Water supply system for hot commissioning of engine and water supply method

Abstract

The invention relates to a water supply system for hot commissioning of an engine and a water supply method. The water supply system comprises a large water tank, a plurality of hot commissioning racks and a plurality of engine water circulation systems, wherein the hot commissioning racks comprise stands and small water tanks; the large water tank is communicated with the small water tanks to form a large water tank water supply system; the small water tanks are communicated with the corresponding engine water circulation systems to form small water tank water supply systems; the large watertank is provided with a large water tank water supply port; the small water tanks are provided with small water tank water supply ports and small water tank water return ports; the engine water circulation systems comprise engine water inlets, engine water outlets, hot air inlets and hot air outlets; water supplementation pipes are arranged at small water tank water supplementation ports; the small water tank water supplementation pipes are communicated with the large water tank water supply port; the engine water inlets and the hot air inlets are communicated with the small water tank water supply ports; the engine water outlets and the hot air inlets are communicated with the small water tank water return ports. The water supply system can avoid the influence of ultrahigh water temperature on a hot commissioning progress.

Description

technical field [0001] The invention relates to engine heat test equipment, in particular to a water supply system and a water supply method for engine heat test. Background technique [0002] The so-called engine hot test is about to ignite the engine for testing. Simply put, it is to create a condition for the engine to be ignited on the bench, let the engine run, and then check the assembly quality of the engine through bench monitoring and manual inspection. [0003] Under normal circumstances, a hot test bench will be equipped with a small water tank to simulate the state of the engine on the vehicle to achieve the best state of the test. During the hot test, a large amount of heat will be generated when the engine is running. About 30% will be taken away by the cooling water. During the long-term hot test process, the water temperature will continue to rise until it affects the normal progress of the hot test process. Contents of the invention [0004] The purpose ...
