand maker.
