一、前言在水流量标准装置组建的过程中,水源的压力稳定度是其装置的主要参数之一。如何研究和解决其装置稳压水源问题,将直接关系到整个水流量标准装置的系统精度、基建费用以及流量测试范围等。根据我厂在组建水流量标准装置过程中的一点经验,介绍一种稳压精度高、建造费用低、施工周期短、流量测试范围广,控制系统可靠、同时不受地理环境以及温度变化限制和影响的一种水流量标准装置稳压水源的设计方案。二、容积稳压法水源的提出在液体流动的过程中,若管道横截面积一
I. Introduction In the process of setting up a water flow standard device, the pressure stability of the water source is one of the main parameters of the device. How to study and solve the problem of water pressure of its devices will directly affect the system accuracy, infrastructure cost and flow test range of the entire water flow standard device. According to our factory in the process of setting water flow standard experience, introduced a high precision voltage and low construction costs, short construction period, a wide range of flow test, control system is reliable, without geographical restrictions and temperature changes and Influence of a water flow standard device design scheme of water supply. Second, the volume of water pressure regulator put forward In the process of liquid flow, if the pipe cross-sectional area of a
