The Manufacturer Of Jaw Crusher Introduces Common Faults And Solutions For You

Last Update:2020-05-05 06:21:04

It is learned from the manufacturer of the jaw crusher that if the jaw crusher bears a large moment or vibration during operation, it will often cause transmission system failure. The common ones are: the wear of the shaft head and hub caused by the clearance between the pulley and the shaft head, the wear of the bearing position caused by the eccentric shaft stress, etc. After this kind of failure, the traditional maintenance method is to enlarge the hub hole, repair welding or brush plating after machining repair. There are some disadvantages in these two methods: the thermal stress produced by high temperature of repair welding can not be completely eliminated, which is easy to cause material damage, resulting in bending or fracture of parts; while brush plating is limited by coating thickness, which is easy to peel off. These two methods are metal repair metal, can not change the "hard to hard" fit relationship, in the comprehensive effect of various forces, will still cause re wear.

The above two maintenance methods are not commonly used in western countries. At present, many developed countries in Europe and America use polymer composite repair methods to solve the above problems. The technology has super adhesion, excellent compressive strength and other comprehensive properties, which can be repaired on site without disassembly and machining. The use of polymer materials for maintenance has no effect of repair welding thermal stress, and the repair thickness is not limited. At the same time, the metal materials of the products do not have the concession, which can absorb the impact vibration of the equipment and avoid the possibility of re wearing. This maintenance method can greatly extend the service life of equipment components, save a lot of downtime for enterprises, and create huge economic value.
