Abstract
The utility model discloses a hydraulic system of an energy-saving type rubbish transfer station and relates to a hydraulic system of a compressing oil cylinder of a rubbish transfer station. The hydraulic system of the energy-saving type rubbish transfer station comprises an oil tank (1), an oil supply pump (2), an oil supply pipeline (3), an oil return pipeline (4) and a compression oil cylinder (5). The oil tank (1) is connected with the compression oil cylinder (5) through the oil supply pipeline (3) and the oil return pipeline (4), and the oil supply pump (2) is arranged on the oil supply pipeline (3). The hydraulic system of the energy-saving type rubbish transfer station further comprises a first electromagnetic valve (6), a second electromagnetic valve (7) and a third electromagnetic valve (8), the second electromagnetic valve (7) is connected with a rod cavity of the compression oil cylinder (5) and a rodless cavity of the compression oil cylinder (5), the first electromagnet valve (6) is connected with the oil supply pipeline (3) and the rodless cavity of the compression oil cylinder (5), and the third electromagnetic valve (8) is connected with the second electromagnetic valve (7) and the oil return pipeline (4). The hydraulic system of the energy-saving type rubbish transfer station solves the problem that a small-power oil pump is adopted in the rubbish transfer station so as not to meet the requirement for rubbish compression.
Description
Technical field
The utility model relates to the hydraulic efficiency pressure system of garbage transfer station pressing oil.
Background technology
In the garbage transfer station, need to be with garbage-compressing, to close in transportation and to process.In the garbage-compressing, generally adopt hydraulic efficiency pressure system rubbish is compressed and to squeeze.Prior art is the purpose that reaches energy-conservation, generally adopts the miniwatt oil pump, but the miniwatt oil pump flow is little, can't satisfy the requirement of rubbish squeezing.
Summary of the invention
The utility model provides a kind of energy-saving garbage transfer station hydraulic efficiency pressure system, and the utility model has solved garbage transfer station and adopted the miniwatt oil pump, can't satisfy the problem that the rubbish squeezing requires.
For addressing the above problem, the utility model adopts following technical scheme: a kind of energy-saving garbage transfer station hydraulic efficiency pressure system comprises fuel tank (1), oil feed pump (2), oil feed line (3), oil return line (4) and pressing oil (5); Fuel tank (1) is connected 4 by oil feed line (3) with oil return line) connect pressing oil (5), at oil feed line (3) oil feed pump (2) is installed; Also comprise the first electromagnetic valve (6) and the second electromagnetic valve (7) and the 3rd electromagnetic valve (8); The second electromagnetic valve (7) connects respectively the rod chamber of pressing oil (5) and the rodless cavity of pressing oil (5); The first electromagnetic valve (6) connects the rodless cavity of oil feed line (3) and pressing oil (5); The 3rd electromagnetic valve (8) connects the second electromagnetic valve (7) and oil return line (4).
Characteristics of the present utility model: 1, when oil cylinder descends, electromagnetic valve 6,7 energisings are opened, change by system, the hydraulic oil of cylinder rod chamber is supplied with oil cylinder rodless cavity with oil pump, satisfy the large flow of little oil pump, low power purpose, reach the effect (equipment dynamic is little, is equivalent to reduce power 45%) of energy-conserving and environment-protective; 2, when oil cylinder rises, electromagnetic valve 8 is opened, oil rise (so be that rod chamber to flow do not require because oil cylinder rises).
Description of drawings
Fig. 1 is the utility model structural representation.
Nomenclature among the figure: fuel tank (1), oil feed pump (2), oil feed line (3), oil return line (4), pressing oil (5), the first electromagnetic valve (6), the second electromagnetic valve (7), the 3rd electromagnetic valve (8).
The specific embodiment
The below is described in detail the utility model with best embodiment.
As shown in Figure 1, a kind of energy-saving garbage transfer station hydraulic efficiency pressure system comprises fuel tank (1), oil feed pump (2), oil feed line (3), oil return line (4) and pressing oil (5); Fuel tank (1) is connected 4 by oil feed line (3) with oil return line) connect pressing oil (5), at oil feed line (3) oil feed pump (2) is installed; Also comprise the first electromagnetic valve (6) and the second electromagnetic valve (7) and the 3rd electromagnetic valve (8); The second electromagnetic valve (7) connects respectively the rod chamber of pressing oil (5) and the rodless cavity of pressing oil (5); The first electromagnetic valve (6) connects the rodless cavity of oil feed line (3) and pressing oil (5); The 3rd electromagnetic valve (8) connects the second electromagnetic valve (7) and oil return line (4).
The utility model system works pressure: 21MPa; System works flow: 91L/min; Electromagnetic valve voltage: DC 24V; Working medium: HL-32(or HL-46) hydraulic oil.
It should be noted that at last: obviously, above-described embodiment only is for the utility model example clearly is described, and is not the restriction to embodiment.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here need not also can't give all embodiments exhaustive.And the apparent variation of being amplified out thus or change still are among the protection domain of the present utility model.
