Abstract

The invention relates to a diesel engine external-cycle oil tank structure which comprises an oil-gas separator assembly (2), an oil tank internal oil return bayonet tube (3), a defoaming partition (4), a lubricating oil heat exchanger (6) and an oil tank longitudinal partition (9), wherein the middle part of the oil tank is divided into a front oil storage unit (10) and a back oil storage unit (11) by the oil tank longitudinal partition (9); the oil tank longitudinal partition (9) is aligned and welded with the upper edge of the oil tank; the back oil storage unit (11) comprises the oil tank internal oil return bayonet tube (3), the defoaming partition (4) and a diesel engine oil inlet (14); the front oil storage unit (10) is provided with an oil filler hole (011); and the oil-gas separator assembly (2) is arranged on the upper part of the back oil storage unit (11), and communicated with the cavity part of the back oil storage unit (11). The invention can discharge gas in an oil solution in time, and prevents the oil gas from polluting the surrounding environment. The invention can also be used for filtering the oil solution and controlling the oil temperature; and a liquid level indicator is utilized to observe the liquid level, and measure and record the liquid level variation.

Description

technical field [0001] The invention belongs to the technical field of high-power vehicle diesel engine testing, and in particular relates to a diesel engine external circulation oil tank structure. Background technique [0002] The diesel engine circulating oil tank is mainly composed of defoaming partitions, oil-gas separators, oil filters, heat exchangers and electric heaters. Since the high-power vehicle diesel engine is limited by the size of the vehicle, the height of the oil bottom is low, and it cannot meet the storage requirements of the minimum amount of diesel engine lubricating oil. Therefore, most of them need to be equipped with an additional oil tank to solve the cooling cycle, oil-gas separation and storage of lubricating oil. . Due to the inevitable gas leakage when the diesel engine is working, and due to the narrow space in the body, the lubricating oil is mixed with a large amount of gas under the double action of the crankshaft and other rotating parts...
