Abstract
The utility model discloses a variable frequency energy-saving device with low energy consumption for a hydraulic system, which comprises an oil tank, a plurality of oil outlet pipes connected with the oil tank, a hydraulic pump connected with the oil tank through an oil pipe, and an electric motor connected with the hydraulic pump, wherein the electric motor is connected with a frequency converter, and a signal converter plate connected with the frequency converter is arranged on the frequency converter and is also connected with the flow sensor in the oil tank through a conducting wire. The utility model has the advantages that the actually required power in the hydraulic system can be detected, and the variable frequency adjustment is performed to the electric motor, thereby obtaining suitable power without idle work and reducing the energy consumption of the hydraulic system.
Description
Technical field
The utility model relates to a kind of hydraulic system, relates in particular to a kind of frequency converting and energy saving device that is used on the hydraulic system.
Background technique
In press, oil hydraulic press, injection machine, blow-moulding machine etc., all be provided with hydraulic system.The structure of hydraulic system mainly comprises: fuel tank, the some oil outlet tubes and the return tube that are connected with fuel tank, and by the oil hydraulic pump that oil pipe is connected with fuel tank, the motor that is connected with oil hydraulic pump.During use, by the motoring oil hydraulic pump, oil hydraulic pump is exported constant compression force by oil pipe in fuel tank, and the pressure of oil hydraulic pump output is greater than the needed actual pressure of hydraulic system, and unnecessary pressure can oil be laid down pressure by return tube.Will cause motor to do a part of idle work more like this, not produce actual functional capability, power of electric motor is bigger, and energy consumption is higher.
The model utility content
Technical problem to be solved in the utility model provides the lower hydraulic system frequency converting and energy saving device of a kind of energy consumption.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: the hydraulic system frequency converting and energy saving device, comprise: fuel tank, the some oil outlet tubes that are connected with fuel tank, the oil hydraulic pump that is connected with fuel tank by oil pipe, the motor that is connected with oil hydraulic pump, be connected with frequency variator at described motor, be provided with coupled signal transducer at frequency variator, signal transducer is connected with flow transducer in being arranged on fuel tank by lead.
The utility model has the advantages that: above-mentioned hydraulic system frequency converting and energy saving device, can be checked through the actual power that needs of doing in the hydraulic system, motor is carried out variable frequency adjustment, the power that obtains being fit to does not flog a dead horse, and has reduced the energy consumption of hydraulic system.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is the structural representation of the utility model hydraulic system frequency converting and energy saving device.
Among the figure: 1, fuel tank, 2, oil outlet tube, 3, oil pipe, 4, oil hydraulic pump, 5, motor, 6, frequency variator, 7, signal transducer, 8, lead, 9, flow transducer.
Embodiment
As shown in Figure 1, the hydraulic system frequency converting and energy saving device, comprise: fuel tank 1, the some oil outlet tubes 2 that are connected with fuel tank 1, the oil hydraulic pump 4 that is connected with fuel tank 1 by oil pipe 3, the motor 5 that is connected with oil hydraulic pump 4, be connected with frequency variator 6 at described motor 5, be provided with coupled signal transducer 7 at frequency variator 6, signal transducer 7 is connected with flow transducer 9 in being arranged on fuel tank 1 by lead 8.
When above-mentioned hydraulic system frequency converting and energy saving device uses, detect the needed working pressure of hydraulic system by flow transducer 9, flow transducer 9 is passed to signal transducer 7 with detected signal by lead, signal transducer 7 is according to detected SC sigmal control frequency variator 6, frequency variator 6 changes the power of coupled motor 5, motor 5 drives oil hydraulic pump 4, and oil hydraulic pump 4 is exported the needed pressure of hydraulic system by oil pipe 3 in fuel tank 1.
The foregoing description is only for the usefulness that the utility model is described; and be not to be to restriction of the present utility model; the those of ordinary skill in relevant technologies field; under the situation that does not break away from the utility model spirit and scope; can also make various variations and modification, so all technological schemes that are equal to also should belong to protection category of the present utility model.
