After the excavator is equipped with a breaker tool, it can be used for lightweight crushing and demolition operations, such as the crushing and repair of concrete pavement and cement pavement, but how to choose a suitable breaker is also a big question. The following briefly describes the optional breaker four key points:

01
excavator weight
A small excavator with a large breaker may cause the excavator to tip over. The efficiency of a large excavator with a small breaker is very low, and the breaker is easily damaged. Therefore, it is necessary to choose an excavator and a breaker that match the weight to maximize the performance. The working efficiency of the machine.

02
Working weight of breaker
The flow rate of the breaker determines the working frequency of the breaker, which in turn affects its striking force and working efficiency. When the output flow of the excavator is greater than the demand flow of the breaker, the hydraulic system will generate too much heat, and the components will be easily damaged if the temperature is too high, which will reduce the service life of the equipment; when the output flow of the excavator is less than the demand flow of the breaker, there is simply not enough heat. Power-driven hammer operation. Therefore, it is necessary to choose an excavator and a breaker that match the flow.

03
Breaker structure
At present, there are three common appearance structures of hydraulic breakers: triangle type, tower type and silent type.


Tower and triangle breakers
The above picture shows the tower type and triangle type breaker. The structure of both is to use two thick steel splints to protect both sides of the hammer body, but there is no protection for the front and rear sides. It is completely wrapped around, and the shell is made of vibration damping material, which can not only slow down the vibration of the hammer body, prevent the hammer body from loosening, but also reduce the noise, and the performance is relatively good.

04
Working conditions
Due to the high installation point of the tower type breaker and the excavator, and a large working range, it can play a greater advantage in horizontal and trench operations;

The installation point of the triangle breaker and the excavator is lower, it is easy to lift, and its impact frequency is faster, so the work efficiency is higher in concrete crushing and rock crushing operations.

Introduction to Excavator Hydraulic Breaker

Hydraulic breakers are referred to as "breakers" or "breakers". The power source of hydraulic breakers is the pressure provided by excavators, loaders or pump stations. work efficiency. The principle of choosing a hydraulic breaker is to choose the most suitable hydraulic breaker according to the model of the excavator and the operating environment. According to the analysis of Li Gong, a senior consultant of Hydraulic Talent Network, my country's hydraulic breaker is mainly imported from abroad. Well, Li Gong from Hydraulic Talent Network reminds everyone not to forget to support domestic technology so as to have better development.

Why is the work of the excavator broken hammer weak?

The breaker is one of the spare parts of the hydraulic excavator. It plays an important role in the project. If the breaker of the excavator is weak, it will affect the progress of the company to complete the project. How do we analyze and deal with the excavator? As for the problem of the power failure of the breaker, please follow the small card to read the following article carefully, and deal with the problem according to different situations.
