Common fault detection in automation equipment

　　Any automation equipment is made up of three parts: the actuator, the sensor part and the controller part of the automation equipment. When an automation equipment suddenly fails to work, or the working sequence is out of order, it is necessary to carry out a fault diagnosis. Here we look at the three parts that make up the equipment to find out how to diagnose faults in automation equipment.

　　1. Check all power, gas and hydraulic sources of the automation equipment. Problems with the power, air and hydraulic supplies can often lead to faults in automation equipment. For example, problems with the power supply, including the entire workshop power supply failure, such as low power supply, burnt out insurance, poor contact with the power plug, etc.; air pump or hydraulic pump is not turned on, pneumatic triplex or duplex is not turned on, the hydraulic system in the relief valve or certain pressure valve is not opened, etc. Automatic hanger insert hook machine The following aspects should be included when testing automated equipment: power supply, including the power supply of each device and the power electricity of the workshop. Air source, including the air pressure source required for the pneumatic device. The hydraulic source, including the operation of the hydraulic pumps needed for the hydraulic devices of the automation equipment.

　　2. Check for offset sensor positions on the automation equipment. Due to negligence on the part of the equipment maintenance personnel, there may be errors in the position of certain sensors, such as not being in place, faulty sensors, faulty sensitivity, etc. The sensing position and sensitivity of the sensors should be checked frequently, and deviations should be adjusted in time, and sensors should be replaced immediately if they are broken.

　　3. Check the relays, flow control valves and pressure control valves of the automation equipment. Relays, like magnetic induction sensors, will also become lapped and sticky after long-term use, thus failing to ensure the normal electrical circuit and needing replacement.

These devices, like sensors, are components in automated equipment that require routine maintenance. Automatic insert hook screen printing machines

　　4. Check the electrical, pneumatic and hydraulic circuit connections. If none of the above three steps reveal any problems, then check all circuits. Look for broken wires in the circuit, especially in the wire grooves that have been cut by the wire grooves due to pulling. Check the air hoses for damaging creases. Check that the hydraulic fluid lines are not blocked. If the air hose is badly creased, replace it immediately. Replace the hydraulic oil hose as well. 5.

　　5. After ensuring that the above steps are correct, the fault may only appear in the controller of the automation equipment, but it can never be a programming problem. First of all, do not be sure that the controller is ruined. As long as there has not been a serious short circuit, the controller has internal short circuit protection and a general short circuit will not burn up the controller.
