                Transducer is in of sugar-refinery mill transform program

                One, general situation
                In the refine sugar industry of our country, transducer already applied in fan, water pump to wait widely change torsion is laden, obtained remarkable energy-saving result. Mill regards sugar-refinery as principal manufacturing facilities, the control means that uses a convention all the time is decided fast move. Actually, from production craft is mixed energy-saving two respects will analyse, undertake technical reformation to mill not only effective and can mate improves enterprise beneficial result.
                2, manufacturing technology analysis
                Well-known, mill goes out leading is one of main factors that influence candy portion always receives. If mill goes out,lead rise 1% , call in always rate raise 0.88% ~ 0.92% . The factor that affects sucrose extraction basically has reason of the following respects:
                1. After fiber divides press press, sucrose leaves mediumly when extracting machine exit, expand again, the fiber that is compressed right now as oneself expand to be able to be sucked in exit already the one part cane juice of crush out, get at the same time the influence of machine efficiency, the candy share in sugar cane cannot be total crush out, this formed the candy share loss in bagasse.
                2. What sugar cane expects is broken degree reaching form is to make sure first are extracted machine the premise that take out. Sugar cane is broken had spent, cane juice easily extrude, the effect rises.
                3. Reducing bagasse moisture content is to rise those who take out assure.
                4. Assure to carry the ply of sugar cane layer that come over to be opposite equably from the machine that rip solution it is very important to raise sucrose extraction. If heavy panel of sugar cane layer, compress not complete, make bagasse creates waste; If sugar cane layer is too thin, press layer of not dry sugar cane, bagasse moisture is exorbitant, influence sucrose extraction.
                5. In the later period that extract season, wear away as a result of what extract roller more and more serious, bring about the clearance that extracts roller to expand, make sucrose extraction drops.
                The place on put together is narrated, because mill rotate speed is not adjustable, the time ply that carries the sugar cane layer that come over to have about 10% from the machine that rip solution is met short of requirement, such meetings make the average sucrose extraction of cane juice under 95.4% . Prediction of a person's luck in a given year of lower specification cane juice jumps over sucrose extraction big, bring about crop to become low thereby. If can undertake rotate speed adjustment to mill, spend after sugar cane layer insufficient when the reentry after making through reducing mill electromotor rotate speed sugar cane layer achieves normal ply compresses all right, such compressing the meeting is more sufficient, average sucrose extraction will can raise 0.2% above, reduce as a result of rotate speed at the same time, electric current drops to achieve the goal of energy-saving province report thereby. General passes transducer to solve the optimal device of this timing question just about.
