Temperature, angle, flow rate and time controllable erosion test device and method

Abstract

The invention discloses a temperature, angle, flow velocity and time controllable erosion test device and method. The outlet of the reagent bottle is connected to the first inlet of the buffer bottle through the dosing pump and the check valve in turn. The outlet of the buffer bottle is connected to the first inlet of the two-phase valve through the centrifugal pump in turn. The second inlet of the two-phase valve is connected to the outside atmosphere. A hydraulic pressure sensor and a flow rate sensor are connected to the inlet of the erosion device. The angle controller is connected and installed on the erosion device. A temperature sensor is fixed on the inner wall of the erosion device. Connection, the first outlet of the diversion valve is connected to the inlet of the reagent bottle through the diversion pump, and the second outlet flows back to the second inlet of the buffer bottle through the pipeline; the reagent bottle, dosing pump, check valve and buffer bottle are all placed in the thermostatic bottle, and the constant temperature There is a heater inside the bottle. The invention can automatically adjust the erosion temperature, angle, flow rate and time, reduce labor costs, simplify the operation process, and recycle reagents at the same time, saving resources.

Description

technical field [0001] The invention relates to a test device and a test method, in particular to a temperature, angle, flow velocity and time controllable erosion test device and method. Background technique [0002] Pressure pipeline transportation has a wide range of applications and is widely used in petrochemical, coal chemical, biopharmaceutical and other process industries. Pressure pipelines usually have the characteristics of complex process, harsh operating conditions, and long operating cycle, and the conveying medium is often flammable, explosive, toxic, and harmful, especially the multiphase flow medium conveying system containing corrosive medium, involving multiphase Processes such as flow, cooling phase change, heat and mass transfer, etc., can easily lead to unplanned downtime accidents such as erosion and perforation of pressure pipes, leaking and bursting pipes in complex flow environments, and cause heavy losses. [0003] Erosion is the process of causin...

AI Technical Summary

Problems solved by technology

Aiming at the problems of pipeline damage and equipment damage caused by corrosive media erosion that are common in process industries, there are now a series of erosion and wear test devices, such as rotary erosion test devices, which have the advantages of small investment and floor space Small, the disadvantage is that there is a large deviation from the pipeline flow in real industry

The controllable factors of most erosion wear test devices are limited, and the erosion wear test cannot be carried out comprehensively. The degree of automation is low. At the same time, the corrosive medium cannot be recycled, and the waste of resources is serious.
