Description
Technical field
The utility model relates to a kind of fracturing pump, particularly relates to a kind of seal ring of fracturing pump spool.
Background technique
Existing fracturing pump spool adopts straight flange to be connected with the cooperating structure of seal ring to coordinate, this mode not only makes spool and seal ring manufacture difficulty---the not easily demoulding after casting, and can sharp transitions be produced due to cooperation place, stress is caused to concentrate, thus accelerate the damage (working life only has 5 hours) of seal ring, having is exactly that this fit system easily causes seal ring to come off again, and impact uses.
Model utility content
Because the above-mentioned defect of prior art, technical problem to be solved in the utility model is to provide and is a kind ofly easy to processing, difficult drop-off, the fracturing pump spool of long service life and seal ring cooperating structure.
For achieving the above object, the utility model provides the cooperating structure of a kind of fracturing pump spool and seal ring, comprise spool and seal ring, the assembling cross section of described spool and seal ring is assembled concave circular arc in straight flange, second, the 3rd by first and is assembled hypotenuse, the 4th and assemble straight flange, the 5th and assemble hypotenuse and be connected, described first assembling straight flange and the 3rd assemble hypotenuse and passes through the second indent circular sliding slopes, and the described the 3rd assembles hypotenuse and the 5th assembles hypotenuse and assemble straight flange by the 4th and be connected; It is mutually vertical that described first assembling straight flange and the 4th assembles straight flange, and the described the 3rd assembles hypotenuse and the 5th assembles hypotenuse and assemble straight flange to the 4th and tilt to be connected.
The beneficial effects of the utility model are: the utility model low cost of manufacture, assembling stable (difficult drop-off), and long service life, after improving, the life-span improves about 2 times.
Accompanying drawing explanation
Fig. 1 is existing seal ring and spool assembly structure figure.
Fig. 2 is existing ring structure figure.
Fig. 3 is the structural representation of the cooperating structure embodiment of the utility model one one kinds of fracturing pump spools and seal ring.
Fig. 4 is the ring structure figure of the cooperating structure embodiment of the utility model one one kinds of fracturing pump spools and seal ring.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail:
See Fig. 1 to Fig. 2, existing spool 7 is connected by the first straight flange 2, second straight flange 3, the 3rd straight flange 4, the 4th straight flange 5, the 5th straight flange 6 with the assembling cross section of seal ring 1, the first described straight flange 2 is parallel with the 4th straight flange 5, the 3rd described straight flange 4 is parallel with the 5th straight flange 6, and the 3rd described straight flange 4 is vertical with the 4th straight flange 5; The first described straight flange 2 tilts to be connected by the second straight flange 3 with the 3rd straight flange 4.
Owing to being connected by sharp angles between each adjacent straight flange, this can cause joint stress to concentrate, and has a strong impact on working life; And when manufacturing corresponding spool and seal ring, because section is all connected by straight flange, adopt mach words can there is certain processing dead angle, adopt casting can produce demoulding difficulty, therefore its manufacture difficulty is relatively high, cost of production is also thereupon higher.And in use seal ring occur loosen even come off, had a strong impact on product use stability.Especially the second straight flange 3, the 3rd straight flange 4, the 4th straight flange 5 short slot of encircling a city, its short slot width is relatively little, complex structure and sharp transitions point is more.
See Fig. 3 to Fig. 4, the cooperating structure of a kind of fracturing pump spool and seal ring, comprise spool 9 and seal ring 8, the assembling cross section of described spool 9 and seal ring 8 is assembled concave circular arc 11, the 3rd in straight flange 10, second by first and is assembled hypotenuse 12, the 4th and assemble straight flange 13, the 5th and assemble hypotenuse 14 and be connected, described first assembling straight flange 10 and the 3rd is assembled hypotenuse 12 and is connected by concave circular arc 11 in second, and the described the 3rd assembles hypotenuse 12 and the 5th assembles hypotenuse 14 and assemble straight flange 13 by the 4th and be connected; It is mutual vertical that described first assembling straight flange 10 and the 4th assemble straight flange 13, and the described the 3rd assembles hypotenuse 12 and the 5th assembles hypotenuse 14 and assemble straight flange 13 to the 4th and tilt to be connected;
Original short slot of being encircled a city by the second straight flange 3, the 3rd straight flange 4, the 4th straight flange 5 is made into the round and smooth excessive groove be made up of concave circular arc 11, the 3rd assembling hypotenuse 12 in the first assembling straight flange 10, second by this structure, more be beneficial to processing, effectively can reduce difficulty of processing, and change the sharp transitions of original short slot, effectively reduce its internal stress to concentrate, improve life of product; And effective rubbing surface of this structure spool and seal ring when making to use more greatly, make seal ring difficult drop-off, Assembly stability is higher.
More than describe preferred embodiment of the present utility model in detail.Should be appreciated that those of ordinary skill in the art just can make many modifications and variations according to design of the present utility model without the need to creative work.Therefore, all technician in the art according to design of the present utility model on the basis of existing technology by the available technological scheme of logical analysis, reasoning, or a limited experiment, all should by the determined protection domain of claims.
