Abstract
The invention relates to the technical field of petroleum, in particular to a novel buffer device for a fracturing pump. The novel buffer device comprises a pressing plate (1), a fixing seat (2), a buffer tube (3), a fixing clamp (4), a gas channel (5) and a gas bottle (6). According to the novel buffer device, the structure is simple, the cost is low, the mounting is convenient, the utilization is safe and reliable, the impact of a fracturing fluid on a fluid end of the fracturing pump is solved, parts inside the liquid end are effectively protected, and the service life of the entire fracturing pump is prolonged.
Description
Technical field
The present invention relates to petroleum technology field, be specifically related to a kind of novel fracturing pump buffer unit.
Background technology
Fracturing unit truck is mainly made up of four big parts such as carriage chassis (or sledge), electromotor, change speed gear box, fracturing pumps, and wherein fracturing pump is the working host of fracturing unit truck, is often maintained, to improve its life-span.Fracturing pump is made up of power end and fluid end two large divisions, and its fluid end, due to the long impact shock of fracturing fluid, causes fatigue damage to internal parts, shortens the expected service life of integral hydraulic fracturing pump.
Summary of the invention
The present invention is to solve the fracturing fluid impact shock to fracturing pump fluid end, delaying the service life of fracturing pump, it is provided that a kind of novel fracturing pump buffer unit.
The technical scheme is that a kind of novel fracturing pump buffer unit, it is made up of pressing plate (1), fixing seat (2), separator tube (3), fixing card (4), gas passage (5) and gas cylinder (6), during fracturing pump work, this device entirety is put into the suction manifold of fracturing pump.
It is an advantage of the current invention that: simple in construction, with low cost, safe and reliable, can significantly buffer the fracturing fluid impact to fracturing pump fluid end, be effectively increased the service life of fracturing pump.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
Fig. 2 is the scheme of installation of the present invention.
In figure: 1. pressing plate, 2. fix seat, 3. separator tube, 4. fixing card, 5. gas passage, 6. gas cylinder, 7. suction manifold, 8. suction manifold liquid outlet
Detailed description of the invention:
Below in conjunction with the accompanying drawings embodiment of the present invention are illustrated:
As it is shown in figure 1, the one of the present invention novel fracturing pump buffer unit, it is made up of pressing plate (1), fixing seat (2), separator tube (3), fixing card (4), gas passage (5) and gas cylinder (6).Before fracturing pump works, this device is positioned in suction manifold (7), gives separator tube (3) aerating by gas cylinder (6) so that it is reach the stationary state of fixing seat (2).When fracturing pump works, fracturing fluid enters in pipe by suction manifold entrance, owing to the two ends of separator tube (3) are fixed by pressing plate (1) and fixing card (4), fracturing fluid will not enter into inside, only can flow between the inwall of the outside of separator tube (3) and suction manifold (7), owing to the surface of separator tube (3) is round and smooth, in certain cleanliness, therefore fracturing fluid slowly can flow in suction manifold (3), it is flowed in fracturing pump fluid end from suction manifold liquid outlet (8), decrease the impact to fracturing pump fluid end internal part, improve the service life of integral hydraulic fracturing pump.
The foregoing is only preferred embodiments of the present invention, not in order to limit the present invention, all within the spirit and principles in the present invention, any amendment made, equivalent, improvement etc., should be included within the scope of the present invention.
Claims (4)
1. a novel fracturing pump buffer unit, is made up of pressing plate (1), fixing seat (2), separator tube (3), fixing card (4), gas passage (5) and gas cylinder (6).
