Failure Detection of the Automatic Equipments

Detection automation equipments should include the following parts, power including the power supply of each device and the workshop of the power line frequency, gas source including the source of air pressure required for pneumatic devices. Hydraulic source should include the automation equipment hydraulics pump. Due to the negligence of equipment maintenance personnel, there may be the location of some of the sensor errors, such as place disorders, sensor failures and sensitivity fault. Users should always check the sensor location, sensitivity of the sensor, deviation of the timely adjustment, if the sensor is broken, then replace it immediately.

In pneumatic or hydraulic systems, the throttle valve opening degree and the pressure valve of the adjusting spring should also change with the vibration of the device and loose or sliding parts. They are not the same as ore beneficiation equipment and sand washing machine, these devices , sensors and automation equipment are needed to carry out routine maintenance parts. View circuit conductors to see whether there is a break, especially check the wire to ensure if it is due to pull trough cut off. Check the tracheal whether damage to the crease. Check the hydraulic hoses to see if they are not blocked. The trachea serious creases should be immediately replaced. The hydraulic tubing just have to be replaced. Relays and magnetic induction sensors, long-term use can also occur. Ground adhesions can not guarantee the normal electrical circuit and it thus needs to be replaced.
