Fuel oil detecting device

Abstract

The invention discloses a fuel oil detecting device. The fuel oil detecting device comprises a pipeline, wherein a pressure sensor and a flow sensor are installed on the pipeline; the middle of the pipeline is a U-shaped section; two sides of the pipeline are a first horizontal section and a second horizontal section; the free end of the first horizontal section serves as an oil return pipe connecting end; a gas quick connector is arranged at the free end of the second horizontal section; probes of the pressure sensor and the flow sensor enter an oil path and are connected with a data acquisition processor, a data display and an alarm through conducting wires to form an operating circuit. The fuel oil detecting device realizes lubricating pipeline fault monitoring by monitoring the pressure and the flow value in the pipeline and performing simple operation processing, is relatively low in investment and maintenance cost, and has a high practical value.

Description

technical field [0001] The invention relates to a fuel oil detection device. Background technique [0002] The fuel return pipe and high-pressure oil inlet pipe of some vehicles are in the engine cylinder head, such as the Hino 30-ton dump truck. The engine type of this model is a water-cooled 4-stroke V-shaped 8-cylinder diesel engine. The working performance of the engine is gradually deteriorating. Due to structural problems, there are occasional failures of diesel oil entering the engine oil. After this failure occurs, the maintenance personnel need to open the cylinder heads on the left and right sides of the engine, and check the internal diesel oil return pipe and high-pressure oil inlet pipe. Check the interface to check whether there is any sign of oil leakage and diesel oil. There are 5 oil return pipe ports and 4 high-pressure oil inlet pipe ports on the left and right sides of the engine. The oil pressure is low, and it is difficult to observe with the naked eye...

[0002] The fuel return pipe and high-pressure oil inlet pipe of some vehicles are in the engine cylinder head, such as the Hino 30-ton dump truck. The engine type of this model is a water-cooled 4-stroke V-shaped 8-cylinder diesel engine. The working performance of the engine is gradually deteriorating. Due to structural problems, there are occasional failures of diesel oil entering the engine oil. After this failure occurs, the maintenance personnel need to open the cylinder heads on the left and right sides of the engine, and check the internal diesel oil return pipe and high-pressure oil inlet pipe. Check the interface to check whether there is any sign of oil leakage and diesel oil. There are 5 oil return pipe ports and 4 high-pressure oil inlet pipe ports on the left and right sides of the engine. The oil pressure is low, and it is difficult to observe with the naked eye whether there is diesel leaking out of the outlet port. If the engine speed is increased, oil splashes will occur, and the port cannot be observed; therefore, maintenance personnel often rely on their own experience to replace Replace the gasket at the interface of the oil return pipe or replace the high-pressure oil inlet pipe, and then put the engine oil to the standard position and then test the vehicle. Replace and test run again until the engine oil position is normal after the test run of the vehicle, then the fault can be resolved. In the process of solving this type of fault, the number of repeated repairs of the vehicle is relatively large. According to statistics: the number of repeated repairs can reach more than 3 times, so frequent The repairs increase the load of maintenance, and the blind replacement of spare parts causes the cost of spare parts to rise
