Failure of the plasma cutter is caused by improper operation and commissioning
For the maintenance of plasma cutters, it is important to identify problems, In particular, the external fault of the plasma cutting machine. Sometimes the diagnostic process is more complex, but once a problem is identified, it is easier to solve. External troubleshooting should follow two principles: First, we need to be proficient in how plasma cutters work and sequence their movements. Second, use THE PLC ladder map for diagnosis.
The status display function of the NC system or external programmer monitors the operating status of the PLC. In general, as long as you follow the above principles and be careful, the failure of the general plasma cutter will be eliminated in a timely manner.
The soft failure of the plasma cutter is caused by improper operation and commissioning. Most of these failures occur in the early stages of using plasma cutters or in the adjustment period for equipment users. For plasma cutters, the servo unit is another prone to failure. Because the movement of the axes is achieved by the servo unit control servo motor to drive the gears. The rotary encoder is used for speed feedback and motor positioning is used for position feedback. In general, the prone to failure is the drive module of the rotary encoder and the server unit. The power supply can also cause some system confusion. Ideal for systems with computer hard drives to hold data.
Some failures do not generate fault alert information, but the operation cannot be completed. At this time, it is necessary to analyze and judge according to maintenance experience, the working principle of plasma cutting machine and the operating state of PLC.
In the feed transmission system of the plasma cutter, the role of the rail is to support and guide the moving parts in order to carry on the reciprocating linear motion in a given direction. If the guide rail of the plasma cutter fails, measures should be taken in a timely manner. There are several ways to fix the fault of the plasma cutter rails:
1. Adjust the gap between the wedge rod and the support plate to reduce the friction between the support plate and the rail and improve the motion accuracy;
2. Adjust the pretension force, adjust the loose part, eliminate the transmission gap, etc., can improve the drive accuracy.
3. Paste the plastic guide to ensure that the plastic rod is intact;
4. The gap between the rail and the rail should not be stolen, there must be good protective gear;
5, static pressure guide should have a set of oil supply system, filtration effect is good;
6. Timely, quantitative and accurate lubrication of each moving part.
There are often a lot of tips in plasma cutters, but they can make our daily work uncomfortable, so if you're having problems at work, keep your head clear to solve the problems we encounter well.
