Abstract
The utility model provides an oil-gas mixed transmission pump using automatic fluid infusion. An automatic fluid infusion tank is arranged on a base; the automatic fluid infusion tank and a pump are integrated; an inlet of the automatic fluid infusion tank is connected with a pump outlet; an outlet of the automatic fluid infusion tank is connected with a pump inlet; an automatic liquid filling pressure control valve and an automatic fluid infusion valve are respectively arranged at the inlet and outlet of the automatic liquid infusion tank; a flow monitoring meter is arranged at the pump inlet; and an automatic exhaustion valve is arranged on the top of the automatic fluid infusion tank. The oil-gas mixed transmission pump has a simple overall structure, is convenient to mount, saves the investment, can automatically realize fluid filling and fluid infusion, ensures that continuous flow is formed in the pump, changes the condition that the slug flow occurs frequently in the traditional oil-gas mixed transmission pump, and conveniently realizes oil-gas mixed transmission.
Description
Technical field
The utility model relates to oil-conveying device, especially relates to the oil-gas mixed delivery pump that the oil field oil transportation is used.
Background technique
Existing oil-gas mixed delivery pump is comprised of base 16, motor 9, transmission case 7, speed reducer 8, screw pump assembly 10 and other annexes.Screw pump assembly 10 links to each other with transmission case 7, and is connected to form an integral body by speed reducer 8 and motor 9, jointly is fixed on the base 16 that is welded by channel-section steel and angle steel.Such oil-gas mixed delivery pump has three shortcomings: the one, and slug flow appears in oil-gas mixed delivery pump easily when oil and gas multiphase flow; The 2nd, when slug flow occurring, must shut down and could continue after the exhaust to carry; The 3rd, slug flow can make bad seals after occurring, rotor, stator wear aggravation, and the shortening in working life of whole pump has increased maintenance cost.
Summary of the invention
The purpose of this utility model is that a kind of oil-gas mixed delivery pump that adopts automatic liquid supply will be provided, and under the prerequisite of the use function that guarantees oil-gas mixed delivery pump and effect, has the advantages that the replacing of installing is convenient, the installation time is short, be convenient to keep in repair exchange.
The technical solution of the utility model is: a kind of oil-gas mixed delivery pump that adopts automatic liquid supply, it is characterized in that the automatic makeup flow container is installed on the base, form an integral body with pump, the import of automatic makeup flow container links to each other with pump discharge, the outlet of automatic makeup flow container links to each other with pump inlet, import and export at the automatic makeup flow container arrange respectively automatic liquid feeding pressure controlled valve and automatic liquid supply valve, and in pump inlet flow monitoring instrument are set, and are provided with automatic control pressure vent in the automatic liquid supply tank top.
Wherein be provided with flow monitoring instrument and reach the flow monitoring line in pump inlet, between pump inlet and automatic liquid supply valve, be provided with pump inlet fluid infusion pipeline, between automatic control pressure vent and pump inlet, be provided with gas and advance the pump inlet pipeline, between automatic makeup flow container and automatic liquid feeding pressure controlled valve, be provided with sealant supplement cylinder topping up pipeline.
The technical solution of the utility model is under the prerequisite of the use function that guarantees oil-gas mixed delivery pump and effect, install the automatic makeup flow container additional at pump, and in pump inlet flow monitoring instrument is set, feed liquor situation according to pump inlet, realization is eliminated the slug flow in the pump housing from trend pump inlet fluid infusion, makes it form Continuous Flow, reach the purpose of oil and gas multiphase flow, improve the operating conditions of existing mixing pump.Described automatic makeup flow container, automatic control pressure vent, flow monitoring instrument, automatic liquid feeding pressure controlled valve, automatic liquid supply valve consist of the automatic liquid supply system, are the vitals of automatic liquid supply oil-gas mixed delivery pump.
The utility model is applicable to various oil-gas mixed delivery pumps, and except increasing the automatic liquid supply system, all the other structures of oil-gas mixed delivery pump remain unchanged.Installation, maintenance and replacing are convenient, greatly reduce maintenance, change difficulty, have reduced installation, maintenance, renewal cost, have good value for applications.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Below with reference to accompanying drawing the utility model is described further.
As shown in Figure 1, a kind of oil-gas mixed delivery pump that adopts automatic liquid supply, automatic makeup flow container 13 is fixed on the base 16, form an integral body with pump, the import of automatic makeup flow container 13 links to each other with pump discharge 1, the outlet of automatic makeup flow container 13 links to each other with pump inlet 6, import and export at automatic makeup flow container 13 arrange respectively automatic liquid feeding pressure controlled valve 15 and automatic liquid supply valve 12, between automatic makeup flow container 13 and automatic liquid feeding pressure controlled valve 15, be provided with sealant supplement cylinder topping up pipeline 14, between pump inlet 6 and automatic liquid supply valve 12, be provided with pump inlet fluid infusion pipeline 11.
Automatic makeup flow container 13 is fixed on the base 16, realize that by automatic liquid feeding pressure controlled valve 15 pump discharge 1 is to automatic makeup flow container 13 automatic liquid feedings, automatic makeup flow container 13 is monitored according to flow monitoring instrument 3 and 5 pairs of import fluid floies of flow monitoring line of pump inlet 6, and by automatic liquid supply valve 12 and pump inlet fluid infusion pipeline 11 to pump inlet 6 automatic liquid supplies.When tank body pressure reaches a certain setting value, automatic control pressure vent 2 that can be by the top is gentle to be advanced pump inlet pipeline 4 unnecessary gas is discharged to pump inlet 6, realizes automatically adjusting the pressure of sealant supplement cylinder 13, reaches from trend pump inlet 6 fluid infusion, make to form Continuous Flow in the pump, realize the purpose of oil and gas multiphase flow.
Installation and application: screw pump assembly 10, transmission case 7 form one with retarder 8 and motor 9 etc., be installed on the base 16, the automatic liquid supply system also is installed on the base, finish the assembly working of the oil-gas mixed delivery pump of automatic liquid supply, the scene of the oil-gas mixed delivery pump of whole automatic liquid supply is installed with oil-gas mixed delivery pump identical.In use, utilize the automatic liquid supply system to carry out fluid infusion to pump inlet 6.During maintenance automatic liquid supply system, very convenient.
