2 Development Objectives and Plans The US-imported Bingham Oil Pumps 9 and 10 of the Zoucheng Oil Transmission Station started from the second half of 2005 and experienced abnormal operating conditions. The continuous occurrence of end tile and waisted tile damage has resulted in the replacement of bearing bushes. 5 pay, in which the end tile 3 pay, the waist tile 2 pay, and the replacement cycle is getting shorter and shorter, the end tile and waist tile replacement 3 pay an average of 3 months, the service life is substantially shortened, resulting in greater economic losses, and serious Affects safety in production.

When we examined the disassembly of the 9-pump, we found that there was a steel pipe with a length of 50mm, 025mm, and a weight of 50g at the inlet of the impeller, and most of the peripheral blades of the impeller were severely deformed. To do this, it needs to be disassembled and replaced. However, the impeller and the pump shaft are closely matched for hot mounting. According to the instructions of the Bingham Company, the shaft with the impeller should be placed under the press with the impeller and shaft shoulder facing downwards. The bracket and the two wooden block support components are pressed vertically on the shaft with a press machine, and the impeller is evenly heated by the heating nozzle to exit the impeller.

As shown, we do not have the equipment required by the guide book. The time taken to send the equipment to this equipment manufacturer not only has a long period and affects production, but also has a very high cost of about 30,000 to 40,000 yuan, and there is a certain risk when it is dismantled. Therefore, we have considered the development of disassembly and assembly of impellers.

The goal of the development is to develop a safe, simple and practical impeller changer.

There are two target values ​​to be achieved: 1) to ensure that the impeller and the shaft are not subject to any damage; 2) to be simple, economical, practical, and to be able to use the same in future similar tasks. The cost is less than 10,000 yuan.

In order to shorten maintenance time and save costs, we decided to self-assemble and disassemble the impeller equipment. We carefully studied the Bingham company's work instructions and the structure of the impeller and the shaft. We think that as long as the impeller is clamped, the impeller is heated while the axis is With pressure, you can exit the impeller.

Three sets of solutions were developed for the development of special tools: Option One: counterfeiting tools in the guide book, making vertical tools; Option Two: To save costs, use jacks instead of presses to make vertical tools; Option Three: Use jacks instead of presses, Make a horizontal impeller assembly.

Implementation 1: Research instructions, measurement of machine dimensions According to Bingham's operating instructions, the parameters of the pump shaft and the impeller were carefully measured according to the specific impeller disassembly parameters.

According to the actual measurement of the shaft and the size of the impeller, we have drawn the machine manufacturing drawings.

Because the power used when disassembling the impeller is relatively large, all the implements must be sturdy. The 12-slot steel is used to make the main body of the machine. After testing, the top frames at both ends can withstand 10t pressure, which meets the requirements for strength and hardness when disassembling, in order to prevent the machine tools. Damage to the pump shaft and the impeller. Timber slots or copper plates are placed and installed on the pump shaft and the impeller in contact with the implement.

Place the pump shaft and impeller on the machine tool so that the impeller is in contact with the copper plate on the machine tool. Use the jack to hold the pump shaft. Apply a little pressure. Heat the nozzle evenly with the heating nozzle while keeping the pump shaft cool until the impeller temperature rises to 205. When the husband is left and right, the pressure on the shaft is gradually increased. The thermal expansion of the impeller relaxes the tightness between the impeller and the shaft, and the shaft smoothly exits under the action of the jack.

Through hard work, a simple, safe and easy-to-use impeller assembly and disassembly tool was successfully developed.

During disassembly, the shaft and impeller did not suffer any damage. Moreover, the construction cost is low (only 2500 yuan), the structure is simple, and the practicality is strong. In the similar work in the future, the aircraft has a promotion effect.

The technology is basically pollution-free. At the same time, far-infrared heating technology and vacuum heat treatment technology should also be vigorously promoted. They are all excellent energy-saving and environmentally-friendly green manufacturing technologies.

3 Main Approaches for Implementing Green Manufacturing Technology in China's Machinery Industry 3.1 Green Manufacturing of Green Products The green treatment of products has a positive meaning for the life cycle of the products. The green treatment is through various recycling channels, collecting useful resources to achieve sustainable use, and let The product cycle always presents a closed loop, which has a major effect on saving resources.

When the product is recycled after being scrapped, it naturally enters the next life cycle and is continuously recycled. The life cycle of the product will continue indefinitely. Therefore, designers should consider the structure and function of the new product in the design, for example, if disassembly is adopted. The design will be able to recycle the product again, and only the products designed for disassembly will have the opportunity to recycle the main parts and structures of the product and realize the recycling of the product. Only by incorporating the concept of product recycling in the design stage, the value of recycling will increase, so that the product can be efficiently recycled.

3.2 The use of green mechanical products 1) reduce the impact of mechanical impurities on the manufacturing process. The so-called mechanical impurities refers to dust, soil and other substances, impurities will fall into the mechanical fit between the surface, not only damage the matching surface, but also wear parts, damage the lubricant film. If the environment is in a harsh environment, use high-quality, supporting parts and components, and do a good job of impurity cleaning and prevention; 2) The temperature of the mechanical manufacturing is also a problem that affects the quality of the process. Parts will produce different temperatures during work, but also Different temperature ranges. Normal hydraulic fluid hydraulic oil temperature is between 30 弋 and 60 ,. If the temperature is lower or higher than this range, the degree of wear of the parts will increase, resulting in deterioration of the lubricating oil. Therefore, it is necessary to prevent machinery manufacturing from operating at low or high temperatures. 3) To ensure smooth manufacturing operations, it is necessary to ensure the stability of mechanical loads. The degree of wear of parts will increase with the increase of mechanical loads. Technicians should be careful not to exceed the maximum load that the machine can withstand, and to prevent problems such as part flaws during work.

3.3 Mechanical Product Packaging The green packaging of green mechanical products is similar to the above-mentioned green manufacturing. It realizes recycling and reuse within the product life cycle, realizes pollution-free production, allows products to be recycled or reused, and the packaging can also be large. The natural self-cleaning ability is automatically decomposed. The green packaging of products must not only pay attention to the beauty of packaging, but also prevent the packaging materials from being easily damaged. It also needs to consider the cost of packaging and the problems of easy decomposition and recycling to reduce the pollution to the environment.

The main types of packaging materials used in China are corrugated board, wood board, and plastics. Cardboard is most easily recycled, degraded, and less polluting. It is the best choice for packaging. However, the resources consumed in the manufacture of cardboard are large, and the damage to the environment is severe, and the strength is low, which easily leads to damage to the packaged goods. The strength of wood planks is large, and it is suitable for the packaging of large-scale products. However, wood is a non-renewable material, and excessive use will also lead to ecological imbalances. Plastic products are light in weight and have strong waterproof and windproof properties, but they are not easily degraded after use, causing serious environmental pollution. There is now a new type of green packaging (honeycombboard), which is currently one of the best packaging options for China's product exports. The promotion and application of honeycomb paperboard can reduce the breakage rate of product transportation and play a positive role in improving the quality of packaging products.

The new technologies and processes of the modern machinery manufacturing industry are constantly emerging. For example, ultrasonic cleaning technology, replacing the traditional gasoline and kerosene with water-based cleaning fluid, has a good cleaning effect and can prevent environmental pollution. Now it has been widely used in injectors, spinnerets, miniature bearings, instrument gears, and integrated circuits. The cleaning of microelectronic devices has a high degree of cleanliness of cleaning, and this aqueous cleaning solution can also be recycled. There is also a non-polluting electroplating solution, which can improve the serious pollution problems of traditional electroplating. The promotion and application of the brush plating process has improved the repair quality of parts, which not only saves costs but also reduces resource consumption.

3.5 Establish and Observe Environmental Protection System, Pay Attention to Green Awareness Education China's machinery manufacturing industry is gradually strengthening the establishment of ISO14001 environmental protection system, and strives to achieve integration with the ISO9001 quality system, providing a basis for various environmental assessments. The establishment of a sound environmental protection system allows manufacturing employees to recognize the various issues that arise during the entire product life cycle, and take effective measures to prevent and manage them, and to standardize environmental thinking and behavior. Machinery manufacturing enterprises must implement the idea of ​​balanced development of natural ecology, starting from the manufacturing process, and each link focuses on strengthening environmental protection forces. Pay attention to employees' awareness of safety awareness, quality awareness, awareness of saving, awareness of efficiency, and awareness of environmental protection. Raise all employees' correct understanding of economic, environmental, and social benefits and regard green production as a social responsibility for implementation and implementation.

To realize green design is to integrate the concept of environmental protection and pollution prevention measures into product design at the previous stage of product manufacturing, and realize the green development of product manufacturing. For example, we take the product's detachability, recyclability, and manufacturability as green. The basic concept of design ensures that the product is environmentally friendly, versatile and sustainable. Achieving green design requires that the product be manufactured with green raw materials and green manufacturing processes to achieve the lowest consumption of product manufacturing, prevent and reduce side effects in the production process, and when the product is scrapped, it should also be removable. Recycled.

4.2 Use of low-cost green manufacturing technology China's manufacturing industry has been using a large number of non-renewable metal materials as raw materials. This will not only affect the balance of the ecological environment, but also a great waste of national resources. In the machinery industry, manufacturing companies should actively promote sustainable use of green materials, optimize manufacturing processes, use green processes, and use modern advanced technologies to achieve the application of green technologies. Although green design and green technology are the key points for the development of the modern machinery industry, good materials are the basis for the promotion of the two. Therefore, manufacturing companies should improve the materials manufactured by the products and realize the sustainable use of the materials.

4.3 Green process technology combined with advanced production mode The advanced production mode is the driving force for the development of green technology. To achieve the transformation of manufacturing and production modes and the implementation of the reform of production mode, lean production, agile manufacturing, and intelligent manufacturing should be implemented. The combination of green technology and advanced production models, the strengthening of management, implementation of responsibilities, and implementation of green production concepts in green technologies can greatly reduce industrial pollution and energy consumption in the manufacturing industry.

Protecting the environment and maintaining the ecological balance are the hearts and minds of the people around the world. As the leading factor in social production, the machinery industry has been imperative to implement green technologies. China's current green technology manufacturing is still in its infancy and has not been completely universalized. Only through continuous optimization and improvement of modern technology, new technology and new materials, and strengthening management, we will start to save resources and reduce energy consumption, and actively implement green technologies. The promotion and application of green manufacturing technology will become the dominant process technology of the future machinery manufacturing industry and truly realize green manufacturing.
