I. Types of Quartering Hammers
There are many kinds of hydraulic quartering hammers. There are many sorting methods. According to the operation mode sorting, hydraulic quartering hammer is divided into two categories. They are hand-held one and airborne one.
According to the working principle, they are divided into three categories. They are full hydraulic type and nitrogen explosion type. There is also liquid-gas combination type. The liquid-gas combination relies on the expansion of hydraulic oil and rear compressed nitrogen. It works by together pushing the piston. At present, the vast majority of quartering hammer on the market belong to this kind of products.
According to the structure sorting of distribution valve, they are divided into internal valve type and external valve type.
In addition, there are various other sorting,
1. According to the feedback mode, they can be divided into two types. They are stroke feedback type quartering hammer and pressure feedback type quartering hammer;
2. According to the noise level, there are two types. They are low noise type and standard type.
3. According to the form of the shell, there are triangle and tower shape.
4. Accord to that structure of the shell, there are a splint type and a box frame type.
1. Mining: mountain cutting, mining, screen crushing and secondary crushing;
2. Metallurgy: slag cleaning, furnace dismantling and equipment foundation dismantling;
3. Railway: mountain cutting, tunnel excavation, road and bridge demolition, subgrade tamping;
4. Highways: Expressway repair, cement pavement breakage and foundation excavation;
5. Municipal gardens: concrete crushing, water, power and gas engineering construction, and old city reconstruction;
6. Buildings: Demolition of old buildings and crushing of reinforced concrete;
7. Ships: clam removal and rust removal on the hull;
8. Others: Ice breaking, frozen soil breaking and sand vibrating.
Ⅲ. Hydraulic quartering hammer model and type selection
1. Numbers on hydraulic hammer models may indicate excavator weight. It may indicate bucket capacity. It may also indicate the weight of the hydraulic hammer. It may indicate diameter of the drill rod, or the impact energy. In most cases, the number does not correspond to the meaning it represents. It is often a quantitative range. Sometimes the parameters of the hydraulic hammer have changed. But the model remains the same. This makes the meaning of model numbers more ambiguous. There are even data that do not match the actual data. Users should pay more attention.
2. The matching of hydraulic hammer and excavator is important. The main attention is the matching of weight and the matching of power for excavator users. For other load-bearing machinery, the matching of power and weight are important.
I hope you can have a broad knowledge of the working principle. You can learn basic structure and basic operation of the quartering hammer. I hope the above introduction can help you. It will play a positive guiding role in the actual construction.
