Control System Design of Detection Device for Pipe Air Tightness Based on Water Test Method

Abstract:

Traditional water test method has the advantage of locating leaks can be found, the disadvantage is inefficient manual detection, labor-intensive, can not be automated testing. By analyzing pneumatic and PLC control were introduced, pneumatic system of the detection device was designed, combined with operation process of the pneumatic circuit PLC control system was designed. Through the PLC control solenoid valve opening and closing, thereby control the implementing agencies of the pneumatic circuit, the device complete each course of action to achieve the test. Application of the system has maintained the advantages of the water detection assay, achieved a semi-automated detection, increased the detection efficiency, reduced labor intensity, and easy to operate.
