Comprehensive engineering technology that maximizes its effectiveness. Shantui bulldozer maintenance technology will run through the entire life cycle of mechanical equipment demonstration, development, manufacturing, use, maintenance and retirement. It has a comprehensive, cutting-edge and practical flash point, and has become the commonality of mechanical equipment. Key basic technologies. Since the 1950s and 1960s, the nature and objective laws of maintenance have been thoroughly and extensively studied. Hitachi excavators were unable to work and were unable to repair and sell. The advanced Shantui bulldozer maintenance technology and maintenance practices in the middle of after-sales service have developed rapidly. This makes maintenance a logical series of tasks from passive to active. With the development of maintenance practice, that part of the theoretical innovation is based on the advancement of Shantui bulldozer maintenance technology as the basis for basic research or applied basic research results in science and technology fields to promote the development of Shantui bulldozer maintenance technology. Research on new lubricants and materials to control corrosion and antifouling coatings is based on surface chemistry and applied materials research.

Energy conservation and environmental protection have become one of the topics that people are most concerned about. The state also has explicit regulations to limit the emission standards of machinery and equipment, and all excavator manufacturers should adapt to this development trend. Tongda excavator manufacturers have introduced environmentally-friendly multifunctional wheeled excavators to meet the needs of consumers in the country to meet the needs of customers. Let me analyze the highlights of this multifunctional wheeled excavator. The variables of the main pump of Tongda 80 excavation model are synchronized with the movement of the main valve spool, which makes the hydraulic system better controlled and achieves the best working experience with fast and smooth movements. By optimizing the matching of the engine, the main pump and the main valve, the handling performance of the whole machine is greatly increased. Adopt working condition adaptive technology, the controller automatically matches the corresponding flow after collecting the signal, increasing power; using advanced energy-saving compact main valve, the pressure loss in the ring is reduced by 20%. Virtual repair, remote repair, interactive electronic technical manual and other technologies.

In addition, the traditional monitoring and diagnosis technology has been improved, new equipment and systems based on virtual equipment monitoring and diagnosis have occurred, and the intelligent development of the maintenance decision support system has been promoted. The ability to retrieve information from the system and the database has accelerated the integration of maintenance information systems and maintenance support systems. The development trend of multidisciplinary comprehensive crossover is obvious. Shantui bulldozer maintenance technology is a typical comprehensive engineering technology, and its development and innovation increasingly depend on multidisciplinary integration, penetration and crossover. All resource visualizations have been derived, not only the emerging research field of mountain bulldozer maintenance technology, many of which have crossed the traditional disciplines, sub-categories, full-life cycle development, and adaptability to the full life-cycle development of machinery and equipment. Maintenance technology and supportability of software products, etc. Research on comprehensive properties of equipment. Also. The Yuxi Komatsu excavator's after-sales telephone has been extended from the use phase to the full life cycle of the mechanical equipment.

Welding-dominant distributors such as boilers, bridges, heavy and construction machinery industries all over the world and domestic have been actively adopting international advanced welding processes and equipment. The use of advanced technology and equipment has improved welding quality, reduced welding costs and improved labor conditions for workers. At present, due to the fierce market, the production rate is increasing. The understanding of maintenance has broken through the traditional definition, and its concept has a long-term expansion: the long-term development of mechanical equipment maintenance ideas and strategies: from "post-service maintenance BM" to "preventive maintenance PM", "predictive maintenance PDM" and even "improvement" "Maintenance CM" and "Risk Maintenance" and other theories of "Concurrent Engineering" and deepened the theory of "Reliability-centric Maintenance". Based on the development of information, network and other technologies, developed countries have also proposed suitable for satisfying decentralized and New theories of maintenance support, such as "precise support" and "agile support", which are increasingly mobile. They are good at repairing excavators without movement.

High water temperature, no power, no power, no power, walking alone, card machine, hydraulic pump trembling, lack of power, no movement, slow motion, large hydraulic pump sounds, powerless, machine, car, high oil temperature, out of arm , Card issuance failure, etc. Individual factories in the construction machinery industry have begun experimenting with semi-automatic CO2 welding processes. With the continuous improvement of the quality of CO2 welding machines, especially the introduction of good-quality CO2 welding machines by several joint ventures, the quality of domestic welding wires and welding machine parts and accessories has generally risen, which has strongly promoted the development of CO2 welding machine technology. . The construction machinery industry should vigorously promote low-cost automatic welding. Although the highly efficient and energy-saving CO2 gas shielded welding process is not highly automated in the construction machinery industry, the construction machinery manufacturers should actively promote the technology of CO2 welding while adopting technology. Renovate continuous and perfect technology. The starter is used to drive the internal combustion engine to perform pre-rotation at a speed of 150 to 200 r / min without supplying power to the fuel system.

A certain amount of lubricating oil is transported and splashed on each lubricating surface, which meets the maximum requirements for lubrication oil between the various motion pairs, and achieves the purpose of reducing the friction damage between various parts at the time of starting, but this method has a large Large consumption. Take Cummins C series internal combustion engine as an example. The 24V battery is used to start. When the temperature is -18 ℃, the cold start current is 900A. When the temperature is 0 ℃, the cold start current is 640A. Therefore, a spare battery needs to be added. Shantui bulldozer repair and after-sales service technicians must use this method to strictly observe the start-up precautions before starting the fire. The fact is that it will make the combustion chamber temperature too low, rationalize the process, and reduce the chain cost. It is very important. Most developed countries in the world are clearly different from the traditional manual arc welding and advanced mountain bulldozer maintenance and service technicians and flexible welding system FWS after the sale, and use high-quality, efficient, energy-saving welding technology, and investment in welding equipment is not large.
