Diesel generator teeb lub suab nrov daws teeb meem

Lub tshuab hluav taws xob diesel yog ib qho khoom siv hluav taws xob sib xyaw ua ke uas hloov cov hluav taws xob ntawm cov roj rau hauv hluav taws xob hluav taws xob. Nrog rau kev loj hlob ntawm kev lag luam hauv computer thiab kev sib txuas lus, qhov kev thov rau cov khoom siv hluav taws xob txhim khu kev qha los ntawm cov khoom siv kuj nce ntxiv. Vim muaj teeb meem ntawm lub sijhawm siv hluav taws xob hauv UPS fais fab mov, cov tshuab hluav taws xob diesel muaj qhov chaw loj hlob. Txawm li cas los xij, thaum lub tshuab hluav taws xob diesel muab kev yooj yim rau tib neeg, lawv lub suab nrov (lub tshuab hluav taws xob diesel teeb lub suab nrov) thiab emissions kuj cuam tshuam rau peb qhov chaw nyob, tshwj xeeb tshaj yog lub suab nrov ntawm lub tshuab hluav taws xob teeb ncaj qha cuam tshuam rau tib neeg txoj haujlwm thiab lub neej. Raws li tib neeg cov kev cai ib puag ncig maj mam nce, yuav ua li cas daws thiab kov yeej cov teeb meem saum toj no tau dhau los ua tus yuam sij rau kev thov thiab kev txhim kho ntawm cov tshuab hluav taws xob diesel. Ntawm no, peb yuav tsom mus rau kev qhia txog qhov tshwm sim thiab kev daws teeb meem ntawm lub suab nrov hauv cov tshuab hluav taws xob diesel.

1. Cov pa pa tawm suab nrov ntawm lub tshuab hluav taws xob teeb

Cov pa pa tawm suab nrov yog ib hom kev kub ceev thiab siab ceev pulsating airflow suab nrov, uas yog lub zog tshaj plaws thiab tsim ib feem ntawm lub cav suab nrov. Nws yog ntau dua li cov suab nrov nrov thiab cov suab nrov ntawm lub tshuab hluav taws xob los ntawm lub cav lub cev, thiab yog qhov tseem ceeb tshaj plaws ntawm tag nrho cov suab nrov ntawm lub cav. Nws qhov tseem ceeb zaus yog lub cav hluav taws xob ntau zaus. Cov khoom tseem ceeb ntawm cov pa pa tawm suab nrov muaj xws li cov suab nrov tsawg zaus tshwm sim los ntawm cov pa pa tawm ib ntus, cov pa roj carbon resonance suab nrov hauv cov pa luam yeeb, Helmholtz resonance suab nrov hauv lub tog raj kheej, suab nrov tsim los ntawm cov cua kub ceev dhau los ntawm qhov khoob ntawm lub valve thiab cov kav dej tortuous, eddy. Cov suab nrov tam sim no, thiab cov suab nrov tsim tawm los ntawm cov pa hluav taws xob hauv qab lub zog yoj excitation hauv cov kav dej. Raws li qhov airflow ceev nce, qhov zaus ntawm lub suab nrov nce.

2. Mechanical suab nrov ntawm diesel generators

Mechanical suab nrov feem ntau yog hais txog kev vibration lossis kev sib nrig sib cuam tshuam los ntawm kev hloov pauv hauv lub sijhawm ntawm cov pa roj thiab lub zog inertia ntawm ntau qhov txav ntawm lub cav thaum lub sijhawm ua haujlwm. Ntawm lawv, qhov tseem ceeb tshaj plaws yog cov hauv qab no: suab nrov los ntawm piston crank txuas pas nrig mechanism, suab nrov los ntawm lub valve faib tshuab, suab nrov ntawm cov iav kis tau tus mob, cov tshuab vibration thiab suab nrov tshwm sim los ntawm lub zog inertia tsis sib npaug. Lub zog mechanical vibration ntawm lub cav diesel tuaj yeem nthuav tawm mus rau ntau qhov chaw sab nraum zoov los ntawm lub hauv paus, thiab tom qab ntawd tsim suab nrov los ntawm cov hluav taws xob hauv av. Hom qauv suab nrov no nthuav tawm deb thiab tsis tshua muaj attenuation, ua rau nws nyuaj rau cais tawm thaum nws tsim.

3. Combustion suab nrov

combustion suab nrov yog cov qauv kev co thiab suab nrov tsim los ntawm diesel thaum lub sij hawm combustion txheej txheem. Lub suab siab ntawm combustion suab nrov nyob rau hauv lub tog raj kheej yog siab heev, tab sis feem ntau qhov chaw nyob rau hauv lub cav qauv muaj siab rigidity, thiab lawv tej yam ntuj tso frequencies yog feem ntau nyob rau hauv nruab nrab mus rau high zaus ntau yam. Vim qhov tsis sib haum xeeb hauv cov lus teb rau qhov zaus ntawm lub suab yoj tawm, lub ncov tus nqi ntawm lub tog raj kheej siab theem nyob rau hauv qhov tsawg zaus tsis tuaj yeem kis tau yooj yim, thaum lub tog raj kheej siab theem nyob rau hauv nruab nrab mus rau siab zaus ntau yog kuj yooj yim rau kis.

4. Cov kiv cua txias thiab lub suab nrov

Lub suab nrov ntawm chav kiv cua yog tsim los ntawm cov suab nrov tam sim no thiab cov suab nrov tig, thiab lub suab nrov yog tshwm sim los ntawm kev cuam tshuam ib ntus tsim los ntawm kev txiav cov cua ntws los ntawm cov kiv cua; Vortex suab nrov yog ib yam ntawm cov suab nrov tsis khov kho uas tshwm sim los ntawm viscosity ntawm cov pa roj thaum cov cua ntws sib cais ntawm ib qho rotating hniav seem. Cov pa tawm suab nrov, suab nrov airflow, kiv cua suab nrov, thiab cov suab nrov ntawm cov tshuab yog txhua yam tawm los ntawm cov pa tawm.
