由于數控焊接設備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，這里山東數控焊接設備廠家為您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。

Because the CNC welding equipment needs to use gas as cutting raw material, the relevant pipe and gas path especially needs to attract the attention of the operator in the daily use process. Here, the Shandong CNC welding equipment manufacturer lists some common pipe and gas path faults and solutions for you, hoping you can learn from them.

要說明的是，管氣路故障是指除了因為切割燃氣氣壓、流速以及純度等參數的關注外的氣管氣路故障，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，重則造成燃燒或者炸。

It should be noted that the failure of the gas pipeline refers to the failure of the gas pipeline in addition to the concern of the cutting gas pressure, flow rate, purity and other parameters. If the accident is caused by the blockage or leakage of the gas pipeline, the harm is often quite huge, ranging from affecting the cutting quality to burning or explosion.

1、減壓閥的故障維修

1. Troubleshooting of pressure reducing valve

對減壓閥的故障維修應調節減壓器，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 the failure maintenance of the pressure reducing valve, the pressure reducer should be adjusted first, and the pressure gauge should be adjusted to the required pressure. During the adjustment process, the pressure should be adjusted from small to large to ensure that the pressure reducer can be continuously adjusted. If it cannot be adjusted continuously or the gas leaks from the safety valve, a new pressure reducer must be replaced. Self-folding the components of the gas pressure reducer will cause equipment damage and even serious personal injury.

2、氣路系統故障維修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。

2. There are two main aspects of common gas path maintenance for gas path system fault repair. In addition to regular inspection of the gas path system, the gas leak and parts that cannot be used normally should be handled in time to ensure the smooth gas path; The dust and sundries in the gas circuit should also be cleaned regularly to prevent premature aging of the gas circuit.

3、割炬割嘴故障及維護

3. Failure and maintenance of cutting torch and nozzle

在配件選購上，我們建議用戶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，須用專門工具修復。另外割炬也采用專門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。割嘴污染了需用專門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 sealing 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 a special manufacturer. For new cutting nozzle, it can only be used after passing the inspection. The cutting nozzle is polluted. It is necessary to use special tools to clean the preheating flame hole and cut the 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，一定請專門的人員更換。

The flashback preventer is an important part to ensure safety. According to the requirements of the safety department, it is forbidden to disassemble the flashback preventer without permission. Therefore, if the flashback preventer is used for a long time and the gas resistance cannot meet the gas flow requirements or leaks, it must be replaced by a special person.
