Abstract
The utility model provides a hydraulic oil tank of an independent oil return structure. The independent oil return chamber (7) of the oil tank comprises an oil return chamber (14) and a filter chamber (13), wherein, the independent oil return chamber (7) is directly welded inside the oil tank body (11); the bottom part of a return oil filter (5) is inserted into a filter spigot (8) at the bottom part of a filter chamber (13); a filter cover positioning pin (2) is inserted into the spigot of the filter cover positioning pin (4); a filter handle (15) is fixed between two positioning plates (16) of the filter cover (1); a spring (3) is arranged between the upper part of the filter (5) and the filter cover (1); the filter cover (1) is fixed on the oil tank body through bolts to compress the spring (3) to fix the filter (5). The hydraulic oil tank has the advantages that the filter can be replaced without discharging the oil in the oil tank, and the service and the maintenance are convenient and rapid; the fixation of the filter is stable, safe and reliable; the air filter on the hydraulic oil tank has the functions of ventilation and oiling filtration, and the cleaning port and the oil discharging port are conducive to the cleaning and oil change of the hydraulic oil tank.
Description
Technical field
The utility model relates to a kind of hydraulic oil container of model utility independence oil return structure
Background technique
At present, the installation majority of the oil return filter cleaner of loader hydraulic oil container is to be hung in fuel tank internal by steel pipe, and fluid passes through filter cleaner from inside to outside, the installation of filter cleaner and replacing trouble and unreliable.Because loader need often clean or change the oil return filter cleaner in the process of use, with the turbidity test of assurance hydraulic system, and then the stability of assurance machine.But present structure needs the hydraulic oil in the fuel tank is emitted and could be operated, and is unfavorable for services and repairs.
Summary of the invention
In order to overcome the problem that existing loader hydraulic system cleaned or changed oil return filter cleaner difficulty, the invention provides a kind of model utility loader hydraulic oil container, this hydraulic oil container adopts independent oil revolute chamber structure, fluid enters fuel tank after filtering through filter cleaner from outside to inside, and filter cleaner is installed the mode that adopts spring compression, cleaner bottom secction and the dual location of strainer cover.Do not need the oil in the fuel tank just emitted and to change filter cleaner, services and repairs aspect, quick.Filter cleaner fixing-stable, safety, reliable; Air-strainer is arranged on the hydraulic oil container, and air-strainer has effect ventilative and that oiling is filtered, and Butterworth Hatch and fuel outlet are convenient to the cleaning of hydraulic oil container inside and are changed oil.
The technological scheme that its technical problem that solves the utility model adopts is: in this device, independent oil revolute chamber directly is welded on hydraulic oil container inside, the oil return cleaner bottom secction inserts on the filter cleaner seam of independent oil revolute chamber bottom, locating stud on the strainer cover inserts in the seam of cleaner top section, handle on the filter cleaner is fixed between the positioning plate of strainer cover, spring is placed in the seam of cleaner top section and strainer cover, strainer cover is fixed on the hydraulic oil container, make length of spring compressed, filter cleaner is fixed.The beneficial effects of the utility model are: 1) owing to adopted independent oil back chamber structure, fluid filters to adopt and passes through filter cleaner from outside to inside, has avoided causing hydraulic oil to spume because of the oil return impact.1) because filter cleaner is installed the mode that adopts spring compression, filter cleaner lower curtate and the dual location of strainer cover, filter cleaner fixing-stable, safety, reliable, cleaning or change filter cleaner does not need the oil in the fuel tank is emitted, services and repairs aspect, quick.3) each element connection aspect is subjected to the restriction in space little, arranges easily.
