Abstract
The driving structure of a hydraulic motor drive well drilling pump is suitable for the well drilling pump driven by the hydraulic motor and belongs to the technical field of petroleum drilling and exaction equipment and machine manufacturing. The utility model comprises an engine, a transfer case, a hydraulic pump, a hydraulic motor and a well drilling pump. One transfer case is positioned between the engine and the hydraulic pump; two hydraulic motors are respectively positioned at both ends of the crankshaft of the well drilling pump, and the output ends of the hydraulic pump are connected with the hydraulic motor positioned at both ends of the crankshaft of the well drilling pump. The utility model provides one drive structure of the hydraulic motor drive well drilling pump that adopts the hydraulic motor drive and can realize stepless speed changing, solves such problems as huge cubic connection equipment of hydraulic couplings, complex structure and large work load of moving and arranging equipments exist in hydraulic coupling techniques. The hydraulic motor drive well drilling pump adopted by the utility model can realize the stepless speed changing in a wide range and prevent overload.
Description
Technical field: a kind of drive mechanism of fluid motor-driven borehole pump, be used for the borehole pump transmission of oil and gas well drilling machinery, be specially adapted to the borehole pump of fluid motor-driven, belong to the oil drilling and extracting equipment machinery manufacturing technology field.
Background technology: the circulation of mud realizes by borehole pump, mud directly has influence on the quality of drilling engineering, and existing borehole pump has two kinds of kinds of drive, first kind is to utilize motor, drives the borehole pump main shaft and promotes piston output mud by fluid-flywheel clutch; Second kind be that motor drives generator, then by power transmission and transformation device drive motor, again by deceleration device, drives the borehole pump main shaft and promote piston output mud.These two kinds of kinds of drive are continued to use for many years, and the main problem that exists is: drive mechanism complexity, bulky, manufacturing cost height, maintenance cost are big.
Summary of the invention: the purpose of this utility model is at the deficiencies in the prior art, adopts the fluid motor-driven borehole pump, can realize infinite variable speed structure, designs a kind of fluid motor-driven borehole pump drive mechanism.
The utility model is achieved in that the utility model comprises motor, transfer case, hydraulic pump, hydraulic motor and borehole pump.Be provided with a transfer case between motor and hydraulic pump, at the two ends of borehole pump bent axle a hydraulic motor be set respectively, the hydraulic pressure delivery side of pump connects the hydraulic motor that is arranged on the borehole pump crankshaft two end respectively by high-voltage tube; During work, the power that is produced by motor drives hydraulic pump generation hydraulic coupling by transfer case, drives hydraulic motor again, by fluid motor-driven borehole pump bent axle, connecting rod, promotion piston output mud.
Advantage of the present utility model is: the utility model adopts hydraulic motor, in transmission system, reduce gear reduction box, belt or sprocket wheel, cancelled the devices such as gear driving pair between main shaft and the bent axle, therefore dwindled the space, it is little to have a volume, the characteristics that quality is little; Because what adopt is fluid motor-driven borehole pump bent axle, can realize infinitely variable speeds in wide range, prevent overload easily.
Description of drawings:
Fig. 1 is a configuration structure schematic diagram of the present utility model.
The specific embodiment: provide embodiment of the present utility model below in conjunction with accompanying drawing: the utility model is achieved in that the utility model comprises motor 1, transfer case 2, hydraulic pump 3, hydraulic motor 4 and borehole pump 5; A transfer case 2 is set between motor 1 and hydraulic pump 3, at the two ends of borehole pump 5 bent axles a hydraulic motor 4 is set respectively, the output of hydraulic pump 3 connects the hydraulic motor 4 that is arranged on borehole pump 5 crankshaft two ends respectively by high pressure line, hydraulic motor 4 is driven by the high pressure liquid stream that hydraulic pump 3 produces, drive borehole pump 5 crankshaft rotating, and promote piston output mud.During operation, elder generation's ato unit 1, the power input transfer case 2 of motor 1, transfer case 2 outputting powers drive hydraulic pump 3 and produce hydraulic coupling then, driving the borehole pump that surpasses more than, when needs are more high-power, can connect plural hydraulic pump 3 by transfer case 2, by the high-voltage transmission pipeline high pressure liquid stream is delivered to hydraulic motor 4 by the high pressure liquid stream that hydraulic pump 3 produces, owing to be respectively arranged with hydraulic motor 4 at the two ends of borehole pump 5 bent axles, when therefore the high pressure liquid stream that produces when hydraulic pump 3 arrives hydraulic motor, hydraulic motor will begin rotation, and the crankshaft rotating of driving borehole pump 5, the rotation of borehole pump 5 bent axles promotes piston and back and forth moves, and reaches the purpose of slurry transportation to the down-hole.
