Scroll compressor was created at 1905, by a French engineering Leon Creux. But as the technology of the period was not advanced to construct a working product, first practical scroll compressors did not appear on the market until 1980s. Since 1970s, the energy crisis and the appear of high precision CNC milling machine brings the […]

Scroll compressor was created at the beginning of 1900s. Due to the limitation of processing technology, there are no product before the 1970s. Now the scroll compressor is the major compressor used by air conditioning. However, there are still many  technology shortages of oil-free scroll compressor. I find it hard to get the right equations for calculation […]

涡旋压缩机从20世纪初提出,此后由于加工技术的局限,一直到70年代才开始发展,而无油涡旋压缩机的技术出现更晚,由于其泄漏问题也限制了无油涡旋压缩机的发展。目前虽然涡旋压缩机已经占领了空调市场,无油涡旋压缩机技术仍然不够成熟,国内生产无油涡旋压缩机的厂家也不多。然而由于涡旋压缩机的众多优点,其发展的前景还是比较好的,不过目前对于涡旋压缩机的研究并不多见,这次做无油涡旋压缩机毕业设计就遇到了很多问题,设

涡旋压缩机最早诞生于1905年, 由法国工程师Leon Creux发明的,由于加工技术的局限性,80年代初才开始批量生产。70年代开始,由于能源危机的加剧和高精度数控铣床的出现,为涡旋机械的发展带来了机遇。

空气压缩机是一行业覆盖面非常广的通用设备,我国每年空气压缩机的总产量达500多亿人民币。而我国空压机行业生产水平一直处在较落后的水平,主要生产能力集中在传统的活塞式空压机,而近几年发展起来的螺杆式压缩机生产能力,也是以进口主机,整机国内组装的方式为主。

In electrical circuits, we use many resistances. You will see four or five ring printed on them. Despite of using multimeter, you have another choice to judge it. You can read the color of each ring and get the exact resistance.

在电子电路中经常使用到电阻,电阻有很多的种类和形式,在电子电路中,我们通常会使用到色环电阻,色环电阻的阻值就是根据不同颜色的环来确定其阻值的。那么怎么用色环来判断电阻的阻值呢?

I’m a student from China major at thermal energy and power engineering. After a hard time of looking for job, I finally get a ideal job. Here, I want to share my resume template to help students who are wonder how to create a great resume. You should always remember that a good resume do […]

2010校园招聘的大军已经过去有段时间了,后期的招聘会已经不多了。在大浪淘沙式的校园招聘求职过程中,张鹏还是选择到了比较好的企业,当然其实已经不是三一重工了,算起来还是比较的幸运吧,可以这么说。能够找到自己比较满意的工作除了我在五大技能提高应届生就业竞争力一文中提到过的几点外,一份好的简历也是不错的,下面也就吧我的简历也给大家看看,可以给同学做个热能与动力工程专业简历模板吧。
