What about engine noise and flameout of three-way internal combustion scraper
With the continuous development of science and technology, in order to greatly reduce the expenditure of human, material and financial resources and reduce the secondary
waste of resources, the tripartite internal combustion scraper has the characteristics of stable loading, large control range, no spillage, high efficiency, continuity and so on,
and has been widely used. The tripartite internal combustion scraper is suitable for mines, railway tunnels, hydraulic culverts and other departments. Here's how to deal with
noise and flameout of the engine of the tripartite internal combustion scraper:
If the "AC charging indicator" or "engine oil pressure" signal is on when operating the scraper, the engine should be shut down immediately; If the "cylinder head temperature"
signal is on, stop the scraper and let the engine gradually cool down, allow the engine to idle for a few minutes, and then stop.
Turn off the main power switch. If the outdoor temperature is lower than -300C, remove the battery and move it indoors to avoid freezing and cracking.
When there is no emergency, the engine is not allowed to stop suddenly from full load, should first let the engine cool down, and then stop the three-way internal combustion
scraper; Press the "flame out button" and press the "Stop button".
The noise on the tripartite internal combustion scraper can be divided into three categories according to its production mechanism, that is, air dynamic noise, combustion noise
and mechanical noise, and the air dynamic noise in the exhaust system is usually the main noise source, in general, if the exhaust noise of the diesel engine can be effectively
reduced, the total noise level of the scraper can be greatly reduced. Under normal conditions, the noise of the scraper rises linearly with the increase of its speed.
The noise of A naturally aspirated four-stroke scraper increases by 30dB (A) for every 10-fold increase in speed, and the noise increment of a four-stroke supercharged
scraper is 40dB for every 10-fold increase in speed. If there is a noise peak wave in the process of growth, it is the problem in the identification of noise sources,
and 1/3 octave spectrum analysis can be used to initially identify the main noise components.
The vibration and noise of the engine of the tripartite internal combustion scraper is the main source of the vibration and noise of the loader. The exciting force on the
scraper can be divided into the direct exciting force of combustion and the mechanical force when the scraper is working. When the engine of the three-way internal
combustion scraper is turned off, we should not worry and follow the above method step by step.
