单螺杆泵工作时,两端分别作用着液体的吸排压力,因此对螺杆要产生轴向推力。螺杆泵厂家建议对于压差小于10千克力/cm2的小型泵,可以采用止推轴承。此外,还通过主动螺杆的中央油孔将高压油引入各螺杆轴套的底部,从而在螺杆下端产生一个与轴向推力方向相反的平衡推力。
单螺杆泵和其它容积泵一样,莫诺螺杆泵配件,当泵的排出口完全封闭时,泵内的压力就会上升到使泵损坏或使电动机过载的危险程度。所以,螺杆泵厂家建议使用时在泵的吸排口处,就必须设置安全阀。
定转子过早磨损premature wear of fixed rotor定转子过早磨损主要是由于定转子的间隙过小引起的。the premature wear of the fixed rotor is mainly caused by the small gap between the fixed rotor&the rotor.油管与抽油杆柱磨损oil pipe&rod string wear油管与抽油杆柱磨损的原因一是因为井斜抽油杆贴在油管壁上引起的,可以通过加抽油杆扶正器使抽油杆柱居中来减轻或消除,另一个原因是定转子不同心及转子的偏心运动造成的,在定子以上加一节内径较大的回转筒即可避免。tubing&---er rod wear reason is because the deviation of ---er rod attached to the tubing wall caused by heating, pumping rod centralizer make the rod ws= to reduce/eliminate, another reason is caused by the eccentric motion of the rotor&the rotor are not concentric, avoid a day the diameter of rotary cylinder in the stator can be larger than.
d、限位器d, limiting device限位器为一个底部带限位板和流---道的短节,接在定子的尾部,其作用是施工作业时给转子限位以防止下入过头而失去作用和杆柱脱落时防止杆柱掉入井底。the limiting device is a short section with bottom limit plate&distribution channel, which is connected to the tail of the stator. its function is to limit the rotor to the rotor during ctruction1, so as to prevent it from falling into the overhead&lose its function&prevent the rod from falling into the bottom when the rod string falls off.
