Problems solved by technology

The lubrication systems of modern diesel engines are basically the same, all of which are internal oil circuits. The test of the lubrication system can only connect sensors to measure the oil pressure at various places, but cannot determine the flow of oil at various places in the lubrication system of diesel engines, and lacks quantitative data on the flow of oil at various places.

Embodiment Construction

[0020] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments, but not as a basis for any limitation of the invention.

[0021] Refer to the attached figure 1 As shown, a diesel engine lubrication system testing device includes a test diesel engine body 1 and a test bench 5. The test bench adopts an eddy current dynamometer whose model is GWD250. The different positions of the test diesel engine body 1 on the oil circuit are respectively The installation hole is opened, and the transition joint 2 is fixed on the installation hole. The transition joint 2 is connected with the oil circuit in the test diesel engine body 1, and in order to ensure the tightness, a sealant is smeared between the transition joint 2 and the test diesel engine body 1 . The temperature and pressure sensors 3 for measuring the temperature and pressure of the oil are installed on the transition joint 2 one-to-one, and the temperature ...

Abstract

The invention relates to a diesel engine lubricating system testing device and testing method. The testing device comprises a diesel engine for testing and a testing rack, wherein a plurality of to-be-tested oil ducts of a diesel engine body for testing are correspondingly provided with installation holes, temperature and pressure sensors used for measuring the temperature and the pressure of lubricating oil communicate with the diesel engine body for the testing through the installation holes, the temperature and pressure sensors are connected with the installation holes in a one-to-one correspondence mode, and the two ends of a flow meter used for measuring the flow of the lubricating oil are connected with two installation holes in the to-be-tested oil ducts, so that the lubricating oilin the to-be-tested oil ducts flows back into the diesel engine body for the testing after passing through the flow meter, the temperature and pressure sensors and the flow meter are in signal connection with the test bench correspondingly so as to transmit data, the lubricating oil flow and the temperature and pressure distribution of the diesel engine at different positions and at different rotating speeds can be accurately measured in real time according to the device, so that quantitative research on a diesel engine lubricating system is facilitated.

Description

technical field [0001] The invention belongs to the diesel engine detection technology, in particular to a diesel engine lubrication system testing device and a testing method. Background technique [0002] Lubrication system is one of the indispensable systems of diesel engine, which directly affects the normal operation and service life of diesel engine. Diesel engines need continuous and sufficient oil lubrication during operation to reduce frictional resistance between transmission parts and wear of parts, reduce power consumption, and take away heat and impurities generated by friction. The lubrication system of modern diesel engines is basically the same, all of which are internal oil circuits. The test of the lubrication system can only connect the sensor to measure the oil pressure everywhere, but cannot determine the oil flow of the diesel engine lubrication system, and the quantitative data of the oil flow everywhere is lacking. When the oil volume is too much, th...
