In the long process of usage, the sand washing equipments can not work normally as before because of some external causes which will influence the production of the machine. Hongxing engineers have listed some of the possible problems according to our years of experience.Firstly, the surface of the iron core of become rusting. At this time, the user has to polish the rust with abrasive paper and then coat with insulating paint.Secondly, the iron loss of the motor increases and the temperature of the motor is too high. After long term use, the bearing of sand washing machine will be seriously abraded which will cause the damage of the surface of the iron core and the short circuit of the silicon steel sheet of the sand washing machine. At this time, the user should remove the short circuit of the silicon steel sheet, and then clean it before coating with insulating paint.Thirdly, the joint part of the iron core and the machine base becomes loose. For this case, the user can fasten the positioning screws.Of course, the above mentioned problems are a part of the possible problems during the operation of sand making machine. If you still have any other questions about the operation and usage of the sand washing machine, please contact us without hesitation, we will supply you the most satisfactory answers.According to the actual situation of the sand making industry, Hongxing has adopted the advanced technology to develop the new type high efficiency sand washing machine which features in large processing capacity, high cleanness and small sand loss. However, sand washing machine also needs inspection and debugging before putting it into use.1. The user had better inspect whether there is any loose bolts on the joint parts so as to guarantee the safety and stability of each part of the machine.2. The operator should add lubrication oil to the jointing parts and bearings of the machine to make sure the bearings can operate flexibly and continuously. At the same time,...
