The compressed air supply device 5 is composed of a discharge flow rate determination circuit 6, an inverter 7, a pulse motor 8, a compressor 9, and a pressure switch 10. The inverter 7 outputs the pulse signal which converted the output frequency of the three-phase alternating current power supply 12 to the pulse motor 8. The pulse motor 8 rotates at a rotational speed proportional to the conversion frequency, and the fixed displacement compressor 9 discharges compressed air having a capacity corresponding to the rotational speed of the pulse motor 8. The discharge flow rate determination circuit 6 determines the conversion frequency of the inverter 7 based on the on-off of the pressure switch 10 and the on-off of the start switch 3 of the compressed air supply device.

In addition, the discharge flow rate specifying mode of the discharge flow rate converting means 7G, 8 is set to the determined discharge flow rate defining mode, and the detected pressure is set to the first stage when the use state transmission means Co is transferring the use mode. If the pressure is exceeded, the second discharge flow rate specification mode is selected. If the detected pressure is lower than the second reference pressure, the first discharge flow rate specification mode is selected. When the detected pressure exceeds the first reference pressure when the mode is switched to the use mode, the first specific discharge flow rate specifying mode is selected, and when the detected pressure is lower than the second reference pressure, the second specific discharge flow rate is defined. A method for supplying compressed air, wherein the selection of the discharge flow rate detection mode for selecting the mode is performed over a set period of time. 제1항에 있어서, 압축 공기 소비 장치는 공기 젯트 직기인 것을 특징으로 하는 압축 공기 공급 장치.The compressed air supply apparatus according to claim 1, wherein the compressed air consumption device is an air jet loom. 제2항에 있어서, 압축 공기 소비 장치는 공기 젯트 직기인 것을 특징으로 하는 압축 공기 공급 장치.The compressed air supply apparatus according to claim 2, wherein the compressed air consumption device is an air jet loom. 제3항에 있어서, 압축 공기 소비 장치는 공기 젯트 직기인 것을 특징으로 하는 압축 공기 공급 장치.4.
