Technical field
The utility model relates to a kind of improvement of water pumping gas production pump, the anti-coal dust mining pump of specifically a kind of coal bed gas well use.
Background technique
In the exploitation of coal-seam gas, containing ponding in usual well, need liquid in well to drain, need gas extraction could be discharged to ground smoothly.The mining pump of present coal bed gas well is conventional tubing pump mostly, easily occurs holddown, coal dust buries standing valve phenomenon.
Summary of the invention
It is simple, easy to use that the purpose of this utility model is to provide a kind of structure, can effectively prevent coal dust holddown and standing valve by the problem of burying, the anti-coal dust mining pump that the coal bed gas well increased the service life uses.
In order to reach above object, the technological scheme that the utility model adopts is: the anti-coal dust mining pump that this coal bed gas well uses, comprise lower contact, standing valve, lower travelling valve, long-plunger, short pump barrel, upper connection, rod connector and upper travelling valve, suitable long-plunger is provided with in short pump barrel, the lower end of long-plunger is fixed with lower travelling valve, long-plunger upper end is provided with upper travelling valve, the upper end of upper travelling valve is fixedly connected with sucker rod by rod connector, the lower end of short pump barrel is fixed with box cupling, it is characterized in that: the upper end outer wall of upper box cupling is fixedly connected with upper connection by top outer tube, short pump barrel is positioned at top outer lumen, upper box cupling lower end is connected and fixed by middle part outer tube and lower box cupling, lower travelling valve is positioned at middle part outer lumen, the lower end of lower box cupling is fixedly connected with lower contact by lower outer tubes, lower outer tubes is provided with standing valve in chamber, the lower end of standing valve is fixedly installed on the center hole upper end of lower contact by support tube.
Described upper travelling valve is connected and fixed by the upper end of double thread screw connecting tube and long-plunger.
The beneficial effects of the utility model are: effectively solve coal dust holddown and standing valve that conventional pumps occurs by the problem of burying, extend pump detection period, improve system effectiveness, reduce cost of winning.

Fig. 1 is structure cross-sectional schematic of the present utility model.
In figure: 1, lower contact; 2, support tube; 3, standing valve; 4, lower outer tubes; 5, lower box cupling; 6, lower travelling valve; 7, middle part outer tube; 8, long-plunger; 9, upper box cupling; 10, short pump barrel; 11, top outer tube; 12, upper connection; 13, upper travelling valve; 14, rod connector; 15, double thread screw connecting tube.
Embodiment
The utility model is made with reference to Fig. 1.The anti-coal dust mining pump that this coal bed gas well uses, comprise lower contact 1, standing valve 3, lower travelling valve 6, long-plunger 8, short pump barrel 10, upper connection 12, rod connector 14 and upper travelling valve 13, suitable long-plunger 8 is provided with in short pump barrel 10, the lower end of long-plunger 8 is fixed with lower travelling valve 6, long-plunger 8 upper end is provided with upper travelling valve 13, the upper end of upper travelling valve 13 is fixedly connected with sucker rod by rod connector 14, the lower end of short pump barrel 10 is fixed with box cupling 9, it is characterized in that: the upper end outer wall of upper box cupling 9 is fixedly connected with upper connection 12 by top outer tube 11, short pump barrel 10 is positioned at top outer tube 11 chamber, upper box cupling 9 lower end is connected and fixed by middle part outer tube 7 and lower box cupling 5, lower travelling valve 6 is positioned at outer tube 7 chamber, middle part, the lower end of lower box cupling 5 is fixedly connected with lower contact 1 by lower outer tubes 4, lower outer tubes 4 is provided with standing valve 3 in chamber, the lower end of standing valve 3 is fixedly installed on the center hole upper end of lower contact 1 by support tube 2.
Described upper travelling valve 13 is connected and fixed by the upper end of double thread screw connecting tube 15 with long-plunger 8.
When using the utility model, short pump barrel 10 coordinates with long-plunger 8, forms motive sealing.Short pump barrel 10 geo-stationary, long-plunger 8 moves up and down, and realizes increase and the reduction of volume, for discharge opeing provides power.The utility model itself does not have power plant, drives long-plunger 8 to pump realize draining by the pumping unit on ground by sucker rod.When sucker rod upwards runs, plunger piston assembly (plunger piston assembly comprises lower travelling valve 6, long-plunger 8, double thread screw connecting tube 15, upper travelling valve 13, rod connector 14) is driven upwards to run, upper travelling valve 13, lower travelling valve 6 are closed under the effect of deadweight, space between lower travelling valve 6 and standing valve 3 increases, pressure reduces, standing valve 3 is opened under the pressure of well liquid, and well liquid enters in the chamber of middle part outer tube 7.When sucker rod runs downwards, the space between lower travelling valve 6 and standing valve 3 reduces, pressure increase, and standing valve 3 cuts out under the effect of the pressure, and lower travelling valve 6 and upper travelling valve 13 are opened, and are discharged to the top of upper connection 12 in the chamber of well liquid by middle part outer tube 7.In plunger running, the solid sundries such as the sand grains in well liquid can sink in top outer tube 11 chamber or in lower outer tubes 4 chamber because of Action of Gravity Field, prevent sand grains from entering between short pump barrel 10 and long-plunger 8 and cause clamping stagnation, prevent sand grains from causing inefficacy at standing valve 3 overburden.
