China Railway Tunnel: remanufacturing the road ahead, a light
Since last year, in the "13th Five-Year" green development concept and "Chinese manufacturing strategic 2025" two countries under the influence of remanufacturing industry has been hitherto unknown attention.
However, users' doubts, low market recognition, lack of relevant standards and poor sales channels restrict the further development of remanufacturing industry. How to make the remanufacturing industry develop continuously and healthfully has become a new topic before the industry interface.
Relevant standards need to be set up
Although it has gone a long way on the remanufacturing of shield machine, how to get user approval is always the most realistic problem that China Railway Tunnel Group encountered when using remanufacturing shield machine.
"Shield machine is currently mainly used for urban rail transit construction. Most owners have very high requirements for shield machine condition from the perspective of security projects." China Railway Tunnel Group Special Equipment Center Deputy General Manager, chief engineer Meng Xianjun said, many owners will require the construction side using the new machine, use of time not to exceed a certain period of time does not exceed a certain mileage or driving equipment, let the owners accept the remanufacturing of shield machine is difficult.
Meng Xianjun said that at present, 4 remanufactured shield machines have been put into use in the China Railway Tunnel Group. "From the use of the situation, the construction effect is very good." But each time a new project is built, they are unavoidable to deal with the other's doubts about "remanufacturing products are not reliable".
And the problems facing the remanufacturing industry are far more than this one.
Remanufacturing is a new industry in China. The scale, economic benefits and energy saving and emission reduction functions of the industry need to be further developed.
One is that the classification of the industry is not clear. At present, the classification of remanufacturing areas is too scattered, which industries need to be remanufactured? At present, a complete system has not been formed at home.
The two is the lack of relevant standards. Taking shield machine as an example, there is no national remanufacturing enterprise approved by a country at present, and the state has not formulated corresponding remanufacturing standards. In fact, most of the domestic engineering machinery remanufacturing products lack the corresponding national standards, industry standards, not to mention local standards and enterprise standards.
The three is that the industrial chain needs to be formed. For large engineering machinery and Equipment Remanufacturing, electrical, mechanical, hydraulic and other systems need to be inspected and maintained. None of these works can be done independently. This requires the active cooperation of various systems to form a complete remanufacturing industry chain.
Pilot, pilot and try first
Recently, located in the center of China Railway Tunnel Group detection equipment on a Mangshan, the staff is detection of oil extracted from a shield machine in the.
"The oil of the shield machine is like the blood of the human body. It can be used to check the blood index of the human body to judge what a person may have, and the fluid is also the same." The staff introduced, for example, that the excessive copper content in the oil indicates that the bearing may be abnormally worn. They will detect the viscosity of the oil and other indicators to determine the working state of the whole shield machine.
The purpose of the test is to better evaluate the machine condition of the shield machine, which is also the starting point and important link of remanufacturing.
In order to develop industrial circular economy and promote industrial transformation and upgrading, China has launched the pilot demonstration of Electromechanical Product Remanufacturing since 2009. Two batch of remanufacturing pilot units have been identified, and China Railway Tunnel Group is one of them.
"The purpose of setting up a pilot unit is to pilot and try first, and we hope to keep the leading advantage in the remanufacturing field." At present, the China Railway Tunnel Group is preparing to build a remanufacturing base for the shield machine, Meng Xianjun said.
Meng Xianjun introduced that the National Key Laboratory of the China Railway Tunnel Group is taking the lead in formulating the remanufacturing standards for the enterprise shield machine. In the future, the base will provide supporting services such as remanufacturing equipment inspection, equipment supervision, training and other supporting services. It will become an integrated shield manufacturing remanufacturing base. It will open up external market on the basis of meeting the needs of shield manufacturing remanufacturing in the group.
The bright future looks forward to the departure
The attempt of the China Railway Tunnel Group is not a solitary example. For Luoyang LYC Bearing Co., Ltd., remanufacturing products from initial trial operation to today's steady mass orders, enterprises in the field of related development is essential. While they are planning to improve their production capacity this year, they are also actively seeking cooperation with other enterprises in order to form the related industrial chain at an early date. "It can be said that the remanufacturing industry is still in its infancy, which can be further developed." The person in charge of the enterprise said.
In the United States, the European Union and other developed countries and regions, remanufacturing industry has been developing for decades, and has formed a complete system in technology, processing and marketing. Compared with that, China's remanufacturing industry still has a large gap.
In May of last year, "made in China 2025" was officially released. It put forward the importance of sustainable development as a strong power in building manufacturing power, and strengthened energy saving and environmental protection technology, technology and equipment promotion and application, and promoted cleaner production in an all-round way. To build a green manufacturing system and take the road of ecological civilization. This will further clarify the status of remanufacturing from the national level. Under the new policy background, the related enterprises have a bright future.
Letter appoint relevant responsible person said that the industrial base of our city is abundant, only in the mechanical and electrical products, have the remanufacturing pilot unit of China Railway Tunnel Group, Luoyang Zhongche Locomotive Co. Ltd. both mechanical and electrical products, coupled with the relevant industrial system, I can say that the city remanufactured industry have a brilliant future.
Insiders suggested that the government and enterprises to jointly promote the development of remanufacturing industry: for the enterprise, to the drafting of their own production of remanufacturing product enterprise standards, and through the examination and approval procedures, rose to local standards and industry standards and national standards; for the government, according to the national overall planning requirements, and the manufacturing industry development roadmap, and by formulating relevant policies to encourage and actively promote the development of remanufacturing industry.
