To monitor the fault without stopping the machine, the first step is to understand the various operating parameters of the machine during normal operation of the crusher. It includes the production capacity of the mobile crusher during operation, the machine sound during operation, and the active state during operation. Only after understanding these basic states can the machine's anomalies be noticed in time. With the machine running normal state data as the basis, we must also understand the characteristics of some machines when they are abnormal. For example, sometimes the machine will have a large shaking sound due to the looseness of the screw. For example, sometimes the damage of the internal parts of the machine will result in a decrease in the production of the machine, and sometimes the damage of the machine will result in a decrease in the yield of the produced product. phenomenon. These state features require continuous accumulation of experience in the usual production process, and always pay attention to these abnormal characteristics when using the crusher, so that machine failures can be discovered and maintained in time. Of course, in addition to these measures, these professional monitoring instruments can also be used to monitor the operating parameters of the crusher. For example, fault monitoring can be performed by monitoring changes in the chemical composition of the crusher oil. When these measures are combined, the normal left turn of the machine can be ensured. The current society is developing very fast, and we need to have a better grasp of the knowledge of crushers. The mobile crusher early inspection in normal operation has long known that this preventive work can greatly reduce the downtime in production, thereby greatly improving production efficiency.
