Its function is to transfer power and write the stator to form a seal cavity.Ｃ、回转筒C, rotary barrel回转筒也就是一根内径较大的油管或空心定子筒，接在定子的上部以给转子和抽油杆杆柱以较大的回旋空间，防止转子和抽油杆因偏心运动磨擦磨损油管。A rotary cylinder is also an oil tube or hollow stator barrel with larger inner diameter. It is connected to the upper part of the stator to provide larger swirl space for the rotor and sucker rod string, so as to pvent the rotor and sucker rod from attrition wear due to eccentric wear.

Ｆ、抽油杆F, sucker rod所使用的抽油杆是常用的普通抽油杆、空心抽油杆和连续抽油杆，可根据油井确定。The sucker rod used is commonly used as a common 1sucker rod, hollow sucker rod and continuous sucker rod, which can be determined according to the oil well.Ｇ、定子扶正器G, stator centralizer定子扶正器为有一定弹性的笼形装罩，每一对由两半构成，中间大、两端小。作用是使定子居中和减小定子的摆动。The stator centralizer is a cage shaped cover with a certain elasticity. Each pair is made up of two halves, large in the middle and small at both ends. The function is to make the stator middle and reduce the stator wobble.Ｈ、锚定装置H, anchoring device对于没有封隔器的井和泵挂深度浅的井，用于固定定子、消除摆动和防止定子脱扣。采用普通的锚定装置即可。For wells without packers and shallow wells with deep pumps, it is used to fix the stator, eliminate the swinging and pvent the tripping of the stator. A common anchoring device can be used.

污泥输送泵多用于排放粘度较高的输送机械。利用叶轮的水利设计减少堵塞现象;轴和油室的密封紧密;安装方便减少了操作的繁琐，并且使用方便;易于维护。

污泥输送泵不仅在生活中使用方便，使用寿命也长。在规定条件下，故障运行时间不小于10000h，整机使用寿命不小于20年。

污泥输送泵的发展是因为其自身的技术特点及结构的合理，给我们带来很大程度的方便。

G型单螺杆泵型号在加热炉燃烧系统中的应用 　　目前,有些中小型钢铁厂和其它冶金加工厂在没有气体燃料(如煤气)的条件下,仍在使用液体燃料。而液体燃料为广泛采用的是重油。比如加热炉燃烧系统在重油的输送及喷燃过程中,选择合适的泵机组对炉子的正常工作很重要。由于重油的正常工作粘度一般都比较高(80 ℃时在50×102-6m2/s以上) ,而且随着温度的变化,其粘度的变化比较大。这就要求我们应该选择合适的泵种以适应这些介质的输送,使之稳定而无故障地运行。尤其是重油的喷燃,泵机组输送压力的恒定很重要。根据调查发现,目前采用外啮合齿轮泵(称齿轮泵)的用户仍居多。其实在这些系统中如果采用G型单螺杆泵则是有更多优点。
