Abstract
The invention discloses a frequency conversion and energy conservation device of a hydraulic system with lower energy consumption, which is composed of an oil tank, a plurality of outlet tubes connected with the oil tank, a hydraulic pump connected with the oil tank via a pipeline, and a motor connected with the hydraulic pump, wherein the motor is connected with a frequency converter which is provided with a signal change-over board connected with the frequency converter, and the signal change-over board is connected with a flow sensor arranged in the oil tank via leads. The device in the invention has the advantages of being capable of checking the actually required power of the hydraulic system, performing frequency conversion adjustment on the motor so as to obtain proper power, avoiding idlework and lowering the energy consumption of the hydraulic system.
Description
Technical field
The present invention relates to a kind of hydraulic system, relate 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.
Summary of the invention
Technical problem to be solved by this invention 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 used in the present invention 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.
Advantage of the present invention is: 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, and 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 present invention is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is the structural representation of hydraulic system frequency converting and energy saving device of the present invention.
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 present invention is described; and be not to be limitation of the present invention; the those of ordinary skill in relevant technologies field; without departing from the spirit and scope of the present invention; can also make various variations and modification, so all technological schemes that are equal to also should belong to protection category of the present invention.
