  • 液压扳手在中国的发展历史
  • 本站编辑:杭州耐准精密机械有限公司发布日期:2019-11-25 22:19 浏览次数:

液压扳手全称应叫液压扭矩扳手,在国内使用不过50多年时间,最先在国内使用是德国的普拉多,随着德马克公司轧机设备进入中国,当时二重负责宝钢的辅机配套保工程,日本的扳手采用也随着轧钢设备进入宝钢,有好几套这样扳手,二重就把液压扳手研制交给当时的二重基础件厂来完成,由于当我国铝钛合金质量不行,就采用日本的全钢类型扳手,也就是现在我国的液压扳手标准和日本的差不多。 

铝钛合金扳手在我国使用,是美国的凯得克,当时改革开放,建设了大量电厂,也就是那时凯得克扳手随着大量进口发电机组进入国内,当时一套扳手要大几十万,当时的质量也是不稳定,到90年初,美国的实用动力把普拉多扳手引进中国以抗衡凯得克,也就是在这时杭州一家和马鞍山的一家应允而生,杭州那家一直发展不错,而马鞍山那家一直以国标为准,当时B扳手卖得不错,当时两家搭成协议,杭州的那家生产铝钛合金的扳手,以极低的价格供给马鞍山的那家,马鞍山的那家只生产全钢B型扳手,这时江苏泰州很多厂家都在模仿马鞍山的那家,叫大扭矩液压扳手,直到现在很多厂家产品宣传资料还是用的他们的图片。 

到2000年以后,液压扳手第一次得到大发展,上面两家基本能达到量产,到2005年以后,当时马鞍山的那家老总因患病去世,当时的业务员和代加工厂纷纷出来自己做,一个业务员到杭州成立公司 ,一个业务员到武汉成立公司,一个到黄山成立公司,南京有一家,马鞍山有四五家,杭州那家也有出的创办公司的,还有不知名的,也就在这以后,液压扳手才全面开花大发展,泰州的做的产品质量也有一定的提高,现在做的好的,大有后来者居上的趋势,例如南京黎旸液压机械有限公司,他们的液压扳手产品全部采用美国铝业的铝钛合金,液压拉伸器采用超高压150mpa,自动回位。 

液压扳手在的大发展和中国的经济也有一定关系,国内的基础建设大发展,重工业大发展,成就了液压扳手,国内的液压扳手进口(纯进口)仍占有一定的比例约25%,国内生产贴外国品牌(伪进口)的约25%,有可能更多,余下才是真正国产的,国产质量已经不比国外产品差,也就是伪进口卖得好的一个原因,由于纯进口和伪进口卖得价格比较高,给业务员的提成也高,给客户的业务费用也高,有足够的利润空间,售后服务做得比较好,这方面成就了纯进口和伪进口市场空间,这样纯国产的市场空间就有限了。

Full name shall be called the hydraulic wrench, hydraulic torque wrench is used in domestic more than 50 years of time, however, the first in the domestic use is Germany's prado, as the German mark company mill equipment into China, the double responsible for baosteel auxiliary supporting protection engineering, Japan wrench used as entering baosteel steel rolling equipment, several sets of this wrench, double the developed hydraulic wrench to double base parts plant to complete at the time, because when the quality of aluminum alloy, it USES the Japanese type of all steel spanner, which is now standard of hydraulic wrench in China and Japan.

Aluminum titanium alloy wrench used in our country, is in the United States grams, kay when reform and opening up, construction of power plant, which is then to kay wrench with a large number of imported generating set into the country, when a spanner to hundreds of thousands of big, the quality is not stable, by early 90, the United States the practical dynamic prado wrench into China to counterbalance kay grams, which is then a born by an answer and ma on shan, hangzhou hangzhou development that has been good, and ma on shan that have been subject to national standard, B wrench selling well at that time, the two take into agreement, the production of aluminum titanium wrench in hangzhou, At a very low price to supply ma 'anshan that, ma 'anshan that only the production of all steel B wrench, then jiangsu taizhou many manufacturers are imitating ma 'anshan that, called large torque hydraulic wrench, until now many manufacturers product publicity materials or use their pictures.

Hydraulic wrench to 2000 years later, get great development for the first time, the above two basic can achieve mass production, after 2005, ma on shan at the time the boss died because of illness, the salesman and co-packer out yourself, a salesman to hangzhou company, a salesman to wuhan company, a company established to huangshan mountain, nanjing one, ma on shan have four or five home, hangzhou that also has founded the company, there is unknown, also after this, the development of large hydraulic wrench to full bloom, Taizhou's product quality has also been improved, now do well, there is a trend of laters on the top, such as nanjing li Yang hydraulic machinery co., LTD., their hydraulic wrench products all use aluminum alloy, aluminum titanium alloy, hydraulic tensile using ultra-high pressure 150mpa, automatic return.

Hydraulic wrench in the great development of economy also have certain relations with China, the domestic infrastructure development, heavy industry development, achievements of the hydraulic spanner, the domestic import hydraulic wrench (pure entrance) still occupies certain proportion about 25%, domestic production put foreign brands (pseudo) imports about 25%, more likely, the rest is the true homebred, domestic quality is as good as foreign products, namely pseudo import sell well for one reason, because of the pure import and pseudo import selling price is higher, to the salesman commission is high also, to the customer's business cost is high, there are enough profits space, after-sales service to do better, This aspect achieved the pure import and pseudo import market space, so the pure domestic market space is limited
