Abstract
The utility model relates to an anticorrosive spraying device of oil pipe inner wall. Anticorrosive spraying device of oil pipe inner wall, its characterized in that, including the coaster, the coaster setting is provided with the water tank and scribbles the workbin on the support body on the coaster, and the water tank passes through the water inlet and delivery port intercommunication of water pump and spraying pipe, scribbles the coating union coupling that the workbin passes through coating pump and spraying pipe, manages corresponding first seal box and the second seal box of being provided with with the spraying. The utility model discloses production efficiency is high, can realize continuous automatic spraying, and the coating loss is little.
Description
Technical field
The utility model relates to a kind of tube inner wall anti-corrosion spray device.
Background technology
The corrosion failure of oil pipe at home and abroad oil field is a very universal phenomenon.There is a large amount of waterflooding oil field in China oil field, and injection well tubing corrosion is particularly serious, corrodes the fastest only 3 years seepage will occur, and corrosion rate is up to 2.6mm/a.Therefore, all oil pipes just under arms all have employed various anti-corrosion measure in recent years.As conventional coating tubing, Ni-P plated oil pipe, three layers meet plating oil pipe etc.These techniques serve key effect for solution oil pipe anti-corrosive, but, all there is no complete tube inner wall coating equipment, have impact on oil pipe anti-corrosive construction operation efficiency.
Summary of the invention
The utility model is exactly the blank for prior art, provides a kind of oil pipe tube inner wall anti-corrosion spray device.This device can realize automation loading and unloading, easy to use, and production and construction is effective, efficiency is high.
Tube inner wall anti-corrosion spray device, comprise coaster, coaster is arranged on support body, coaster is provided with water tank and coating case, water tank is communicated with delivery port with the water inlet of spray pipe by water pump, coating case is connected with the coating pipe of spray pipe by paint pump, and corresponding with spray pipe is provided with the first seal box and the second seal box.
Concrete, the first seal box is connected negative pressure air-suction device with the second seal box by pipeline.
Concrete, support body is also provided with roller for supporting spray pipe.
Concrete, described spray pipe comprises outer tube, the two ends sealing of outer tube, be provided with coating pipe and water pipe in outer tube, one end of water pipe is positioned at outer tube, and the other end of water pipe stretches out outside spray pipe, outer tube wall is provided with water inlet, and the other end of coating pipe stretches out outer tube and is provided with shower nozzle.
Concrete, on the first seal box corresponding coaster sidewall on be provided with limit sensors.
The utility model promotes spray pipe at oily in-pipe by coaster, realizes the object to tube inner wall coating anticorrosive paint.Spray pipe arranges hollow, is lowered the temperature to spray pipe by water, avoids because high temperature causes spray pipe to be out of shape.Oil pipe two ends are sealed, and by negative pressure air-suction device, the coating of volatilization is absorbed, avoid pollution, energy-conserving and environment-protective.The utility model production efficiency is high, can realize continuous automatic coating, and coating loss is little.

Detailed description of the invention
As shown in the figure, tube inner wall anti-corrosion spray device, comprises coaster, and coaster is arranged on support body, support body is also provided with roller for supporting spray pipe.Coaster is provided with water tank and coating case, water tank is communicated with delivery port with the water inlet of spray pipe by water pump, coating case is connected with the coating pipe of spray pipe by paint pump, described spray pipe comprises outer tube, and the two ends sealing of outer tube, is provided with coating pipe and water pipe in outer tube, the delivery port of water pipe stretches out water pipe, the other end of water pipe is positioned at outer tube and opening, and outer tube wall is provided with water inlet, and the other end of coating pipe stretches out outer tube and is provided with shower nozzle.Corresponding with spray pipe is provided with the first seal box and the second seal box.First seal box is connected negative pressure air-suction device with the second seal box by pipeline.On first seal box corresponding coaster sidewall on be provided with limit sensors.
During use, oil pipe two ends are placed in the first seal box and the second seal box.Coaster slides, and spray pipe stretches into the first seal box, and stretches into the far-end of oil pipe to oil pipe.Then, start spraying, coaster retreats, and water cools spray pipe simultaneously.Pipe to be sprayed exits from oil pipe, when exiting to limit sensors place, controls paint pump quit work by controller.Change oil pipe to be sprayed, again spray.
Finally should be noted that: above embodiment is only in order to illustrate that the technical solution of the utility model is not intended to limit; Although be described in detail the utility model with reference to preferred embodiment, those of ordinary skill in the field have been to be understood that: still can modify to detailed description of the invention of the present utility model or carry out equivalent replacement to portion of techniques feature; And not departing from the spirit of technical solutions of the utility model, it all should be encompassed in the middle of the technical scheme scope of the utility model request protection.
