Kev ntsuas kev ua neej nyob ntawm qhov kub khiav ntau- kab noj hniav pwm yuav tsum muaj kev xav txog ntau qhov ntev, nrog rau cov khoom siv, kev tsim qauv, kev ua haujlwm, thiab qib kev saib xyuas. Kev ntsuas lub neej nrawm, hauv - kev saib xyuas qhov chaw, thiab ntau- qhov ntsuas qhov ntsuas hla - siv tau los ua kev tshawb fawb kwv yees qhov tseem tshuav ntawm cov nyiaj stamping. Cov qauv kev ntsuas tseem ceeb tam sim no tuaj yeem tswj qhov kev kwv yees kev ua neej nyob hauv ± 15%.
1. Kev ntsuas qhov tseem ceeb thiab qhov ntsuas
(1) Pwm Khoom Khoom
Hardness thiab Wear Resistance: Lub hardness saum npoo ntawm qhov tseem ceeb (xws li kub nozzles thiab manifolds) yuav tsum siab tshaj los yog sib npaug rau HRC55, thiab cov txheej roughness Ra tsawg dua los yog sib npaug rau 0.2μm, ncaj qha cuam tshuam rau hnav tsis kam.
Thermal Stability thiab Fatigue Resistance: Cov khoom yuav tsum muaj ib tug tsawg coefficient ntawm thermal expansion thiab siab thermal conductivity kom txo thermal kev nyuaj siab tsub kom thiab ncua kev pib ntawm thermal qaug zog tawg.
(2) Kev tsim qauv tsim kev sib haum xeeb
Stress Concentration Factor: Los ntawm finite element simulation los tsim cov huab maps, qhov kev nyuaj siab concentration cheeb tsam ntawm lub parting nto ntug yuav tsum tsawg tshaj li 1.8 npaug ntawm kev nyab xeeb pib; txwv tsis pub, thaum ntxov cracking yuav tshwm sim. Txias / cua sov System Layout: Qhov zoo tshaj plaws ntawm cov cua sov thiab cov kav dej txias yog 4 nrog ib txoj kab uas hla ntawm 6 hli, uas txo qhov siab tshaj qhov sib npaug thaum tswj cov cua sov ua haujlwm.
Flow Channel Balance: Cov ceg ntev sib txawv ntawm H-hom lossis X- hom manifolds yuav tsum tsawg dua lossis sib npaug li 5 hli, thiab txoj kab uas hla qhov yuam kev tsawg dua lossis sib npaug li 0.1 hli, ua kom muaj kev sib xyaw ua ke ntawm txhua kab noj hniav thiab tsis txhob muaj kev sib tsoo hauv zos.
(3) Kev tsim khoom thiab kev kho cua sov
Forging thiab Machining Accuracy: Tsim nyog forging piv kom tsis txhob muaj cov qauv fiber ntau ua rau txo qis kev sib hloov txhua yam khoom; positioning nplhaib kam rau ua H7 / js6, coaxiality Tsawg dua los yog sib npaug rau 0.02mm.
Kev kho cua sov zoo: Nqus quenching + sib sib zog nqus cryogenic kho kom txhim kho microstructure uniformity; nitriding los yog laser quenching kom ntxiv dag zog rau saum npoo thiab ntev lub neej qaug zog.
(4) Kev siv thiab kev saib xyuas
Kev khiav hauj lwm ib puag ncig Parameters: Kub hloov pauv, txhaj tshuaj siab, thiab lubrication tej yam kev mob cuam tshuam ncaj qha rau tus nqi hnav. Thermo-txheej txheem coupling cuam tshuam yuav tsum tau soj ntsuam kom meej nyob rau hauv siab - kub. Kev ua haujlwm tau zoo thiab kev saib xyuas tsis tu ncua: zam kev puas tsuaj los ntawm kev ua haujlwm tsis raug; tsis tu ncua ntxuav cov ntws raws, tshuaj xyuas cov khoom hnav, thiab hloov cov khoom puas yooj yim xws li cua sov coils thiab thermocouples kom raws sijhawm.
