lang="EN-US">,</span><span style="color:#666666;">最后挤出泵体。螺杆泵是一种新型的输送液体的机械</span><span style="color:#666666;" lang="EN-US">,</span><span style="color:#666666;">具有结构简单、工作安全可靠、使用维修方便、出液连续均匀、压力稳定等优点。螺杆泵的工作原理是:螺杆泵工作时,液体被吸入后就进入螺纹与泵壳所围的密封空间,当主动螺杆旋转时,螺杆泵密封容积在螺牙</span><span style="color:#666666;">的挤压下提高螺杆泵压力,并沿轴向移动。由于螺杆是等速旋转,所以液体出流流量也是均匀的?/span><span lang="EN-US"><?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office"

lang="EN-US">:</span>因其有可变量输送、自吸能力强、可逆转、能输送含固体颗粒的液体等特点,在污水处理厂中,广泛地被使用在输送水、湿污泥和絮凝剂药液方面。螺杆泵选用应遵循经济、合理的原则。如果在设计选型方面考虑不周,会给以后的使用、管理、维修带来麻烦,所以选用一台符合生产实际需要的螺杆泵既能保证生产顺利进行,又可降低修理成本?span

lang="EN-US"><br /> </span><span style="font-family:宋体;color:#666666;">国内生产的大都仿制进口产品,产品质量良莠不齐,在选用国内生产的产品时,在考虑其性价比的时候,选用低转速,长导程,传动量部件材质优良,额定寿命长的产品。上海上久泵业生产的螺杆泵系列产品是您最好的选择<span style="color:#666666;"

</span>螺杆泵的流量与转速成线性关系,相对于低转速的螺杆泵,高转速的螺杆泵虽能增加了流量和扬程,但功率明显增大,高转速加速了转子与定子间的磨耗,必定使螺杆泵过早失效,而且高转速螺杆泵的定转子长度很短,极易磨损,因而缩短了螺杆泵的使用寿命?/span><span lang="EN-US"><br /> </span><span style="font-family:宋体;color:#666666;">通过减速机构或无级调速机构来降低转速,使其转速保持在每分三百转以下较为合理的范围内,与高速运转的螺杆泵相比,使用寿命能延长几倍?span lang="EN-US"><o:p></o:p></span></span></span></p> <p

style="color:#666666;" lang="EN-US">:<br /> </span>湿污泥中混入的固体杂物会对螺杆泵的橡胶材质定子造成损坏,所以确保杂物不进入泵的腔体是很重要的,很多污水厂在泵前加装了粉碎机,也有的安装格栅装置或滤网,阻挡杂物进入螺杆泵,对于格栅应及时清捞以免造成堵塞?span

style="font-family:宋体;color:#666666;"><span style="color:#666666;" lang="EN-US">:<br /> </span>螺杆泵决不允许在断料的情形下运转,一经发生,橡胶定子由于干磨擦,瞬间产生高温而烧坏,所以,粉碎机完好,格栅畅通是螺杆泵正常运转的必要条件之一,为此,有些螺杆泵还在泵身上安装了断料停机装置,当发生断料时,由于螺杆泵其有自吸功能的特性,腔体内会产生真空,真空装置会使螺杆泵停止运转?span lang="EN-US"><o:p></o:p></span></span></span></p> <p style="line-height:15pt;background:white;"><span style="color:black;font-size:9pt;"><span style="font-family:宋体;color:#666666;">五、保持恒定的出口压力</span><span style="font-family:宋体;color:#666666;"><span style="color:#666666;" lang="EN-US">:<br /> </span>螺杆泵是一种容积式回转泵,当出口端受阻以后,压力会逐渐升高,以至于超过预定的压力值。此时电机负荷急剧增加。传动机械相关零件的负载也会超出设计值,严重时会发生电机烧毁、传动零件断裂。为了避免螺杆泵损坏,一般会在螺杆泵出口处安装旁通溢流阀,用以稳定出口压力,保持泵的正常运转?span
