The invention belongs to the technical field of fuel oil supply systems, and in particular relates to a method, device and system for alarming fuel oil supply failures. The method for fuel oil supply failure alarm of the present invention comprises the following steps: obtaining the current temperature value of the fuel supply temperature and the current temperature value of the low-pressure oil chamber of the high-pressure oil pump; The difference between the current temperature value is greater than the set temperature difference, and the first alarm is controlled to alarm; according to the difference between the current temperature value of the oil supply temperature and the current temperature value of the low pressure oil chamber of the high pressure oil pump is less than the set temperature difference, control The second alarm alarm. In the fuel supply failure alarm method of the present invention, by controlling the first alarm to alarm, the problems of the fuel delivery pump, oil delivery pump pipeline, gasket or strainer can be determined, and by controlling the second alarm to alarm, it can be determined that the temperature of the fuel supply is too high. High problem, able to quickly determine the cause of the fault.
Description
technical field [0001] The invention belongs to the technical field of fuel oil supply systems, and in particular relates to a method, device and system for alarming fuel oil supply failures. Background technique [0002] During the operation of diesel engines, insufficient fuel supply often occurs. One is that the user often does not connect the fuel pump of the diesel engine for convenience, especially the marine engine user, who thinks that the fuel tank is high enough and directly connects the filter; the other is that the resistance of the primary fuel filter to dirt is too large, the fuel pump is damaged, and the fuel supply pipe is damaged. The passage is thin, the oil line gasket is damaged and the air intake, etc., cause the diesel engine to run out of fuel, which has a great impact on the performance and reliability of the diesel engine. The diesel engine cannot be loaded, black smoke will be emitted for a long time when it is loaded, and it will stop suddenly. It...
