Technical Field

The invention relates to a high-pressure multistage pump of an offshore platform, in particular to a scraping and blending device for a high-pressure multistage pump shaft bush of the offshore platform.

Background

The high-pressure multi-stage pump is one of the most main devices in platform production and is used for injecting water into an oil layer and improving the pressure of the oil layer, so that smooth oil exploitation is guaranteed. To ensure the normal production of the platform, the stable operation of the high-pressure multistage pump is extremely important.

In the process of assembling the high-pressure multi-stage pump, the scraping and the adjustment of the bearing bush are key quality control points of the high-pressure multi-stage pump assembly and are main factors influencing the stable operation of the high-pressure multi-stage pump.

The structure form of the bearing bush and the bearing box is divided! The bearing bush scraping is a repeated process, and the scraping needs to obtain a top gap, a bush side gap and a bush back gap between the bearing bush and a shaft. When the bearing box is hung, an upper cover of the bearing box is detached, the inner arc surface of the bearing bush is scraped by the upper and lower split bearing bushes through methods such as crossing, and whether the clearance of each part reaches the standard is checked through auxiliary tools such as red lead oil, a feeler gauge, a lead wire and a dial indicator. And hang repeatedly and cut and detect the in-process that reaches each clearance standard, need tens of times to tear repeatedly, adorn bearing box upper cover and fixing bolt and inside axle bush, and the bearing box upper cover is comparatively heavy, and it is inconvenient to dismantle, not only can cause the bodily injury risk in the handling process that relapses, dismouting greatly reduced work efficiency moreover.

Therefore, the change of the scraping and blending process of the bearing bush by a new technology is very important and is an urgent matter.

Disclosure of Invention

The invention aims to solve the problem of scraping and blending high-pressure multistage pump shaft bushes and provides a scraping and blending device for high-pressure multistage pump shaft bushes of an offshore platform.

The technical scheme adopted by the invention is as follows: a marine platform high pressure multistage pump shaft bush scraping and blending device includes:

the two fixing plates are fixedly connected to the lower end cover of the bearing box and are positioned on two sides of the bearing bush to be scraped;

the bottom parts of the two cantilevers are respectively hinged with the corresponding fixed plates, and the top parts of the two cantilevers are mutually connected through a connecting plate and used for adjusting the distance between the two fixed plates so as to be suitable for bearing bushes with different diameters; and the number of the first and second groups,

and the bearing bush pressing device is arranged on the connecting plate and used for pressing the bearing bush to be scraped.

Further, the bearing shell pressing device comprises:

the connecting bolt is connected to the connecting plate through threads; and the number of the first and second groups,

and the pressing plate is connected to the bottom of the connecting bolt and can move up and down under the rotation action of the connecting bolt to press the bearing bush to be scraped.

The invention has the beneficial effects that:

the scraping and blending device for the high-pressure multistage pump shaft bushing of the offshore platform has the advantages of simple structure, light weight, low cost, convenience in carrying and simplicity and convenience in operation; the process that traditional bearing box upper cover was torn open repeatedly, was adorned has been replaced, and the time that can effectual reduction axle bush scraping allotment improves work efficiency under the prerequisite of ensureing the quality, reduces the operation risk. The device is applied to the maintenance process of the high-pressure multi-stage pump, has good use effect and achieves the expected design effect.

Detailed Description

In order to further understand the contents, features and effects of the present invention, the following embodiments are illustrated and described in detail with reference to the accompanying drawings:

as shown in fig. 1 to 8, the device for scraping and blending the high-pressure multistage pump bearing bush of the offshore platform comprises two fixing plates 1, two cantilevers 2 and a bearing bush pressing device.

The two fixing plates 1 are fixedly connected to the lower end cover of the bearing box 6 and are positioned on two sides of the bearing bush 5 to be scraped, so that the bearing bush scraping and blending device is fixed to the lower end cover of the bearing box 6.

The bottoms of the two cantilevers 2 are respectively hinged with the corresponding fixed plate 1, and the cantilevers 2 can rotate around a rotating shaft at the hinged position; the tops of the two cantilevers 2 are connected with each other through a connecting plate 7. The cantilever 2 is used for adjusting the distance between the two fixed plates 1 so as to adapt to bearing bushes 5 with different diameters.

The bearing bush pressing device is arranged on the connecting plate 7 and used for pressing the bearing bush 5 to be scraped. The bearing bush pressing device comprises a connecting bolt 4 and a pressing plate 3. The connecting bolt 4 is connected to the connecting plate 7 through threads and used for pressing the pressing plate 3 and the bearing bush 5 to be scraped so as to fix the bearing bush 5 to be scraped; the pressing plate 3 is used for fixing the bearing bush 5 to be scraped and measuring the gap, the pressing plate 3 is connected to the bottom of the connecting bolt 4, and the pressing plate 3 can move up and down under the rotating action of the connecting bolt 4 to press the bearing bush 5 to be scraped.

The invention effectively solves the problem that the upper cover of the bearing box 6 is repeatedly disassembled and assembled in the scraping and blending processes of the bearing bush 5 of the high-pressure multistage pump, saves the maintenance time, and has simple structure and convenient assembly. The device is successfully applied to a plurality of water injection pumps, has good use effect and achieves the expected design effect.

Although the preferred embodiments of the present invention have been described above with reference to the accompanying drawings, the present invention is not limited to the above-described embodiments, which are merely illustrative and not restrictive, and those skilled in the art can make many modifications without departing from the spirit and scope of the present invention as defined in the appended claims.
