我国的螺杆泵介绍

我国的螺杆泵的初史阶段要从1984年天津从德国Allweiler公司的制造技术和英国Holroyd公司的2AC螺杆铣床和配套设备后算起。在那之前，法国工程师Moineau在1932年发明了单螺杆泵。算起来我国的螺杆泵要比国外整整落后了二十年。
在我国的螺杆泵中，其中生产_多的要数三螺杆泵产量，其产量达到了总产量的50%以上，位居__是单、双螺杆泵，而五螺杆泵的产量是其中_少的。据统计，我国螺杆泵的年产量总计大约一万多台。
对于螺杆泵的选材可以有很多选择，诸如：38CrMoAl、40Cr、20Cr13、16Mn、CrS5的、常需经渗氮硬化（HRc56-65）以及CrNi、CrMo、CrNiMo不锈钢、MnCrS钢等众多材料。在制造技术方面大多都是采用粗、精铣然后再到氮化。
China"s screw from the initial stages of the history of Tianjin in 1984 from Germany Allweiler the company"s manufacturing technology and the United Kingdom Holroyd"s 2AC screw milling machine and supporting equipment, the date after. Until then, the French engineers Moineau in 1932 invented the single-screw pump. Looking back, screw our country than abroad, a full two decades behind.
Screw pump in China, where the largest number of production output of the three screw pump, which reached a total output of more than 50%, ranking the second is the single, double screw, while the output of the five screw pump is one of the least. According to statistics, China"s total annual production of screw around more than ten thousand units.
The choice of material for the screw pump can have a lot of options, such as: 38CrMoAl, 40Cr, 20Cr13, 16Mn, CrS5, and often subject to nitriding, hardening (HRc56-65), as well as CrNi, CrMo, CrNiMo stainless steel, MnCrS steel and many other materials. In manufacturing technology, mostly coarse, fine milling and then to nitrogen.
