Description
Technical field
The invention belongs to diesel engine re-manufacturing technology field, particularly relate to a kind of reproducing method of high-pressure oil pipe.
Background technology
High-pressure oil pipe carries the task of conveying high-pressure fuel oil, and its requirement of strength is very high.High-pressure oil pipe is one of important spare part of diesel engine, is assembling unit structure on a diesel engine.Manufactured in the process of diesel engine in production in the past, the high-pressure oil pipe sub-assembly of directly assembling is new product, and the high-pressure oil pipe sub-assembly dismantled from old machine is directly discarded again.But part high-pressure oil pipe is in good condition in discarded high-pressure oil pipe sub-assembly, therefore takes the mode of production to old high-pressure oil pipe is directly discarded to cause very large waste to resource, does not meet country and carried out the original intention manufacturing pilot business more originally.
Manufacturing is a kind of industry waste product being implemented to high-tech reparation and transformation again, its for be damage or be about to the parts scrapped, on the basis that performance failure analysis, life appraisal etc. are analyzed, carry out Rebuilding engineering design, adopt recovery technique, by workpiece shapes and accuracy resumption, the quality that makes to manufacture a product again meets or exceeds new product.
High-pressure oil pipe is again in manufacture process, and a most primary ring carries out sorting inspection to old high-pressure oil pipe, finds out high-pressure oil pipe out of order.Old high-pressure oil pipe surface all covers paint with anti-corrosion, and dislikes slightly due to the working environment of old diesel engine, and a large amount of greasy dirt of high-pressure oil pipe surface contamination, cannot check the defect condition of high-pressure oil pipe.
At present, in existing high-pressure oil pipe re-manufacturing technology, the high-pressure oil pipe dismantled first is cleaned, remove surperficial most of spots such as greasy filth, then utilize solvent or diluent to scrub high-pressure oil pipe surface paint, after paintbrush wash clean, the defective high-pressure oil pipe of effects on surface is carried out and is scrapped mark.
But, because high-pressure oil pipe length is longer, more carefully, dip solvent or diluent paint removal process with brush slow, and the hand-held high-pressure oil pipe of operator and brush, easily cause colliding with of high-pressure oil pipe, cause high-pressure oil pipe to use.
Summary of the invention
Technical problem to be solved by this invention is: the reproducing method providing a kind of high-pressure oil pipe, dips solvent or diluent paint removal process slowly to solve with brush, and the hand-held high-pressure oil pipe of operator and brush, easily cause the technical problem of colliding with of high-pressure oil pipe.
For solving the problems of the technologies described above, technical scheme of the present invention is: the reproducing method of high-pressure oil pipe, comprises the following steps implemented successively:
(1) high-pressure oil pipe dismantled is cleaned, removing high-pressure oil pipe surface greasy filth;
(2) some high-pressure oil pipes are put into sand-blasting machine, use soda ash as abrasive particle injection high-pressure oil pipe surface, removing high-pressure oil pipe surface paint and greasy dirt;
(3) soda ash of high-pressure oil pipe remained on surface is cleaned;
(4) cleaning fluid of high-pressure oil pipe remained on surface is blown off;
(5) check high-pressure oil pipe state, sort out high-pressure oil pipe in apparent good order and condition;
(6) inner cavity of high-pressure oil pipe that clean surface is in good condition, makes its cleannes reach requirement, sorts out the high-pressure oil pipe meeting again manufacture requirements;
(7) high-pressure oil pipe meeting again manufacture requirements is assembled into high-pressure oil pipe sub-assembly.
Improve as one, adopt the soda ash of spray process cleaning high-pressure oil pipe remained on surface.
After have employed technique scheme, the invention has the beneficial effects as follows: due to the reproducing method of high-pressure oil pipe, in step (2), some high-pressure oil pipes are put into sand-blasting machine, uses soda ash as abrasive particle injection high-pressure oil pipe surface, removing high-pressure oil pipe surface paint and greasy dirt, sandblasting mode compares the mode adopting brush to dip solvent or diluent paint removal, not only accelerate the cleaning speed on high-pressure oil pipe surface, thus improve the operating efficiency that high-pressure oil pipe manufactures again, improve cleaning effect; And colliding with of high-pressure oil pipe can not be caused, avoid high-pressure oil pipe and damage in manufacture process again; The mode of sandblasting simultaneously can be selected arbitrarily between different roughness, increases the adhesive ability of paint so that the high-pressure oil pipe after manufacturing again sprays paint during process; Adopt soda ash to carry out sandblasting as abrasive particle to high-pressure oil pipe, because soda ash is easy to cleaning, can not results in blockage to inner cavity of high-pressure oil pipe, be convenient to the carrying out of subsequent step.
Detailed description of the invention
In order to make object of the present invention, technical scheme and advantage clearly understand, below in conjunction with embodiment, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
The reproducing method of high-pressure oil pipe, comprises the following steps implemented successively:
(1) high-pressure oil pipe dismantled is cleaned, removing high-pressure oil pipe surface greasy filth;
(2) some high-pressure oil pipes are put into sand-blasting machine, use soda ash as abrasive particle injection high-pressure oil pipe surface, removing high-pressure oil pipe surface paint and greasy dirt;
(3) soda ash of spray process cleaning high-pressure oil pipe remained on surface is adopted;
(4) cleaning fluid of high-pressure oil pipe remained on surface is blown off;
(5) check high-pressure oil pipe state, sort out high-pressure oil pipe in apparent good order and condition, simultaneously for the defective high-pressure oil pipe in surface, carry out and scrap mark;
(6) inner cavity of high-pressure oil pipe that clean surface is in good condition, makes its cleannes reach requirement, sorts out the high-pressure oil pipe meeting again manufacture requirements, inside is had to the high-pressure oil pipe of blocking simultaneously, carries out and scrap mark;
(7) high-pressure oil pipe meeting again manufacture requirements is assembled into high-pressure oil pipe sub-assembly.
The reproducing method of the high-pressure oil pipe that the embodiment of the present invention provides, due in step (2), some high-pressure oil pipes are put into sand-blasting machine, use soda ash as abrasive particle injection high-pressure oil pipe surface, removing high-pressure oil pipe surface paint and greasy dirt, sandblasting mode compares the mode adopting brush to dip solvent or diluent paint removal, not only accelerates the cleaning speed on high-pressure oil pipe surface, thus improve the operating efficiency that high-pressure oil pipe manufactures again, improve cleaning effect; And colliding with of high-pressure oil pipe can not be caused, avoid high-pressure oil pipe and damage in manufacture process again; The mode of sandblasting simultaneously can be selected arbitrarily between different roughness, increases the adhesive ability of paint so that the high-pressure oil pipe after manufacturing again sprays paint during process; Adopting soda ash to carry out sandblasting as abrasive particle to high-pressure oil pipe, because soda ash is easy to cleaning, thus without the need to worrying that part soda ash enters inner cavity of high-pressure oil pipe, being convenient to the carrying out of subsequent step.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any amendments done within the spirit and principles in the present invention, equivalent replacement and improvement etc., all should be included within protection scope of the present invention.
