径向扩压器叶间流道成形加工方法
摘要：
本发明提供了一种径向扩压器叶间流道成形加工方法，包括以下步骤：准备电解加工环境；在导流端开始进入通道内之后，使成形阴极以9mm/min～11mm/min的速度进给并采用直流电对通道进行电解加工；在喉道工作段开始进入通道内之后，使成形阴极以7mm/min～9mm/min的速度进给并采用直流电对通道进行电解加工；在扩压工作段开始加工叶间流道的扩压区域之后，使成形阴极以7mm/min～9mm/min的速度进给并采用脉冲电对通道进行电解加工；在导流端开始加工叶间流道的喉道区域之后，使成形阴极以1mm/min～3mm/min的速度进给并采用脉冲电对通道进行振动进给电解加工。
摘要（英）：

The invention provides an inter-blade runner forming machining method for a radial diffuser. The method includes the following steps that an electrolytic machining environment is prepared; after a flow guiding end begins to enter a channel, a forming cathode is supplied at the speed of 9-11 mm/min, and the channel is subjected to electrolytic machining by using direct current; after a throat working section begins to enter the channel, the forming cathode is supplied at the speed of 7-9 mm/min, and the channel is subjected to electrolytic machining by using direct current; after a diffusion working section starts to machine the diffusion region of an inter-blade runner, the forming cathode is supplied at the speed of 7-9 mm/min, and the channel is subjected to electrolytic machining by using pulse current; and after the flow guiding end begins to machine the throat region of the inter-blade runner, the forming cathode is supplied at the speed of 1-3 mm/min, and the channel is subjectedto vibration feeding electrolytic machining by using pulse current.
