Abstract
The utility model relates to an energy saving control device for the hydraulic system, comprising a detection switch, a control button, a PLC programmable controller and a transducer, wherein, the detection switch and the control button are respectively connected with the input end of the PLC programmable controller connected with the input end of the transducer, while the output end of the transducer realizes connection with the input end of the hydraulic oil pump motor; besides, the control button comprises a start switch and a stop switch for starting and stopping the whole hydraulic system. By the technical proposal, the utility model is able to save the electric efficiency by 10 percent to 15 percent generally, and moreover due to the intermittent control method, the electricity saving effect is more obvious, even up to 30 percent, thereby applicable for the intermittent hydraulic transmission device.
Description
Technical field
The utility model relates to the hydraulic system field, relates in particular to, a kind of energy-saving control device that is used for hydraulic system.
Background technique
At present, a lot of hydraulic transmission equipments are when operation, and its load output much all is intermittent, i.e. during hydraulic-pressure pump motor acting, it is full load operation, and working time is shorter.And when the hydraulic system short time was failure to actuate, the hydraulic-pressure pump motor was but all the time in the i.e. idle running of running continuously.And, the general now star triangle reduced voltage starter starting electrical machinery that adopts of a lot of high-power Oil pump electrical machineries, but this starter, be not suitable for motor and carry out frequent start-stop at short notice, because of the inrush current of frequent starting is bigger, fragile probe of contactor, causes power network fluctuation and damage unfavorable factors such as electrical machine insulation.Not only, run counter to desire toward the contact meeting so adopt this mode starting electrical machinery can not reach energy-saving effect.
Summary of the invention
The utility model provides a kind of simple, safe and reliable energy-saving control device for various intermittent hydraulic transmission equipments uses at deficiency of the prior art.
In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals:
A kind of energy-saving control device that is used for hydraulic system, comprise detecting switch, control knob, PLC programmable controller and frequency variator, described detecting switch, control knob are connected with the input end of PLC programmable controller respectively, described PLC programmable controller is connected with the frequency variator input end, and described inverter output terminal is connected with hydraulic-pressure pump motor input end.
As preferably, described control knob comprises and starting and the enable switch and the stop switch of stop solution pressing system.
As preferably, described detecting switch is an optoelectronic switch.
As preferably, described detecting switch is a position limit switch.
As preferably, described detecting switch comprises optoelectronic switch and position limit switch.
As preferably, described position limit switch is 2, and described optoelectronic switch is 1.
A kind of energy-saving control device that is used for hydraulic system by the technical solution of the utility model design, send into the PLC programmable controller by the detected oil pump service data of each detecting switch, discern the working state and the load condition of Oil pump electrical machinery by the PLC programmable controller, make the oil pump energy-saving run to send deceleration or stop signal to frequency variator, and oil pump is when restarting work, only needing that also actuating signal is imported the PLC programmable controller gets final product, PLC sends actuating signal to frequency variator again, does not have the impact type soft start.The electric energy of frequency variator generally just can reach 10%-15% like this, and adds this intermittent control method, and its power savings is more obvious, even can reach the power savings more than 30%.

Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail:
As shown in the figure, a kind of energy-saving control device that is used for hydraulic system, comprise detecting switch 8, control knob 9, PLC control knob 5 able to programme, frequency variator 6 and hydraulic-pressure pump motor 7, described detecting switch 8 is installed on the oil pump of hydraulic system, it comprises 1 optoelectronic switch 3 and 2 position limit switches 4, it all is connected with the input end of PLC programmable controller 5 respectively, described control knob 9 comprises enable switch 1 and stop switch 2, it all is connected with the input end of PLC programmable controller 5 respectively, as shown in Figure 1, enable switch 1 is connected with the P00 pin of controller 5, stop switch 2 is connected with the P01 pin of controller 5, optoelectronic switch 3 is connected with the P03 pin of controller 5,2 position limit switches 4 respectively with the P05 of controller 5, the P07 pin is connected.Described PLC programmable controller 5 is connected with frequency variator 6 by relay K 1, and the output terminal of frequency variator 6 is connected with hydraulic-pressure pump motor 7.
During startup, press enable switch 1, given actuating signal input PLC programmable controller 5, PLC programmable controller 5 sends actuating signal to frequency variator 6 again, do not have the impact type soft start by frequency variator 6 to hydraulic-pressure pump motor 7, can regulate in frequency variator 6 its starting time.In the running, each detecting switch is sent into PLC controller 5 to detected service data, and PLC controller 5 is discerned the working state and the load condition of hydraulic-pressure pump motor 7 according to program.When PLC controller 5 detected the effectively long halted signals of hydraulic press, PLC sent to frequency variator 6 and slows down or stop signal makes the oil pump can energy-saving run.
The technical solution of the utility model, its detecting switch 8 can also be selected different quantity and type according to the employed occasion of different hydraulic systems, generally also can all select position limit switch 4 for use or all select optoelectronic switch 3 for use.
The above only is preferred embodiment of the present utility model, and all equalizations of being done according to the utility model claim change and modify, and all should belong to the covering scope of the utility model patent.
