no. 1 Embodiment approach
[0032] exist figure 1 In the figure, the structure of the oil supply type screw air compressor which concerns on 1st Embodiment of this invention is shown schematically. In addition, an air compressor is a device that compresses air.
[0033] Oil-supply screw air compressor 100 (hereinafter sometimes simply referred to as "compressor 100") drives compressor main body 3 with motor 4, removes dust in the atmosphere with suction filter 1, and sucks dust from the atmosphere through suction throttle valve 2. Air is sucked into the compressor body 3 . The sucked atmospheric air is pressurized by the compressor main body 3, and the compressed air is discharged from the discharge port of the compressor main body 3 when the pressure reaches a predetermined pressure. In this embodiment, the compressor body 3 is constituted by a pair of screw rotors and the like.
[0034] The compressed air from the compressor main body 3 flows into the oil separation tank 6 to separate it into compre...
no. 2 Embodiment approach
[0071] The waste water discharge control of compressed air discharges waste water intermittently by turning on and off the waste water discharge solenoid valve at regular intervals. This control is turned on and off at intervals that can handle the maximum amount of waste water that is supposed to be generated. Therefore, when the humidity is low, not only waste water but also compressed air are discharged, so compressed air is wasted.
[0072] exist Figure 7 In , the control flow chart which can make the wastewater discharge interval appropriate by acquiring temperature and humidity information is shown.
[0073] In the present embodiment, the amount of waste water generated when changing the temperature and humidity around the compressor 100 is recorded in advance in the storage device 133 of the compressor control circuit board, and the temperature and humidity information is read from the cloud 23, thereby combining it with Accordingly, waste water is properly discharged...
no. 3 Embodiment approach
[0079] When the compressor 100 is installed in a cold region, even if the operation of the compressor 100 is stopped for a certain period of time, the internal temperature of the compressor drops to the same level as the surrounding air temperature. From this state, when the temperature around the compressor 100 rises sharply, the temperature of the internal components of the compressor cannot keep up with the surrounding changes, and the temperature remains low. risk of rust. In electronic components, there is a possibility that a short circuit on a circuit board may occur due to dew condensation, resulting in a malfunction.
[0080] exist Figure 8 In FIG. 2 , a control flow of the drying operation inside the compressor 100 performed based on the acquired air temperature information is shown. In this embodiment, when the information of a sudden temperature change is obtained from the weather information, the intermittent forced load operation of the compressor 100 or the p...
