2. Uniform and thin rubber layer is with good anti-deforming
capability in the operation process of the equipment, so screw pump of the
stator with equal wall thickness bears high pressure based on1 single stage
which can reduce pump level and previous excess suitable quantity of stator and
rotor in case of operation under the same operating condition and operating
torque and system efficiency are higher than those of conventional pump to
improve pump usability.

3.等壁厚定子橡胶溶胀、温胀均匀,能较好的保证泵的型线,泵的密封性能好,使用运转时具有良好的力学性能,有利于长时间持续泵的,从而延长泵的使用周期。
3. Rubber of stator with equal wall thickness is with even
swelling and thermal expansion which can well ensure molded lines of the pump.
The pump is with good sealing property as well as good mechanical property at
the moment of use and operation, making for continuous high efficiency of the
pump for a long time to prolong service cycle of the pump.

刀体上设有用于容纳刀具切削的切屑的容屑槽,在容屑槽的前部是刀片的夹持插槽,用于刀片的安装和调整,刀体上设有金属毛刷,随着刀杆的旋转,清理切屑;刀体与刀杆相连接,且为中空,在加工时冷却液可通过中空部分传送。上述的刀具系统还包括调刀套、固定螺丝、调整刻度、固定螺母、固定丝杆,在刀体的外端设有调刀套,调刀套外通过固定螺母将其固定在固定丝杆上;所述的调刀套的另一侧设有调整刻度。上述的刀片安装在调整锥体上。一种等壁厚定子内螺旋成形拉削数控机床的使用方法,主要由调刀,调刀分为对刀、拉削、缩刀、回位、调出刀等步骤组成

由于螺杆泵的衬套由橡胶制成,螺杆与衬套间的相对运动为滚动加滑动,为高粘度、高含砂、高含气的输送创造了有利的条件,加之螺杆泵的运动部件少,过流面积大,油流扰动小,使其能在高粘中工作。
螺杆泵优点:
1 结构简单,价格较低,节省设备采购经费。
2 地面装置结构简单,安装方便,占地面积小。
3 泵效高、节能、管理费用低。泵效可达90%,是现有机械采油设备中效率较高的机种之一。
