Analysis about Failure and Common Program of Crusher

If we want to improve the efficiency and reduce the production cost of the jaw crusher and mobile crusher, we have to carefully analysize the causes of the failure of the crushing machine. The purpose of failure analysis not only lies in the discrimination of the nature of the faults and the causes of the malfunction. The most important is to clearly identify the failure mechanism and propose effective improvements to prevent recurrence of the failure. After the failure analysis, we should find the real reason of failure and take measures to improve the reliability of the machine in terms of design, material selection, manufacturing, assembly, adjustment, use and maintenance. Failure Analysis is a multidisciplinary involving many technical fields, such as: system analysis, structural analysis, materials physics, test analysis, as well as related fatigue, fracture, wear, corrosion and knowledge of other disciplines.
This article will briefly introduce the analysis procedures and methods for the cause of the fault. Although the parts and components with the failure vary and the analysis methods and steps also vary, the basic procedures of the failure analysis are common.
The common procedures for the analysis of the failure of the machine are generally the followings.
First, collect background data and conditions of use. The main contents include the date and time of component failure, operating temperature and environment, the extent of the damage to components, the order of the occurence of component failure, the operation stage of the failure, abnormal or unusual sound of the fault parts, photographs or sketches for faulty components and their vicinities parts, any errors which may lead to the failures in the use, the skill level and view of the failure of the users
Second, we should know the focus of the camera for the fault-site. You should take pictures as soon as possible for the things that may be possible to quickly change. The things that may be possible to quickly change include equipment, the instrumented readings and the location of the control, those evidences which can be removed by the weather, pedestrians, vehicles or cleaning staffs, such as the traces on the ground, heated evidence, liquid and so on.
Third, we should know the main historical information of the failure pieces. The historical information Includes part names, marks, manufacturing number, manufacturers, using unit, the function of the components, the materials used, the relevant project, the using time until the failure, design drawings, manual, the guidance component production, manufacturing, testing and operating specifications. When a failure analysis has been done, we should conclude all the information, the survey records, testimony and test data that we have obtained. In this way, we can better improve our work.
