柱塞式计量缸在燃油涡轮流量计校准中的应用
Application of Plunger Typed Metering Cylinder to the Calibration of Fuel Turbine Flowmeter
摘要
Abstract
The flowmeter calibration device with double-plunger metering cylinder is presented.Through the system control and calculation,the metering flow of the cylinder and the measured value of the meter can be compared online,for meeting the demand of wide range and accurate calibration.Structure and design method of the device are analyzed and its performance is initially evaluated by simulation.Stroke and moving velocity of the metering plunger are experimentally studied for their influence on the meter factor,which suggests the preferable testing condition.Results show that this device can serve wider range calibration and has 0.2‰ stability of flow metering at most.关键词
