Accompanying drawing explanation
Accompanying drawing 1 is the utility model catenation principle schematic diagram;
Accompanying drawing 2 is the schematic diagram of the utility model pressure regulator valve.
Embodiment
For the ease of the understanding of those skilled in the art, below in conjunction with accompanying drawing, the utility model will be further described.
As shown in figure 1 and 2, the utility model discloses a kind of air compressor energy-saving device of air, comprise air compressor, motor 4 and gas holder, air compressor is connected with motor 4, the outlet side of air compressor is connected with gas holder by pipeline, the inlet end attaching of described compressed air has selector valve 2, this selector valve 2 is connected with air filter 1, pressure regulator valve 3 is installed between air compressor and selector valve 2, this pressure regulator valve 3 is also connected with gas holder, gas holder is provided with pressure transducer, and this pressure transducer is connected with controller, is provided with failure bypass handover module in controller.
Pressure regulator valve 3 comprises valve body 10, there is in valve body 10 appearance air cavity, valve body 10 is provided with suction port and air outlet, suction port is connected with selector valve 2 by pipeline, and air outlet attaching has cylinder 7, is provided with motion bar 9 and piston 8 in this cylinder 7, motion bar 9 upper end is upwards just passing cylinder 7 to the suction port of valve body 10 and is stretching in the appearance air cavity of valve body 10, motion bar 9 lower end is connected with piston 8, and cylinder 7 is provided with gas interface 6, and this gas interface 6 is connected with gas holder by pipeline.The sectional area of motion bar is equal to, or greater than the area of suction port.Cylinder periphery is also provided with housing, and cylinder is accommodated in the inner by this housing, makes cylinder not fragile.
In addition, pressure transducer is arranged on the air outlet of gas holder inwall or gas holder.
The air being used for compressing use is filtered the impurity removed in air by air filter in advance, stops impurity to enter air compressor; Motor drives air compressor to do work to air, and output squeezing air, it is stand-by that pressurized air is carried out storage by gas holder.During startup optimization, the failure bypass handover module in controller carries out self-inspection to controller, if find, controller has fault, then make energy-saving controller jump to bypass condition, this bypass condition is equivalent to a sky and opens, and makes air compressor with its normal frequency operation; If controller does not have fault, then civil power is first powered to controller 5, and energy-saving controller 5 is powered to air compressor again, makes compressor operation.
The pressure transducer then real-time pressure to gas holder detects, the transducing signal of the gas holder inner air pressure of pressure transducer feedback regulates the voltage of supply air compressor, realize VFC, reach the optimum Match between supply gas pressure and rotational speed of air compressor, air compressor is made to ensure to run with minimum speed under the prerequisite of producing, thus reach the object of electricity saving and energy saving, greatly reduce the waste of the energy.Specifically, when the air pressure P in gas holder reaches after air pressure upper limit set value P1, pressure transducer passes to controller this information, controller compares the instant air pressure P of air in gas holder and setting value P1 value, and after carrying out data operation and processing, controller exports and is applicable to voltage master, the rotating speed of final adjustment air compressor motor, pressurized air air pressure needed for making the rotating speed of the motor of air compressor and producing reaches best fit, air compressor air feed air pressure can be made like this to control within more stable scope, optimize the power air feed of production, the power consumption of air compressor is made again greatly to be reduced.
In addition, when gas consumption increases, pressure drop in gas holder, then in piston 8 lower cylinder 7, gas pressure declines, such piston 8 will drive motion bar 9 to move down, thus adds the sectional area of suction port, and extraneous source of the gas is entered fast, air compressor acting will be accelerated like this, produce enough pressurized air as early as possible; On the contrary, when gas consumption reduces, in gas holder, pressure will rise, then in piston 8 lower cylinder 7, gas pressure increases, and such piston 8 will drive motion bar 9 to move up, thus reduces the sectional area of suction port, reduce extraneous source of the gas admission velocity, even take valve motion bar 9 to close suction port to valve body 10 and will reduce air compressor acting like this, produce less pressurized air, reduce air compressor energy consumption.
It should be noted that, the above is not the restriction to technical solutions of the utility model, and under the prerequisite not departing from creation design of the present utility model, any apparent replacement is all within protection domain of the present utility model.
