Detailed Description
The utility model discloses a realize through following technical scheme.
As shown in fig. 1, a testing device for checking an air lock of a lubricating oil pump comprises a driving device, a lubricating oil pump 2, an oil supply level oil tank 3 and an oil return level oil tank 4, wherein the lubricating oil pump 2 is driven by the driving device, the driving device can adopt a motor 1 or a combination of the motor and a speed change gear box, the oil supply level and the oil return level of the lubricating oil pump are respectively connected with the oil supply level oil tank 3 and the oil return level oil tank 4 by using a pipeline 7, the pipeline 7 at an oil supply level inlet of the lubricating oil pump 2 uses a transparent hose capable of observing liquid flow, and the end part of the pipeline 7 can be controlled to be separated from or inserted into a lubricating oil medium of the oil. The oil supply level oil tank 3 ensures the height from the oil tank liquid level to the oil supply level inlet of the lubricating oil pump by using a structure capable of adjusting the height. A pipeline 7 at the outlet of the oil supply stage is provided with a valve 5 and a pressure gauge 6.
When the test is started, an inlet of a pipeline 7 at an inlet of an oil supply level of the lubricating oil pump 2 is inserted below the level of lubricating oil in an oil supply level oil tank 3, the lubricating oil pump 2 is driven to rotate to a specified rotating speed by using the motor 1, the pressure of an outlet of the oil supply level is adjusted to a specified pressure by using a valve 5 on the pipeline 7 at an outlet of the oil supply level, and the pressure of the outlet of the oil supply level of the lubricating oil pump 2 is recorded by using a pressure gauge 6; stopping the motor 1, adjusting the height of the oil supply level oil tank 3 to ensure that the height H from the liquid level to the oil supply level inlet of the lubricating oil pump 2 is up to a specified value (simulating the height from the liquid level of the engine oil tank to the oil supply level inlet), separating the end part of the pipeline 7 at the oil supply level inlet from the lubricating oil medium in the oil supply level oil tank 3, starting the motor 1 to drive the lubricating oil pump 2 to a specified rotating speed and stably operate, inserting the inlet of the pipeline 7 at the oil supply level inlet below the liquid level of the lubricating oil medium in the oil supply level oil tank 3, recording the time T when the lubricating oil medium flows from the oil supply level oil tank 3 to the oil supply level inlet of the lubricating oil pump 2, and judging whether the lubricating oil pump. And when the time T is greater than the specified time, judging that the air lock problem exists in the lubricating oil pump, otherwise, judging that the air lock problem does not exist in the lubricating oil pump.
The principle of the method is that the working state of the lubricating oil pump after the lubricating oil pump is installed on an engine is simulated through a ground rack device, particularly the height from the liquid level of an oil tank of the engine to an inlet of the lubricating oil pump is simulated, and whether the lubricating oil pump can supply oil within a specified time in the starting process of the engine after the lubricating oil pump is installed on the engine is judged by measuring oil suction time of the lubricating oil pump. The device for realizing the function has the advantages of simple structure principle, less parameters to be measured and easy operation. By using the device and the test method, whether the air lock phenomenon exists can be judged quickly and effectively before the lubricating oil pump is assembled to the engine, so that optimized remedial measures are taken in advance, the phenomenon that the engine works after being installed to the engine is influenced, and the starting failure fault is generated. The time cost and the economic cost generated by repeated disassembly and assembly of the engine can be effectively reduced.
