在容积式流量计中,罗茨轮流量计,较其他形式的流量计(如:圆盘式、椭圆齿轮式,皮囊式等)有几个明显的优点:(1)体积小;(2)精度高;(3)能适用于各种不同化学性质,和不同粘度的流体;(4)基本上不产生金属磨损的粉末等等。由于上述优点,罗茨轮流量计的发展有着广阔的前途。而在罗茨轮流量计的生产中,首先需要解决的就是罗茨轮的加工问题。按照一般的做法,是把罗茨轮的齿廓曲线分为若干段来加工,因而工效低,精
In the volumetric flowmeter, the Roots flowmeter has several obvious advantages over other forms of flowmeter (such as disc, oval gear, bladder type, etc.): (1) Small size; (2) High precision; (3) can be applied to a variety of different chemical properties and different viscosity of the fluid; (4) basically does not produce metal wear powder and so on. Due to the above advantages, the development of Roots Rotameter has a bright future. In the production of Roots flowmeter, the first problem to be solved is the processing of the wheel. In accordance with the general practice is to Roots gear profile curve is divided into several sections to be processed, and thus inefficient, refined
