Kev txhuam txhuam cov txheej txheem rau kev txhim kho piston pas nrig nto puas
Mar 15, 2020
1. Dianjing: Xaiv TGY-1 Dianjing, lub pas nrig piston txuas nrog rau qhov tsis zoo ncej (qhov zoo sib txuas) ntawm lub zog fais fab, thiab qhov hluav taws xob yog 10-14V rau 1030s. Lub hom phiaj ntawm Dianjing yog kom tshem tawm cov roj roj av. Tom qab ntxuav tas, yaug cov kua dej ua kua nyob rau saum npoo ntawm lub pas nrig piston nrog dej dawb.
2. Kev ua kom nrov: Siv THY-5 ua kom daws teeb meem. Txuas mus rau qhov zoo ncej ntawm lub zog muab hluav taws xob (rov qab txuas txuas), thiab muaj zog, qhov hluav taws xob yog 12-15V, lub sijhawm yog 10-30s. Nyob rau lub sijhawm no, lub ntsej muag ntawm lub pas nrig piston yog nyiaj-grey. Lub hom phiaj ntawm kev ua kom muaj zog yog tshem cov oxide zaj duab xis nyob rau saum npoo ntawm lub pas nrig piston.
3. Txhuam plating hauv qab txheej: tshwj xeeb nickel plating (TDY101), so tsis muaj hluav taws xob rau 3-5s. Cov pas nrig piston txuas nrog cov hluav taws xob tsis zoo (kev sib txuas zoo) ntawm lub zog hluav taws xob, thiab qhov hluav taws xob yog 15-18V. Kev ceev ceev ntawm lub cathode thiab anode yog 12-15m / min.
4. Txhuam cov plating ua hauj lwm txheej: siv cov npib tsib xee (TDY102), so tsis muaj hluav taws xob rau li 3-5s. Pist pas nrig txuas nrog qhov zoo electrode (thim rov qab sib txuas) ntawm lub zog hluav taws xob, thiab qhov hluav taws xob yog 15V. Kev ceev ceev ntawm lub cathode thiab anode yog 12-15m / min. Tshem tawm kev ntxhov siab. Ua kom muaj zog ntxiv. Thaum qhov kev puas tsuaj puv lawm, siv kab ntawv pleev xim hlau. Whetstone sanded nws saum npoo thiab clamped nws nrog ncig phau arc rau nrhiav kom tau roundness.
5. Txhuam plating kawg ua hauj lwm txheej: Lub pas nrig txuas nrog rau qhov zoo ntawm hluav taws xob (rov qab txuas) ntawm lub hwj huam, thiab qhov hluav taws xob yog 15V. Kev ceev ceev ntawm cathode thiab anode yog 12-15m / min. Chrome-plated alloy nrog chromium txheej tuab ntawm 3-5 μm.
6. Polishing: Siv lub log polishing los txhuam cov txheej txhuam txhuam kom nws qhov chaw saum npoo yog Ra-0.4 μm thiab qhov ntsuas qhov ntev ua tau raws li qhov yuav tsum ua.
