Ck45 Hard Chrome Plated Piston Qws

Xa kev nug

Hauj lwm lawm

Lub CK45 Hard Chrome Plated Piston Qws yog qhov siab -kev ua tau zoo tsim los rau hydraulic lub tog raj kheej daim ntaub ntawv, muab cov kav ntev, corrosion kuj, thiab txhim khu kev qha ua haujlwm raws li qhov xav tau. Ua los ntawm CK45 steel- nruab nrab carbon steel qib sib npaug rau AISI 1045-piston pas nrig no ua ke cov khoom siv kho tshuab zoo heev nrog rau qhov zoo tshaj plaws.
Cov pas nrig tau dhau los ua cov txheej txheem nyuaj chrome plating, ua rau cov txheej txheem chrome nrog qhov tsawg kawg nkaus thickness ntawm 20 microns thiab hardness tshaj 800 HV. Qhov no txhim khu kev hnav tsis kam thiab muab kev tiv thaiv corrosion. Qhov saum npoo roughness yog khaws cia ntawm Ra Tsawg dua lossis sib npaug ntawm 0.2 μm, kom ntseeg tau tias kev ua haujlwm du thiab txo kev sib txhuam. Dimensional raug yog guaranteed nrog ISO f7 kam rau ua, roundness nyob rau hauv 50% ntawm txoj kab uas hla kam rau ua, thiab straightness txwv rau 0.2 hli ib 'meter'.

CK45 cov khoom muaj lub zog tensile tsawg kawg yog 580 MPa thiab lub zog tawm los ntawm 350 MPa, nrog elongation tshaj 15%, muab qhov zoo toughness thiab qaug zog. Cov kev xaiv muaj xws li tawv chrome plating, quenching thiab tempering, induction hardening, los yog ua ke kev kho mob, ua rau nws hloov mus rau ntau yam kev lag luam.

Cov piston pas nrig no feem ntau muab nyob rau hauv qhov ntev txog li 9 meters, nrog rau txoj kab uas hla ntawm 40 hli mus rau 320 hli. Txhua tus pas nrig yog coated nrog anti- xeb roj thiab ntim rau hauv cov ntawv thiab ntoo rooj plaub kom muaj kev tiv thaiv thaum khaws cia thiab kev thauj mus los.

Zoo tagnrho rau cov tshuab hydraulic hauv kev tsim kho, kev tsim khoom, thiab cov tshuab hnyav, CK45 Hard Chrome Plated Piston Qws muab kev ua tau zoo, kev ua haujlwm ntev, thiab kev ntseeg tau.
