Abstract
The utility model discloses a hydraulic energy-saving oil tank. A variable oil pump is arranged on the oil tank, provided with a pressure regulating rod, and sequentially connected with a pressure meter and an oil filter through a first oil pipe; an oil leakage port on the variable oil pump extends into the oil tank through a second oil pipe; an air-cooled type oil cooler is arranged on an outer surface of the second oil pipe; a liquid level control relay is arranged in the oil tank; and a liquid level and liquid temperature meter is arranged on the outer surface of the oil tank. According to the hydraulic energy-saving oil tank, a pressure-limiting type variable oil pump is adopted, and the pressure is self-regulated by a pump body. During pressure maintenance of a system, oil which is drained from the oil pump is greatly reduced, required electric energy is greatly reduced, leaked oil for maintaining the pressure of the oil pump is cooled in an air-cooling mode, the temperature of the oil tank no longer rises, and the performance of a hydraulic system is greatly improved.
Description
Technical field
The utility model belongs to mechanical equipment technical field, relates to a kind of hydraulic energy-saving fuel tank.
Background technique
Hydraulic oil container in the past adopts quantitative oil pump, relief valve pressure regulation.The pressure oil that oil pump is discharged when system's pressurize is more, and pressure oil is through the relief valve oil sump tank, and motor institute consuming electric power converts heat energy to, makes the fuel tank temperature rise the hydraulic system degradation.
Summary of the invention
The purpose of the utility model provides a kind of hydraulic energy-saving fuel tank, and the oil that oil pump is discharged when system's pressurize significantly reduces, and the fuel tank temperature can not rise.
The technological scheme that the utility model adopted is, the hydraulic energy-saving fuel tank, and fuel tank is provided with variable capacity oil pump, and variable capacity oil pump is provided with pressure adjusting lever, and variable capacity oil pump is connected with pressure gauge, oil purifier in turn through first oil pipe; Leakage hydraulic fluid port on the variable capacity oil pump extend in the middle of the fuel tank through second oil pipe, and the outer surface of second oil pipe is provided with air-cooled oil cooler, also is provided with level control relay in the fuel tank, and the fuel tank outer surface is provided with the liquid level liquid thermometer.
The characteristic of the utility model also is,
Fuel tank is provided with the hydraulic pressure air-strainer.
The hydraulic energy-saving fuel tank of the utility model adopts the limited pressure variable capacity oil pump, through the pump housing self adjustment pressure.The oil that oil pump is discharged when system's pressurize significantly reduces, and required electric energy significantly reduces, and oil pump is kept the leakage oil of pressure through air-cooled cooling, and the fuel tank temperature no longer rises, and the hydraulic system performance is significantly improved.
Description of drawings
Fig. 1 is the structural representation of the utility model hydraulic energy-saving fuel tank.
Among the figure, 1. variable capacity oil pump, 2. pressure adjusting lever, 3. pressure gauge, 4. level control relay, 5. oil purifier, 6. liquid level liquid thermometer, 7. air-cooled oil cooler, 8. the hydraulic pressure air-strainer 9. leaks hydraulic fluid port, 10. second oil pipe, 11. fuel tanks, 12. first oil pipes.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is elaborated.
The structure of the utility model hydraulic energy-saving fuel tank is as shown in Figure 1, and fuel tank 11 is provided with hydraulic pressure air-strainer 8, and the air that hydraulic pressure air-strainer 8 will get in the fuel tank 11 filters, and can be used as the oil filler of fuel tank 11.On fuel tank 11, also be provided with variable capacity oil pump 1, variable capacity oil pump 1 is provided with pressure adjusting lever 2, and pressure adjusting lever 2 is used for the pressure in the Moderator Variable oil pump 1.Variable capacity oil pump 1 is connected with pressure gauge 3, oil purifier 5 in turn through first oil pipe 12.Leakage hydraulic fluid port 9 on the variable capacity oil pump 1 extend in the middle of the fuel tank 11 through second oil pipe 10.The outer surface of second oil pipe 10 is provided with air-cooled oil cooler 7, is used for to 10 coolings of second oil pipe.Also be provided with level control relay 4 in the fuel tank 11, fuel tank 11 outer surfaces are provided with liquid level liquid thermometer 6.
The using process of the utility model hydraulic energy-saving fuel tank is that the oil that variable capacity oil pump 1 is discharged gets into oil purifier 5 through pressure gauge 3, by the oil entering valve plate of oil purifier 5 discharges.The height of level control relay 4 control liquid levels is also reported to the police.Liquid level liquid thermometer 6 is observed oil tank liquid level and temperature.Air-cooled oil cooler 7 is but imported oil sump tank 11 in the back with the oil cooling in the leakage hydraulic fluid port 9 of keeping system pressure on the variable capacity oil pump 1 and second oil pipe 10.The utility model fuel tank adopts the limited pressure variable capacity oil pump, through the pump housing self adjustment pressure.The oil that oil pump is discharged when system's pressurize significantly reduces, and required electric energy significantly reduces, and oil pump is kept the leakage oil of pressure through air-cooled cooling, and the fuel tank temperature no longer rises, and the hydraulic system performance is significantly improved.
