Rapid Impact Compaction machine hydraulic system classification
In practice, it is found that hydraulic systems can be divided into different forms from different angles: the hydraulic system of Rapid Impact Compaction machines can be divided into open and closed systems according to the way the oil is circulated.
1. Open system refers to the hydraulic pump absorbing 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, which can play the role of heat dissipation and precipitation of impurities in the fuel tank. However, due to frequent contact with the oil with the air, the air easily penetrates into the system, resulting in unstable mechanism movement. The open system has a large oil tank and good self-priming of the oil pump.
2. In the closed system, the inlet pipe of the hydraulic pump of the Rapid Impact Compactor is directly connected to the return pipe of the actuator, and the working fluid is closed in the system pipeline. Its compact structure, less contact with the air, air is not easy to penetrate into the system, the transmission is stable.
3. The variable mechanism of the pump or motor is adjusted to achieve the variable speed and commutation of the working mechanism, which avoids the hydraulic impact and energy loss in the commutation process of the open system.
4. The closed system is more complicated than the open system, because there is no fuel tank, and the heat dissipation and filtration conditions of the oil are poor. To compensate for leaks in the system, a small flow pump and tank are usually required.
Advantages of high-speed hydraulic tamping machines
1. Convenient transition, flexible and efficient, good control performance. Installed on the excavator or loader of the equipment, the process of transfer and construction is very flexible, and the operation is very simple, which greatly improves the construction efficiency and reduces the construction cost.
2. Safe and environmentally friendly, eliminate noise. The hammer body of the Rapid Impact Compactor is placed in the skin, which can greatly reduce the accidental damage to people, and at the same time has a very large effect on eliminating noise, thus playing a safe, low-noise and other effects.
3. The impact on adjacent structures is much smaller than other compaction methods. In the construction of Rapid Impact Compaction machine, the direction of force propagation is mainly vertical downward, which has little impact on other adjacent structures, and can be close to the abutment, retaining wall and other structures for construction, 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 work efficiency, and the ramming frequency occupies a front-row position in the same industry.
5. Widely used and suitable for all kinds of fillers. The Rapid Impact Compactor is not sensitive to the cost of the filler and the moisture content, and has obvious compaction effect.
summary
All in all, Rapid Impact Compaction machine in the current stage of highway, railway, airport, port and other fields of construction, has a very important significance, Rapid Impact Compactor classification and advantages are also adapted to the development of the times, for the road construction to provide a better choice.
