Abstract

The invention discloses an engineering machinery hydraulic oil tank with a filtering function. The oil tank comprises an oil tank body, an oil pump, a filter, a first oil pipe, a second oil pipe and a third oil pipe, wherein one end of the first oil pipe is connected with the oil tank body, the other end of the first oil pipe is connected with an oil suction port of the oil pump, one end of the second oil pipe is connected with an oil outlet of the oil pump, the other end of the second oil pipe is connected with an oil inlet of the filter, one end of the third oil pipe is connected with an oil outlet of the filter, the other end of the third oil pipe is connected with the oil tank body, the rated flow of the oil pump is 2-3 L/min, the rated flow of the filter is 60 L/min, and the filter class of the filter is 3 microns. The oil tank is compact in structure, novel and reasonable in design, capable of well filtering hydraulic oil in the oil tank body, prolonging the no-failure operation time of engineering machinery and improving the reliability of the engineering machinery greatly, and convenient to use and popularize.

Description

technical field [0001] The invention relates to the technical field of engineering machinery hydraulic systems, in particular to an engineering machinery hydraulic oil tank with a filtering function. Background technique [0002] For mechanical construction enterprises, whether the technical condition of construction machinery is good or not is a direct factor for the normal production of the enterprise. Most of the current construction machinery adopts electromechanical-hydraulic integration, and the normal operation of the hydraulic system is a major sign of its good technical condition. Due to the harsh working conditions of construction machinery, a large proportion of its failures are caused by hydraulic oil pollution, which seriously affects the reliability of construction machinery and the service life of the engine. The construction machinery oil tanks in the prior art either do not have a filtering function, or have a filtering function, but the filtering effect is...
