Large-scale breakers are a kind of accessories that are often used in excavators. They are often used in housing demolition compensation, mining, and urban planning and construction. If the operation steps are wrong, it will not only delay the progress of the project, but also make it easier to break the hammer. Therefore, the effective use of the hammer has become a very important thing. Now I will briefly introduce to you the common problems in the whole process of use. In the operation process, only by paying attention to this problem can It is possible to use machinery and equipment more safely and reliably.
1, vertical tap
Before operation, place the drill vertically on the broken object, make sure that the drill is stable, and then turn on the breaker. During the use of cracking, ensure that the drill is perpendicular to the object to be struck; if it is inclined to the beating surface, the drill will There is a possibility of slippage and damage to the drill bit and piston rod.
2, no air hits are allowed
During operation, the drill should be close to the vertical bisector being struck anytime and anywhere. If the vertical bisector is broken, please stop beating immediately. Empty hitting will cause the drill, flat pin, drill seat, front cylinder block, and bolt rod to be damaged. lead to more serious damage.
3, can not be used in water rupture
There is no closed structure, and it cannot be immersed in water at ordinary times, which is easy to damage the piston rod hydraulic cylinder and destroy the hydraulic oil circuit of the excavator. Therefore, try not to use it in rainy days and water; in special cases, except for the drill, other parts Cannot penetrate into water.
During the operation process of the breaker, a very large mechanical energy will be transmitted to the rock layer. If the rock layer is broken immediately, the mechanical energy will be released. If the rock layer hardness test method is relatively high, and the rock layer is still not broken after repeated blows, it will be converted into a very large amount of mechanical energy. The thermo-mechanical energy can make the temperature of the tip of the drill rod reach more than 400 degrees Celsius, which will cause the drill rod to be carburized and softened, so that the surface will have a curling knife or even a block. .
