一、概述对液体自动定量灌装,一般采用容积法和重量法。由于容积法受温度及气泡等因素影响致使计量误差增大。但鉴于容积灌装结构简单,灌装效率高,所以在油漆、食品行业采用较多,而重量灌装可以不受温度、气泡等因素影响,所以多用于称量精度要求高的场合。在我所研制的“气动油墨自动灌装机”上采用的自动称量系统,就是以重量法为基理, First, an overview of the automatic quantitative liquid filling, the volume method and the weight method is generally used. As the volumetric method by the temperature and bubbles and other factors, the measurement error increases. However, due to its simple structure and high filling efficiency, it is widely used in the paint and food industries. The weight filling is not affected by temperature, bubbles and other factors, so it is often used in places where the weighing precision is high. In my research, “pneumatic ink automatic filling machine” on the use of automatic weighing system, is based on the weight method,
