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. 如果光纤激光切割设备的温度高于5℃，激光水箱应始终处于工作状态。水箱的恒温系统将保证光纤激光切割机的水系统始终处于水箱的设定温度。如果发生停电，应及时发现。水箱内装满防冻液，比例为3:7。加入防冻剂后，不冻可抵抗-20℃。但是，由于防冻液有一定的腐蚀性，所以请注意冬季后更换正常的冷却水，并在此之前清洗整个航道，清洗防冻液;

　　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、如果长时间停止光纤激光切割机各水路系统的排水。

　　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:切断水管后，将气枪对准出口吹水，排出激光内部的水。

　　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:打开水箱下部排水阀，排水水箱，必要时可将水冷却器倾斜一定角度，使出口为点。管道排水:用压缩空气分别从低温水和高温水的进出口吹一分钟，从水箱出口排水。泵头排水:在每个泵头的下部有一个水螺杆,当水冷队长需要停止和运输时间,打开泵头螺丝把所有的水水泵,更好使用压缩空气吹起来,然后水螺丝收紧。过滤器、deion罐排水:打开过滤器，deion罐下部排水阀或有机玻璃外壳可以排出剩余的水。

　　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.
