Construction Precautions for Large Breaker

　　large breakerIt is one of the accessories often used by excavators. It is often necessary to break apart in house demolition, mining, and urban planning and construction. If the operation method of the breaker is wrong, it will not only delay the construction progress, but also easily damage the breaker. Therefore, the reasonable application of the breaker has become a very important thing. Next, the editor will briefly introduce the precautions in the application process of the breaker. In actual operation, only by paying attention to these problems can we make more Secure application equipment.

1, vertical tap

Before the breaker is running, place the steel drill vertically on the broken object, and then turn on the breaker after confirming that the steel drill is stable. During the crushing operation, ensure that the steel drill is perpendicular to the knocked object at any time and anywhere; If the striking surface is skewed, the steel drill may slip, which will damage the steel drill and piston of the breaker.

2, it is strictly forbidden to play empty

When the large breaker is running, the steel drill should be close to the knocked object at any time. If the knocked object is broken, please stop knocking immediately. The body and the bolt rod will cause more serious damage.

3, can not be crushed in water

The breaker is not a closed structure, and usually cannot be immersed in water. It is very easy to damage the piston cylinder and damage the hydraulic oil circuit of the excavator. Therefore, try not to operate it in rainy days or in water; in special cases, except for steel drills , and other locations should not be immersed in water.

During the operation of the breaker, a very large kinetic energy will be transmitted to the rock layer. If the rock layer is broken immediately, the kinetic energy will be released. If the rock layer has a high hardness standard and is not broken after several blows, it will be converted into a very large thermal kinetic energy, so that the The temperature of the tip of the rod can reach above 400 degrees Celsius, which will cause the decarburization and softening of the drill rod, and then the surface layer will be coiled or even broken. Therefore, if the large breaking hammer cannot be broken for a long time, try to find another way to break.
