由于数控火焰切割机需要以燃气作为切割原料，在日常的使用过程中，相关管气路尤其需要引起操作者的注意，这里山东自动焊接设备厂家列举了一些常见的管气路故障及处理办法，希望大家能有所借鉴。

As the CNC flame cutting machine needs to use gas as cutting raw material, the relevant pipe gas circuit needs to be paid special attention to by the operator in the daily use process. Here, Shandong automatic welding equipment manufacturer lists some common pipe gas circuit faults and treatment methods, hoping that you can learn from them.

1、减压阀的故障维修

1. Troubleshooting of pressure reducing valve

对减压阀的故障维修先应调节减压器，将压力表调到需用的压力，调节过程中应使压力由小到大，确保减压器能连续调节。如不能连续调节或气体从阀中泄漏就须更换新的减压器。自行折装气体减压器之零部件，将会造成设备损坏，甚严重人身伤害。

For fault maintenance of the pressure reducing valve, the pressure reducer shall be adjusted first, and the pressure gauge shall be adjusted to the required pressure. During the adjustment process, the pressure shall be increased from small to large to ensure that the pressure reducer can be continuously adjusted. In case of continuous adjustment or gas leakage from the safety valve, a new pressure reducer shall be replaced. Self assembling the parts of the gas pressure reducer will cause equipment damage or even serious personal injury.

2、气路系统故障维修

2. Fault maintenance of air circuit system

常见气路维护主要有两方面，除可经常检查气路系统，发现漏气及不能正常使用的零部件应及时处理，保证气路畅通外；还应经常擦拭气路的灰尘及杂物，防止气路过早老化。

There are two main aspects of common gas path maintenance, except that the gas path system can be frequently inspected, and the parts and components that are found to be leaking and cannot be used normally should be handled in time to ensure that the gas path is unblocked; In addition, the dust and sundries in the air path shall be cleaned frequently to prevent premature aging of the air path.

3、割炬割嘴故障及维护

3. Fault and maintenance of cutting torch and nozzle

在配件选购上，我们建议用户好使用厂家提供的原厂机用，在长期的使用过程中，割炬密封面损坏，与割嘴密封不严，须用专用工具修复。另外割炬也采用厂家生产的标准快速割嘴，对于新割嘴，须经检查合格方可使用。割嘴污染了需用专用工具清理预热火焰孔及切割氧通道。

In the purchase of accessories, we recommend that users use the original machine provided by the manufacturer. In the long-term use process, the sealing surface of the cutting torch is damaged and the seal with the cutting nozzle is not tight, so special tools must be used to repair. In addition, the cutting torch also adopts the standard quick cutting nozzle produced by professional manufacturers. The new cutting nozzle can be used only after passing the inspection. The cutting nozzle is polluted. Special tools are required to clean the preheating flame hole and the cutting oxygen channel.

4、回火防止器的维修

4. Maintenance of flashback preventer

回火防止器是保证的重要部件，根据部门的要求，回火防止器严禁私自拆卸。因此，回火防止器使用久后气阻，保证不了气体流量要求时或漏气，一定请人员更换。

The flashback preventer is an important part to ensure safety. According to the requirements of the safety department, it is strictly prohibited to disassemble the flashback preventer without permission. Therefore, if the gas resistance of the flashback preventer cannot meet the gas flow requirements or leaks after a long time of use, it must be replaced by professional personnel.

如果因气管气路堵塞或泄露造成事故，其危害往往是相当巨大的，轻则影响到切割质量，重则造成燃烧或者更严重的后果。所以对于该设备的故障问题要趁早进行解决才行，更多内容就来我们网站http://www.tayfsk.com咨询了解吧。

If an accident is caused by the blockage or leakage of the gas pipeline, the harm is often very great, which may affect the cutting quality, or cause combustion or more serious consequences. Therefore, the failure of the equipment should be solved as soon as possible. For more information, please visit our website http://www.tayfsk.com Consult and understand.
