Portable diesel generators yuav tsum ua kom lub teeb yuag tsim thiab txav tau yooj yim thaum ua kom muaj zog ntawm cov qauv thiab kev ntseeg tau ntawm kev ua haujlwm. Kev xaiv cov ntaub ntawv yuav tsum muaj qhov sib npaug ntawm cov khoom siv kho tshuab, kev tiv thaiv ib puag ncig, thiab kev lag luam. Daim ntawv thov ntawm cov ntaub ntawv tseem ceeb ncaj qha txiav txim siab lub zog ntawm chav tsev, kev tiv thaiv corrosion, tshav kub dissipation efficiency, thiab tag nrho qhov hnyav, yog li ua lub luag haujlwm tseem ceeb hauv kev tsim thiab tsim khoom.
Lub casing thiab thav duab yog feem ntau yog ua los ntawm siab - zoo carbon structural steel los yog tsawg- alloy steel daim hlau. Cov hlau no muaj lub zog muaj zog thiab ruaj khov, muaj peev xwm tiv taus cov kev cuam tshuam thaum lub sij hawm thauj mus los thiab kev vibrations tsim thaum lub sij hawm ua haujlwm ntev -, thaum muab kev txhawb nqa ruaj khov rau cov khoom siv hluav taws xob thiab hluav taws xob. To balance corrosion resistance and aesthetics, the casing surface is often treated with phosphating, electrophoresis, or powder coating to form a dense protective layer, adapting to outdoor humid, salt spray, and dusty environments.
Cov khoom tseem ceeb ntawm lub cav diesel, xws li lub tog raj kheej thaiv, lub tog raj kheej lub taub hau, thiab crankshaft, feem ntau yog ua los ntawm siab - lub zog grey cam khwb cia hlau los yog hlau ductile. Grey cam khwb cia hlau muaj zoo hnav tsis kam, kev co damping zog, thiab casting processability, ua rau nws haum rau manufacturing complex, nyob ruaj ruaj qhov chaw. Ductile cam khwb cia hlau, ntawm qhov tod tes, excels ntawm lub zog thiab toughness thiab feem ntau yog siv nyob rau hauv crankshafts thiab txuas rods uas dais loj alternating loads, kom ntseeg tau tias lawv tsis yooj yim tawg nyob rau hauv siab - khiav ceev thiab cuam tshuam loads. Txhawm rau txhim kho qhov kub thiab txias tsis kam, alloy cam khwb cia hlau lossis cua sov- kho kom muaj zog yog siv rau qee qhov kub siab -.
Tsiv cov khoom xws li pistons thiab lub tog raj kheej liner feem ntau yog ua los ntawm aluminium alloys lossis alloy steel. Aluminium alloy pistons muaj thermal conductivity zoo thiab yog lub teeb yuag, txo qis reciprocating inertia thiab txhim kho lub cav teb ceev; alloy steel lub tog raj kheej liner undergone nitriding kev kho mob los txhim kho hardness thiab hnav tsis kam, ncua lawv cov kev pab cuam lub neej. Lub plunger thiab rab koob valve sib dhos hauv cov roj txhaj tshuaj feem ntau yog ua los ntawm siab -carbon chromium bearing steel lossis stainless hlau, muaj kev hnav zoo heev thiab kev tiv thaiv corrosion, kom ntseeg tau tias kev txhaj tshuaj raug thiab atomization zoo.
Nyob rau hauv seem generator, lub stator thiab rotor cores feem ntau yog ua los ntawm laminated siab -permeability silicon steel los xij kom txo tau eddy tam sim no poob thiab txhim kho efficiency. Cov winding conductors feem ntau yog tooj liab, vim lawv cov conductivity siab thiab muaj zog oxidation tsis kam, ua kom cov zis ruaj khov thiab txo cov hluav taws kub. Qee tus qauv qis- tus nqi qis yuav siv aluminium hlau windings, tab sis qhov no yuav tsum tau them nyiaj rau hauv qhov chaw hla - ntu ntu thiab tsim kom muaj cua sov.
Lub tshuab cua txias siv cov ntaub ntawv sib txawv nyob ntawm txoj kev ua kom txias: huab cua- cov qauv txias siv aluminium alloy lossis tooj liab cua sov dab dej, siv lawv cov thermal conductivity kom sai tshem tawm cov cua sov ntawm lub tog raj kheej; dej-cov qauv txias feem ntau siv cov txhuas lossis tooj liab corrugated tiaj tus rau cov tub ntxhais radiator, ua ke nrog siab -cov roj hmab hoses kub thiab cov tshuaj tua kab mob ua kom sov, ua kom tau txais txiaj ntsig zoo ntawm kev sib pauv cua sov thiab kev tiv thaiv corrosion.
Ntawm cov khoom siv pabcuam, cov roj tank feem ntau yog ua los ntawm siab - ntom polyethylene lossis steel phaj nrog rau sab hauv los tiv thaiv- txheej txheej. Lub qub yog lub teeb yuag thiab xau- pov thawj, thaum lub tom kawg muaj lub zog siab thiab zoo hluav taws kub. Lub vaj huam sib luag tswj vaj huam sib luag feem ntau siv ABS lossis PC engineering yas, uas sib txuas cov rwb thaiv tsev, huab cua tsis kam, thiab molding yooj.
Hauv cov ntsiab lus, cov ntaub ntawv tseem ceeb siv nyob rau hauv lub tshuab hluav taws xob portable muaj xws li cov qauv hlau, cam khwb cia hlau, aluminium alloy, tooj liab, silicon steel, thiab engineering plastics. Cov ntaub ntawv no tau raug teeb tsa raws li kev xav tau sib txawv rau kev ntxhov siab, thermal conductivity, corrosion resistance, thiab lightweighting. Kev sib xyaw ua ke ntawm kev xaiv cov khoom siv tshawb fawb thiab cov txheej txheem tsim khoom zoo ua kom ntseeg tau tias lub tshuab hluav taws xob teeb tsa, thaum tswj kev txav mus los, tseem muaj lub zog txaus, ruaj khov, thiab kev hloov pauv ib puag ncig, muab cov khoom siv txhim khu kev qha rau ntau yam khoom siv hluav taws xob ib ntus thiab xwm txheej ceev.
