Description
Technical field
The utility model relates to the oilfield injection station sampler, specifically the low shearing sampler of a kind of polymer-injecting pump.
Background technique
Because being subject to shear, polymer solution degrades, cause reduced viscosity, therefore a kind of device of necessary employing can be as far as possible close to taking out polymer-like liquid under the situation of pump discharge pipeline internal environment, polymer-injecting pump mother liquor viscosity shearing rate is a key node index of polymer injector system, needs per month every pump is carried out to sampling and measuring.The sample collector used at present is the low shearing sampler of DQY-160-600 type, this low shearing sampler cost is high, more than 6000 yuan every, in the high pressure spot sampling process, pressure balance cover and the valve rod of sample collector are fragile, and be 77 days average life, after damage, be difficult for again repairing, bring difficulty to normal sample examination, injecting data accurately can't be provided, make the poly-index of notes of annotating poly-station not reach standard-required.
Summary of the invention
The purpose of this utility model is exactly in view of the foregoing defects the prior art has, provides a kind of polymer-injecting pump to hang down shearing sampler.
The technical solution of the utility model comprises: sampling gate, housing, piston, big sealing ring, guide rod, end cap, sealing gasket, small sealing ring, pressure balance gate, high-pressure rubber pipe, joint.The housing of the low shearing sampler of its polymer-injecting pump is cylindrical shape and trumpet-shaped superimposed body, left end is provided with sampling gate, piston is equipped with in inside, piston is connecting guide rod, guide rod is through the center hole of the end cap be threaded with the housing right-hand member, the housing right-hand member is circumferentially with the pressure balance gate, is connecting successively high-pressure rubber pipe, joint on the pressure balance gate.
Piston in the low shearing sampler of above-mentioned polymer-injecting pump is that cylindrical body and cone are formed by stacking, and is circumferentially with big sealing ring, and center is provided with blind screw hole.
The center hole of the end cap in the low shearing sampler of above-mentioned polymer-injecting pump is provided with small sealing ring.
Be provided with sealing gasket between housing right-hand member in the low shearing sampler of above-mentioned polymer-injecting pump and end cap.
The beneficial effects of the utility model are: modern design, easily manufacture, and easy to operate, shearing force is little, long service life.Can take out mother liquor sample accurately, in order to provide, chemically examine accurately injecting data, make the poly-index of notes of annotating poly-station reach standard-required.
The accompanying drawing explanation

In accompanying drawing, 1. sampling gate, 2. housing, 3. piston, 4. big sealing ring, 5. guide rod, 6. end cap, 7. sealing gasket, 8. small sealing ring, 9. pressure balance gate, 10. high-pressure rubber pipe 11. joints; A. hyperbaric chamber, the B. low-pressure cavity.
Embodiment
Below in conjunction with accompanying drawing, the utility model will be further described:
The low shearing sampler of polymer-injecting pump is comprised of sampling gate 1, housing 2, piston 3, big sealing ring 4, guide rod 5, end cap 6, sealing gasket 7, small sealing ring 8, pressure balance gate 9, high-pressure rubber pipe 10, joint 11.The housing 2 left end sampling gates 1 of the low shearing sampler of its polymer-injecting pump are connected with the outlet discharge opeing gate of polymer-injecting pump, the guide rod 5 of internal piston 3 is through the center hole of the end cap 6 be threaded with housing 2 right-hand members, connecting successively high-pressure rubber pipe 10, joint 11 on housing 2 right-hand member pressure balance gates 9, joint 11 is connected with the import emptying gate of polymer-injecting pump.
Operating method
During sampling, open the outlet discharge opeing gate of polymer-injecting pump, import emptying gate, the increased pressure in hyperbaric chamber A now, after hyperbaric chamber A and low-pressure cavity B pressure balance, slightly open pressure balance gate 9, medium in low-pressure cavity B flows to the polymer-injecting pump import by balance gate 9 and high pressure hose 10, now, control the aperture of balance gate 9 well, piston 3 is slowly moved to right, the liquid that samples enters hyperbaric chamber A, while in hyperbaric chamber A, being full of got polymeric solution, close outlet discharge opeing gate and the pressure balance gate 9 of polymer-injecting pump, open sampling gate 1 pressure release, slightly open pressure balance gate 9, now the pressure of polymer-injecting pump low-pressure cavity B is greater than the pressure of hyperbaric chamber A, piston 3 slowly moves to left under the effect of pressure, sample liquid in hyperbaric chamber A is taken out, to reach the low purpose of shearing sampling.
