Common troubleshooting methods for automation equipment
With the continuous introduction of manufacturers, automation equipment has become a weapon for the majority of manufacturers to improve efficiency and reduce costs. Any mechanical automation is composed of three parts: the actuator, the sensor part and the controller part. When the automatic machine suddenly fails to work, or the program is in disorder, it is necessary to detect the fault.
Let's take a look at the three parts that make up the machine and equipment to understand the way to diagnose automated mechanical failure. Verify all switching power supplies, air sources, and hydraulic sources for mechanical automation. Problems with power, air and hydraulic sources can often cause automated mechanical failure. For example, there is a problem in the power supply system, including the failure of the power supply system of the entire production workshop, such as low power supply, damaged fuse, poor contact of the power cord plug, etc.; the air pump or hydraulic pump is not opened, the pneumatic triple or the two-piece is not opened, the hydraulic transmission system The relief valve or some pressure valves are not open.
When testing automated machinery, the following aspects should be included: check the power supply, including the power supply system of each machine and the power supply of the production workshop. Check the air supply, including the air pressure source required for the pneumatic equipment. Check the hydraulic source, including the working conditions of the hydraulic pump necessary for the automated mechanical hydraulics. 2. Check whether the specific position of the sensor of the automated machine is biased. Due to the omission of the equipment maintenance management staff, there may be some errors in the position of the sensor, such as no work in place, common faults in the sensor, and common faults. It is necessary to frequently check the specific position and sensitivity of the sensor, and the error is adjusted in time. If the sensor is damaged, it will be replaced immediately. In addition, because of the vibration of the automatic machinery, most of the sensors are in a loose position after long-term application. Therefore, it is necessary to check the specific position of the sensor during normal maintenance. Not placed firmly.
3. Inspection of automatic machinery relays, flow control valves, pressure control valves Relays and magnetic induction sensors, long-term application will also have the situation of grounding adhesion, and thus can not ensure the normal control circuit of electrical equipment, must be replaced. In pneumatic or hydraulic transmission systems, the throttle opening and the pressure of the pressure valve adjust the yellowing, which can also be loose or dragged with the vibration of the machine. These devices are the same as the sensors, and all of them are parts that need to be properly maintained in automated machinery. 4. Check electrical, pneumatic and hydraulic circuit connections. If no problems are encountered in the above three steps, then all control circuits are checked. Find out if the wire in the power circuit is broken, especially if the wire in the wire slot is broken by the wire slot. Check if the trachea has damaged creases. Check if the hydraulic hose is blocked. If the bronchus is more severely creased, replace it immediately. The hydraulic tubing must be replaced.
