CK 45 Steel Precision Chromed Piston Qws yog ib qho tseem ceeb ntawm cov tub yees compressor, thiab nws cov kev sib luag thiab cov kev xav tau ntawm lub zog yog siab heev. Piv txwv li, ib tug piston pas nrig muaj ib txoj kab uas hla ntawm 63.5mm thiab ib tug ntev ntawm 630mm, thiab lub cylindricity yog teev raws li φ0.018mm. Qhov saum npoo ntawm lub tog raj kheej yuav tsum tau hnav-tiv taus, thiab lub zog saum npoo yuav tsum muaj ntau dua lossis sib npaug li 50HRC. Nyob rau hauv cov nqe lus ntawm kev siv tshuab, high-frequency quenching feem ntau yog siv.
1. Siv 2 daim V-shaped hlau los txhawb ob sab ntawm tus pas nrig piston, tig lub piston pas nrig nrog koj txhais tes rau ntawm qhov taw qhia sab hauv ntawm nruab nrab thav duab, sau cov nqi co ntawm tus pas nrig piston, thiab kos lub siab thiab qis cov ntsiab lus ntawm tus pas nrig.
2. Siv tus pin bolts los nias rau ntawm qhov siab ntawm 5-11 hli, kom nws nyob twj ywm, thiab tuav tus ncej nrog ib tug pas nrig tooj liab ob peb zaug kom muaj kev ntxhov siab. Lub zog ntawm tus pas nrig tooj liab yog 130-160HB, thiab lub zog ntawm tus pas nrig yog 280-300HB. Vim hais tias tus pas nrig tooj liab yog softer dua li piston pas nrig, qhov saum npoo ntawm tus pas nrig piston tsis yooj yim deformed thaum nws yog khob.
3. Tshem tawm tus pin, thiab xyuas qhov kev vibration ntawm lub piston pas nrig dua raws li daim duab 1. Yog tias qhov kev vibration siab tshaj tus qauv, nws tuaj yeem ncaj dua kom txog thaum nws ncav cuag tus qauv. Lub sijhawm no, yuav tsum ua siab ntev thiab ua haujlwm zoo.
