Timely found the components and parts of crusher are worn having great significance to prevent the accident occurred in the process of operation. We can use the following method to inspect whether the components are worn or there are other defects: surface inspection, clearance dimension inspection, temperature measurement and so on.
1. Surface inspection:
(1) Whether the components and parts are missing or whether the position is right or not;
(2) Whether there is leakage at connection points of each component, like oil leakage. It shows that the components are worn or not correctly assembled, or there is no sealing gasket;
(3) Whether fixed strong enough, or lack of connection parts;
(4) Whether the machine are soiled.
2. Clearance inspection.
We can use feeler gauge to check. The normal clearance of articulation piece should be in the range of 0.01-0.5mm. The clearance between 0.05-0.1mm ensures the components shifting. For the small clearance, it needs force to move the components.
When the connecting parts are worn fast, the temperature of connecting parts is higher than the normal temperature that is the omen of fault. Due to the abnormal abrasion among components forming fierce sound, it shows that there are abrasion in machine parts that cannot check out from direct checking and trial test.
