Digital all-metal detection machines are a precise electrical equipment. There may be small problems in the daily use process. There are many reasons for failure. In order to prevent a digital metal detection machine from faults in use, it is necessary to do maintenance and maintenance. Let's take a look at how to maintain a metal detection machine.

The scope of the inspection is as follows:
1. Electrical insulation inspection
Equipment maintenance personnel should check the lineplate parts, distribution boxes, wiring, etc. of the digital metal detection machine every week, and find that there are problems such as loosening, falling off, and short connection of connectors, and make corresponding treatment.

2. Power supply voltage check
Using a multimeter to measure the power supply of the metal detection machine, the normal situation should be kept within the AC220V positive and negative 22V. If the voltage fluctuates too large, it will affect the digital metal detection equipment. Long -term abnormal voltage abnormalities are likely to cause damage to the metal detection equipment line. The problem of abnormal voltage can be solved by installing AC voltage voltage power.

3. Compressed air pressure examination
Under the normal working state of digital metal detection machines, the compressing air pressure is greater than 0.5MP. Too small air pressure will cause the exclusion mechanism to move slowly and affect the accuracy of the exclusion. In addition Without other impurities, the detectors can use the system to "maintain the operation screen" to control the movement of the mechanism. When the action is connected, the solenoid valve is connected to exclude a series of actions without delay in the mechanism. If there is an abnormal phenomenon, timely repair the air compressor, replace the solenoid valve, etc.

4. Check the inspection of the test machine
Detecting equipment maintainers enter the system "maintenance operation screen" and start the conveyor belt through the control button. Under normal circumstances, the motor starts and the conveyor belt runs smoothly. If there is a problem that the conveyor belt does not start, check whether the fuse is burned, whether the relay controls the motor is damaged, and replace the relevant accessories in time, so that the transmission part can run smoothly, otherwise the detection accuracy of the digital metal detection machine will decrease.

5. Inspection accuracy inspection of metal detectors and gold inspection machines
Aircraft inspection, connect the power supply of the device, press the start -up button on the operating panel of the detection machine, the system starts, the machine indicates the lights, and the metal detection has begun after restoring Changliang. If you do n’t call the police, check whether there is a source of pollution. After the problem is eliminated, take the iron, non -iron, and stainless steel test block (the golden inspection machine manufacturer will accompany a standard test block before the equipment leaves the factory). Put on the conveyor belt to see if the alarm can be generated, and record the accuracy that the current digital metal detector machine can detect. If the detection accuracy does not meet the requirements, the corresponding changes can be changed by the sensitivity adjustment in the product configuration.
