Abstract

The invention discloses a clean fuel tank and construction machinery. The clean fuel tank comprises a tank body 1, a floater 2 capable of floating on oil and an oil supply hose 3, wherein two ends of the oil supply hose 3 are open. An oil supply mouth 4 is arranged in the bottom of the tank body 1. The floater 2 is arranged inside the tank body 1. One end of the oil supply hose 3 is connected with the floater 2 and the surface of the other end of the oil supply hose 3 is connected with the oil supply mouth 4 in a sealing mode. According to the clean fuel tank, the oil on the upper layer can be guided out through the floating floater and the oil supply hose, impurities away from the bottom of the fuel tank can effectively prevent oil sludge, scrap iron and other impurities which are deposited on the bottom of the fuel tank, the service life of a first-level filter of a fuel system is greatly prolonged, and stability of using of an engine is greatly improved.

Description

Technical field [0001] The invention belongs to the field of machinery manufacturing, and relates to an engine fuel tank, in particular to a clean fuel tank for engineering machinery and engineering machinery. Background technique [0002] In the fuel supply system of the engine, in order to improve the fuel quality, a multi-stage filter fuel system is often applied. As the first-stage oil-water separator, the fuel tank has a higher filtering accuracy and often clogging failures, which makes the engine difficult to start or unable to start, or work weak. [0003] The reason is that the large particles in the fuel tank enter the fuel pipe through the fuel suction port and accumulate in the first-stage filter. Therefore, the upstream oil processing of the fuel system needs to be improved. [0004] In order to improve the cleanliness of the fuel, the engineering machinery factory has been doing the work of improving the accuracy of the filter element after the fuel tank. Improving the...
