As one of the most common parts of excavators, breaking hammers are now widely used in mines, railways, highways, municipalities and other workplaces. As we all know, the daily working environment of the breaker is bad and the working conditions are poor. Without a good breaker, it will not only not improve the work efficiency, but also cause malfunction. Therefore, choosing a good breaker is the key. Now Let’s share with you how to choose an good excavator breaker.
When choosing a breaker, there are generally several tips to consider:
1. The structure of hydraulic breaker:
There are currently 3 common appearance designs of hydraulic breaker, namely side-type hydraulic breaker, top-type hydraulic breaker,and box-type (silent) hydraulic breaker.
Side-type hydraulic breaker
top-type hydraulic breaker
Box-type hydraulic breaker
Application:
Based on rocks-breaking, breakers could be applied into any environment that requires, such as demolition, construction and deconstruction.
2. Comparison of 3 types hydraulic breaker:
Side-type and top-type usually use two thick steel splints to protect both sides of the hammer core. The price is relatively cost-effective. This structure design does not protect the front and back of the hydraulic breaker. Their disadvantages are It is noisier than the box-type hydraulic breaker of the same ton level, the steel plates on both sides are easy to loose or break, and the protection of the hammer body is not good. This kind of structure is rare in the European and American markets.
The structure of the box-type hydraulic breaker is that the shell completely wraps the hammer body, and the price is quite expensive. The shell is equipped with damping materials, which can buffer the hammer body and the shell while reducing the vibration of the carrier. The advantages of the box-type hydraulic breaker are that it can provide better protection to the hammer body, low noise, reduce the vibration of the carrier, and also solve the problem of loose shell, which is also the mainstream and development trend of the global market.
3. How to choose the breaker:
The weight and bucket capacity of the excavator, and full consideration of the weight of the excavator can prevent the excavator from tipping over due to the heavy weight of the breaker when the boom is fully extended. Small and can not give full play to the function of the excavator, and will accelerate the damage of the breaker at the same time. Only when the weight of the excavator and the breaker are matched can the functions of the excavator and the breaker be fully utilized. Under normal circumstances, the standard bucket capacity of an excavator reflects the weight of the machine. At present, a better method is to calculate the range of optional breakers based on the bucket capacity of the excavator.
The bucket capacity and the weight of the hydraulic hammer have the following relationship: Wh=(0.6-0.8)(W4+p)
When: Wh= WI+W2+W3W1—weight of hydraulic hammer body (bare hammer) W2—weight of drill rod W3—weight of hydraulic hammer frame W4—weight of excavator bucket p—density of sand, generally p=1600N /m3V an excavator bucket capacity.
RSBM can produce various types of hydraulic breakers and drill rods. Complete equipment, advanced technology, and processing and production in accordance with stricter corporate standards than the national standard. At the same time, in order to meet the needs of customers, different models and different qualities of drill rods can be processed according to the materials produced by different processes of different steel mills, thus breaking the disadvantage of the domestic market that high-end drill rods are completely dependent on imports and filling the domestic gap. Our products are cost-effective and the quality meets customer needs. And according to the differentiated needs of customers, we can develop drill rods that meet various working conditions.
The above is a brief introduction to the main types of breakers and precautions for selection. Users in need can refer to it. If you want to know more about the price, model, use and maintenance of the hammer drill rod, please contact us, thank you.
