Detailed description of the invention
With reference to Fig. 1, a kind of LNG power fracturing unit truck, comprise car body 1, frame beam after described car body 1 is positioned at driver's cabin is installed with platform 4, described platform 4 is fixed with LNG gas bottle device assembly 2, radiator 5, gas engine 6, fluid torque-converter 7, power transmission shaft 8, fracturing pump 9, high pressure pipe joint 10, operating room 11 and measuring tank 12 from front to back successively, and described gas engine 6 is connected with the input of fluid torque-converter 7; The two ends of described power transmission shaft 8 are connected with fluid torque-converter 7 output and fracturing pump 9 input respectively; Described fracturing pump 9 is connected with measuring tank 12 by pipeline, and the output of described fracturing pump 9 is connected with high pressure pipe joint 10; Between described gas engine 6 and LNG gas bottle device assembly 2, insulating 3 is installed.Can thermal insulation function be played by arranging insulating 3, can extension device application life.
Described gas engine 6 is LNG gas engine.Utilize LNG as fracturing device gas engine power source, can play certain facilitation to improving air quality, in energy-conserving and environment-protective, having very large potentiality, for user saves a large amount of fuel cost.
Described fracturing pump 9 is three cylinder plug fracturing pumps.
When carrying out fracturing work, first this car is parked in precalculated position by job requirements, closes main car; Well head high pressure pipe joint and this car fracturing pump 9 are exported high pressure pipe joint 10 be connected; Start the gas engine 6 on platform 4, whether observation instrument parameter is normal; Open liquid feed valve, delivery valve, by gas bottle device assembly 2 for gas engine 6 provides the energy, motor with LNG gas for fuel work, outputting power is through fluid torque-converter 7 speed change, drive power transmission shaft 8 to transmit the final fracturing pump 9 that drives and extract fracturing fluid from measuring tank 12, continuous compression fracturing fluid produces high pressure, outputs to wellhead manifold through high pressure pipe joint 10.
Operation of the present utility model controls to carry out in operating room 11, its control system adopts electric-gas to jointly control, and instrument console is equipped with engine controller, diesel engine accelerator control device, air gauge, ammeter, box oil pressure meter, transmission case oil temperature gauge, power end oil temperature gauge, power end oil pressure gauge, Hydraulic Transmission gearshift, shift indicator etc.Instrument console is also equipped with pressure flow monitor, and operator intuitively can obtain the instantaneous pressure of fracturing pump 9, instantaneous delivery and integrated flow.The maximum pressure of fracturing pump 9 can also be set simultaneously, can automatically make motor reduce to idling after pump pressure reaches setting pressure, guarantee use safety.According to fracturing pump 9 load variations, by Electronic Control gas engine 6 rotating speed, moment of torsion, fluid torque-converter 7 shift speed change; Non-follow control air valve open, control fracturing liquid into and out of.
The utility model structure is simple, while completing wellfracturing function, can greatly reduce depletion charge and exhaust emission, energy-conserving and environment-protective, safe and reliable, can extension device application life.
The utility model is not limited to above-mentioned embodiment, and in the ken that those skilled in the art possess, can also make a variety of changes under the prerequisite not departing from the utility model aim, the content after change still belongs to protection domain of the present utility model.
