Problems solved by technology

However, the existing technology has limitations to a certain extent. In the case of blocking the port of the test piece, the test piece has only one inlet, which cannot form a liquid flow, so that the medium inside the test piece cannot be controlled at a specified temperature. The existing technology It is further proposed to directly heat the specimen during the test

Abstract

The invention provides a test device, and relates to the field of pressure pulse testing. The test device comprises: a pressure applying assembly, wherein thepressure applying assembly is communicated with an inlet through a first path, is communicated with an outlet through a second path, and is arranged to apply the same pressure to the inlet and the outlet at the same time; and a temperature adjusting member and a pumping member connected in series with the temperature adjusting member, wherein the two ends of the temperature adjusting member and the two ends of the pumping member which are connected in series are communicated with the inlet and the outlet respectively. According to the invention, the pressure applying assembly is adopted to apply the same pressure to the inlet and the outlet of the test piece such as the radiator at the same time, so that the radiator can bear the pressure pulse in the pressure pulse test, and the test can be carried out; and the inlet and the outlet of the test piece are communicated with the outside, and the medium in the test piece is circulated and heated by utilizing the temperature adjusting member and the pumping member, so that the temperature of the medium in the test piece can be stably controlled, and the temperature of the medium in the test piece can reach or be particularly close to the temperature of the medium in the test piece under the actual working condition.

Description

technical field [0001] The present application relates to the field of pressure pulse test, in particular to a test device. Background technique [0002] Components through which a medium flows, for example such components can be components in a hydraulic system, components in a lubrication system or components in a cooling system. Take the hydraulic system, lubrication system or cooling system as an example, no matter which system it is, each component included in the system will inevitably bear a certain pressure from the medium it circulates during operation, and as the equipment where the system is located When the operating conditions change, the pressure on the components will also change. In order to ensure that the design indicators of such components can meet the actual use requirements, it is usually an indispensable technical indicator to verify whether the product is qualified or not by using the pressure pulse to ensure that it can pass the pressure pulse test....
