2、in view of the hydraulic system installment proposed a series of concrete measures, by achieves in the construction process the contamination control.榀鲆塔猝时缛遂鳏肉吡Key words: Hydraulic system; Contamination control; Installment肉菊捕掏缵认矾嵬伸索1 outline墨縻贷舜汛谗瘭淮懵牧The hydraulic transmission technology is born af

3、ter 18th century namely obtains the swift and violent development. Today, the hydraulic transmission equipment obtains the widespread application in all the various trades and occupations, manifests especially on the modernized large-scale production line fully. The horse steel hot rolling H section

4、 production line, hydraulic fluid tank volume 54 kL, oil motor 38, each kind of specification hydraulic cylinder reaches 717, only the hydraulic pressure pipeline long reaches more than 20,000 rice.忄恙煎榕帕侨茈褪柳付The hydraulic transmission technology has its incomparable merit, this is it can the swift a

5、nd violent development main reason, at the same time, the hydraulic transmission equipment also has its frail one side, anti- pollution ability is low is the prominent weakness. According to the pertinent data record, the hydraulic pressure breakdown has 70% 80% is causes by the fat liquor pollution

6、. Must guarantee hydraulic system normal, reliable movement, must have to maintain the system clean.茧坭唳浼莹漂陪颧储酐2 systems pollution harm and reason绞贿蜴未提邾炯搿炝凹After the pollutant mixes in the system to be able to accelerate the hydraulic pressure components attrition, grinds damages, the burn even destr

7、oys or causes the valve movement to malfunction or to cause the noise. The pollutant can stop up the hydraulic pressure part the throttle or the throttle slit, the change hydraulic system operating performance, causes the movement to be out of balance even completely malfunctions, has the misoperati

8、on to create the accident. The dust pellet can accelerate the seal damage in the hydraulic cylinder, the cylinder tube internal surface pulling injury, causes to divulge increases, the thrust force insufficiency or the movement are unstable, crawling, the speed drops, has the unusual sound and the v

9、ibration. Also possibly causes the mesh to stop up, the hydraulic pump blots the difficulty, the oil discharge is impeded but has the cavitation, the vibration and the noise, stops up seriously when can oversized but penetrate because of the resistance the mesh, loses completely filters the function

10、, creates the hydraulic system the vicious circle.昭辊叻幽丕黧萍竟蹁鲱The system pollution reason are very many, produces the mechanism from the pollution to look, divides into 2 kinds: (1) manufactures, in the installation process ambushs in system pollutant. (2) in the system work process produces pollution

11、. Obviously, the system manufacture, in the installation process ambushs pollutant many for the scrap, the burr, the molding sand, the coating, the grinding compound, welds solid particle and so on the dregs, rust piece and dust, they the harm quite are big to the system, must strengthen the managem

12、ent in this stage, the control pollution, after guarantees the installment the hydraulic system to be able safely reliably to move.艮鳆查绰窘匿吐鹂莴堕3 hydraulic systems manufacture, installment contamination control犀洁莜厩姗芄邦读獗搴3.1 hydraulic pressure components processing contamination control踪彬嫉病筮霾够圪山裤The hyd

31、se steel hot rolling H section hydraulic pressure pipeline long reaches more than 20,000 rice, but the pipelining also is easy to be polluted the work, therefore, the hydraulic pressure pipeline contamination control is an important content which the hydraulic system maintains cleanliness.数燠脬锬触悠株洹揩处

32、Before the pipelining must clean up the internal big pellet impurity, forbid in the tube keep absolutely the stone, sundry goods and so on rags. Pipelining in the process if has the long time the severance, must promptly seal the orifice to prevent the sundry goods invasion. In order to prevent weld

33、s the dregs, oxidizes the iron-covered invasion system, suggested the pipeline welding uses the shielded welding like argon arc welding.堡阢藿獭醴榘跤亻沧绲After the pipelining finished, after must pass through the pipeline acid pickling, the system flushing only then merges the system as a system part. Forbi

43、 then in the explanation fat liquor includes the massive moisture contents. 苓掊在逮蒎脾霆爬迹枨(2) combustion method: With pure, the dry cotton yarn or the cotton paper moisten little treats the examination the fat liquor, then lights with the fire it. If discovered “pi pa blasts open the sound or the flash

44、phenomenon, then in the explanation fat liquor includes many moisture contents. 硭瞠寸嗵酆铺儡统偶仙4.2 hydraulic fluids foreign inclusion distinction 瓴卫郢芮液踉粘骸蒉埒(1) feeling view distinction: In the fat liquor has the obvious metal pellet suspension, twists with the finger pinches when feels directly to the ti

46、tinction: May put in purely, in directly the dry test tube regarding the viscosity low hydraulic fluid heats up the elevation of temperature. If discovered in the test tube the fat liquor appears the precipitation or the suspension, then in the explanation fat liquor included the mechanical impurity

47、. 觫鳜郄杩樯歙菝谀究曩(3) filter paper distinction: Regarding the viscosity high hydraulic fluid, after may use the pure gasoline dilution, then uses the clean filter paper to carry on filters. If discovered on the filter paper preserves the massive mechanical impurity (metal powder), then the explanation hyd

48、raulic pressure part seriously wore. 陂伎贾臆莉多卅甬纥軎(4) sound distinction: If the entire hydraulic system has big, the off and on noise and the vibration, at the same time the main oil pump sends out humming sound sound, even appears the connecting rod crawling the phenomenon, observed the fuel tank liqu

49、id level by now, the drill tubing exportation or the transparent liquidometer, could discover the massive froths. This kind of situation showed the hydraulic fluid has plunged the massive air. 些彝聚消歃避放联咕徽4.3 hydraulic fluids viscosity change distinction 蛹踔攵币囤罂昂普膀葩1) glass plate tilter: Takes together

50、 the clean glass plate, its level laying aside, and was measured a hydraulic pressure oil dripping drop on the glass, at the same time drops drop of standard hydraulic fluid again in side (same trademark new product hydraulic fluid), then inclines the glass plate, and attention observation: If were

51、measured the fat liquor the speed of flow and mobile is away from compared to the standard fat liquor big, then explains its ratio of viscosities standard fat liquor low, otherwise, then explained its ratio of viscosities standard fat liquor is high. 虹鬲膺嵛镝书墒涪沆璋2) glass jar inversion law: The hydraul

52、ic pressure fat liquor and the standard fat liquor which measured distinguishes abundantly (do not have to install too fully) in two sizes and the length same clear-glass bottle, again uses the plug to block two bottle mouths. Two bottles lays aside abreast in row in together, then at the same time

53、rapidly two bottles of inversions. If were measured the hydraulic fluid rises quickly in bottle air bubble compared to the standard fat liquor in bottle air bubble, then explanation fat liquor ratio of viscosities standard fat liquor viscosity low, otherwise, then the showing fat liquor ratio of vis

54、cosities standard fat liquor viscosity is high; If two kind of fat liquors air bubbles rise speed approaches, then the showing viscosity is also similar.湄诒筛帆陵刺蜮搓憨鞫4.4 hydraulic fluids mass variation distinction 茨胩跪蠃饥寡濂枇肆蚊1) oil pump fat liquor distinction: Takes out little from the oil pump is measu

55、red the fat liquor, if discovered its has assumed the cream color muddy shape (sometimes to like faint yellow milk), when also with combustion method distinction, discovered it contains the massive moisture contents, has lost the coherency with feel sense, then explained this fat liquor emulsified t

56、he deterioration thoroughly, not suitable uses again. 狂嗄猊噔瑭爷散砟埋莒2) fuel tank fat liquor distinction: Takes out little from the fuel tank is measured the fat liquor, filters with the filter paper, if on the filter paper preserves has the black residual, also has the unusual smell which irritates the

57、nose, then explains this fat liquor already oxidative rancidity, also may take out the partial precipitations greasy dirt directly from the fuel tank base, if discovered has many asphalt and the sol precipitates, places it on the finger to twist pinches, if felt to sol many, the adherency is strong,

58、 then explains this oil already oxidative rancidity. 脸馋合舜窈橱癫鹾男湖5 Summary于司瓦壁翅施啵毗骄窨The hydraulic system contamination control passes through in the entire construction process, requests the operator each step all to have to consider to maintains cleanliness the measure, maximum limit reduces the syst
