国兆科技-注塑机节能改造案例与经济效益

前言:与众不同的“压铸机、注塑机节电器”;1、专利技术 ; 2、不影响注塑生产周期、不影响生产质量;  3  、设备运行和各工艺稳定性好;4节电率高。节能减排响应国家号召。迎接新节能法颁布实施。
    本节能技术经过六年的使用注塑机运行考核,近几年在老客户推荐,逐步使注塑加工企业认同,确实塑件不减产量,产品质量合格率不降低,为客户节能降耗创造最大经济效益。如下是部分典型案例:
案例1:香港福田科技公司、2006年7月大陆深圳布吉丹竹头查氏电子实业(深圳)有限公司试用考核确认。8月份确定进行筹备第一期节能改造。查氏电子实业(深圳)有限公司(一厂)改造前供电负荷情况:大、小注塑机75台。4台800KVA变压器满负荷运行;每月4-5天自备发电机发电。9月份定单下发。第一期节能改造22台注塑机,改造电机功率550KW(其中有两台大型多台马达液压泵注塑机)。改造后节能效果显著,此项目在香港获得节能环保大奖。
    2007年7月份香港福田科技公司高层决定,查氏电子实业(深圳)有限公司进行第二注塑机节能改造。第二期改造33台注塑机。改造电机功率740KW(其中有25台变量泵注塑机)。2007年9月28日第二期节能改造工程竣工。节能效果第一期+第二期节省了一台800KVA变压器(火牛)电量,变压器已向供电局报停。
   变压器最佳经济运行90%负荷。800KVA变压器每年直接经济效益:1、变压器(年)基本费用,每KVA/24元,800×24×12=230400元人民币。2、变压器电量(年)计算:变压器平均按负荷60%计;每月26天计;800×60%×24×26×12=3594240kw/h(度)3594240×0.75(平均电价)=2695680.00元人民币
3、变压器无功功率未纳入计算,功率因数由0.85提高到0.98,但是供电局是考核用户重要经济指标。
  查氏电子实业(深圳)有限公司注塑机节能改造(年)节省:第一期+第二期;变压器基本费用+电量费用+力率(功率因数)230400+2695680+0(力率)=2926080.00元人民币
    节能效益结论:每年节电盈利292.6万
    节省下800KVA变压器扩大生产循环经济效益都是节能效果产生利润。
    社会效益:按国家能源部标准1kw/h(度)生产价值60.00元人民币计算。
    查氏电子实业(深圳)有限公司“注塑机节能改造项目”在香港政府获得节能环保大奖。现在查氏电子实业(深圳)有限公司不断挖掘一切节能潜力。福田科技高层开发第三期节能改造项目。
案例2:深圳市龙岗平山兴伟塑胶模具加工厂。地址:深圳市龙岗平山坪环工业区91栋。2002年至2005年前、后一共注塑机节能改造9台,电机功率185KW。节电率50%。其中02年安装的三台已运行5年零故障。节电器运行6000小时回收节电器投资。
案例3:深圳市龙岗上李朗工业区。柏城塑胶模具有限公司。2006年3月安装。一共3台注塑机,电机功率50KW。节电率60%。检查运行记录零故障。
案例4:深圳市松岗燕川北部工业园E1栋。博瑞特精密注塑有限公司2007年9月1期改造2台37KW,节电率平均37%。运行无故障记录。
案例5:深圳市西乡银田工业区新艺塑胶厂2003年4月改造一台37KW节电率57%。每小时节电10度。设备运行记录仪显示25000小时,无故障记录。
结束语
    “节能减排”是国家“十一、五”重点发展项目,也是考核各级官员政绩的硬性指标。
    注塑机、压铸机、中央空调、电解铜等被列为高耗能设备。新节能法出台后会有一些硬性管理手段,促进企业去挖掘节能创效、求发展。
其实节能最大得益就是企业的东家。案例1就是典型,他应用过多家节能企业产品。他不恐惧失败,最终找到节能技术定位。现在问老板您节能改造效益怎样?他回答:“节能改造后报停了一台800KVA变压器(火牛)”。节省多少钱?各企业老板算一算。
