容积式泵的主要特点是:
1、流量几乎不随压力而变。
2、往复泵的流量和压力有较大脉动,回转泵一般无脉动或只有小的脉动。
3、往复泵是低速机械,回转泵转速较高,可达3000转/分。
4、往复泵适用于高压力和小流量;回转泵适用于中小流量和较高压力。总的来说,容积泵的效率高于动力式泵,一般为70~85%。
5、往复泵适宜输送清洁的液体或气液混合物,有的泵如隔膜泵可输送泥浆、污水等,主要用于给水、提供高压液源和计量输送等。回转泵适宜输送有润滑性的清洁的液体和液气混合物,特别是粘度大的液体,主要用于油品、食品液体的输送和液压传动方面。
螺杆泵检查:
1、点动螺杆泵电机,试看电机转向是否正确。
2、定期检查螺杆泵轴套的磨损情况,磨损较大后应及时更换。
3、经常调整螺杆泵填料压盖,保证填料室内的滴漏情况正常(以成滴漏出为宜)。
4、检查螺杆泵及管路及结合处有无松动现象。用手转动螺杆泵,试看螺杆泵是否灵活。
5、向螺杆泵轴承体内加入轴承润滑机油,观察油位应在油标的中心线处,润滑油应及时更换或补充。
