Description
Technical field
The utility model relates to a kind of novel fracturing unit truck with self-suction function.
Background technology
Existing fracturing unit truck is all networking work, there is no independent suction capacity, all unifies by unified feed flow after the fracturing blender truck supercharging.Equipment obtains weak point and is like this, the separate unit fracturing unit truck can not work alone, and must will provide liquid by fracturing blender truck, and casing fracturing is more and more general now simultaneously, small-sized fracturing unit truck does not in the past have enough pressure and discharge capacity to carry out the pressure of balancing sleeve the inside, easily oil pipe is caused to damage.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of novel fracturing unit truck with self-suction function, a car of having realized conventional fracturing unit truck is multiplex, when normal operation, by the driven by engine gearbox, drive large pump through power transmission shaft, get to the down-hole face after the liquid pressing prepared by fracturing blender truck, when bicycle uses, the centrifugal pump carried by fracturing unit truck is given large pump feed flow, then annotates and goes to the down-hole face.The operation of complete machine is realized by Circuits System, hydraulic system, air-channel system and machine driven system.All control all concentrates on console, by a people, completed, and convenient and reliable operation, automaticity is high.
For solving the problems of the technologies described above, the utility model is realized as follows: a kind of novel fracturing unit truck with self-suction function comprises motor, hydraulic transmission box, fuel tank, power transmission shaft, Five-cylinder piston pump, centrifugal pump, high-pressure outlet on chassis vehicle, platform; On platform, motor is fixed on chassis vehicle driver's cabin back, hydraulic transmission box is screwed and is connected with motor on platform, power transmission shaft couples together hydraulic transmission box and Five-cylinder piston pump, fuel tank is fixed on the top of power transmission shaft, high-pressure outlet is connected with Five-cylinder piston pump by screw thread, and centrifugal pump is screwed in chassis vehicle afterbody side.
Good effect of the present utility model is: the utility model has carried out an improvement for conventional fracturing unit truck, increased a perfusion centrifugal pump, given on separate unit car band the ability of self-priming, the fracturing unit truck of separate unit can not only networking work like this, also can construct by the separate unit car simultaneously, also can when casing fracturing, play the effect of balance oil pipe simultaneously.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As shown in Figure 1, a kind of novel fracturing unit truck with self-suction function described in the utility model, comprise motor 2 on chassis vehicle 1, platform, hydraulic transmission box 3, fuel tank 4, power transmission shaft 5, Five-cylinder piston pump 6, centrifugal pump 7, the first butterfly valve 8, the second butterfly valve 9, the 3rd butterfly valve 10, high-pressure outlet 11.
On platform, motor 2 is fixed on chassis vehicle 1 driver's cabin back, hydraulic transmission box 3 is screwed and is connected with motor on platform 2, power transmission shaft 5 couples together hydraulic transmission box 3 and Five-cylinder piston pump 6, fuel tank 4 is fixed on the top of power transmission shaft 5, high-pressure outlet 11 is connected with Five-cylinder piston pump 6 by screw thread, and centrifugal pump 7 is screwed in chassis vehicle 1 afterbody side.
Operating principle: work is to drive hydraulic transmission box 3 by power transmission shaft 5 by motor on platform 2, drive Five-cylinder piston pump 6 work, normal networking pressure break formula, close the second butterfly valve 9 and open the 3rd butterfly valve 10, be connected and provide fluid power to Five-cylinder piston pump with the fracturing blender truck of feed flow by external manifold, by high-pressure outlet 11, receive in the well casing remittance and go after the Five-cylinder piston pump pressurization.
When unit is worked, close the 3rd butterfly valve 10, open the first butterfly valve 8 and the second butterfly valve 9, external fluid power is given Five-cylinder piston pump 6 feed flows by centrifugal pump 7, then, through after Five-cylinder piston pump 6 pressurizations, by high-pressure outlet 11, is discharged to the down-hole face.
Motor, under the state of permanent rotating speed, is controlled large pump delivery and pressure by the gear of gearbox, and car load, with a perfusion centrifugal pump, has increased the work of self-priming simultaneously, can meet the instructions for use of separate unit car.Do not need the concentrated industry of fracturing blender truck, just can realize pressing crack construction.
This equipment is equipped with overpressure protection apparatus and pressure change protection device, and when the pressure of pump surpasses predetermined pressure or pressure jump and surpasses predetermined value, this device works, and makes engine idle, and plunger displacement pump quits work.
Good effect of the present utility model:
1, the utility model can meet the requirement of fracturing unit truck bicycle independent construction.
When 2, the utility model can solve casing fracturing, meet the requirement that the interior large discharge capacity of oil pipe is tied weighing apparatus.
3, the utility model pressure when operation is realized the operation of networking and unit, has saved the space in well site, has realized the requirement of a tractor serves several purposes.
