按螺杆泵内螺杆的数目划分:
这种分类是按泵的表面特征来识别,在应用领域方面有其特色,间接反映了泵的重要特点,因此成了一种最重要的
分类方法。螺杆泵通常分为单螺杆泵、双螺杆泵、三螺杆泵和五螺杆泵四类。目前生产和应用得很少的四螺杆泵一
般都不单独列作一个门类,而是按照它的螺杆螺旋面的型线类型,附在与其螺旋面型相同的三螺杆泵这一类,作为
三螺杆泵的衍生产品。
机械密封是靠一对或几对垂直于轴作相对滑动的端面在流体压力和补偿机构的弹力或磁力作用下保持接合并配以辅助密封而达到的阻漏的轴封装置。
机械密封性能可靠,泄漏量小,使用寿命长,功耗低,无需经常维修,且能适应于生产过程自动化和高温、低温、高压、真空、高速以及各种强腐蚀性
介质、含固体颗粒介质等苛刻工况的密封要求。
密封的主要作用:
1、阻止液体、气体等工作介质以及润滑剂泄露;
2、防止灰尘、水分进入润滑部位
密封的选择:
使用时,应根据压力、转速、工作温度等工作条件,选择经济、合理的密封类型和结构。
密封件大部分都有相应的标准和规格,应尽量选用标准件。
根据被密封表面是否有相对运动,密封分为静密封和动密封。
