旋片式真空泵是一种油封式机械真空泵,是真空技术中最基本的真空获得设备之一。旋片式真空泵可以抽除密封容器中的干燥气体,若附有气镇装置,还可以抽除一定量的可凝性气体。但它不适于抽除含氧过高的,对金属有腐蚀性的、对泵油会起化学反应以及含有颗粒尘埃的气体。

旋片式真空泵的常见故障处理

1、旋片式真空泵的操作与维护

a. 泵的启动

启动前先检查水冷泵的冷却水是否接通,当环境温度较低时,可用手搬动皮带轮,使泵腔内的油排入油箱。然后按动电机按钮送电,注意电源方向是否接反,泵旋转方向是否正确。

b.泵运转注意事项

检查泵油量是否在油标线附近;接通被抽系统阀门时不要开得太快,防止大量喷油;运转中注意有无不正常的噪声和冲击声,注意泵的油温升高,有局部过热时立即停泵,防止卡泵或磨损。

c. 停泵注意事项

停泵一定要从泵入口放大气(一般购买的机组都有自动放气阀);断电后再断水。

d. 泵的维护与保养

不同牌号的泵油不要混用;定出合理的换油周期(与使用条件有关);泵从系统上拆下来时,泵口要塞封,防止脏物进入泵内;泵在使用中应保持所要求的环境条件。

2、旋片泵的维修

旋片式真空泵的常见故障,有以下几类:

①真空度降低;

②泵不能正常运转,甚至“卡死”;

③在运转中,有较大的噪音、杂音;

④泵体密封不好—漏油;

⑤在启动时,大量喷油滴、油雾,污染环境;

⑥启动困难。
