Lub nplhaib plua plav yog dab tsi? Lub pas nrig wiper foob metric yog lub foob reciprocating ntsia rau ntawm tus pas nrig piston kom tiv thaiv cov plua plav sab nraud los ntawm kev nkag mus rau lub tog raj kheej hydraulic.

Lub wiper foob muaj cov yam ntxwv ntawm kev hnav zoo, tiv thaiv extrusion, cuam tshuam tsis kam, me compression deformation, thiab yooj yim installation. Feem ntau siv nyob rau hauv hydraulic systems, tshuab cuab yeej, mining khoom, metallurgical khoom, txheem hydraulic cylinders, general mechanical khoom, thiab lwm yam.

Lub nplhaib plua plav yog ntsia rau hauv qhov zawj, thiab vim muaj qee qhov cuam tshuam ntawm daim di ncauj ntawm lub nplhaib plua plav thiab lub piston pas nrig, daim di ncauj ntawm lub nplhaib plua plav yog nruj nreem txuas rau saum npoo ntawm lub piston pas nrig.

Qws wiper foob rings yog qhov tseem ceeb heev rau kev tiv thaiv cov khoom siv hydraulic tseem ceeb. Yog tias cov khoom txawv teb chaws cuam tshuam, tsis yog tsuas yog cov khoom sib khi yuav hnav, tab sis kuj tseem hnav lub tes tsho thiab piston pas nrig. Cov impurities nkag mus rau hauv nruab nrab hydraulic tseem yuav cuam tshuam rau kev ua haujlwm ntawm lub valve thiab twj tso kua mis, thiab tuaj yeem ua rau cov khoom siv no puas. Lub nplhaib plua plav tuaj yeem tshem tawm cov plua plav ntawm qhov chaw ntawm lub piston pas nrig, tab sis nws yuav tsis ua rau cov roj zaj duab xis ntawm lub piston pas nrig, uas tseem muaj txiaj ntsig zoo rau lubrication ntawm cov khoom sib khi. Thaum tsim lub nplhaib plua plav, nws yuav tsum tsis tsuas yog hloov mus rau piston pas nrig, tab sis kuj ua lub luag haujlwm sib khi hauv qhov zawj.

Metric loj

Chav tsev ntawm qhov ntev nyob rau hauv Tuam Tshoj txais yuav lub thoob ntiaj teb chav tsev ntawm qhov ntev, lub "meter" (M), uas yog "metric" unit.

Qhov "metric system" yog kaum tsib, nrog 1 meter=10 decimeters (DM); 1 decimeter =10 cm (CM); 1 centimeter =10 millimeters (MM),

Hloov qhov Inch loj rau "metric" loj

1 nti =25.4 millimeters, uas yog "metric" loj.

Piv txwv li, 5/8 '' × 25.4=15.875 mm; 5/16'' × 25. {8}}.938 hli.
