1 Current situation and problems in the lubrication industry
Lubrication is closely related to the operation of mechanical equipment. Efficient and reasonable lubrication technology is the basic measure to ensure and improve the energy-saving, high-efficiency, and long-term normal operation of mechanical equipment. It is the lifeline of mechanical operation and an applied science that serves the development of the national economy and people's lives. Therefore, the development and application of advanced lubrication technology and high-performance lubricants are the prerequisite for ensuring the energy-saving, high-efficiency, and normal operation of people's lives, work, and various industries' machinery. Therefore, developed industrial countries attach great importance to the research, development, and application promotion of advanced and reasonable lubrication technologies.
In the field of lubrication, it is divided into forms such as dry oil lubrication, thin oil lubrication, and self-lubricating. Among them, dry oil lubrication is the most widely used and also a powerful guarantee for the efficient and normal operation of existing mechanical equipment. Due to the non Newtonian nature of the lubricant being transported, the form of the lubricant tends to be between liquid and solid, making it extremely difficult to measure and pump. Therefore, the quantification, control, and detection of the dry oil lubrication system have always been a global challenge. Since the 1920s, dual line centralized lubrication systems have been invented abroad, and single line centralized lubrication systems were invented in the 1930s. After being introduced into China and achieving localized production, it has been used to this day, and various manufacturers have mainly produced and manufactured it. System research and development has also been limited to changes in appearance and installation methods, without any major breakthroughs.
The traditional dual line centralized lubrication system and single line centralized lubrication system adopt a fully mechanical structure in their structure and principle, so the system has insurmountable problems: when the system starts to supply, all lubrication points in the system supply oil at the same time. In order to ensure the lubrication of important bearings (short oil supply cycle, large oil demand), the oil supply cycle of the system is set to the required oil supply cycle of the bearing, which causes great waste of lubricating grease for other bearings and causes great pollution to the environment and equipment cooling water. The status of the oil supply process in the system is not visible, and it is difficult to check whether the oil is supplied. It is even more inappropriate to search for faults after they occur. Generally, it is only when poor bearing lubrication is discovered and scrapped that problems with the lubrication system are discovered, which causes great waste in production.
Beijing MCC Huarun Technology Development Co., Ltd. independently developed an intelligent lubrication system in 2000. This system breaks the traditional centralized lubrication system and adopts a new control mechanism and detection sensors to implement precise oil supply control and oil supply process status detection for each lubrication point. The system adopts a programmable logic controller (PLC) as the control center and sets up a field data bus (CAN BUS) to achieve real-time monitoring of the lubrication status of each lubricating bearing. The system is equipped with an upper computer monitoring system (HMI) to accurately display the lubrication status of any bearing on site in real-time. The oil supply process is intelligent, and in the event of a system failure, the system automatically takes corresponding measures to complete the oil supply. When serious errors cannot be self handled, a fault alarm is output and a fault code is transmitted to the upper monitoring system to identify the type and specific location of the fault. The on-site data bus of the system, in conjunction with various sensors on the bearings, collects relevant working information (vibration, shaft temperature) of important bearings on site, transmits it to the control center, and participates in lubrication control to achieve intelligent unmanned operation, greatly improving the safety operation coefficient of mechanical equipment and enhancing production efficiency.
At the same time, the system implements on-demand oil supply to each lubrication point, and the oil supply amount of any lubrication point in the system can be flexibly adjusted, so that the lubricating grease of each lubrication point can be distributed according to demand, and a small amount of multi meal oil replenishment method can be achieved, so that each point of lubricating grease is reasonably utilized, and the fuel saving effect is significant. Compared with traditional centralized lubrication systems, the fuel saving is 30% to 45%, and the average service life of bearings is extended by 50% to 150% year-on-year. The intelligent lubrication system is built on sensors and a decentralized control system(DCS)、 On the basis of fieldbus control system (FCS). With the development of sensor technology, it is constantly upgrading.
MCC CR Intelligent Lubrication is the first of its kind both domestically and internationally, and is in a leading position in the world. It has already applied for patents in countries such as the United States, Canada, the European Union, the Commonwealth of Independent States, Brazil, and India. Intelligent lubrication systems have been exported to Brazil, India, Türkiye, Mexico, the United Arab Emirates, Vietnam, Laos, Thailand and other countries. The company is actively exploring the American and European markets. The company has established a branch in the United States and plans to establish a research and development center in Europe.
2、 Analysis of Market Demand and Industrialization Prospects
At present, energy conservation and emission reduction tasks are heavy in various industries. Equipment and technology updates are being carried out in metallurgy, mining, non-ferrous and other fields. The use of intelligent centralized lubrication systems is of great significance in reducing equipment failures, saving lubricating oil, and protecting the environment. This is a critical period for the promotion of intelligent lubrication systems. The demand for intelligent lubrication systems is strong in industries such as metallurgy, mining, and non-ferrous metals, and products are in short supply. According to statistics, the annual market share of the lubrication industry in China is currently between 10-15 billion yuan.
With the continuous rise of oil prices, the price of lubricating grease has also skyrocketed. In the context of a sharp decline in profits for steel companies, it is urgent to save oil. In large critical equipment, traditional lubrication cannot meet the process requirements of equipment digitization and centralized control. The traditional single double line centralized lubrication system has shortcomings in its structure and principle, and cannot meet the requirements of modern factories. The key is that traditional lubrication systems cannot detect the oil supply status of each bearing, and it is even more difficult to determine the location of the fault point when a fault occurs. Causing the entire system to be in an uncontrollable state. This is the most headache inducing thing in device management. Equipment management personnel urgently need a lubrication system that can solve the above problems. The intelligent lubrication system has built its own on-site data bus, and the control terminal of the intelligent system is deep into the site, which can collect real-time data on the operation information of lubrication equipment and host equipment on site. Through the vast status database of the intelligent lubrication system, an equipment warning system can be established for the host equipment. The equipment warning information can be used in the oil supply control of the intelligent lubrication system, so the market demand space is very large.
The international market potential of intelligent lubrication is greater. The existing lubrication system is difficult to diagnose faults due to its inherent principle characteristics, resulting in high maintenance costs and higher labor maintenance costs; And intelligent lubrication can achieve unmanned operation, fault self handling, remote operation to judge the fault status, and accurately locate the fault location, greatly reducing the labor intensity of workers, improving labor efficiency, and improving the working environment of workers. This is more competitive in the context of high labor costs in developed countries in the Americas and Europe. In recent years, intelligent lubrication has strengthened its international promotion efforts and has participated in multiple exhibitions in countries such as the United States, Canada, Russia, and Mexico, with excellent results. It has also received inquiries from many companies around the world. In 2010, the exchange effect between China Steel and Taiwan was significant, and China Steel proposed a plan to promote it throughout the factory.
The intelligent lubrication system is now compatible with various heavy machinery. Newly built steel production lines, large-scale construction machinery, wind power generation, and many other fields. With the development and promotion of intelligent lubrication systems, they will inevitably lead and dominate the development of the dry oil lubrication industry.
The intelligent lubrication industry has just begun and belongs to the high-tech industry. Its market promotion is constrained by high costs, high investment in technology research and development, limited production and processing capabilities, and outdated traditional lubrication ideas. At present, the company is actively expanding its production scale, increasing market development and publicity efforts, and increasing research and development investment, in order to accelerate the pace of intelligent lubrication replacing traditional lubrication and rapidly promote the formation of the intelligent centralized lubrication industry.
