What are the classifications of rapid impact compactors? What are the advantages of rapid impact compactions?

In practice, it is found that the hydraulic system can be divided into different forms from different angles: the hydraulic system of the rapid impact compactor can be divided into an open system and a closed system according to the circulation mode of the oil.

1. The open system means that the hydraulic pump sucks oil from the oil tank, the oil drives the hydraulic actuator through various control valves, and then returns to the oil tank through the reversing valve. The structure of the system is relatively simple, and it can play the role of heat dissipation of the fuel tank and precipitation of impurities. However, because the oil is often in contact with the air, the air can easily penetrate into the system, resulting in unstable movement of the mechanism. The open system has a large oil tank and good self-priming of the oil pump.

2. In the closed system, the oil inlet pipe of the hydraulic pump of the rapid impact compactor is directly connected with the oil return pipe of the actuator, and the working fluid is closed and circulated in the system pipeline. Its structure is compact, the chance of contact with air is less, the air is not easy to penetrate into the system, and the transmission is stable.

3. By adjusting the variable mechanism of the pump or motor, the speed change and reversing of the working mechanism are realized, which avoids the hydraulic shock and energy loss during the reversing process of the open system.

4. The closed system is more complicated than the open system, because there is no oil tank, and the heat dissipation and filtering conditions of the oil are poor. To compensate for leaks in the system, a low flow oil pump and tank are usually required.

Advantages of rapid impact compaction

1. The transition is convenient, flexible and efficient, and the control performance is good. Installed on the excavator or loader of the equipment, the process of transition and construction is very flexible, and the operation is also very simple, which greatly improves the construction efficiency and reduces the construction cost.

2. Safety and environmental protection, eliminate noise. The hammer body of the rapid impact compactor is placed in the skin, which can greatly reduce the accidental injury to people, and at the same time play a very large role in eliminating noise, thus achieving the effects of safety and low noise.

3. The impact on adjacent structures is far less than other compaction methods. During the construction of the rapid impact compactor, the force propagation direction is mainly vertical downward, which has little impact on other adjacent structures. It can be constructed close to the bridge abutment, retaining wall and other structures, which is safe and reliable.

4. High speed and high efficiency, cost saving. The ramming frequency of HC rapid impact compactor is 30-80 times per minute, which significantly improves the work efficiency, and the ramming frequency occupies the front row in the same industry.

5. Wide range of uses, suitable for various fillers. The rapid impact compaction machine is not sensitive to the cost and moisture content of the filler, and has obvious compaction effect.

All in all, rapid impact compactors are of great significance in the construction of highways, railways, airports, ports and other fields at this stage. The classification and advantages of rapid impact compactors are also adapted to the development of the times and provide better road construction. s Choice.
