Collapse maintenance steps

Machine electrical troubleshooting can be divided into the following general steps:

(1) Preparation

Preparations include the preparation of the necessary tools, meters, machine tool diagrams and other information

(2) read the picture

For the machine to be repaired, we must first understand the circuit diagram.

(3) Through the "one question, two see, three touch, four listen, five operations" to figure out the phenomenon of failure and failure before and after the situation.

A question: Ask the machine operator to understand the situation before and after the failure occurred; failure occurred suddenly or frequently? What anomalies appear? What are the anomalies? And so on. This accurate grasp of the initial first-hand information, is conducive to determine the location of the fault occurred quickly identify the point of failure.

Second look: carefully observe the surface of machine tools or lines.

Third, listen to: start the machine, listen to the motor, control transformers, contacts, relays, etc. have abnormal sound and closed sound.

Four touch: When the machine running for a period of time, cut off the power, the hand mold on the electrical enclosure or solenoid coil, check for unusual phenomena such as fever.

Five operations: starting from the start, all the functions of the machine one by one operation of the demonstration, in a step by step operation carefully observe the operation process, find out the machine electrical fault, in order to facilitate the rapid and accurate determination of machine electrical fault range .

(4) According to the fault phenomenon combined with the circuit diagram Analysis of the approximate scope of the fault From the above "ask, see, listen, touch, operation" and other basic process of clarifying the phenomenon of failure, then the circuit diagram can be combined with the approximate scope of the fault, and then use the appropriate The detection method to identify the point of failure.

(5) replace the component fault point to find out, you need to replace the components.

Abnormal operation test

The purpose of abnormal operation test is to improve system reliability and avoid unnecessary accidents as much as possible. Abnormal operation test can be carried out as follows:

① external sudden power failure experiment. When the device is operating manually or automatically, no matter under what circumstances, for external sudden power outage, can be reliably stopped, and through the provisions of the steps to make the device back to normal operation.

② emergency breaking test. When the device is operated manually or automatically, the device can be stopped reliably and the normal operation can be resumed by the specified operating procedures, no matter under what circumstances, the emergency disconnection operation (such as pressing the emergency stop button on the control panel) .

③ test switch bad test. Should take into account the system detects the possibility of poor switch, especially for mechanical parts prone to collision, interference, the impact of safety components, stroke end of the signal should be tested for anomalous test, we must ensure that even if a test switch is bad or damaged, still not There will be a safety accident.

④ poor implementation of the test components. Should take into account the possibility of poor implementation of the system components, especially for easy to produce mechanical impact, interference, the impact of the safety of the executive components should be abnormal tests, we must ensure that even if an actuator is bad or damaged, will not be a safety accident .

⑤ protection circuit action test. Should take into account the possibility of system protection circuit action, especially for circuit breakers, automatic switching and other protective devices, abnormal tests should be carried out, we must ensure that the protection device operation, the device can reliably stop, and through the provisions of the steps, can Resume normal work.
