Ⅳ、安装说明
1、泵宜安装在干燥，通风，清洁的场合；
2、泵与电机共用一块底板，底板与地面相接触。地面应坚实平坦，泵安放应平稳着实。用地脚螺栓把泵固定于地面，泵四周应留适量拆装维修空间。
3、泵与被抽容器连接可用软管或金属硬管，用金属硬管时，可在管道上附加橡胶管，金属波纹管或内射弹簧的塑料软管过渡，以减少振动和改善接头密封；
4、电动机转向应与泵上旋转方向一致，不允许倒转。按电机标牌规定连接电源，地线以及相当容量保险丝等保护电机安全的措施。
5、泵进气管道按真空系统普遍原则，应尽量的大，尽量的短，尽量的光，尽量的干净，尽量少的弯头，以减少抽速损失。
6、为避免停泵时泵内油返入被抽容器，宜在泵口配置真空截止阀和充气阀。目前简便的方法在泵口配置相应规格的一台电磁真空带充气阀 （DDC-JQXX）即可，此阀的开、关与泵开，停同步进行。

Ⅴ、使用
1、断续启动泵（次数不宜过多），观察泵油面处于油标中横线附近一点，则可投入正常运转；油面过低，可停泵加油至油标中心横线，如油面过高，则需停泵放油至油标中心横线附近，否则会有显著喷油；
2、当环境温度低于5℃而难以启动泵时，可将油放出加热至20-30℃再加入到泵中，然后再启动泵，或者用电炉置于泵旁边加温。
3、当抽除带可凝性蒸汽的气体时，可打开气镇阀运转30-60min甚至更长一点时间，以利于可凝气体排除，延长泵油的使用寿命；
4、允许泵温≤（油温-环境温度）=40℃，当大于40℃时，需对泵加强通风散热；
5、进气温度应控制不高于40℃。
6、停泵后务必关闭气镇阀，以防漏油。

Ⅵ、维护与保养
1、经常注意油位在正常运转时油面处于油标中心横线附近,不要过高也不过低；同时注意油的质量变化状况，当油位明显上升或油色呈乳白（黄）状时，说明泵内进了水或其他物质，需检查排除。
2、换油期限：一般新泵建议在运转满100小时左右换一次，这样一、二次之后方可加长换油期限，如若被抽容器内抽出的是干燥清洁的空气时，建议可在500-1000小时换油一次；
如果被抽出的气体有腐蚀性或会与泵油起化学反应时，为不影响真空度，则除在气体进入泵之前进行予先处理外，还可用勤换油的办法弥补。
对存放期限长的泵往往极限压力达不到出厂名牌上的指标值，此时可密闭泵口开气镇阀抽气4小进左右即可；必要时可换油；
换油方法：密闭进气口，开泵0 .5小时，再从放油孔放油，然后进气口在大气压下抽气0.5min，同时从进气口缓慢加入少量清洁真空泵油，用以置换泵内存油，并保持润滑，在其放出后旋紧放油螺塞后，从加油孔加入新油，注意勿让颗粒杂物混入油中。
泵油一般采用SY1634-701号真空泵油。
3．泵应根据不同的使用条件订制不同的定期检修的制度。原则是：
（1）一般情况下抽除的气体干燥且干净的，建议可在泵使用2000小时后检修。
（2）新泵投入运转满500小时后对排气阀进行一次检修，以后可酌情延长或缩短检修周期。
（3）泵运转过程中发现泵油易被污染，或油（泵）温高或对橡胶和其他另件有化学作用的状况，可根据实际情况缩短检修周期，并及时更换易损件。
（4） 泵出现异常排气声及油面波动时，应及时检查排气阀片的工作状况。
