What are the common faults of Ningbo automation equipment?

Release time: 2019-11-20 9:01:30

Any automation equipment consists of three parts: the actuator, the sensor part, and the controller part. When the automation equipment suddenly fails and does not work, or the work order is abnormal, it must be diagnosed. Below we take a look at the three parts of the device to find out how to diagnose the failure of the automation equipment.

  1. Check all power, air, and hydraulic sources of the automation equipment.

Problems with power, air and hydraulic sources can often cause automation equipment to fail. For example, there is a problem with the power supply, including the fault of the entire workshop power supply, such as low power supply, burned out of the insurance, poor contact of the power plug, etc.; the air pump or hydraulic pump is not turned on, the pneumatic triple or the two-piece is not opened, and the relief valve in the hydraulic system Or some pressure valves are not open, etc. The following aspects should be included when testing automation equipment: power supply, including the power supply of each equipment and the power supply of the workshop. The air source, including the air pressure source required for the pneumatic device. Hydraulic sources, including the operation of hydraulic pumps required for automated equipment hydraulics.

  2. Check the sensor position of the automation device for an offset.

Due to the negligence of equipment maintenance personnel, there may be errors in the position of some sensors, such as not in place, sensor failure, sensitivity failure, etc. Always check the sensor's sensing position and sensitivity, and adjust the deviation in time. If the sensor is broken, replace it immediately. Many times, in addition, due to the vibration of the automation equipment, most of the sensors will be loose after a long period of use, so in the routine maintenance, always check whether the sensor is in the correct position and is firmly fixed.

3. Check relays for automatic equipment, flow control valves, pressure control valves

Like the magnetic inductive sensor, the relay can also be stuck in the long-term use, so that the electrical circuit cannot be guaranteed to be normal and needs to be replaced. In pneumatic or hydraulic systems, the throttle opening and the pressure regulating spring of the pressure valve may also loosen or slide as the device vibrates. These devices, like sensors, are components that require routine maintenance in automated equipment.

4. Check electrical, pneumatic and hydraulic circuit connections

If no problems are found in the above three steps, then all circuits are checked. Check if there is any open circuit in the circuit, especially if the wire in the wire slot is broken by the wire slot. Inspect the air tube for damaging creases. Check if the hydraulic hose is clogged. If the trachea has a serious crease, replace it immediately. The hydraulic tubing should be replaced.

5. After ensuring that the above steps are correct, the fault can occur in the controller of the automation device, but it can never be a program problem. First of all, don't be sure that the controller is destroyed. As long as there is no serious short circuit, the controller has short-circuit protection inside. The general short circuit will not burn the controller.
