1. Ensure that the ambient temperature of the optical fiber laser cutting machine is higher than 5 ℃ to meet the normal working conditions of the machine;

　　2. 如果光纖激光切割設備的溫度高于5℃，激光水箱應始終處于工作狀態。水箱的恒溫系統將保證光纖激光切割機的水系統始終處于水箱的設定溫度。如果發生停電，應及時發現。水箱內裝滿防凍液，比例為3:7。加入防凍劑后，不凍可抵抗-20℃。但是，由于防凍液有一定的腐蝕性，所以請注意冬季后更換正常的冷卻水，并在此之前清洗整個航道，清洗防凍液;

　　2. If the temperature of optical fiber laser cutting equipment is higher than 5 ℃, the laser water tank should always be in working condition. The constant temperature system of the water tank will ensure that the water system of the optical fiber laser cutting machine is always at the set temperature of the water tank. In case of power failure, it shall be found in time. The tank is filled with antifreeze at a ratio of 3:7. After adding antifreeze, it can resist - 20 ℃. However, due to the corrosiveness of antifreeze, please pay attention to replace the normal cooling water after winter, and clean the whole channel and antifreeze before that;

　　三、如果長時間停止光纖激光切割機各水路系統的排水。

　　3、 If the drainage of each water system of the fiber laser cutting machine is stopped for a long time.

　　1. 激光排水法:切斷水管后，將氣槍對準出口吹水，排出激光內部的水。

　　1. Laser drainage method: after cutting off the water pipe, aim the air gun at the outlet and blow water to discharge the water inside the laser.

　　2、水箱排水方法:打開水箱下部排水閥，排水水箱，必要時可將水冷卻器傾斜一定角度，使出口為點。管道排水:用壓縮空氣分別從低溫水和高溫水的進出口吹一分鐘，從水箱出口排水。泵頭排水:在每個泵頭的下部有一個水螺桿,當水冷隊長需要停止和運輸時間,打開泵頭螺絲把所有的水水泵,更好使用壓縮空氣吹起來,然后水螺絲收緊。過濾器、deion罐排水:打開過濾器，deion罐下部排水閥或有機玻璃外殼可以排出剩余的水。

　　2. Water tank drainage method: open the drain valve at the lower part of the water tank to drain the water tank. If necessary, tilt the water cooler to a certain angle to make the outlet the lowest point. Pipeline drainage: blow compressed air from the inlet and outlet of low-temperature water and high-temperature water for one minute respectively, and drain water from the outlet of water tank. Pump head drainage: there is a water screw at the lower part of each pump head. When the water cooling team leader needs to stop and transport time, turn on the pump head screw to pump all the water pumps. It is better to use compressed air to blow up, and then tighten the water screw. Filter, deion tank drainage: open the filter, the drain valve at the lower part of deion tank or the plexiglass shell can discharge the remaining water.
