Abstract

The invention discloses a fuel oil circulating filter system, an oil tank and an engineering machine. The fuel oil circulating filter system comprises a circulating oil conveying circuit arranged outside the oil tank and communicated with the oil tank, wherein the circulating oil conveying circuit is provided with a circulating pump and a filter device for filtering fuel oil. Therefore, the fuel oil circulating filter system can improve the fuel oil filter precision, and can reduce the on-way resistance of an oil conveying pipeline.

Description

technical field [0001] The invention relates to the field of construction machinery, in particular to a fuel circulation filter system, a fuel tank and construction machinery. Background technique [0002] At present, hydraulic excavators are widely used in many fields of national economic construction, especially in Inner Mongolia, Xinjiang, Shanxi and other places in northern my country, which have rich mineral resources. High frequency of use. [0003] Among them, the engine is one of the key components of the hydraulic excavator. The fuel supply system is an important part of the engine. reliability. [0004] However, in working environments such as open-pit coal mines and quarries, the ambient dust content is high, and the fuel oil is limited by transportation and storage conditions. Usually, the quality is not good, and the particulate matter and moisture content in the fuel oil are high. However, with the development of modern internal combustion engine technology a...
