Overview in all course canal assembly regards high-pressured hydraulic as harbour can component, in diesel engine high pressure there is main effect in rail system in all. In all the working principle of course canal assembly is shown 1 times like the graph, in all the high-pressured fuel that course canal provides oil feed pump allocates each fuel injector in, harbour is pressed since implement action. Accordingly, to make whole in all rail system can work reliably normally, in all course canal assembly must satisfy taller cleanness to spend a requirement. However, in all a narrow passage providing the only means of access to a certain place of course canal lumen is complex and much more long and thin aperture, cleanness spends control is one needs captured difficulty technology all the time, if in all the cleanness that course is in charge of is spent cannot get assure, foreign matter grain will enter assembly of each fuel injector together along with high-pressured fuel in, serious when can appear even occasionally block dead phenomenon, bring about engine to cannot work normally, affect the dependability of engine and security. Graph 1 in all principle of work of course canal assembly pursues accordingly, good to solve in all course Guan Qingjie spends a question, one steam of Chinese does not have stannic oil pump oily institute is united in wedlock " electronic-controlled in all production technology of system of course derv spray and the research and development that the key equips and application " task, developed research technically to this. In all course canal cleanness spends case study " cleanness is spent " it is the degree that shows spare parts, assembly and overall and specific place are polluted by foreign matter. To this, the method that should use a provision collects foreign matter particle from formulary place. Generally speaking, the quantity of contamination includes: Phyletic, appearance, dimension, amount, weight and distributinging chroma measure index, specific with why to plant index, depend on the requirement that different contamination pledges to the product the influence degree of the quantity and cleanness spend control precision. What say here " formulary place " it is to point to what the product identifies and set, endanger product reliability refer in particular to place. What say here " foreign matter " include: Products plan, make, pack, carry, the itself in use and maintaining a course remains, the arises with systematic oneself whole foreign matter of outside interfuse. The product is be assembled through equipment treatment by the spare parts and become, so cleanness is spent cent is spent for spare parts cleanness and product cleanness is spent. Product cleanness is spent besides spend with spare parts cleanness outside having immediate concern, still reach personnel and evaluation to detect with facilities of manufacturing process, environment, production the method has affinity. Task group is main with some model in all course canal is test sample, plant to this in all the cleanness of course canal assembly spends control to reach among go burr and cleaned craft to undertake study, popularize those who make then in all course canal. Analysis in all impurity of course canal assembly basically forms by the following respects: 1.

The burr after the spare parts is machined clears not complete; 2.

Cutting fluid is cleaned sordid, cause course to be in charge of assembly pollution; 3.

Component did not adopt reliable preventive measure in process of keep in storage. In all cleanness of content of course canal grain is spent detect method in all course is in charge of assembly to clean extractive process is to use low pressure (pressure ≤ 4.

0bar and but the hand is moved adjust) clean defecate lotion from in all the mouth receiving oil of course canal assembly is entered, the course is pulsatile after cleaning, be poured out of by current limliting a powerful person and smoke filter in time to reclaim, clean pressure and the negative pressure that take filter to all pass gas to come true to liquid control. 1.

Sampling place and method in all place of course canal sampling is all lumen. 2.

Clean extractive condition (1) filter component: Film of filter of nylon of small hole of 5 μ M, diametical φ 47mm. (2) clear lotion: The school pump that accords with GB/T 8029-1987 regulation is oily. 3.

Implemental, device and equipment (1) flat head does not have tine forceps, desiccator and metage bottle. (2) analytic balance (0.

1mg) , precision is 3 class. (3) sweatbox of electric heat constant temperature. (4) granularity analyzer. (5) assembly of oil feed pump cleans extractive testing stand. 4.

Preparation works (1) detect the blame of the product that be measured the surface is cleaned clean. (2) with forceps clip takes filter film, 10min immerses in putting clean school pump oil first, in taking out park metage bottle next, reopen lid is put already warmed up to 160 ℃ ± the electric heat constant temperature of 5 ℃ rouses wind sweatbox in, stoving 60min, be taken out and put in time good top is built inside desiccator, say to weigh after cooling 30min (empty weight) . Every say to film of a piece of filter is put in measuring flask, filter film should say to weigh via two drying, it is with the 2nd metage accurate (the poor value of two drying metage is more than 0.

3mg) . 5.

In all course is in charge of clean extraction (1) will in all course canal installation is cleaning extractive testing stand to go up, in installing a process, avoid to join pipeline is polluted. (2) setting in all the means that course canal cleans is cleaned for pulsatile ration, pulsatile cycle is 12s, mensurable 5L. (3) the filter film after be being handled to smoke filter place to change. (4) enter in all course canal cleans extractive program, undertake cleaning extraction. (5) clean after smoking filter, in using forceps to move filter film to corresponding metage Min, wait for stoving to say to weigh. 6.

In all course canal cleanness spent assess task group to use grain law to detect with say serious way detects the method that is united in wedlock, among them, say serious way provides the basis that contaminant analyses, and the distributinging case that grain law can provide contaminative grain. Standard of comparison, OK and affirmatory cleanness spends grade. Watch 1 it is right some model in all the cleanness that course is in charge of is spent selective examination result. To above two batch produce after the treatment technology that course provides undertakes survey, discover in all, bring about in all cleanness of course canal assembly spends not the main reason of beautiful depends on: On one hand, each aperture intersects because place is gotten cut treatment to be able to produce flange burr; On the other hand, as a result of the treatment of whorl of aperture of the whorl inside each craft all is tap private plane to be formed in treatment of the tap on bottom outlet, and cut bits all be discontinuous metallic grain, in while these grain often are machining whorl, be being squashed to enter whorl. Above grain of two kinds of burr is common clean cannot effective purify, accordingly, the method purify that task group uses high pressure to clean these two kinds of burr. Nextpage in all cleanness of course canal high pressure spends control technology 1.

Clamping apparatus design is shown 2 times like the graph for clamping apparatus of cradle type circumgyrate, it installs clip to be able to be cleaned in all course is in charge of all outside faces to reach in aperture. Area of outside cover dead band is less than 15% . Graph clamping apparatus of circumgyrate of 2 cradles type 2.

If the graph is shown 3 times,nozzle is designed, 3 nozzle, among them two give nozzle to be used at continuously in all course is in charge of what outside face reachs whorl to clean, a L nozzle is used at in all the Kong Qing in course canal is washed. Graph 3 straight model with L nozzle 3.

Group of task of clear lotion choice is washed to a lot of Qing Dynasty the agent undertook experimenting evaluating, among them, masite 9106 with DANCO SV630 integral performance conspicuous. The contrast of these two kinds of clear lotion sees a table 2, DANCO SV630 is mixed in cost environmental protection respect is more exceedingly good. 4.

Parameter set cleans pressure 500bar, clean discharge 15L/min. 5.

Machine tool design and make be based on afore-mentioned requirements, task group designed cleaning machine of 500bar high pressure (if pursue,4 are shown) . This cleaning machine can finish pair of course to be in charge of surface of inside and outside and whorl part to undertake high pressure is rinsed and blow the craft such as dry, drying. This equipment has pressure tall, flexible security is good, good with automation degree advanced characteristic. Graph 4 " electronic-controlled in all production technology of system of course derv spray and the research and development that the key equips and application " the high-pressured cleaning machine that the task develops 6.

High pressure cleans experiment and result to detect the analysis is expressed 3 it is the cleanness that course canal has sampling observation and obtains after be being cleaned to passing cleaning machine of AHG-500 high pressure in all spend a result. Data analysis makes clear, each cleanness spends index to be able to satisfy a requirement completely already. Summary serves as communal oil duct and the high pressure of equipment of high-pressured harbour look in all course canal, it is high pressure in all the main component of rail system, and remain is in in all the contaminant in course canal is to affect whole high pressure in all the main factor of course fuel system. Accordingly, control in all the cleanness that course is in charge of is spent crucial. From the point of conventional machining technology and its mechanism, if whole process did not go scientificly,burr is reached clean craft, produce character to measure basic not be in a position to mention. The member that the project is comprised is united in wedlock " electronic-controlled in all production technology of system of course derv spray and the research and development that the key equips and application " the equipment of high-pressured cleaning machine that the task designs, the structure is simple, the operation is convenient, manufacturing efficiency is tall. Pass reasonable nozzle design and pressure, flow control, going won't be opposite in burr process in all the exterior quality that course provides and precision generation influence. In addition, because working medium is water, after be being handled through filtering, can use circularly, economic benefits is accordingly good, ensured in all the qualification that course is in charge of spare parts and assembly cleanness to spend quality.
