DELIXI transducer notes the section report on model machine to transform program in Aokesi

40 thousand tons, platoon world the 4th. And the crop of Chinese synthetic resin still is in with 5% ～ the rate of 10% rises. China is plastic consumption big country, according to statistic, its year wastage takes the world the 2nd, be next to the United States, and consumption of average per capita is 19kg only, alive bound ranks the 32nd, the 11% ～ that are industrial developed country 20% , the plastic industry of visible China grows greatly even, plastic and mechanical perspective is wide. According to the market analysis of plastic products, at present production value of industry of Chinese plastic machinery makes an appointment with 10 billion yuan every year, and home market demand makes an appointment with 20 billion yuan, still have very large space, the demand of the machine that note model is progressively also by south northwardly diffuse, also head the development that will drive industry of plastic industry correlation at the same time. 2, frequency conversion is transformed go to plastic products in trend of development of the industry that note model for course of study, power consumption is the body that its produce cost, and one of equipment of main specific power consumption that the machine that note model is plastic products plant; As electric power electron and the development that frequency conversion controls a technology, undertake to motor of oil pump drive frequency conversion is controlled with will common mensurable pump instead the means of variable pump already was noting model wide application receives in the industry. Use frequency conversion energy-saving controller is right those who record model machine is energy-saving transform the cost of specific power consumption that already also made the industry that note model reduce the chance that note model, the most efficient way that enhances product competition ability. Because this popularizes communication,frequency control device is noting the application on model machine, to reducing the sources of energy waste has important sense. 3, the craft of the machine that note model is analysed 3.

Fundamental general situation reachs the 1 machine that note model shape process is common the machine that note model uses hydraulic transmission normally, its structure includes inject unit, open device combining a model, fluid drive device and electric control equipment, latter effect is the requirement that makes sure the machine that note model books working procedure (pressure, speed, temperature, time, position) work effectively with behavioral program. Device of the fluid drive in the machine noting model in the tradition basically controls electromagnetism of proportioning valve of electromagnetism of a powerful person, pressure, discharge by oil pump, hydraulic pressure electric machinery of oil cylinder, oil pump reachs the proportioning valve, action that all sorts of differring accessory of other hydraulic pressure and conduit composition, the motivation in fluid drive system drives oil pump to offer by electric machinery. Among them, oil pump majority is mensurable oil pump, electromotor offers rated power and rotate speed normally, the mechanical energy change that oil pump inputs electromotor place is pressure can, transport the hydraulic pressure oil that has constant pressure and flow to the hydraulic pressure component of hydraulic pressure system next, the requirement that load of drive of actuator of contented hydraulic pressure requires energy notes model machine to shape craft is according to booked periodic start course, namely in order to combine a model -- advancement ejaculation the mouth -- shoot glue -- protect pressure -- sol, cooling -- fly a model -- take out product -- the model that be noted in putting a pattern -- add up to a model to wait for treatment working procedure to achieve some product to shape. 3.

The main loss in the 2 common craft that note model the first for overflow loss. Differ along with product and treatment working procedure, place of each working procedure needs hydraulic pressure, discharge, pressure to differ, to oil pump motor, the load that the machine that note model is noting model procedure is to be in metabolic condition. And the discharge of pump is the largest flow that needs according to place will design, its note the hydraulic pressure flow that motor of model oil pump provides with constant rotate speed formerly, when the flow that needs when place of the machine that note model is less than the largest flow, redundant hydraulic pressure will pass circumfluence of overflow a powerful person, energy of this one part was dropped with respect to loss. The 2nd for reduce expenditure loss. The meeting when the mouth has the reduce expenditure that banishs classics a powerful person when hydraulic pressure oil to be pressed certainly fall, this is reduce expenditure loss. Because the reduce expenditure area ratio of directional a powerful person is older, so major reduce expenditure loss occurs on proportioning valve. Circulate for a long time amain as a result of hydraulic pressure at the same time flow and machinery of fluid casting die are acuteness grind, cause oil lukewarm exorbitant, noise is too big, the undesirable phenomenon such as mechanical loss of life. The 3rd to design surplus loss. In be being designed normally, general meeting considers common quality, when the design with most high capacity is a foundation, the capacity that designs because of electric machinery of this user oil pump compares real need tower above a lot of, exist " car of big Ma La " phenomenon, create a large number of waste of electric energy. The energy-saving principle of transducer of nextpage4, DELIXI and control system 4.

1 timing is energy-saving ask according to noting the craft of model machine, always approach a powerful person, low-pressure valve, press a powerful person, 2 switch that approach valve the frequency that the input end that after signal classics is changed, is added in transducer regards transducer as gives signal, transducer is handled through undertake real time sampling and passing CPU to its, the form of imitate signal thread that makes output frequency to follow proportioning valve changes, make in needing the process with pressure and lesser discharge electric machinery rotate speed is reduced, reduce the output power of electric machinery thereby, electric machinery can let stop into the process in refrigeration and semi-manufactured goods buy turn, make electric machinery reachs the smallest level in the energy loss inside whole and laden limits. 4.

2 raise power factor energy-saving without result power not only those who add line caustic and equipment is calorific, because,mainer is of power factor reduce those who bring about power of have rendered great service of electrified wire netting. By formulary S²=P²+Q² , φ of Q=S ＊ SIN, φ of P=S ＊ COS, among them: S- is inspected in power. Q- does not have result power, power of P- have rendered great service, COS φ - power factor. Knowable, jump over when COS φ big, p of power of have rendered great service is bigger. Common and mensurable pump notes φ of model machine COS to be worth in 0.

6-0.

8 between, and after device of use frequency control, as a result of the compensation action of capacitance of wave of the filter inside transducer, make COS φ ≈ 1, reduced thereby without work loss, increased the power of have rendered great service of electrified wire netting. 4.

3 soft start energy-saving because former electric machinery is,be started directly or Y/ △ is started, the electric current that start is equal to (3-7) times rated electric current, such meetings cause severe impact to Electromechanical equipment and power supply electrified wire netting, and still can raise requirement of capacity of electrified wire netting, the big electric current of the generation when starting and the service life that shake pair of equipment are very adverse. And use frequency conversion is energy-saving after device, the soft starting function that uses transducer will make start electric current from 0 begin, the electric current in the acceleration that maximum is installed in transducer by limitation is restricted a horizontal less than, do not exceed 1 commonly.

7 times rated electric current, reduced the concussion to electrified wire netting and the demand to capacity of electrified wire netting, prolonged the service life of equipment and mould. 5, DELIXI records model machine the characteristic of special transducer 1, rate of tall section report, section report effect assures to be in 30% ～ 70% . 2, the machine that note model is original control means and oil path are changeless, beardless original to recording model machine structure and control means are done fluctuant, need to be in only crude oil pump advocate place of electric machinery wiring strings together frequency conversion energy-saving controller, do to control line of scale of discharge, pressure receive switch appropriately and make simple shift try can finish. 3, use " town report ／ is energy-saving move " changeover controls fashion, withhold electric machinery of the lubricating oil pump that note model original Y - △ is started reach moving circuitry is changeless, ensure in case frequency conversion is energy-saving overhaul or controller malfunctions is to note model to add workpiece when cycle is too short still can switch arrives " town report " position job is produced with keeping normal. 4, move with synchronism of the machine that note model, debug finish cast after using need not any adjustment; Although change,mould and change machine parameter, all need not be opposite frequency conversion is energy-saving controller undertakes adjustment. 5, oil of model machine hydraulic pressure is noted to give out heat after transforming reduce apparently, compare commonly average oily Wen Jiang is low before transforming 15 ～ 20 ℃ above; Hydraulic pressure oily service life is attainable lengthen; Water consumption of refrigeration of the machine that note model can save 30 ％ above. 6, the protective function to whole system, (1) , the protection of transducer oneself; (2) , the protection to electric machinery; Be like: Short circuit of voltaic limitation, overload, output or output ground connection (3) , undertake protective to the damage that causes because of be being operated by accident; Be like: Did not arrive melt temperature forcibly the damage that sol causes rocket head, barrel, screw or sol motor. 7, noise of travel of the accident that note model is reduced apparently, , the vibration that lock up a model is reduced, prolong the service life of equipment and mould, improve working environment; Rise with electric power factor, oil pump advocate electric machinery is flowing start, when starting, be pounded without big electric current and can reduce distribution facilities size. 8, lengthen oil path the service life of sealed component, reduce shutdown maintenance odds, a large number of economic maintenance charge. 9, note model treatment is periodic (cooling time) longer, energy-saving effect is better; 6, be opposite since last word basis is long-term the pay a return visit of use manufacturer and observation, unanimous report uses frequency conversion to transform the following machine that note model not only saved electric energy for the client, and move reliable and smooth, protective function is strong, synchro control is accurate, the operation goes to the lavatory simply, satisfied requirement of Injection Molding craft adequately, stabilized product quality and crop. Reduce pressure oil at the same time oil is lukewarm, prolong the service life of sealed component, reduce equipment to uphold charge, created good economic benefits for the user, gained the satisfactory result of the user.
