The utility model aims at providing an avoid the frequent change of water injection pump, improve water injection pump mid-section sealing performance's seal structure.
Description
Technical Field
The utility model relates to an ocean platform water injection pump technical field especially relates to a seal structure that is arranged in ocean platform water injection pump to divide face.
Background
The water injection pump is one of the most main devices in platform production and is used for injecting water into an oil reservoir and improving the pressure of the oil reservoir, so that smooth oil exploitation is guaranteed. To ensure the normal production of the platform, the stable operation of the water injection pump is extremely important.
At present, most of the structure types of the water injection pump of the offshore platform are of a central opening type, and the sealing of the middle section of the water injection pump plays a decisive role in the normal operation of the water injection pump. In the maintenance process of recent years, the middle section high-pressure gasket is easy to wash, so that the middle section of the water injection pump is seriously corroded, the sealing is not tight, the water is seriously torn off, and the high vibration of equipment is caused. The problem of zonal sealing in water injection pumps has become a major failure and a significant safety hazard for water injection pumps. Because the change of every time sealed is inside the water injection pump, must stop the pump and transport back to land overhaul, and the maintenance procedure is loaded down with trivial details, and cost of maintenance is higher, and the maintenance scheme includes: firstly, the planes of the upper cover and the lower cover of the pump are machined again to grind the two planes, and holes of each pump shell opening ring are bored after the pump covers are folded, so that the difficulty is high, the period is long, and potential safety hazards exist under the condition that the strength of the pump body cannot be changed; secondly, the pump shell needs to be returned to a manufacturer for structure reinforcement or the pump shell needs to be customized again, so that not only is the cost high, but also the manufacturing period of the pump shell is long.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to overcome not enough among the above-mentioned prior art, aim at providing one kind and avoid the frequent change of water injection pump, improve the seal structure of the section sealing performance in the water injection pump.
In order to achieve the above purpose, the technical scheme of the utility model is realized like this:
a sealing structure for a water injection pump middle section of an ocean platform comprises the water injection pump middle section, wherein bolt holes are formed in the water injection pump middle section, special-shaped grooves surrounding the outer sides of impellers on a water injection pump rotor are formed in the two sides of the water injection pump rotor of the water injection pump middle section, each special-shaped groove is provided with branches located between the impellers, and each branch extends to the water injection pump rotor; a strip-shaped special-shaped ring is arranged in the special-shaped groove; and a high-pressure gasket covering the middle section of the water injection pump is paved on the special-shaped ring.
Furthermore, the section of the special-shaped groove and the section of the special-shaped ring are both semicircular, and the special-shaped ring is also provided with outer edges extending out of two sides of the section of the special-shaped groove.
Furthermore, the special-shaped ring is of an integrated structure with the same shape as the special-shaped groove.
Compared with the prior art, the utility model discloses following beneficial effect has:
the utility model discloses a divide the face to forge and mill out special-shaped groove in the water injection pump, bond special-shaped circle at the inslot, special-shaped circle pressurized inflation forms double-deck sealed with high-pressure gasket. The utility model discloses simple structure, simple to operate, the cost is lower, can effectual solution water injection pump in the sealed problem of facet.
