Abstract

The invention provides an engine test bed cooling water system. According to the engine test bed cooling water system, a test bed comprises a main gas path and a hot air switching and bypass device; the main gas path comprises a stable section, a gas inflow spray pipe, a test section and an exhaust system which are sequentially communicated through a pipeline in the gas flowing direction of the test bed; the hot air switching and bypass device and the test section are arranged in parallel. The engine test bed cooling water system comprises a cooling water input path, a water tank, a cooling water main supply path, a gas inflow spray pipe cooling path, a stable section pipe cooling path, an exhaust system cooling path and a hot air switching and bypass device cooling path. According to the engine test bed cooling water system, cooling of the stable section, the gas inflow spray pipe, the exhaust system and the bypass device can be effectively achieved, cooling water for low-temperature cooling is recycled, the test requirement is met, water resources are saved, and practicability and economical efficiency are well balanced.

Description

Technical field[0001]The present invention relates to the field of testing platform tests, and more particularly to an engine testing desk cooling water system.Background technique[0002]The cooling water system is an important supporting system for engine testing bench, which provides cooling water required by the corresponding parameters according to the needs of the test. For testing tables, there is often a need for a plurality of different models of engine machine tests, typically include water and large flow hydraulic dynamic power supplies with small flow, and they require different requirements for cooling water parameters. For example, when providing cooling water for the hydraulic dynamometer, the water pressure of the cooling water does not have a large fluctuation. When the cooling water system is operated, the liquid level of the cold pool and the hot tank is maintained within the design range, and it is cold The control of the water pump and hot water pump proposes a hi...
