The twin-engine power device comprises an engine with smaller power and the engine with larger power; a main pump and a pilot pump are arranged on the engine with the smaller power, the main pump supplies oil to a main valve through a one-way hydraulic valve, and the pilot pump supplies the oil to a pilot hydraulic system; and the main pump and an auxiliary pump are arranged on the engine with the larger power, the main pump supplies the oil to the main valve through the one-way hydraulic valve, and the auxiliary pump supplies the oil to an auxiliary hydraulic system. The twin-engine power device has the advantages of reducing the cost of the engines and saving the energy.
Description
Technical field
The utility model relates to the dynamical system of rotary drilling rig, specifically is a kind of large-scale rotary drilling rig double engine power unit.Be specially adapted to large-scale rotary drilling rig.
Background technology
Because rotary drilling rig self characteristics flexibly and fast, and the restriction of rotary drilling rig operating environment and condition, in the selection of dynamical system with use and all adopt diesel engine as power source, drive hydraulic pump by diesel engine energy is transformed and transmits, guarantees whole machinery normal operation.
At present, the dynamical system on the domestic large-scale rotary drilling rig all is to adopt high-power monomotor to drive the conversion that several parallel connections or pumps in series mode realize energy.A motor drives the mode of many pumps, though succinct convenient, but high-power engine is owing to being that a motor provides power, so can not well realize controlling energy-conservation, and now rotary drilling rig mostly uses is imported engine, its import price costliness.
Summary of the invention
For solving the problems of the technologies described above, the utility model provides a kind of large-scale rotary drilling rig double engine power unit, replaces a powerful motor with two low power motors, reduces and starts the cost of motivation, energy conservation.
The utility model overcomes the above problems the technical scheme that is adopted: a kind of large-scale rotary drilling rig double engine power unit is characterized in that double engine power unit has motor and a more powerful motor of a smaller power; A main pump I and a pioneer pump of connecting with main pump are installed on the flywheel of the motor of smaller power, and the oil-out of main pump I is connected by the oil-in of oil pipe with the main valve I of rotary drilling rig hydraulic system; A main pump II and an auxilliary pump of connecting with main pump are installed on the flywheel of more powerful motor, and the oil-out of main pump II is connected by the oil-in of oil pipe with the main valve II of rotary drilling rig hydraulic system; To the oil circuit of main valve I, to the oil circuit of main valve II, respectively be connected with a unidirectional hydraulic valve at main pump I with main pump II.Main pump I gives a main valve I fuel feeding through a unidirectional hydraulic valve, and pioneer pump is connected to guide's hydraulic system fuel feeding with guide's hydraulic system of rotary drilling rig by pipeline.Main pump II gives a main valve II fuel feeding through a unidirectional hydraulic valve, and auxilliary pump is connected to auxilliary hydraulic system fuel feeding with the auxilliary hydraulic system of rotary drilling rig by pipeline.
Owing to adopted technique scheme, drive two cover hydraulic pump systems by two motors, provide energy to equipment, utilize valve regulation control.When requiring power not to be very big, can reduce the rotating speed of a motor, allow a motor full speed operation, assurance equipment can operate as normal: require powerful the time two motors together high speed operation guarantee operate as normal, with this just can control separately mode, utilize the work of single motor high power work when being implemented in little load, twin-engined work in the time of powerful are saved the energy with the reasonable utilization that arrives power.
The beneficial effects of the utility model are: two motors can work alone, and all are with a main pump separately, can provide power to main valve.During the power that under the different capacity state, requires to provide different, can reduce some motors that does not need high-power rotation, like this can energy conservation, the protection environment.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Accompanying drawing is the utility model principle assumption diagram.
Among the figure: 1, smaller power motor, 2, than high-power engine, 6, main pump I, 4, auxilliary pump, 5, main valve II, 3, main pump II, 7, pioneer pump, 8, main valve I, 9, unidirectional hydraulic valve.
The specific embodiment
As shown in drawings, large-scale rotary drilling rig double engine power unit has motor 1 and more powerful motor 2 of a smaller power; A main pump I6 and a pioneer pump of connecting with main pump 7 are installed on the flywheel of the motor 1 of smaller power, and the oil-out of main pump I6 is connected by the oil-in of oil pipe with the main valve I8 of rotary drilling rig hydraulic system; A main pump II3 and an auxilliary pump 4 of connecting with main pump are installed on the flywheel of more powerful motor, and the oil-out of main pump II3 is connected by the oil-in of oil pipe with the main valve II5 of rotary drilling rig hydraulic system; Respectively be connected with a unidirectional hydraulic valve 9 with main pump II3 at main pump I6 to the oil circuit of main valve II5 to the oil circuit of main valve I8, pioneer pump 7 is connected to guide's hydraulic system fuel feeding with guide's hydraulic system of rotary drilling rig by pipeline; Auxilliary pump 4 is connected to auxilliary hydraulic system fuel feeding with the auxilliary hydraulic system of rotary drilling rig by pipeline.
When ato unit 1, drive main pump I6 running, high-pressure and hydraulic oil from the pressure oil of main pump I6 outlet to main valve I8 oil-in, through control to main valve I8, high-pressure and hydraulic oil arrives executive component from main valve I8 corresponding work hydraulic fluid port A, B, the work of driving executive component, the outlet high-pressure and hydraulic oil of pioneer pump 7 arrives guide's hydraulic system, power is provided for guide's hydraulic system.Realize this moment is the part critical element and work guide's hydraulic system.
When ato unit 2, drive main pump II3 running, high-pressure and hydraulic oil from the pressure oil of main pump II3 outlet to main valve II5 oil inlet P, through control to main valve II5, high-pressure and hydraulic oil arrives executive component from main valve II5 corresponding work hydraulic fluid port A, B, the work of driving executive component, the outlet high-pressure and hydraulic oil of auxilliary pump 4 arrives auxilliary hydraulic system, power is provided for auxilliary system.What realized this moment is the work of part critical element and auxilliary system.
