Constant-temperature and constant-pressure measuring device for flow of component

Abstract

The invention discloses a constant-temperature and constant-pressure measuring device for the flow of a component, and relates to the technical field of pipeline channel detection of components. The device comprises a heating liquid storage tank, a centrifugal pump, a pressure stabilizing tank and a flow inspection sealing device which are sequentially connected to form liquid phase circulation, wherein the heating liquid storage tank is used for storing a liquid phase and heating the liquid phase to enable the temperature of the liquid phase to be constant, and the centrifugal pump is used for pumping the liquid phase in the heating liquid storage tank into the pressure stabilizing tank; the pressure stabilizing tank is used for ensuring that the pressure of the liquid phase output to theflow checking and sealing device is stable; the flow inspection sealing device is used for placing a component to be measured, enabling the inlet and the outlet of the component to be respectively communicated with the heating liquid storage tank and the pressure stabilizing tank, and the flow inspection sealing device is provided with a flow meter I and a flow meter II at the inlet and the outlet respectively. The circulation loop with a constant-temperature and constant-pressure effect is established, so that the change of the passing flow is completely dependent on the component, and whether an irregular channel in the component meets the design requirements or not is judged.

Description

technical field [0001] The invention relates to the technical field of component pipeline channel detection, in particular to a component flow constant temperature and constant pressure measuring device. Background technique [0002] Flow refers to the amount of fluid flowing through the effective section of a closed pipe or open channel per unit time, also known as instantaneous flow. Nowadays, when it is necessary to measure whether the pipeline channel in the component meets the design requirements, most of them use the liquid flow rate per unit time to detect. Although the method is relatively simple, there are still some problems in practical application: [0003] Since there are many factors affecting the change of the flow rate, the flow rate, pressure and temperature cannot be effectively controlled, and the change affecting the flow rate cannot be completely determined by the components themselves, resulting in inaccurate measurement results. [0004] Based on this...
