In the process of daily use of truss manipulator, you may encounter different problems, which can cause some unnecessary loss to the enterprise. So how to avoid and solve these problems? Here Tongli will share the solution skills with you.
1.Troubleshooting, debugging
For the debugging and fault coexistence of electrical equipment, you should first troubleshoot, and then debug. Debugging must be carried out under the condition that the electrical circuit is normal.
2.First check outside and then inside
You should first check the surface of the equipment for obvious cracks, defects, to understand its maintenance history, age, etc. And then you can check the internal inspection of the machine. You should exclude the surrounding fault factors, determine the fault for the machine before dismantling. Otherwise, blind disassembly may be the more equipment repair the worse, causing unnecessary losses.
3. First check mechanical parts after the electrical parts
Only after determining that the mechanical parts of hoist are fault-free, you can carry out the electrical aspects of the inspection. When checking the circuit failure, you should use the testing instrument to find the fault area. After confirming that there is no poor contact fault, and then targeted to view the relationship between the operation of the line and the machinery to avoid misjudgment.
4.Replacement of electrical parts, first peripheral and then internal
Do not rush to replace the damaged electrical parts of the manipulator, and consider replacing the damaged electrical parts after confirming that the peripheral equipment circuit is normal.
5.Daily maintenance, DC first and then AC
When inspecting, you must check the static working point of DC circuit first, and then check the dynamic working point of AC circuit.
6.Find the reason before repairing when you occur failure
For the faulty truss loading and unloading electrical equipment, do not rush to do, you should first ask the fault before and after and the fault phenomenon. For the rusty equipment,you should also be familiar with the circuit principle and structural characteristics first, and comply with the corresponding rules. Before disassembly, you should be fully familiar with the function, location, connection and relationship with other devices around of each electrical component, and in the absence of assembly diagram, draw sketch and mark while disassembling.
7. Static first and then dynamic
When the truss manipulator is not energized, judge the electrical equipment buttons, contactors, thermal relays and fuses so as to determine where the fault lies. You can power on test, listen to its sound, measure the parameters, judge the fault, and then repair. For example, when the motor is out of phase, if the measurement of three-phase voltage value can not be discerned, you should listen to its sound and measure the relative voltage alone, in order to determine which phase is defective.
8. Maintenance, clean first and then repair
For heavily polluted electrical equipment, first clean its buttons, junction points, contact points, and then check whether the external control keys are out of order. Many faults are caused by dirty and conductive dust blocks. Once cleaned, faults are often eliminated.
9. Power supply first and then equipment
The failure rate of daily truss loading and unloading power supply part accounts for a high proportion of the whole faulty equipment, so the power supply can often be overhauled first with half the effort.
