It fundamentally overcomes the disadvantage that the existing transmission method can only provide a fixed speed for the mud pump, creating important conditions for realizing the modernization of drilling technology.
Description
The invention belongs to oil drilling machine slurry pump driving mechanism, particularly a kind of gas control variable speed drive that can be used for slurry pump.
Used mud pump for petroleum drilling driver all adopts gear directly to drive slurry pump.This kind of drive can only make slurry pump keep a kind of rotating speed, and the flow and the pressure of its output liquid also remain unchanged.This driving mechanism can not satisfy the requirement of modern conventional drilling, more can not adapt to the drilling engineering construction under special well and the complex situations.The core of modernization drilling technology is the high-pressure jet drilling technology, and the key of this technology is the discharge capacity and the pump pressure of mud.Adopt modernized drilling technology, just must preferably adjust mud pump delivery and pump pressure at any time, adjust hydraulic parameters, just can reach drillng operation not only at a high speed but also safety according to different drill bits, mud, stratum, well depth and down-hole concrete condition.Grand celebration II-130 type rig is the exemplary of prior art.Patent documentation is not found the prior art close with the present invention by retrieval.
Purpose of the present invention just is to overcome the described shortcoming of prior art, and a kind of gas control variable speed drive that can be used for slurry pump is provided.Under the situation that does not change used slurry pump and power source thereof, can make pump obtain 2-8 kind discharge capacity and pump pressure by combination, to satisfy the requirement of modernized drilling technology.This variable speed drive also is applicable to other machinery.
Above-mentioned purpose is realized by following technical proposals:
Each pump group of the present invention is made up of variable transmission mechanism and pneumatic control system two-part.Variable transmission mechanism is made up of two-stage speed changer, high low speed pneumatic clutch, power input and output shaft and belt pulley.Pneumatic control system is made up of gear shift air cock, high low speed air feeding apparatus, high low speed air guide cock tap and air pipe.In the variable transmission mechanism, the friction hub of high speed pneumatic clutch is installed on the power input shaft of one-level speed changer, and its clutch pallet is installed on the pto of dual-range transmission; The pallet of low speed pneumatic clutch is installed on the pto of one-level speed changer, and its friction hub is installed on the power input shaft of dual-range transmission; Belt pulley is installed in the pto of dual-range transmission.The high speed air guide cock tap is installed in dual-range transmission pto outer end, and the low speed air guide cock tap is installed in one-level speed changer pto outer end.Each parts in the pneumatic control system link to each other by air pipe.
The pto of above-mentioned one-level, dual-range transmission is two hollow shafts.One end of axle center hole communicates with the air bag of clutch, and the other end communicates with air guide cock tap.
High low speed air feeding apparatus in the above-mentioned pneumatic control system all is the two-purpose air feeding apparatus, by two air feeding apparatus of gear shift air cock control, makes one of them connection, another shutoff.
When this transmission device of needs provided certain grade of rotating speed, as long as stir the gear shift air cock to corresponding gear, just by disconnected flexible, corresponding pneumatic clutch promptly was inflated extension and closes corresponding air feeding apparatus, driving mechanism just with this rotating speed to the slurry pump transferring power.
The present invention has fundamentally overcome the shortcoming that the direct kind of drive of gear can not change rotating speed, three kinds of discharge capacities of the two drilling pump groups of original three diesel engines can be increased to eight kinds of discharge capacities, and can select discharge capacity and pump pressure under the working state of pump.Used drilling pump utilization ratio can be improved 2.7 times.Created essential condition for developing modern drilling technology.
Accompanying drawing is single pump drive mechanism of the present invention and pneumatic control system principle schematic.
In the accompanying drawing, the 1st, one-level speed changer power input shaft, the 2nd, low speed air guide cock tap, the 3rd, one-level speed changer, the 4th, high speed pneumatic clutch, the 5th, one-level speed changer pto (hollow shaft), the 6th, low speed pneumatic clutch, the 7th, dual-range transmission power input shaft, the 8th, dual-range transmission, the 9th, dual-range transmission pto (hollow shaft), the 10th, belt pulley, the 11st, high speed air guide cock tap, the 12nd, high speed air feeding apparatus, the 13rd, the low speed air feeding apparatus, the 14th, the gear shift air cock, the 15th, air pipe, A are sources of the gas, B is the control air-flow of top gear, and C is the control air-flow of bottom gear.
Details are as follows to the embodiment of the invention in conjunction with the accompanying drawings:
In the variable transmission mechanism, the friction hub of high speed pneumatic clutch 4 is installed on 3 the power input shaft 1 that one-level becomes device, and its clutch pallet is installed on the pto 9 of dual-range transmission 8.The pallet of low speed pneumatic clutch 6 is installed on the pto 5 of one-level speed changer 3, and its friction hub is installed on the power input shaft 7 of dual-range transmission 8.Belt pulley 10 is installed on the pto 9, gives drilling mud pump by belt with transmission of power.
In the pneumatic control system, low speed air guide cock tap 2 is installed in the outer end of axle 5 (hollow shafts), and links to each other with low speed air feeding apparatus 13 air outlets with tracheae.High speed air guide cock tap 11 is installed in the outer end of axle 9 (hollow shafts), and links to each other with high speed air feeding apparatus 12 air outlets with tracheae.The suction port of gear shift air cock 14 two air outlet that links to each other with source of the gas pipeline 15 links to each other with the C inlet with 13 control air-flow B with two air feeding apparatus 12 respectively.Air feeding apparatus 12 all links to each other with air pipe 15 with 13 suction port.
Its working procedure is: power is from axle 1 input, and air pipe 15 is connected the work air source A.When needs top grade rotating speed, gear shift air cock 14 is allocated to " height " gear.This moment, the air cock 14 of leading up to of air current A formed control air-flow B, made air current A pass through high speed air feeding apparatus 12, high speed air guide cock tap 11, hollow shaft 9, entered the air bag of high speed pneumatic clutch 4, its rapid expansion is hung close.At this simultaneously, low speed pneumatic clutch 6 is in disengaged condition.In the case, power is directly passed to axle 9 with same rotating speed after axle 1 input, and belt pulley 10 is to drive the slurry pump running at a high speed.Two speed changers 3 and 8 all are in zero load idling conditions.When needs low grade rotating speed, gear shift air cock 14 is allocated to " low " gear.High speed air feeding apparatus 12 turn-offs at this moment, and air current A is passed through air cock 14 and formed control air-flow C, by low speed air feeding apparatus 13, low speed air guide cock tap 2, hollow shaft 5, enters the air bag of low speed pneumatic clutch 6, and its rapid extension that expands is closed.At this simultaneously, high speed pneumatic clutch 4 is thrown off because of source of the gas is cut off.In the case, power slows down through one-level speed changer 3 after axle 1 input, slows down through dual-range transmission 8 again, gives axle 9 with transmission of power, and belt pulley 10 promptly drives the slurry pump running with low speed.
If adopt three diesel engine two pump group type of belt drive,, can reach eight kinds of discharge capacities by different compound modes.
