Description

Technical Field

[0001] The utility model relates to the technical field of diesel generator sets, and more specifically, to a multifunctional oil tank of a diesel generator set. Background Art

[0002] The working principle of a diesel generator set is to utilize the principle of the diesel engine's internal combustion cycle, generate heat energy by burning diesel, and then convert the heat energy into mechanical energy to drive the generator to generate electricity. The high-temperature and high-pressure gas generated by the combustion of diesel inside the diesel engine drives the piston to move, thereby driving the crankshaft to rotate, and ultimately driving the generator to rotate to generate electricity. As a common power generation equipment, diesel generator sets have important application value in emergency backup power supply and temporary power supply.

[0003] In the existing technology, the existing fuel tanks do not have a heating function. In the extreme weather in the north in winter, the diesel in the tank is easily affected by the cold air and reaches the freezing point and solidifies, causing the diesel generator to fail to work, seriously affecting the working efficiency of the diesel generator. The oil cap of the existing fuel tank is not tightly sealed, which can easily cause the diesel to volatilize or be contaminated, affecting the quality of the diesel. At the same time, when observing the oil level in the tank, the staff generally observes it directly with the naked eye, but the liquid level in the tank is easily affected by light and other aspects, which is very inconvenient to observe and the judgment is prone to deviation.
