Abstract
The invention belongs to the field of engineering machinery, and particularly relates to cleaning of an online oil-way system assembled on a bulldozer. In order to achieve the purpose, an online filter system adopts the following technical schemes that an online oil filter device is connected to an oil way of the bulldozer through a pipeline at an assembly test stage of the bulldozer; an oil filter car pumps the oil in an oil tank into a filter core through a gear pump when a main machine carries out steering and braking maneuver, and the filtered oil is conveyed to the oil tank of the main machine again. The online filter system of hydraulic oil for the caterpillar bulldozer is characterized in that the main machine can rinse impurity and contamination particles in the pipeline into the oil tank after controlling steering and braking, and the oil containing the impurity in the oil tank is filtered by the online filter system to filter the impurity, so as to ensure a clean oil product in the oil tank. The online filter system has the beneficial effects that the impurity in the oil-way system of the bulldozer can be effectively removed by the online filter system, and the phenomena such as obstruction and valve blockage of the oil-way system are reduced.
Description
Technical field
The invention belongs to engineering machinery field, relate in particular to the cleaning that bulldozer assembles online oil-way system.
Background technique
At present, traditional bulldozer in when assembling because the bulldozer hydraulic oil pipe system is open system, no matter be in transportation or in assembly process, all there are various pollutions in component itself, all inevitable such as situations such as: mechanical admixture, dust pollution, turbidity test are poor.
The patent of invention content
The object of the invention is to overcome the deficiency of above-mentioned technology, and provide a kind of purging system that between erecting stage the main unit hydraulic pipe-line system is carried out on-line filtration at the bulldozer main frame, turbidity test with intrasystem pollutant washing and filtering, raising system reduce the possibility that oil circuit stops up.
The present invention for achieving the above object, adopted following technological scheme: be connected to on-line oil filter on the bulldozer oil circuit by pipeline in the bulldozer assembling test run stage, turn at main frame, shortening filter cart sucks filter core by gear pump with the oil in the fuel tank in the braking maneuver, is transmitted back to the main frame fuel tank through the oil that filters again.It is characterized in that: machinery trials is through turning to, the impurity in the pipeline, contamination particle can being flushed to fuel tank after the braking maneuver, and after filtering through the on-line filtration system, the impurity that comprises in the oil in the fuel tank is filtered out, and guarantees the cleaning of oil product in the fuel tank again.
Beneficial effect of the present invention: impurity in the bulldozer oil-way system can effectively be removed by this on-line filtration system, the phenomenons such as the obstruction of minimizing oil-way system, card valve.
Description of drawings
Figure of description is bulldozer on-line filtration systematic schematic diagram.
1. strainer 2. filterpumps 3. essences are considered device 4. braking in a turn valves 5. essences and are considered device 6. steering pumps 7. strainers 8. rear axle box
Embodiment
As shown in drawings, steering pump 6 work, oil in the rear axle box is got back in the rear axle box through behind strainer 7, secondary filter 5 and the braking in a turn valve 4, meanwhile, start filterpump 1, oil in the rear axle box 8 is got back in the rear axle box 8 and is circulated through strainer 1, filterpump 2, secondary filter 3, finishes the online circulating filtration of oil.
By above-mentioned embodiment, the online oil filtration system is flushed to the impurity in the pipeline in the rear axle box in the process of main frame braking in a turn system adjustment test run, oil in the rear axle box improves impurity absorption the turbidity test of oil product again at strainer or secondary filter through filtration system, obviously reduce the probability that the braking in a turn system oil-way blocks, blocks valve.
The above only is preferred embodiment of the present invention, is not principle of the present invention is done any pro forma restriction.Every foundation technical spirit of the present invention all still belongs in the scope of technological scheme of the present invention any simple modification, equivalent variations and modification that above embodiment does.
Claims (1)
1. crawler dozer hydraulic oil on-line filtration system.The present invention for achieving the above object, adopted following technological scheme: in the bulldozer assembling test run stage, on-line oil filter is connected on the bulldozer oil circuit by pipeline, turn at main frame, in the braking maneuver, shortening filter cart sucks filter core by gear pump with the oil in the fuel tank, is transmitted back to the main frame fuel tank through the oil that filters again.It is characterized in that: machinery trials can be flushed to fuel tank with the impurity in the pipeline, contamination particle after turning to, brake through manipulation, comprises the oil of magazine in the fuel tank filtering the impurity filtering through on-line filtration system process, guarantees the cleaning of the interior oil product of fuel tank.
