The variable frequency air compressor and the Ding frequency air compressor are linked to control, that is, a single air frequency air compressor and multiple Ding frequency air compressors are used in the same compressed air supply station to form a gas supply system, which provides stable gas supply network. Compressed air source. In the gas supply system, the variable frequency air compressor is used as the main machine, and the other Ding frequency air compressor is used as the slave. The variable frequency air compressor and the Ding frequency air compressor operate in linkage, which can avoid the frequent loading, unloading and start-stop of the network hollow press, avoid damage to the equipment and reduce the impact on the power grid, thereby achieving the effect of energy saving and environmental protection. 1 Linkage control network connection No. 1 is the inverter, set it as the master, and the rest of the air compressor is set as the slave. A maximum of 16 air compressors can be operated in the network. The linkage control network needs to use the communication line with good shielding effect to connect the communication ports A and B of the network hollow press controller in parallel. In the wiring process, it is best to avoid strong electrical interference, and the signal line and the power line separate the different pipes. The network connection structure is not intended to be the same. 2 Setting method of linkage control system Step 1: Enter user parameters when the device is stopped. Will be internalized. The letter mode option is set to linkage. The communication code is set to: 0001. -ij' frequency converter No. 2 machine No. 3 machine No. 4 machine No. N machine frequency conversion host slave machine slave machine slave machine network connection structure diagram Step 2: The linkage state is set to: host. Set the number of linkages according to the actual situation of the user. Step 3: Set the lower limit of linkage pressure, the upper limit of linkage pressure and the pressure of variable frequency. Note that the lower limit value of the linkage pressure and the upper limit value of the linkage pressure should be between the supply pressure of the single unit and the supply pressure of the single unit. The pressure value of the variable frequency should be set within the range of the linkage pressure upper limit value and the linkage pressure lower limit value. The specific relationship is as good as it is. 0.00MP gas supply plus linkage dynamic pressure frequency conversion union dynamic pressure gas supply unloading pressure force lower limit for pressure force upper limit plant pressure various pressure relationship in the device has stopped state into the user parameters. Set the communication mode option to linkage. The communication code is set to: 0002-0016. Note that the gas production volume m3/min gas production load is about 100% z load about 30% load frequency conversion machine\about 5丨0%,: 1 frequency machine about 25% gas production volume 5.7 frequency conversion machine No. 1 Power frequency machine No. 2 power frequency machine running time gas volume change conclusion The main function of air compressor linkage control is to intelligently complete the loading, unloading, starting and stopping of air compressor according to the pressure of the pipeline and the operating state of the air compressor. Action to ensure the stability of the pressure of the gas supply system. The energy-saving control technology of frequency conversion air compressor and Ding frequency air compressor provides more stable air supply pressure for the production of on-site gas, which makes the quality of the product more controllable, realizes energy saving and environmental protection, reduces cost consumption and improves airspace. Safety and reliability of press operation. Compared with the parameter adjustment of a single air compressor, the linkage energy-saving control technology of the air compressor overall system is of great significance.
