Abstract
The utility model discloses a cycling device for normal circulation and reverse circulation of a drilling machine by two pumps, which comprises a power output device, a water injection pump, and a water pump. Through the power output device, motive power of a prime mover can simultaneously drive the water injection pump or the water pump to rotate; according to different geological conditions, drilling machines are caused to not only can realize drilling operation of normal circulation, but also can realize the drilling operation of reverse circulation; drilling efficiency is high, and a machine is provided with two pumps. The utility model not only can save energy, but also can obtain farthest simplification for mechanical driving. A combined type integral structure is adopted, and operation, disassembly and assembly, and transportation are convenient.
Description
The utility model relates to a kind of and the supporting positive and negative circulating device of a machine two pumps of drilling machinery.
At present, the known drilling machinery in the world is all supporting a kind of water filling device or water plug of finishing bore operation, at general stratum drilling efficiency height, become the well quality good, but then drilling efficiency is on the low side for other stratum, has directly influenced economic benefit.
The purpose of this utility model is to provide a kind of positive and negative circulating device of a machine two pumps that is used for rig, at different formation conditions, both can realize that direct circulation crept into operation, can realize the reverse circulation drilling operation again, thereby improves drilling efficiency.
Be used to realize that the positive and negative circulating device of the utility model above-mentioned purpose comprises a cover power take-off and one group of notes, suction pump.
A described cover power output output device comprises a power input shaft, two power output shafts and set of gears transmission device, and described gear drive is used for the power of power input shaft is reached power output shaft.
Described two power output shafts comprise second of first of power output and power output, the coaxial setting of diaxon and vertical with power input shaft, first of power output is provided with the bevel gear of often closing with power input shaft inner end bevel gear and with the embedded clutch of this rotation, so as with the power of power shaft from or not from reaching power output shaft.Second of power output is adopted and is realized power output in the same way.
According to the utility model, this power take-off preferably includes a casing, so that power input shaft, power output shaft are placed on the casing with rotating form.
Described one group of water filling, suction pump comprise a water injecting pump and suction pump.Described water injecting pump can be with liquid along connecting tube through the water filling in wellhole of suction pump, sebific duct, drilling system, both operation was crept in direct circulation, can discharge the air in suction pump and the pipeline simultaneously again; Described suction pump can be when water injecting pump quits work, sucking-off mud stone quarrel in the wellhole, both reverse circulation drilling operations.
Described water injecting pump comprises water inlet pipe that links with water inlet and the cross over pipe that links with delivery port, and also designing on the described cross over pipe has the watered cup and the gate valve of discharging air in the water injecting pump.The other end of described cross over pipe and suction pump steam vent link, and the place, deslagging hole of suction pump is provided with control and is just realizing or reverse circulation drilling operation gate valve that the water inlet of suction pump and the drilling system of drilling machinery link with sebific duct.
The positive and negative circulating device of a machine two pumps that is used for rig of the present utility model compared with prior art, because design has single prime mover that the water injecting pump and the suction pump of power are provided, therefore, drilling machinery can both can realize that direct circulation crept into operation at different geological conditionss, can realize the reverse circulation drilling operation again, the drilling efficiency height, machine driving is farthest simplified, and has saved the energy.It also has advantage of simple structure, adopts the combined integrate structure, operation, dismounting, convenient transportation.
Below in conjunction with description of drawings preferred embodiment of the present utility model.
Accompanying drawing 1 is the structural representation that the utility model is used for the positive and negative circulating device of a machine two pumps of rig.
Shown in the accompanying drawing 1: water injecting pump 23, suction pump 12 and power take-off are installed on the same frame, and water injecting pump 23 and suction pump 12 pass through the shaft coupling transferring power with first 20 of power output and power output shaft 11 respectively.
Open gate valve 1, closing gate valve 15, water filling in funnel 2, discharge the air in water injecting pump 23 and the water inlet pipe 22, closing gate valve 1, start prime mover 4, power is reached the friction of power input shaft 7 ends from containing device 6 by the flexible body device, power input shaft 7 is in company with friction clutch 6 rotations, driving is fixed in the travelling gear 8 on the power input shaft 7, travelling gear 21 and travelling gear 8 formative gear pairs on power is exported first 20, make gear 21 idle running on power is exported first 20, manipulation combines with the tooth embedding of travelling gear 21 ends in company with first 20 embedded clutch 19 that rotates of power output, embedded clutch 19 changes together with travelling gear 21, drive water injecting pump 23 work by shaft coupling 24, liquid is along water inlet pipe 22, water injecting pump 23, connecting tube 3, suction pump 12, sebific duct 13 is until the drilling system 14 of drilling machinery, and operation is crept in the realization direct circulation.Handle embedded clutch 19, it is separated with the tooth embedding of travelling gear 21, power output stops operating for first 20, and water injecting pump 23 stops to supply water.Simultaneously, open gate valve 15, handle embedded clutch 9, power output realizes power output for second 11 in an identical manner, make suction pump 12 work, mud stone is starched along drilling system 14, sebific duct 13, is discharged from the deslagging aperture gate valve 15 of suction pump 12, realizes the reverse circulation drilling operation.
