A test bench for internal corrosion of engine coolant cooling water tank

Abstract

The invention discloses an internal corrosion testbed for an engine coolant radiator tank. The internal corrosion testbed comprises a testbed mechanical device and an electric control gear, wherein the testbed mechanical device comprises a box structure comprising an upper experiment module and a lower control module, a water collector is arranged between the upper experiment module and the lower control module, a groove is arranged at the bottom of the water collector, the water collector is provided with a liquid level switch, a coolant circulation measuring and controlling device comprises a high level gas water tank which is arranged at the top of the box structure, the high level gas water tank is connected with the head end of a first pipeline, the tail end of the first pipeline is connected with a heating water tank, and the heating water tank is connected with the head end of a second pipeline through a bottom interface. According to the technical scheme of the invention, the flow, the pressure and the temperature of a simulated coolant are controlled, the corrosion condition of the interior of the radiator tank corroded by the coolant under the real condition is simulated to the greatest extent, and the precision of the test result is guaranteed.

Description

technical field [0001] The invention relates to a test bench, in particular to an internal corrosion test bench of an engine coolant cooling water tank. Background technique [0002] With the rapid development of the automobile industry and the demands of high-end customers, medium and high-end vehicles are favored and gradually become the protagonists in the market. People's pursuit of near-perfect vehicle performance requires continuous improvement in the production process of vehicles, and standardization and completeness of testing and testing equipment, so as to strengthen testing and testing of vehicles and improve vehicle performance. [0003] The automobile industry has more stringent domestic or international industry standards, some of which are mandatory, so it needs more complete testing methods to match them. my country's vehicle testing and testing equipment started relatively late, and some testing equipment still has gaps, especially The detection and testing...

AI Technical Summary

Problems solved by technology

The above-mentioned structure has the following defects. First, the degree of automation is not high, the dynamic monitoring and control capabilities of temperature, pressure, flow, and liquid level during the test process are limited, and the test accuracy is not high. Second, it can only be used for a single product. Corrosion test

Centrifugal water pumps for cooling water tanks with different displacements cannot fully meet the test requirements, and the test data cannot meet the technical requirements
