Further improvement:
Described draft tube is rectangle, and bore is outer little interior large shape.
Further improvement:
Be provided with the first sealing gasket between coarse particle gatherer and separator body, between filter membrane squeeze and separator body, be provided with the second sealing gasket.
The utility model adopts technique scheme, and the structure of two air pump and two air chamber makes flow more stable, under can overcoming the impact of ore deposit downhole oil, water, mist; The design of filter membrane clip well can fix filter membrane, and can not damage filter membrane; The setting of woven wire can prevent filter membrane fold or break in employing process; Draft tube is rectangle, and bore is outer little interior large shape, can maintain the air velocity of air intake opening, can prevent the mud contamination filter membrane that sampled point splashes, and improves sampling precision; The setting of the first sealing gasket and the second sealing gasket can increase the sealing property of sampling head.
Be described further below in conjunction with accompanying drawing the technical solution of the utility model.
