Abstract : the basal work principle of electric welding mac hine are introduced . the application and safeguard of power electronics device ( e xample high - power scr and igbt ) are particular introduced 文摘:介绍了焊机电源的基本工作原理,并详细地叙述了电力电子器件(以大功率晶闸管、 igbt为例)在焊机电源中的应用和保护措施1 12 。
The middle big thorn and the hook body are forged together , nor the thorn of hook head and the hook , but it ' s not electric welded , either . maybe it ' s heat fusion . i think it may be like the steel inlaid or steel nipped fusion 中部的大刺是和钩体一体锻的.钩头的刺和钩不是一体的,但也不是电焊,可能是热熔合吧.想那工艺可能就像嵌钢/夹钢熔合差不多吧
Home trade ( except some regulation ) , it invests , manufacturers various cleaning machine , pump , valve , complete set water supply equipment , air compressor , electric welding machine , electric control cabinet , electric wires and other relative service 国内贸易(除专项规定) ,企业投资,生产制造各类清洗机、泵、阀、成套供水设备、空压机、电焊机、控制柜、电线电缆、以及相关产品的服务。
Yueqing guanghua electric co . , ltd is the quality net member unit of national electric welding machine and electron branch member unit of electricity association in china , it is the first group enterprise that has gain the production license of national mechanical industry 乐清市光华电子有限公司,系中国电焊机质量网成员单位,中国电器工业协会电力电子分会会员单位,是首批荣获国家机械工业部生产许可证企业。
Mica , vemiculite , quartz sand , colored grit , cobble , tourmaline , light calcium carbonate , feldspar , feldspar powder , marble , etc . 1 . the series of mica includes muscovite , golden mica , biotite , sericite , used in the fields of electric insulation , heat insulation , paint , plastic , rubber , electric welding , toiletry , etc . 精制石英砂粉,云母粉碎,轻质碳酸钙,重钙粉,蛭石块粉,以及长石粉,重晶石粉,硅线石,电气石,鹅卵石,等各种矿产品。
1 . 20m - 60m mica powder is mainly used in electric welding ; 2 . 60m - 325m is used in mica ceramics for its good performance in insulation , maintain uncarbonized under strong electric arc , long time performance in the heat of 350c . its heat expansion coefficient is adjustable as required 工业上主要利用它的绝缘性和耐热性,以及抗酸抗碱性抗压和剥分性,用作电气设备和电工器材的绝缘材料其次用于制造蒸汽锅炉冶炼炉的炉窗和机械上的零件。
The reinforcing - bar is coupled with the electric welded screw behind the face plate to make it become a strong whole , strengthening greatly the rigidity and strength of single aluminum plate curtain wall , guaranteeing the flatness and anti - wind and aseismatic ability in the employment for a long period 加强筋与板面后的电焊螺钉联接,使之成为一个牢固的整体,极大增强了铝单板幕墙的强度与刚性,保证了长期使用中的平整度及抗风抗震能力。
It not only can keep small change of blast volume and highly dust - collecting efficiency but also can allow to complete service and maintenance for replacement of cartridge without entering the inside of dust collector . the dust collector has been applied to plastic industry , metal treatment industry , electric welding industry , electronic industry , wood working industry , cement industry , etc . and has got favorable responses from the customers 滤管式集尘机系应用高压瞬间喷射原理而将粉尘震落可达到压损固定,风量变动小及保持高效率之集尘外,更换滤管时,工作人员可以不必进入集尘机内,即可完成维修及保养工作。
