Abstract

The invention discloses an oil tank for an excavator hydraulic system. The oil tank comprises an oil suction tank, a net-type oil filter, an oil filtering net, an air vent, an oil returning pipe, a top cover, an oil level indicator, a separator and an oil draining plug. The net-type oil filter is a returning-type oil filter. The air vent is arranged on the upper portion of the oil tank. An air filter is arranged at the top of the oil suction tank. The bottom of the oil tank is inclined, and the oil draining plug is located at the bottom of the oil tank. By the manner, failures of the hydraulic system can be reduced, hydraulic oil and power can be saved, and thus, using cost of the hydraulic system can be reduced.

Description

A kind of fuel tank for excavator hydraulic system
Technical field
The present invention relates to the excavation machinery field, particularly relate to a kind of fuel tank for excavator hydraulic system.
Background technique
The pollution of hydraulic system is one of hydraulic system major reason of producing fault, shows according to some data both at home and abroad: abroad the fault major part that takes place of hydraulic system since pollution cause, and may also can be higher in this ratio of China.China's hydraulic product is having bigger gap qualitatively with external hydraulic product, and the gap of polluting control is one of most important reason.It is bad that fuel tank pollutes this link control, and with the harm that some hydraulic systems are polluted throughout one's life, fault takes place frequently, and reduces the working life of oil hydraulic pump, other hydraulic element and the life time of hydraulic oil greatly, wastes energy, and increases the use operating cost of equipment.
The main function of fuel tank in hydraulic system is: store for the required fluid of systemic circulation; The heat that produces during emanation system work; Release is mixed in the gas in the fluid; For the installation of element in the system provides the position.Fuel tank should in time be removed the dirt that precipitates in the fluid, and the fluid in fuel tank must make and meet the fluid that the hydraulic system turbidity test require.Fuel sucking pipe and return tube should be tried one's best at a distance of far away, will separate with dividing plate between two pipes, to increase the fluid cycling distance, make fluid that the time enough separate bubbles be arranged, precipitated impurities, dissipation heat.The dividing plate height is preferably 3/4 of the interior fuel head of case.The return tube of fuel tank should be located at below the fluid liquid level as far as possible, in order to avoid oil return fluid impacts fuel tank inner fluid liquid level, makes to produce bubble in the fluid, causes cavitation, and hydraulic system is produced harmful effect.
Summary of the invention
The technical problem that the present invention mainly solves provides a kind of hydraulic oil container, and the present invention can reduce the fault of hydraulic system, saves the hydraulic oil that uses, and saves the energy, thereby reduces the user cost of hydraulic system.
For solving the problems of the technologies described above, the technological scheme that the present invention adopts is: a kind of fuel tank for excavator hydraulic system is provided, comprise: oil suction case, screen filter, oil cleaner screen, vent, return tube, top cover, fuel level indicator, dividing plate and oil drain plug, described screen filter is back the formula oil purifier, the top of described fuel tank is provided with vent, described oil suction box top is provided with air-strainer, and described fuel tank bottom is inclination, and described oil drain plug is positioned at the bottom of fuel tank.
In a preferred embodiment of the present invention, described fuel tank is open type oil tank.
In a preferred embodiment of the present invention, the actual volume of described fuel tank is 12 L 5-175L.
In a preferred embodiment of the present invention, described fuel tank wall thickness is 5mm.
In a preferred embodiment of the present invention, the material of described fuel tank is Ordinary Steel.
The invention has the beneficial effects as follows: the fault that can reduce hydraulic system of the present invention, save the hydraulic oil that uses, save the energy, thereby reduce the user cost of hydraulic system.

Embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present invention is described in detail, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that protection scope of the present invention is made more explicit defining.
See also Fig. 1, the embodiment of the invention provides following technological scheme
In one embodiment, a kind of fuel tank for excavator hydraulic system, comprise: oil suction case 1, screen filter 2, oil cleaner screen 3, vent 4, return tube 5, top cover 6, fuel level indicator 7, dividing plate 8 and oil drain plug 9, described screen filter 2 is back the formula oil purifier, the top of described fuel tank is provided with vent 4, described oil suction box top is provided with air-strainer, and described fuel tank bottom is inclination, and described oil drain plug 8 is positioned at the bottom of fuel tank.
Preferably, described fuel tank is open type oil tank.
Preferably, the actual volume of described fuel tank is 12 L 5-175L.
Preferably, described fuel tank wall thickness is 5mm.
Preferably, the material of described fuel tank is Ordinary Steel.
The present invention saves the hydraulic oil that uses, the saving energy, thereby the effect of the user cost of reduction hydraulic system by the fault that the present invention can reduce hydraulic system.
The above only is embodiments of the invention; be not so limit claim of the present invention; every equivalent structure or equivalent flow process conversion that utilizes specification of the present invention and accompanying drawing content to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present invention.
