Description
Technical field:
The utility model relates to the used a kind of spray gun of down-hole, oil field antisepsis oil pipe inwall spray coatings, down-hole, especially a kind of oil field antisepsis oil pipe internal diameter high-pressure airless spraying gun.
Background technology:
People generally use methods such as cylinder, brush and compressed air spraying on the paint brushing technique, why these methods are popularized, simple with its outfit, cost of investment is low, and is applied widely, be not subjected to the advantages such as restriction of conditions such as application place, environment relevant, but these modes are comparatively original, and labor strength is big, and production efficiency is low, brush paint film and easily produce brush mark, film thickness is inhomogeneous.Though compressed air spraying labour intensity, labor productivity make moderate progress than manual painting, but painted the certain limitation of viscosity, and when spray painting operation, produced a large amount of coating clouds, not only wasted solvent and paint vehicle, serious is to bring very big influence to painter people's health.
Airless spraying is the new technology that just grew up in recent years, is characterized in the production efficiency height, and coating cloud is less during operation, so general compressed air spraying has improved working condition, formed paint film is evenly tight, and anti-corrosive properties are good.Be specially adapted to large tracts of land spraying (as boats and ships, bridge, rolling stock, plant equipment and building structure etc.), range of application is wider.
Airless spraying is a new technology of paint spraying technology, and it is different fully with the principle of general compressed-air spraying.Generally spraying paint is to utilize compressed air to produce negative pressure in spray gun, will coat with lacquer stream and take and dispel into particulate out of, sprays to workpiece.This spraying method because compressed air, flies upward the lacquer grain and is diffused into and goes in the ambient atmosphere, add the volatilization of solvent, so coating cloud is more, has not only wasted a large amount of paint vehicles, and has influenced working condition.By comparison, the advantage of airless spraying is more obvious, not only utilize compressed air that the lacquer grain is sprayed on the workpiece, and make paint be pressed onto 10～40Mpa (more than the 100kg/cm2 pressure) by high-pressure pump, then by special nozzle aperture ejection, after the high pressure lacquer leaves in the nozzle arrival atmosphere, just acutely expand at once, be atomized into superfine lacquer grain and be sprayed onto on the surface of the work.It only borrows compressed air, and (4～6kg/cm2) drive high-pressure pump, make the paint supercharging, and compressed air does not directly contact with paint, are not mixed with compressed air in the high pressure lacquer stream that therefore is pressurized, so be referred to as airless spraying.Owing to there is not compressed air to exist in the paint vehicle, so also just do not paint and AIR MIXTURES, the coating cloud that flies upward in the atmosphere is just less, and working condition is more much better than compressed-air spraying.The more important thing is, airless spraying does not need air atomizing, it is few to disperse, the utilization rate height, greatly reduce the environmental pollution index, reduced the harm that lacquerer is subjected to harmful substance, but in the anticorrosion process of oil field, because the specialized character structure of oil pipe, common portable high-pressure airless spraying gun can't be deep into pipe aperture.
The utility model content:
In order to solve the problem that exists in the background technology, the utility model provides down-hole, a kind of oil field antisepsis oil pipe internal diameter high-pressure airless spraying gun, this spray gun can be deep into pipe aperture, tube inner wall is sprayed, have paint film evenly closely, fineness is good, Corrosion Protection is good characteristics, also have the characteristics that can spray in extensive range, high efficiency, long service life simultaneously.
The technical solution of the utility model is: this down-hole, oil field antisepsis oil pipe internal diameter high-pressure airless spraying gun comprises high-pressure pump, high-pressure pump connects the paint vehicle funnel by pipeline, high-pressure pump is installed on the trolley frame, one end of the trolley frame gun shot that has been connected through the hinge, at least one abrasionproof device is installed on the gun shot, high pressure transmission pipe line in high-pressure pump and the gun shot is connected, and the end of high pressure transmission pipe line is equipped with motor and nozzle, and nozzle is uniform porose on the hollow round table-like and wall.
200 apertures that diameter is 0.8mm evenly distribute on the nozzle.
The beneficial effects of the utility model are: this novel pipe aperture that is deep into, tube inner wall is sprayed, and have following characteristics: 1, painting quality is good: high pressure is sprayed paint and two kinds of painting qualities that technology sprayed of manual painting compare with comparison method.Be coated with by hand the coating surface of mopping, find to have many apertures, second road to still have some aperture not fallen by topped with lens examination first road.During to the 3rd road, just that whole apertures are topped, but after picking brokenly with pin, find that only cover on the surface, still fail to contact with steel plate.And with the high pressure construction of spraying paint, once spraying just can be infiltrated slit or recess, and is more suitable on the smart rough surface after the rust cleaning.Paint film that high pressure painting forms is evenly tight, and fineness is good, and the Corrosion Protection test is more effective than manual brushing; 2, production efficiency height: manual brushing per minute is only brushed 0.3～5.5m
2, and everyone every spray gun of high pressure painting can spray 3.5～5.5m
2, can improve ten times of work efficiency, remove plant maintenance, cleaning and other back work consume, and actual efficiency can improve more than 5 times, and is more remarkable to the large tracts of land spraying; 3, can spray in extensive range.The lacquer kind that can spray has: shipbottom paint, hull paint, enamel paint, red lead paint, bituminous epoxy paint, chlorinated rubber aluminium paint, zinc rich primer etc.Paint vehicle viscosity below 100S, fineness can pass through 100 orders/time 2 filter screens all can spray.
