水环真空泵叶轮轮毂工艺改进

The Manufacturing Technique Reform for Hub of Impeller in Liquid-ring Vacuum Pump

2BE1系列水环真空泵叶轮轮毂按德国西门子公司工艺是采用铸造生产的,其铸钢轮毂质量不稳定,生产周期长。为改变这一状况,我们在消化、吸收引进技术的基础上,结合生产实际情况,采用焊接的方法制造轮毂,取得了质量好、成本低、生产周期短的效果。

The hub of impeller in 2BE1 series liquid-ring vacuum pump was manufactured by casting according to the technique of Siemens in Germany. Such a technique can easily lead to low stability in quality and long cycle in production. In order to change the situation, based on the digesting and absorbing the inport technology, combined with the production reality, we used the welding method to make the hub. Thus obtained the result of high quality, low cost and short productive cycle.
