With the development of science and technology, "intelligence" has indiscriminately penetrated into all aspects of modern life, and the seemingly cumbersome and extensive construction machinery has also embarked on the road of intelligence. As far as the construction machinery industry is concerned, “intelligence” is the application of modern communication and information technology, computer network technology, industry technology, intelligent control technology, etc. on engineering machinery equipment, so that products are more in work and production. Adopt intelligent methods to reduce the workload of personnel and improve work efficiency. After nearly a decade of development, China's construction machinery industry has achieved remarkable results. Now it has developed into the world's largest producer and seller, but the overall situation is still large but not strong. The intelligent level of product intelligence and production process is still relatively high. At a low level, facing the highly competitive construction machinery market, the road to intelligentization in China's construction machinery industry is imminent. SINOMACH (Luoyang) Construction Machinery Co., Ltd., which is known as the "cradle of China's compaction machinery", has been shouldering the mission of "leading the development of China's compaction machinery industry" for more than 100 years, and launched the first in China at the end of 2013. Intelligent double drum vibratory roller LDD312H-2.

5. Multi-function walking electric control handle simplifies the interactive operation of walking, starting and sprinkling.

6. Improve the uniformity of pavement compaction by adjusting and optimizing the position of the eccentric block in the steel wheel; the vibration unit damping fluid design reduces the impact of parts and reduces the compaction disturbance of the compacted material.

7. Ultra-high frequency vibration design, greatly improve the efficiency of compaction operation, high frequency up to 67Hz, 30% higher than traditional roller machine.

8. The combination of walking and vibrating mechanism is different to improve the bias drive design of the traditional model, like the rowing of the rowing boat, reducing the deflection tendency of the whole machine, ensuring the uniformity of the left and right driving of the whole machine, and the uniformity of the compacted material. Force. The front and rear wheel vibrations rotate in the opposite direction, and the single vibration applying direction of the vibrating wheel is improved at the same frequency, and the road surface compaction quality is improved by the simultaneous two-way equalizing force application.

Third, high reliability, easy maintenance

1. The key components adopt imported or market-proven mature technology products to ensure the reliable use of the whole machine. 2. It can realize traceability query of fault code and fault cause, accumulate and perfect database, facilitate the logical judgment of maintenance and repair of the whole machine, fully guarantee the timeliness maintenance of the whole machine and shorten the troubleshooting time.

3. Sprinkler system water pump, valve, water filter and other components can achieve ground maintenance.

4. Four-link patent structure, fully open hood, pump, valve, engine, three filters, oil, hydraulic oil, fuel oil, water, antifreeze and other maintenance at your fingertips.

5Vibration wheel is added with oil and gas pipe, reducer and oil release, easy maintenance.

6. The simple design of the double wire scraping board can realize the fixing of the scraping board at any position, which can reduce the unnecessary material wear of the scraping board, and the adjustment is convenient and reliable.

7. The drive disc shock absorber can be separately disassembled, the chute structure can be eliminated, and the bolt pre-tightening performance can be enhanced.

8. Maintenance time reminder appointment function, strengthen the pre-maintenance timeliness of the whole machine and improve product reliability.

9. The extensive use of imported joint hoses greatly improves the reliability of the whole machine.

10. The automatic power-off and automatic power-off of the shutdown are double-set, to prevent the unreasonable loss of the imported battery, and to extend the stop time of the whole machine. Fourth, the comfort is strong 1. Man-machine interface fault alarm and interactive operation, electronic control knob throttle, feel level control. 2. The operating table rotates 180 degrees to improve the blanking field of view. The soft-axis operation is simple and reliable. The color display can be adjusted according to the outdoor light inlet. 3. The cab is pleasing to the eye and the best sealed cab. While blocking the outdoor noise, the winter and summer use the configured air conditioning and mp3 music to reduce driver fatigue. 4. Excellent ventilation performance, rain-proof leakage design for overhead sunroof, humanized setting of tool box and cup holder, adjustable seat dimensions and adjustable steering wheel angle.

The construction machinery industry is a strategic industry that provides technical equipment for national infrastructure construction. It is also the most important sub-sector in the equipment manufacturing industry. It is one of the key areas encouraged by the state. The development of its manufacturing technology can fully drive the equipment manufacturing industry. Upgrades and technological advances are the concentrated expression of the country's comprehensive strength. At the same time, construction machinery faces the market economy and participates in global competition. Advanced manufacturing technology has become the core competitiveness of enterprises. It can be seen that intelligence will become the mainstream trend of the development of engineering machinery in the future.

Gas-Phase Ultrasonic Cleaning Machine

The principle of gas-phase cleaning machine is as follow. When the solvent is heated, the steam forms the gas phase zone. In this area, the oil on the surface of the workpiece is dissolved and washed by steam. When the steam condenses, the dirt along with the grease falls back into the tank to become the cleaning fluid. Then, the cleaning fluid is heated and gasified into steam to clean the workpiece. This continuous cycle ensures the workpiece is always surrounded by the steam of cleaning fluid which overcomes the problem of contaminated cleaning fluid in the past common cleaning process.

Trichloro ethylene, tetrachloro ethylene, dichloromethane,  isopropyl alcohol have very good cleaning effect with high stability, long usage period when they are used as metal cleaning agent. In Heat Exchanger factories, these degreasing agents are widely applied in cleaning fins, bars, parting plates, tanks and other Heat Exchanger Parts . After these heat exchanger parts with oil stain are soaked in the cleaning agent and cleaned by supersonic, they`ll be very clean which also ensure heat exchanger with good brazing quality.
