Problems solved by technology

[0003] At present, the test equipment of the oil pump is in the form of a front-mounted oil pump, which has a loss of oil absorption height, and can only meet the test requirements of the oil pump installed outside the engine or installed inside the engine. For the oil pump installed upside down inside the engine, if the Existing formal test tooling for testing, the test conditions will have a large deviation from the actual application conditions, resulting in inaccurate test results

Abstract

The invention relates to the technical field of engine oil pumps, in particular to a test tool of an engine oil pump. The test tool comprises a test module and an engine support module. The test module comprises an oil outlet oil duct, a feedback oil duct, an oil outlet pressure detection piece used for measuring pressure of the oil outlet oil duct and a feedback pressure detection piece used formeasuring pressure of the feedback oil duct. The engine support module comprises a lubrication oil duct. A to-be-tested engine oil pump is installed on the lower surface of the test module in an inverted manner, an oil suction port of the engine oil pump communicates with an oil tank, an oil outlet of the engine oil pump communicates with an inlet of the oil outlet oil duct, an outlet of the oil outlet oil duct communicates with an inlet of the lubrication oil duct, an outlet of the lubrication oil duct communicates with an inlet of the feedback oil duct and the oil tank at the same time, andan outlet of the feedback oil duct communicates with a regulation port of the engine oil pump. The simulation test of the work condition of the inverted installation type engine oil pump in an enginecan be achieved, fitting of the tested work condition and the actual application work condition is good, the test requirement of the inverted installation type engine oil pump in the engine can be met, and it is ensured that the test result is accurate and valid.

Description

technical field [0001] The invention relates to the technical field of oil pumps, in particular to a testing tool for the oil pump. Background technique [0002] The function of the oil pump is to send the oil to the friction parts of the engine so that the oil circulates in the lubricating oil circuit of the engine bracket to ensure that the engine is well lubricated. The performance of the oil pump determines the lubrication effect of the engine lubrication system, so it is necessary to test the performance of the oil pump before use. [0003] At present, the test equipment of the oil pump is in the form of a front-mounted oil pump, which has a loss of oil absorption height, and can only meet the test requirements of the oil pump installed outside the engine or installed inside the engine. For the oil pump installed upside down inside the engine, if the Existing formal test tooling for testing, the test conditions will have a large deviation from the actual application co...
