Specific power consumption of machine tool equipment is reduced and produce can changeless

Union uses newest EC fan, achieve ideal ventilated result, circulate through first-rate air cooling, can make the specific power consumption of switch ark air conditioning is reduced about 45% up to now, still be opposite without a manufactory or user machine tool equipment after all bad news can the problem of how many has undertaken paying close attention to. Future, this kind of phenomenon will produce a change, when designing machine tool equipment can effect problem is being placed increasingly the schedule of engineers of research and development. According to professional personage estimation, the power consumption that installs use machine tool device in German home occupies the 10%~15% of total power consumption. Between enterprise of single type of production, 60% what the power consumption of equipment can take industry total power consumption even. Management of production of Darmstadt technology university, craft and machine tool institute (PTW) research result is very seductive: In the use phase of the machine tool, the specific power consumption of the machine tool can occupy his inside service life 20% of total cost. Up to now, when research and development and equipment of design machine tool, problem of specific power consumption attributes minorrer problem. The target of engineers of research and development is to should achieve very high treatment quality, speed, dependability and stability above all. Because the user is being purchased,this is when, do not have can effect problem mentions program of topic for discussion to go up. But this kind of circumstance had produced change now, engineers of research and development have energy-saving consciousness more and more, this also includes European Union committee to count machine tool equipment among them is high cost can the reason of the product, also include what what accept to other consumable the machine tool of purpose can in effect grade assess. This kind of practice has how many meaning and maneuverability after all, still have different opinion to this. But, people thinks consistently, there still is considerable energy-saving potential to be able to be dug on machine tool equipment. "Energy-saving model drive technology includes phyletic and various product, technology and plan, they can be used through intelligent means tie, according to the different specifications model of equipment, OK and economic be as high as total specific power consumption the sources of energy of 75% above. " the electric drive of company of Bosch Rexroth AG and chief of branch of sale of machine tool of control business department Mr Andreas Jenke say when speaking of energy-saving latent capacity. The problem of bad news report of equipment gets controlling on which link be after all you can raise a machine tool can effect? Actually, OK on a lot of link, because the total specific power consumption of equipment of a machine tool is comprised by the place of specific power consumption of a lot of single components on the machine tool,this is, be like advocate the actuating device of the electric machinery, feed drive electric machinery, system that change a knife, send makings device, refrigerant compressor, pump, hydraulic pressure device and compress component of ark of air, switch, refrigerant to purify conveyor, and aspiration and air conditioning. Accordingly, restraining equipment waste time to be able to be mixed carry high-energy effect respect, still very large energy-saving space can be used. "In the process of new product of research and development, can consider to reduce major variable factor continuously, have correct fixed position to the norms of equipment and dimension, often can achieve the goal that reduces specific power consumption and manufacturing cost from this. " the electric drive of company of Bosch Rexroth AG and chief of branch of sale of machine tool of control business department Mr Andreas Jenke say sturdily. When speaking of other energy-saving measure, he is listed went out to specific aim ground undertakes demand adjusts assisting drive (be aimed at hydraulic pressure system for example) and use efficient servo electric machinery and the intelligence that can feedback actuating device to wait for a problem. In ask about when be being put in the energy-saving latent capacity with how old move after all, mr Jenke says: "Taking this kind of different step (include plan of all automation technology) when, experience makes clear, the energy efficiency of the machine tool can be improved greatly most 45% , manufacturing cost can be reduced every year at most 10% . " he returns complement to say: "Energy-saving model drive technology includes phyletic and various product, technology and plan, they can be used through intelligent means tie, according to the different specifications model of equipment, can save the sources of energy of the 75% above that are as high as total specific power consumption. " project manager Dr. Sebastian Haupt of company of MAG Tech Center is in speak of equipment energy-saving when reserving, say: "Below the circumstance of two exercise, equipment should not close gate all night. " project manager Dr. Sebastian Haupt of the company of MAG Tech Center that is located in Switzerland thinks, energy-saving model photograph of principle of total cost of machine tool and company is united in wedlock, also will be a kind of very good sale basis. Use an unit according to different equipment, through adopting the equipment plan of energy-saving means, can dig a tremendous energy-saving potential. Below the circumstance of two exercise, equipment should not close gate all night. It is to should achieve fast tall moving loop to this condition, make equipment can achieve status of exercise be in order inside short time thereby. Equipment is in reserve also can divide when condition undertake for multistage, disconnect first for example pump group and electric machinery, disconnect again next control system. Cut bits to carry equipment to be able to move with certain time-interval. MAG company pays attention to energy-saving technology all the time in designing the job. Company of Ller Hille of MAG H ü exhibited machining center of the NBV400 that exhibits first on the meeting vertical to abandon hydraulic pressure element in EMO, and cutting tool uses dish bedspring to undertake getting stuck tightening, use pneumatic means to undertake loosening, its Eco mode can improve energy efficiency. This kind of mode is OK the energy-saving adjustment of basis place make choice of means, reduce speed and acceleration to a relatively appropriate numerical value, concern in order to make specific power consumption and crop reach first-rate proportion. Chief of department of research and development of switch ark air conditioning Dr. Joachim Maul that digs a companies of more Rittal RSC System Climatisation of energy-saving latent capacity thinks: "Measure what pass auto industry than be opposite, below same condition, specific power consumption dropped at most 45% . " chief of department of research and development of switch ark air conditioning Dr. Joachim Maul of company of Rittal RSC System Climati-sation thinks, still can dig a more energy-saving latent capacity on equipment, design a respect in switch ark for example. His illustrate: "Since since 2007, our user has used device of refrigeration of cold efficiency series, fetched very big gain. These cooling device basically are EC fan and newest pneumatics machine. But only these device are not enough, must flow to be installed into travel optimization to refrigeration loop zephyr, with great the bear of each component in reducing refrigeration to circulate and specific power consumption. Measure what pass auto industry than be opposite, below same condition, specific power consumption dropped at most 45% . " the generation product of these device already face city, the limits of the product still is expanding ceaselessly in. If can avoid to use refrigeration technology, that nature is a kind of best energy-saving measure. To this, need is heated up to significant loss beforehand and heating power condition undertakes the estimate with concrete suit is measured. When design and ark of the switch that make, should avoid quantity of heat of occurrence such as to embrace wait for a phenomenon. Example makes clear, the sources of energy is optimized model machine tool equipment is showing its structural frame stage by stage. German federal education and the associated project that study the ministry is aided financially should conduce to the further progress that drives this kind of machine tool. Management of production of Darmstadt technology university, craft and machine tool institute (PTW) at present 3 associated projects that aim to extract high-energy effect are spreading out: Be in " Energie MSP " in the project, the function to dynamoelectric main shaft piece undertake optimizing; Be in " Maxiem " in the project, will use the most efficient component on the market to produce the prototype that gives new-style machine tool, will conclude with this the energy-saving potential that gives to be able to be achieved at present; And be in the 3rd " E-Sim-Pro " in the project, will build a series of models and imitate system, so that be in,design phase can undertake to problem of specific power consumption most change.
