Abstract
The utility model discloses a connecting structure of a drilling pump cylinder liner, which comprises a discharging hydraulic cylinder (2), a cylinder liner (3), a cylinder liner gland (4) and a cylinder liner seat (5). The cylinder liner (3) is pressed tightly on the cylinder liner seat (5) through the cylinder liner gland (4), a wear-resistant plate (6) is arranged between the cylinder liner (3) and the discharging hydraulic cylinder (2), a limiting flange is formed at the end of the cylinder liner seat (5), and the end face of the cylinder liner seat (5) contacts with the discharging hydraulic cylinder (2). The connecting structure is simple in structure, can fix the discharging hydraulic cylinder and the cylinder liner seat through adjusting the cylinder liner seat, not only simplifies the original independent fixing structure but also brings convenience to installation and detachment of the cylinder liner seat.
Description
Technical field
The utility model belongs to petroleum and natural gas drilling equipment field, relates to a kind of linkage structure of cylinder sleeve of drilling pump concretely.
Background technique
In the oilfield drilling operation, drilling pump fluid end cylinder sleeve flange all adopts bolt and nut with itself and wear-resisting dish with to discharge fluid cylinder fastening.As shown in Figure 3: discharge fluid cylinder 8 and be fixed on the frame 10 by bolt 9, and cylinder sleeve flange 11 is fixed on the discharge fluid cylinder 8 by a circle connecting bolt 12, this structure mainly contains the shortcoming of following two aspects: 1, installing/dismounting needs fixing separately respectively, process is more loaded down with trivial details, and waste time and energy, be not easy to the high efficiency work in well site; 2, the maintaining time is long.
The model utility content
The purpose of this utility model provided a kind of simple in structure, connect reliably, especially conveniently install, the linkage structure of dismounting, a kind of cylinder sleeve of drilling pump of safeguarding.
The technical solution of the utility model is as follows:
A kind of linkage structure of cylinder sleeve of drilling pump, comprise and discharge fluid cylinder, cylinder sleeve, cylinder sleeve gland and cylinder sleeve seat, described cylinder sleeve is pressed on the described cylinder sleeve seat by described cylinder sleeve gland, be provided with wear-resisting dish between described cylinder sleeve and the described discharge fluid cylinder, described cylinder sleeve seat end forms defining flange, and described cylinder sleeve seat end face contacts with described discharge fluid cylinder.
Adopt the said structure key to be: to form defining flange at cylinder sleeve seat front end, just can when fixing the discharge fluid cylinder, the cylinder sleeve seat be pressed on the discharge fluid cylinder by this flange, so just saved structures such as connecting screw and bolt need be set separately, made the purpose that promptly reaches the stationary cylinder block set make things convenient for its installing/dismounting again.
Also comprise frame, described discharge fluid cylinder and cylinder sleeve seat are arranged on the described frame, and described defining flange is in described frame and discharges the fluid cylinder long splice and close between the face.
Described discharge fluid cylinder is bolted to connection on described frame, in fixing discharge fluid cylinder described cylinder sleeve seat defining flange is clamped between described frame and the discharge fluid cylinder.
Form screw-thread fit between described cylinder sleeve gland outer ring and the described cylinder sleeve seat inner ring.
Beneficial effect: the utility model is simple in structure, by the adjustment to the cylinder sleeve stand structure realized fixing discharge fluid cylinder in to the fixing of cylinder sleeve seat itself, not only simplified original independent stationary structure but also made things convenient for the installing/dismounting of cylinder sleeve seat.
Description of drawings
The utility model will illustrate by example and with reference to the mode of accompanying drawing, wherein:
Fig. 1 structural representation of the present utility model;
Fig. 2 is the A place enlarged view of Fig. 1;
Fig. 3 is the structural representation in the background technique.
Embodiment
As shown in Figure 1, 2: a kind of linkage structure of cylinder sleeve of drilling pump, comprise frame 1, discharge fluid cylinder 2, cylinder sleeve 3, cylinder sleeve gland 4 and cylinder sleeve seat 5, described discharge fluid cylinder 2 and cylinder sleeve seat 5 are arranged on the described frame 1, described cylinder sleeve 3 is pressed on the described cylinder sleeve seat 5 by described cylinder sleeve gland 4, be provided with wear-resisting dish 6 between described cylinder sleeve 3 and the described discharge fluid cylinder 2, described cylinder sleeve seat 5 ends form defining flange, described defining flange is in described frame 1 and is connected between the junction plane with discharge fluid cylinder 2, and described cylinder sleeve seat 5 end faces contact with described discharge fluid cylinder 2.
Also comprise frame 1, described discharge fluid cylinder 2 is fixedly connected on the described frame 1 by bolt 7, in fixing discharge fluid cylinder 2 described cylinder sleeve seat 5 defining flanges is clamped between described frame 1 and the discharge fluid cylinder 2.
Form screw-thread fit between described cylinder sleeve gland 4 outer rings and described cylinder sleeve seat 5 inner rings.
The cylinder sleeve of drilling pump stand structure of fast assembling-disassembling has directly replaced the cylinder sleeve flange in the existing structure, and in assembly process, the frame of at first the cylinder sleeve seat being packed into will be discharged fluid cylinder then and frame is connected and fixed, and realizes being fixedly clamped to the cylinder sleeve seat in the connection procedure; And unloading process only need take off earlier and discharges fluid cylinder and hammering cylinder sleeve seat end face get final product, and reaching the purpose of quick mounting or dismounting cylinder sleeve seat, thereby the fast assembling-disassembling of realization drilling pump effectively improves its working efficiency.
