The invention discloses a double-oil-tank oil way switching system of a fuel filter. The system comprises an auxiliary oil tank filter, a main oil tank filter, a change-over valve assembly and a filter tank assembly, and the inner end of an oil inlet of the main oil tank filter and an oil outlet of the main oil tank filter are both connected to the main oil tank filter; the inner end of an oil inlet of the auxiliary oil tank filter and an oil outlet of the auxiliary oil tank filter are connected to the auxiliary oil tank filter; and the inner end of the oil outlet of the main oil tank filter and the inner end of the oil outlet of the the auxiliary oil tank filter are connected to an engine oil supply port through a main and auxiliary oil tank oil supply change-over valve, and an engine oil return port is connected to the inner end of an oil return port of the main oil tank filter and the inner end of an oil return port of the auxiliary oil tank filter through a main and auxiliary oil tank oil return change-over valve. The double-oil-tank oil way switching system of the fuel filter is compact in structure, high in integration degree, low in leakage risk, low in production cost and high in switching efficiency, the valve clamping risk is reduced, and the risk that an engine cannot be started due to oil mixing at the low temperature is reduced.
本发明公开了一种燃油滤清器的双油箱油路切换系统,包括副油箱滤清器、主油箱滤清器、转换阀组件、滤罐组件,主油箱滤清器进油口内端、主油箱滤清器出油口均连接至主油箱滤清器上,副油箱滤清器进油口内端、副油箱滤清器出油口均连接至副油箱滤清器上;主油箱滤清器出油口、副油箱滤清器出油口的内端均通过主副油箱供油转换阀连接至发动机供油口上,发动机回油口通过主副油箱回油转换阀连接至主油箱滤清器回油口和副油箱滤清器回油口内端。本发明燃油滤清器的双油箱油路切换系统,结构紧凑,集成化程度高,泄漏风险低,生产成本低,降低卡阀风险,切换效率高,降低低温时混油导致发动机无法启动的风险。
