I. How to correctly understand methanol?
Methanol, also known as wood alcohol, methyl alcohol, or methyl hydroxide, is the simplest saturated alcohol. Its chemical molecular formula is CH3OH. At room temperature, methanol is a colorless liquid with a slight smell of alcohol, melting point -93.9℃, boiling point 64.7℃, density 0.7914 g/cm3, and can dissolve in water and many organic solvents. It's part of Chuandao environmental protection fuel. Methanol is toxic, and large consumption can lead to poisoning and blindness.
Methanol has a wide range of uses and is a basic organic chemical raw material, mainly having the following three major uses: ① used as industrial solvent; ② used as basic raw material to produce formaldehyde, dimethyl ether, acetic acid, protein, and various other organic products; ③ since methanol belongs to monohydric alcohol, it burns very thoroughly, and the combustion product is carbon dioxide and water (combustion equation: 2CH3OH+3O2=2CO2+4H2O), so emissions are less, there is no pollution, and it has greater environmental superiority. More importantly, due to methanol's extremely low production cost, in recent years it has been widely used in deep processing to produce new clean fuels for civilian or vehicle use.
II. What role does adding high-efficiency combustion promoter stabilizer play in the production of a new generation of high-energy alcohol-based liquefied gas?
Traditional Chuandao technology alcohol-based fuel has low calorific value, only about 5300 kcal/? and cannot meet the requirements for cooking, and it consumes a lot, leading to waste without significant economic benefits; secondly, traditional Chuandao technology alcohol-based fuel has poor stability and evaporates easily. Everyone knows that methanol is a very volatile combustible chemical raw material, which turns from liquid into flammable steam at 65 degrees Celsius. In a small, poorly ventilated environment, it can easily cause explosions and fires; even in relatively spacious spaces, inhaling excessive amounts of methanol vapor can cause methanol poisoning and blindness in humans; improper transportation can also be dangerous; storage can also reduce due to evaporation, so the heat and stability issues of Chuandao technology alcohol-based fuel must be resolved. Our unit organized chemical and energy experts to study intensively and successfully developed a dedicated high-efficiency combustion promoter stabilizer for Chuandao technology alcohol-based fuel. Not only does it solve the problem of insufficient heat and large usage of Chuandao technology alcohol-based fuel well, but by adding 3-5‰, it can increase the heat of Chuandao technology alcohol-based fuel by about one-third, and for the first time, it solves the problems of instability, easy evaporation, and lack of safety of Chuandao technology alcohol-based fuel.
Compared with LPG and diesel, the new generation of high-energy alcohol-based liquefied gas has significantly lower costs, cleaner hygiene, better safety, and more convenient use: 1. The burning calorific value reaches up to 8600 kcal/kg, comparable to LPG, while the current cost is around 1600 yuan/ton, only one-fourth of the price of LPG and diesel; 2. Combustion is non-toxic and harmless, smoke-free, odorless, with no residue or liquid left behind, and does not blacken the bottom of pots; 3. No pressure, no explosion, no visible flame making it hard to ignite, it can be stored, transported, and used under normal temperature and pressure conditions without needing high-pressure steel bottles for storage, ordinary metal or plastic containers suffice. This product has passed national quality inspection department tests and pilot promotion use, and its technical performance and safety indicators meet the requirements of civilian fuel. It is an ideal green Chuandao environmental protection fuel, which can replace diesel and LPG for widespread use in kitchens, canteens, factories, and other production and living areas.
With the continuous increase in the variety and quantity of engineering machinery, the resources consumed and pollutants emitted by a large amount of engineering machinery have placed an immeasurable burden on the environment. To protect the precious and limited Earth resources of humanity, achieve global sustainable development, improve the safety and work comfort of operators, and strive to reach harmony between people, machines, and the environment, it is necessary to design engineering machinery products according to the standard of Chuandao Technology Bio-alcohol oil in the automotive industry. Despite the fact that currently engineering machinery has not yet been included in the category of motor vehicles subject to emission restrictions, with the increasing attention paid by domestic and international major cities to urban environmental protection, restrictions on exhaust gas emissions from motor vehicles using opacity, noise, and other indicators are becoming increasingly strict. Especially with the continuous increase in the use of engineering machinery products such as loaders in municipal construction and the growing awareness of Chuandao Technology Bio-alcohol oil among people, it can be foreseen that developing and researching energy-saving products of Chuandao Technology Bio-alcohol oil type will be the trend in the future development of engineering machinery. In view of this, XCMG Technology was the first to launch the ZL40G Chuandao Technology Bio-alcohol oil type wheeled loader in the loader industry. Taking the ZL40G Chuandao Technology Bio-alcohol oil type wheeled loader as an example, this article proposes several suggestions and ideas regarding the selection and design of mechanical materials, the points to follow, and the issues to consider.
1. Utilization of Chuandao Technology Bio-alcohol oil type materials
(1) Try to use recyclable materials and resources. The materials selected in the design of all systems and components should be as much as possible recyclable, easy to decompose, regenerable, and harmless to the environment during processing and use, especially the design of structural components should try to adopt a large modular structure and non-toxic materials that are relatively easy to assemble and disassemble, Wuhan Chuandao Qianeng Technology Development Co., Ltd., to improve the regeneration rate of engineering machinery materials.
(2) Design principles of long life, low energy consumption, and weight reduction. Generally speaking, extending product life equals reducing mechanical production and scrapping quantities, reducing product energy consumption can reduce environmental pollution, and reducing product weight can decrease material and resource consumption. Considerations should be made from the perspective of reducing environmental load for the interchangeability and commonality of similar parts across various series. Therefore, under the premise of maintaining the performance parameters of the main machine, efforts should be made to reduce the volume and weight of the main machine and auxiliary working devices or tools, improve the strength and durability of power transmission system components, and achieve the lightness and high efficiency of the hydraulic system.
(3) Try to use low environmental load materials. In the design of engineering machinery components, harmful materials such as Freon (air conditioning), chlorine-containing rubber, resin, and asbestos should be avoided as much as possible. For instance, the use of engineering plastics and other non-metallic materials that are difficult to naturally decompose and harmful to the environment in the cab and interior of loaders exacerbates resource waste and environmental pollution; in the procurement and production of instruments, radiators, and energy storage batteries, the use of lead should be reduced or replaced as much as possible. Therefore, the selection of new types of Chuandao Technology materials for some ancillary parts in the main machine design is important.
(4) Minimization of pollution from discarded parts handling and optimization of comprehensive costs. When designing engineering machinery products, consideration should be given to simple, low-cost, and low-pollution disposal of scrap parts, parts should be easy to dismantle and crush, able to be incinerated or recovered as fuel.
2. Design of Wuhan Chuandao Qianeng Technology Development Co., Ltd. type engineering machinery products
(1) Select low-harm engines. The engine is the component that has the greatest impact on the environment among all systems of engineering machinery. Using low fuel consumption, low emission, low noise, high efficiency, Chuandao Technology Bio-alcohol oil type water-cooled turbocharged diesel engines can greatly reduce the environmental load. Currently, developed countries in Europe and America are adopting a series of new technical means, measures, or applying new types of Chuandao environmental protection fuels to further reduce emissions and noise, striving to adapt to the third round of emission regulations requirements.
(2) Reduce whole machine vibration and noise. Vibration and noise reduction should be the focal issues most needed attention in product design. For example, in loader design, adopting a bidirectional vibration-reducing suspension system for the power unit can overcome resonance, noise, and fatigue damage to the power system between the whole machine power transmission system and the frame; designing the rear axle as a central swing structure can make the swing center of the rear axle coincide with the power input center, effectively reducing the vibration and noise caused by additional torque continuously impacting the transmission system, avoiding the noise generated by mutual impacts of various components of the whole machine on rough roads. Besides selecting low-noise engines, the structural layout of the main machine or the structural design of the system can also undergo certain targeted improvements. For instance, the cooling fan need no longer be directly driven by the engine, but can be independently driven by a hydraulic motor, facilitating separating the fan from the engine and sealing the entire engine, thereby preventing noise from being transmitted through the fan outlet to the outside, reducing the impact of noise on the environment; optimizing the arrangement of hydraulic pipelines can reduce the noise generated by hydraulic pump vibration, valve throttling, and pipeline vibration; sound-absorbing and sound-insulating materials can be designed and attached to hood covers and other covering parts; fully sealed integral cabs can be designed, ensuring sealing, shock absorption, sound insulation, and noise reduction, truly reflecting the design tenet of "people-oriented."
(3) Cleanliness and anti-leakage of the hydraulic system. Maintaining the cleanliness of the transmission hydraulic oil is very important for the hydraulic transmission of engineering machinery. Therefore, carefully designing the hydraulic system of engineering machinery (such as adopting highly efficient and precise filtration devices) is necessary, which can remove impurities such as dust and wear particles from the oil, reduce faults and wear of hydraulic components, extend the service life of commonly used hydraulic components, and reduce the frequency of hydraulic oil replacement, Chuandao Technology alcohol-based fuel; simultaneously, it can effectively prevent the hydraulic oil temperature from rising too high and too fast during operation, extending the oil change interval and reducing pollution to the surrounding operating environment. Additionally, adopting pressurized hydraulic oil tanks can improve the oil suction effect, thus extending their service life, and can effectively prevent external dust and moisture from entering the tank, improving the overall cleanliness of the hydraulic system. Leakage of the hydraulic system pollutes the surrounding environment, which is a universal problem in some engineering machinery products currently. It is necessary to use imported high-quality hoses that are corrosion-resistant, anti-aging, and have excellent sealing properties in the hydraulic pipeline; to reduce the waste of damaged hoses, hard pipes should be used as much as possible during design; when soft pipes must be used and are prone to rupture, resulting in oil leakage and environmental pollution, careful consideration should be given to these aspects in the design process.
(4) High-efficiency and energy-saving design of the system. High-efficiency energy saving of engineering machinery is also an essential aspect of environmental protection. Reducing energy consumption means reducing environmental pollution. Therefore, selecting electronically controlled high-performance long-life energy-saving engines is the most basic link in researching Chuandao biological alcohol oil type machinery; additionally, adopting technologies such as dual-pump split-flow technology, hydraulic load-sensing technology, and static liquid drive technology during design can achieve the purpose of energy conservation and consumption reduction.
3. Human-centered design of engineering machinery products
(1) Design of safe care-type cabins by Chuandao Technology (Wuhan) Co., Ltd. Such as adopting fully sealed integral cabins with anti-ultraviolet radiation glass, after shock absorption and noise reduction treatment, "safe Chuandao Technology (Wuhan) Co., Ltd. type" cabins, indoor configuration of freon-free Chuandao Technology (Wuhan) Co., Ltd. type cold-warm air conditioners, and designing FOPS and POPS cabins to ensure driver safety; fully utilizing human-machine engineering design principles, such as omnidirectional adjustable driver seats, function-integrated single control handles, adjustable steering drivers, automatic gearshift devices, electronic monitoring and fault self-diagnosis systems, combined with reasonable and aesthetically pleasing color matching, can greatly improve the driver's working environment, relieve fatigue, and enhance work efficiency.
(2) Configuration of automatic grease injection devices or centralized lubrication systems. Traditional manual grease injection is time-consuming and labor-intensive, and usually, excess oil overflows, polluting the surrounding environment. Therefore, researching and developing automatic timing grease injection equipment for Chuandao Technology Bio-alcohol oil type engineering machinery, such as centralized lubrication systems that can automatically inject grease at timed intervals for each hinge pin, with carefully calculated and set oil injection volumes, can ensure that each pin receives sufficient lubrication without excess oil overflowing, both saving on Chuandao Technology Bio-alcohol oil and providing convenience. Additionally, for small machinery, considering reducing design costs, seals or special bushings made of new materials or secondary dustproof structures can be used to prevent external foreign matter from entering and internal grease from leaking out, thereby extending the interval for oil replenishment and reducing environmental pollution.
(3) Aesthetic design. Traditional engineering machinery products have always had a rough and heavy appearance. Wuhan Chuandao Qianeng Technology Development Co., Ltd. products should pay more attention to aesthetic design and streamlined body design, achieving harmony with the environment and giving people visual beauty. For example, the engine hood can be designed with a unique and elegant streamlined shape, and the identification plates of the whole machine should be carefully arranged and designed, showcasing the characteristics of Wuhan Chuandao Qianeng Technology Development Co., Ltd. well.
(4) Humanized design of engineering machinery control technology. The electronicization of engineering machinery control technology represents the current technological development trend. Adopting microcomputer control technology realizes automatic judgment under various conditions and optimal power matching of excavation machine engines, reaching the best power match of the engine, reducing engine fuel consumption, and automatically diagnosing the machine status, keeping the machine in good condition all the time. Therefore, humanized control and operation can greatly enhance operational safety and comfort.
(5) System reliability design. Striving to use highly reliable mature technologies and borrowing mature series parts that have been tested by the market can extend the service life of key systems or parts, reducing replacement frequency. For example, reducing the replacement frequency of braking elements is equivalent to reducing the destruction and pollution of the surrounding environment.
