Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
Referring to fig. 1 and fig. 2, the intelligent control system for the screw air compressor unit disclosed by the invention comprises an air compressor unit, a fault detection component, a fault alarm component and a control system. The control system comprises an upper computer and a control panel, wherein the control panel adopts a touch screen and is in signal connection with the upper computer. The air compressor unit comprises two normally working air compressors 1 and a standby air compressor 1, wherein each air compressor 1 is connected with production equipment 7 through a conveying pipeline 2 and conveys compressed air to the production equipment 7. Every air compressor machine 1 all with upper computer electrical connection, when the air compressor machine 1 of normal work breaks down, can break down trouble air compressor machine 1 through the upper computer, open reserve air compressor machine 1 simultaneously, overhaul the air compressor machine 1 of trouble under the condition that does not influence production.
The fault detection assembly comprises a drive motor 12 fault detection assembly and a delivery pipeline 2 leakage detection assembly. The driving motor 12 fault detection assembly comprises photoelectric sensors 3 arranged on the inner side wall of each air compressor 1, and the transmitting ends of the photoelectric sensors 3 face the fan blade direction of the driving motor 12 in the air compressor 1. Conveying pipeline 2 leak testing subassembly is including setting up first gas pressure sensor and the second gas pressure sensor on every conveying pipeline 2, and first pressure sensor 4 is located the one end of being close to 1 output of air compressor machine, and second pressure sensor 5 is located the one end of keeping away from 1 output of air compressor machine. The photoelectric sensor 3, the first pressure sensor 4 and the second pressure sensor 5 are all in signal connection with an upper computer. The fault alarm assembly comprises an alarm 6 arranged on a shell 11 of each air compressor 1, and the alarm 6 is in signal connection with an upper computer. The alarm 6 adopts a three-color alarm lamp and can respectively display red, yellow and green colors.
