由于數控火焰切割機需要以燃氣作為切割原料，在日常的使用過程中，相關管氣路尤其需要引起操作者的注意，這里山東自動焊接設備廠家列舉了一些常見的管氣路故障及處理辦法，希望大家能有所借鑒。

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、減壓閥的故障維修

1. Troubleshooting of pressure reducing valve

對減壓閥的故障維修先應調節減壓器，將壓力表調到需用的壓力，調節過程中應使壓力由小到大，確保減壓器能連續調節。如不能連續調節或氣體從閥中泄漏就須更換新的減壓器。自行折裝氣體減壓器之零部件，將會造成設備損壞，甚嚴重人身傷害。

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、氣路系統故障維修

2. Fault maintenance of air circuit system

常見氣路維護主要有兩方面，除可經常檢查氣路系統，發現漏氣及不能正常使用的零部件應及時處理，保證氣路暢通外；還應經常擦拭氣路的灰塵及雜物，防止氣路過早老化。

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、割炬割嘴故障及維護

3. Fault and maintenance of cutting torch and nozzle

在配件選購上，我們建議用戶好使用廠家提供的原廠機用，在長期的使用過程中，割炬密封面損壞，與割嘴密封不嚴，須用專用工具修復。另外割炬也采用廠家生產的標準快速割嘴，對于新割嘴，須經檢查合格方可使用。割嘴污染了需用專用工具清理預熱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、回火防止器的維修

4. Maintenance of flashback preventer

回火防止器是保證的重要部件，根據部門的要求，回火防止器嚴禁私自拆卸。因此，回火防止器使用久后氣阻，保證不了氣體流量要求時或漏氣，一定請人員更換。

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.

如果因氣管氣路堵塞或泄露造成事故，其危害往往是相當巨大的，輕則影響到切割質量，重則造成燃燒或者更嚴重的后果。所以對于該設備的故障問題要趁早進行解決才行，更多內容就來我們網站http://www.opedost.com咨詢了解吧。

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.opedost.com Consult and understand.
