Embodiment 2
[0036] In order to realize the automatic monitoring of various operating parameters of the gas storage tank 9, the present invention provides an energy-saving oil-injected screw air compressor control system. The information collection device is provided with multiple interfaces, and each interface corresponds to a sensor. Specifically, the sensors include a temperature sensor 131, a pressure sensor 132, a flow sensor 133, and an air quality sensor 134. Each sensor is connected to the gas outlet of the gas storage tank 9, so that the system can automatically determine the temperature of the gas output by the gas storage tank 9. , Pressure, flow, and air quality are monitored, and the monitored parameters are sent to the signal acquisition device 13, and the signal acquisition device 13 sends the received monitoring information to the control device 12.
Embodiment 3
[0038] In order to realize the full automation of the system, simplify the work complexity of the staff, reduce the workload of the staff, and further ensure the safety of the staff, the present invention provides an energy-saving oil-injected screw air compressor control system, the control device 12 and the control The panel 14 is connected, and the control device 12 displays the received monitoring information on the control panel 14. The staff can intuitively see the operating status of the system through the control panel 14, and quickly understand the malfunctioning equipment, necessary At that time, the staff can stop the operation of the system according to the current operating conditions of the system, which is conducive to improving the efficiency of system operation, ensuring the safe operation of the system, and further ensuring the safety of the staff.
