In above-described embodiment, the first conveying mechanism, second conveyor structure and the 3rd conveying mechanism include hydraulic ram 50 and pressurized cylinder 60, the external part of the piston rod 51 of hydraulic ram 50 is provided with supercharging cock body 53, forms supercharging cock body, and supercharging cock body 53 is arranged in pressurized cylinder 60 movably.Each driving engine 20 drives at least one oil pump 31.In the first conveying mechanism, in hydraulic ram 50, second conveyor structure, in hydraulic ram 50 and the 3rd conveying mechanism, the rod chamber 41 of hydraulic ram 50 is communicated with successively, control cock group 36 is connected between multiple oil pumps 31 and the first conveying mechanism, second conveyor structure, the 3rd conveying mechanism, for controlling in the first conveying mechanism hydraulic ram 50, second conveyor structure the rodless cavity oil inlet and oil return state of hydraulic ram 50 in hydraulic ram 50 and the 3rd conveying mechanism.Wherein, the rod chamber 52 of the hydraulic ram 50 of each conveying mechanism is communicated with successively.Control cock group is used for the oil inlet and oil return state of the rodless cavity of controlling each oil cylinder 50.
In addition, the supercharging cock body of being located at piston rod 51 external parts of each hydraulic ram 50 can adopt various ways, requirement can realize supercharging cock body in pressurized cylinder 60, stretch back and forth into, and make pressurized cylinder 60 outlet suck or discharge fracturing fluid.For example, this supercharging cock body can be that piston rod 51 external parts self form, and can be also piston or the plunger etc. that is connected in piston rod external part.
Like this, the mouth of every diesel motor connects at least one oil pump mating with it, all oil suctions from hydraulic reservoir when each operation of oil pump, fluid converges after oil pump, thereby the horsepower output of realizing diesel motor converges, fluid after converging can drive fracturing pump by hydraulic ram, has also just realized the parallel running of diesel motor.The fracturing truck of the present embodiment adopts at least two power plants and supporting driving system thereof, thereby is convenient to type selecting, can effectively reduce the manufacturing cost of fracturing truck, effectively improves equipment reliability of operation.
As shown in Figure 5, in fracturing truck working process, the outlet of pressurized cylinder 60 all can connect dispense fluid 70 and manifold system, and in the course of the work, multiple driving engines 20 start, drive multiple oil pumps 31 to turn round, control cock 36 is moved, and controls the rodless cavity oil-feed of at least one oil cylinder 31, the rodless cavity oil return of other oil cylinders 31, thereby pressurized cylinder 60 is sucked fracturing fluid and continuous wave output, to meet the needs of frac job by dispense fluid 70.
Compared with prior art, the oil cylinder of each conveying mechanism can adopt different cylinder diameters, and correspondingly, corresponding pressurized cylinder also can adopt different cylinder diameters, and oil cylinder and pressurized cylinder cooperatively interact and can realize the multiple discharge capacity requirement under different pressures thus, and coverage is wider.Moreover the stroke of oil cylinder and pressurized cylinder is larger, the number of times that commutates when operation is less, linear velocity is lower, can effectively improve like this service life of conveying mechanism associated components (as pressurized cylinder, oil cylinder etc.).And, while adopting multiple driving engine, under the prerequisite that meets maximum power, the power that each driving engine is born can effectively reduce, thereby, can select common small power motor, so also greatly improved type selecting scope, correspondingly, the type selecting scope of the Hydraulic Elements such as each oil pump, each oil cylinder, each pressurized cylinder also can effectively improve, effectively reduce and realize difficulty, be also convenient to realize multiple matching way.
In addition, adopt after this type of drive, each driving engine, each oil pump, each oil cylinder and each pressurized cylinder etc. are easy to obtain, and implement easily, without being subject to import, special restriction, thereby can effectively reduce the component costs of fracturing truck drive transfer system.It is to be noted, adopt after this type of drive, if after some driving engines or oil pump damage, whole drive transfer system still can ensure that frac job proceeds a period of time, thereby effectively improved safe reliability, reduce construction party the risk of losing has occurred.
Described in the various embodiments described above, compared with prior art, the utlity model has following advantage:
The fracturing truck of the utility model design, adopt many driving engines or electrical motor and corollary equipment thereof as power system, booster body is converged power be passed in cooperation by driving system, this not only reduces the parts selection difficulty such as driving engine and supporting transmission gearbox, also effectively reduce manufacturing cost and the production difficulty of fracturing truck, can reduce costs, improve equipment reliability of operation, effectively improve the maintainability of operating efficiency and equipment simultaneously.
