热处理设备选型误区

热处理设备选型误区 2011年12月03日 来源： 误区一：只看功率，不看频率在标准件、紧固件等透热时，当加热工件直径大于Φ60mm时，就应选择中频设备，此时仍用高频机则会造成工件外面“烧流”而里面“黑心”(俗称“烧不透”)，不仅设备效率大打折扣，还会降低模具寿命甚至造成模具损坏，无形中成本增高，却不知原因。误区二：只看输出，不看输入忽略了设备效率及耗电因素，等购回设备后才发现是“电老虎”，造成买得起，用不起的尴尬局面。例如同样是80机，但一个是输入功率80KVA，一个是输出功率80KW，但设备工作效率差别很大尽管也能完成加热要求，但耗电之大让用户叫苦不迭。输出80KW的设备输入功率竞高达120KVA。误区三：只看型，不看功率例如将设备单相输入电流120A~I输入功率120KVA混为一谈，统称120机，致使买回后才发现真正的功率才80KVA，明着占了便宜，实则暗里吃了亏。Mistaken idea one.onlvseeina the Power.does not see frequency.When standard comPonent,fastener,elc.are complelely hot,when heating the diameter of the work Piece and is greater thanΦ60mm,should choose intermediate frequency apparatus,can lead to the fact with high frequency machine Work Piece"cook,flow"butinside"evll mind"still at this moment (cornmonlv called as,"burn completely"),not only apparalus efficiency qive a areat discount,can reduce mould life-span even lead to the fact the mould to be damaged,the cost increases,but does not know the reason virtually.Mistaken idea two,only seeing and exporting,does not see input.Neglect apparatus effciency and power consumptive factor,just find it is"electric tiger"after buying the apparatus back,awkward situation causing affording,can't afford to use.For example likewise 80 machines,but one is input power 80KVA,one is output power 80KW,but apparatus working efficiency differs significantly,can even finish,heat,require,it is complained incessantly by users but power consumptive big．The input power of apparatus of outputting 80KW was up to 120KVA unexpectedly.Mistaken idea three,only seelng the type,not seeing the Power.For example import the apparatus single-phasely to electric current 120A and input power 120KVA to lump together,referred to as 120 machines,cause and buy back,just find real power just 80KVA,so bright as to qain extra advantage by unfair means,has suffered a loss secretly actually.(end)
