The sleeve pipe 20 that holds this jackshaft 14, this sleeve pipe 20 is fixed to the input end 21 of stator 8 with sealing means, and sleeve pipe 20 has a lateral opening 24, and it has formed the inlet (arrow 25) by the liquid of pumping unit 1 transmission; And
Liquid delivery tube or pipeline 22 are fixed on the output terminal 23 of stator 8 with sealing means.
As shown in Figure 3, the input end 21 of stator 8 has neck 28, and this neck 28 has formed and stator external surface 30 corresponding first shoulders 29.As shown in Figure 4, the end pipe fitting 26 of sleeve pipe 20 and neck 28 engagements.
And the input end 21 of stator 8 provides the groove 31 that has formed corresponding to the second and the 3rd shoulder 27,32 of stator outer surface 30.
According to the present invention, groove 31 has two embossment shape stationary parts 33, is suitable for anchor hole 34 cooperative cooperatings by an anchoring element 36 and two complementary shape, so that prevent that stator 8 is with respect to 38 rotations of the fixed support shown in Fig. 1 and 2.
By example, fixed support 38 is made of the ground at pumping unit 1 place, and perhaps the planar surface by any other carrying pumping unit 1 constitutes.
Each embossment shape stationary part 33 comprises an indentation portion or a projection.It has formed an impression.
In first mode of execution of the present invention shown in Fig. 3, each embossment shape stationary part 33 is made up of flat 40, and this flat 40 extends along the angle part of an inclination of stator, and this range of tilt angles is 5 °-40 °.
Preferably, embossment shape stationary part 33 is positioned on the cyclic position of qualification in advance of stator 8, be secured on the stator 8 and on the fixed support 38 time when anchoring element 36 like this, first module 39 extend vertically and the longitudinal axis of first module preferably vertical substantially, as shown in Figure 2.
Advantageously, the cyclic position of this stator 8 has improved the suction capactity of pump 2.
Advantageously, the cyclic position of this stator 8 has reduced bubble quantity and bubble.
Advantageously, the cyclic position of this stator 8 has improved efficient.
Land productivity is arranged, and the cyclic position of this stator 8 has also improved the cleanability of pump 2.
