Erosion test device and method with capacity of controlling temperature, angle, flow velocity and time

Abstract

The invention discloses an erosion test device and method with capacity of controlling temperature, angle, flow velocity and time. An outlet of a reagent bottle is connected with a first inlet of a buffer bottle through a dosing pump and a check valve in sequence, an outlet of the buffer bottle is connected with a first inlet of a two-phase valve through a centrifugal pump, a second inlet of the two-phase valve is connected with outside atmosphere, an outlet of the two-phase valve is connected with an inlet of an erosion device through a first hydraulic sensor and a flow velocity sensor in sequence, an angle controller is connected and mounted on the erosion device, a temperature sensor is fixed on the inner side wall of the erosion device, an outlet of the erosion device is connected with an inlet of a diverter valve through a second hydraulic sensor, a first outlet of the diverter valve is connected with an inlet of the reagent bottle through a diversion pump, a fluid in a second outlet flows back to a second inlet of the buffer bottle; the reagent bottle, the dosing pump, the check valve and the buffer bottle are all placed in a constant-temperature bottle, and a heater is arranged in the constant-temperature bottle. With the adoption of the device and the method, erosion temperature, angle, flow velocity and time can be automatically regulated, labor cost is reduced, an operating process is simplified, reagents are recycled, and accordingly, resources are saved.

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.
