数控开料机水冷真空泵的使用及维护Use and Maintenance of Water-cooled Vacuum Pump for CNC Feeder

发布时间:2019-01-18点击量:47

温馨提示:寒冷的冬天真的很冷,为了确保我们的冷水机设备在冬季正常运行,现将水冷真空泵在冬季环境温度比较恶劣的情况下使用时的相关注意事项与保养方法与您讲解。

一、 在水箱中添加防冻液或乙醇防止水结冰。

1.在水箱里添加30%的乙二醇。一般情况下,添加20%左右的酒精可以将冰点降低到-10℃,添加40%的酒精能将冰点降低到-20℃,切记千万不要将酒精浓度超过40%,超过40%以后,水很容易蒸发,而且容易燃烧;

2.在水箱里添加50%的防冻液;

3.在水箱里添加25%的氯化钙水溶液。

二、 设备在使用时,要仔细观察出水、回水管路是否有结冰的现象。若结冰或邻近结冰则应向水箱里面加温水(﹤50 ℃)进行融化。

三、 真空泵在长时间不使用时,应该通过排污阀门将水箱里面的水以及过滤杯里面的水排尽,同时应拧开水泵底下的排水螺母将水泵里面残留的水排净;以防止环境温度过低致使水系统结冰。

Warm Tip: It's really cold in cold winter. In order to ensure the normal operation of our water chillers in winter, we will explain to you the relevant matters needing attention and maintenance methods when using the water-cooled vacuum pump under severe ambient temperature in winter.


First, add antifreeze or ethanol to the water tank to prevent water from freezing.


1. Add 30% ethylene glycol into the water tank.  In general, adding about 20% alcohol can lower the freezing point to -10℃, adding 40% alcohol can lower the freezing point to -20℃, remember never to exceed 40% alcohol concentration, water will evaporate easily and burn easily after exceeding 40%;


2. Add 50% antifreeze to the water tank;


3. Add 25% calcium chloride aqueous solution into the water tank.


Second, when using the equipment, carefully observe whether there is ice in the outlet and return water pipelines.  If there is ice or nearby ice, warm water (| 50℃) should be added into the water tank to melt.


Third, when the vacuum pump is not in use for a long time, the water in the water tank and the water in the filter cup should be drained through the drain valve, and the residual water in the water pump should be drained off by unscrewing the drain nut under the water pump.  In order to prevent the water system from freezing due to low ambient temperature.
