Accompanying drawing explanation
Fig. 1 is the schematic diagram of system of the present invention.
Detailed description of the invention
Fig. 1 is the schematic diagram of system of the present invention, as it is shown in figure 1, air compressor machine work system includes motor,
Motor is by the first switch 1 access power circuit, and motor controls air compressor machine, and air compressor machine connects drying machine；Dry
Dry machine connects multiple gas equipment by pipe network.Also including frequency conversion energy-saving system, frequency conversion energy-saving system is connected in parallel on
First switch 1 two ends, are provided with second switch 2 between frequency conversion energy-saving system and power circuit.At air compressor machine
Effusion meter is had with connecting in the middle of drying machine.It is provided with on pipe network between drying machine and multiple gas equipment
One valve 6, the first valve two ends are parallel with local supercharging device；It was provided with before local supercharging device
Two valves 4, are provided with the 3rd valve 5 after local supercharging device.
The most in the present system, air compressor machine energy-conservation, employ two kinds of technology, a kind of for making originally to make in work
Motor frequency conversion work in the case of Pin, then can arrange the operating frequency of motor according to the needs of practical situation,
Saving the energy, another kind is increase local supercharging device at far-end gas equipment, to the tables of equipment many with gas
Solely supercharging, and without increasing the air demand of total air feed equipment.
The system using test air compressor energy-saving rate as above carries out the method for testing tested, in this enforcement
In example, with 24 hours as measurement period.Specifically include following steps:
Step 1, test air compressor machine power frequency operation gas consumption ratio.First switch 1 closes, and second switch 2 is opened,
Make motor be directly accessed power circuit, run under the frequency of 50Hz；First valve 6 is opened, and second
