Description
Technical field
A kind of processing method of the application in relation to oil injector body is surface-treated especially for environmental-friendly oil injector body
Method.
Background technique
Fuel injector is for high pressure fuel injection is entered the indoor important component of burning, and its in fuel injection system
Working environment is generally difficult to control, in order to prevent oil injector body surface oxidisation, needs to carry out antirust treatment to oil injector body surface.
During manufacturing or transporting oil injector body, there can be many greases on oil injector body, and when carrying out antirust treatment, this
A little lipid phases need to remove clean.Moreover, cannot need to be dried there are liquid on oil injector body surface.Dry
After dry processing, then surface rust protection processing is carried out to oil injector body.
The mode that tradition is surface-treated oil injector body is as shown in Figure 1, in step 10, use liquid medium pair
Oil injector body surface carries out precleaning, in a step 11, carries out ungrease treatment, however, rinse step is carried out in step 12, it will
Oil injector body surface is tentatively rinsed, and rinsing is further carried out in step 13, however, because the oil spout in rinse cycle
Body surface has many water, needs to be dried at step 14.In this way, the surface cleaning for oil injector body walks
It is rapid to complete, surface spraying process is then carried out again.
Using aforesaid way, there is the shortcomings that not can avoid very much.Firstly, it is unfriendly to environment, need to generate a large amount of
Chemical sewage pollutes environment.Secondly, impurity contained in liquid will increase the possibility that oil injector body surface is secondary polluted,
And be not intended to inside oil injector body the position being surface-treated also inevitably be infected with part liquid.Moreover, above-mentioned
Processing mode step is excessive, complicated for operation.
Therefore, it is necessary to a kind of environment amenable oil injector body surface treatment methods.
Summary of the invention
The application's is designed to provide a kind of environment amenable oil injector body surface treatment method.
The application provides a kind of oil injector body surface treatment method, includes the following steps,
The first step, surface cleaning, for removing the grease of fuel injector surface attachment, extremely by the dry ice blasting of fragmentation
Oil injector body surface；
Second step, surface spraying process spray Aluminum Coating to the oil injector body after cleaning.
Preferably, diameter is 0.1--0.2mm after the dry ice fragmentation.
Preferably, the dry ice is using blast injection in oil injector body surface.
Preferably, the dry-ice temperature is at -80 DEG C or so.
Preferably, the surface spraying process includes the roughening treatment carried out to oil injector body surface.
Preferably, in the surface spraying process, the zinc-aluminium thin slice after fragmentation is sprayed using chemical dilution agent to oil spout
Body surface.
Preferably, the Aluminum Coating with a thickness of 6-16 μm.
Preferably, described that curing process step is carried out after the spraying process of surface.
Preferably, wear-resistant layer is further sprayed after the surface spraying process.
Using surface treatment method provided herein, it can be convenient and quickly oil injector body surface is handled,
Other pollutions will not be generated in the process, and environmentally friendly.
Detailed description of the invention
The exemplary embodiment of the application is described in detail below with reference to the accompanying drawings, it should be understood that described below
Embodiment be only used for explain the application, without being restricted to scope of the present application, appended attached drawing wherein:
Fig. 1 is the flow chart of oil injector body surface treatment method in the prior art.
Fig. 2 is the flow chart of one embodiment of oil injector body surface treatment method in the application.
Specific embodiment
In different drawings, the same or similar component is presented with like reference characters.
It should be appreciated that attached drawing is only used for being illustrated the application, the wherein size, proportionate relationship of component and component
Number is not as the limitation to the application.
It please refers to shown in Fig. 2, is the flow chart of the oil injector body surface treatment method of the application.In 20 steps first,
Surface cleaning is carried out, the purpose of this step is the grease for removing the attachment of oil injector body surface, and method is by the dry of fragmentation
Ice passes through spraying high-pressure gas to oil injector body surface.The temperature of the dry ice is controlled at -80 DEG C or so, and dry ice is broken into diameter
The particle of about 0.1-0.2mm.After surface cleaning, surface spraying process 21 is carried out, the purpose is in fuel injector body surface
Face forms Aluminum Coating of the thickness between 6-16 μm.In the present embodiment, surface spraying process includes for fuel injector body surface
The step 211 that face is roughened, so that the roughened layer for being less than 1um is formed on oil injector body surface, to increase Aluminum Coating
Adhesive force.Certainly, in other embodiments, roughing in surface step can be omitted.
In the spraying process of surface, by the way that the zinc-aluminium thin slice after fragmentation to be placed in chemical dilution agent, it is then sprayed into oil spout
The mode on body surface carries out, and in the present embodiment, the ingredient of chemical dilution agent is that petroleum adds hydrogen light fraction and n-butanol.
After the spraying process of surface, setting spraying wear-resistant layer step 22 forms the wear-resistant layer of 0.1-0.2mm, into one
Step protection Aluminum Coating.Certainly, in other embodiments, which can be omitted.
Finally, carrying out curing process step, curing process is carried out for oil injector body surface.
When the dry ice of fragmentation is sprayed by pressure-air to oil injector body, since the temperature of dry ice is -80 DEG C or so, institute
It can be distilled rapidly with encountering oil injector body, absorb a large amount of heat, so that oil injector body surface temperature is dropped to -20 DEG C or so, it is attached
In oil injector body surface grease can solidification and embrittlement.High speed impact and come dry ice particles can it be smashed and be removed.
In addition, dry ice is encountering fuel injector surface of the temperature much higher than it, during distillation, volume can be expanded to rapidly 500-
700 times, the function of similar microburst forms shock wave, and the grease and other impurity for being attached to oil injector body surface is removed.
After carrying out surface cleaning using dry ice, because any liquid is not used during clean, and
Even if the liquid any on oil injector body surface contamination in other techniques, also due to temperature freeze and it is clear
It is clean, so not needing drying steps, and after surface cleaning, it can directly carry out surface spraying process.It can not only save
The operating time is saved, and can prevent from being contaminated again in conventional procedures.
The application is described only in conjunction with the most practical preferred embodiment being presently considered above, it is to be understood that
Above description is not the limitation to the application, and the application is also not limited to the example above, the ordinary skill people of the art
The variations, modifications, additions or substitutions that member is made in the essential scope of the application, also should belong to the protection scope of the application.
