Cov phom rab phom phoov, sab nraud qog cov tub rog siv riam phom, tau txais koob meej ntau. Lawv raug muag hauv cov khw muag khoom txhua yam dawb, thiab tsis muaj cov ntaub ntawv xav tau los yuav lawv, yog li ntawd, leej twg tuaj yeem yuav xws li cov "thoob" uas tua cov npas hlau ntawm cov nqi ntawm cov huab cua compressed. Qhov no ua rau cov lus nug: nws puas tuaj yeem nqa rab phom pneumatic nrog koj, thiab cov kev txwv dab tsi raug pub los ntawm txoj cai.
Ua ntej tshaj plaws, peb nco ntsoov tias pneumatic riam phom sib txawv, qee cov khoom tuaj yeem nqa nrog txhua tus neeg, lwm tus yuav tsum muaj ntawv tso cai. Txhua yam nws yog nyob ntawm lub muzzle zog - qhov ntsuas uas txiav txim siab lub zog ntawm kev txhaj tshuaj. Nws yog qhov sib npaug ntawm ib nrab ntawm cov khoom ntawm qhov loj ntawm lub mos txwv thiab lub xwmfab ntawm qhov ceev ntawm nws tso tawm thiab ntsuas hauv joules. Kev cai lij choj faib cov pneumatics rau hauv ntau hom nyob ntawm lub muzzle zog - txog 3 J, txog 7,5 J, txog 25 J thiab tshaj 25 J.
Thawj qeb - txog 3 J - suav nrog feem ntau ntawm cov tshuab cua rab phom muaj muag. Raws li txoj cai, tsuas yog cov kev mob ntsws thiaj li tuaj yeem muag rau txhua tus. Qee zaum, cov khoom muaj zog ntau tau muag hauv cov khw muag khoom tsis muaj kev txwv, tab sis lawv yuav tsum tsis nyob ntawd. Yog tias lub suab lub zog tsis pub dhau 3 joules (koj tuaj yeem nrhiav cov ntaub ntawv no hauv daim ntawv pov thawj), xws li rab phom pneumatic tuaj yeem nqa nrog leej twg, txawm tias yog menyuam yaus. Txij li qhov pom ntawm txoj cai lij choj, qhov no tsuas yog ib qho khoom ua si xwb.
Muaj tseeb, muaj ib qho tseem ceeb nuance ntawm no: co koj rab yaj phom cua rau txhua qhov chaw, koj tsis tas yuav qhia nws rau txhua tus neeg qhib siab. Cov neeg tuaj yeem lees txim siab nws nrog rab phom, ceeb toom rau qhov twg tsim nyog, thiab tom qab ntawd koj yuav ntsib kev sib txuas lus tsis zoo nrog cov tub ceev xwm. Nws tseem tsim nyog nco ntsoov tias yog tias koj raug mob rau ib tus neeg nrog rab yaj phom raug rho tawm los ntawm rab yaj phom, nws tseem yuav raug mob uas koj yuav tau tuav lub luag haujlwm. Feem ntau, kev txhaj tshuaj los ntawm cov khoom lag luam no tsis ua rau muaj kev noj qab haus huv (tsuas yog mob me ntsis xwb), tab sis yog tias, piv txwv li, lub pob nkag mus rau hauv lub qhov muag, qhov tshwm sim tuaj yeem loj heev.
Yog li, yog tias koj muaj lub suab qis qis me me cua tshuab rab phom, koj tuaj yeem nqa nrog koj, tab sis koj tsis tas yuav qhia nws rau txhua tus thiab nws raug nquahu kom tsis txhob siv nws. Ib lo lus nug kiag li tshwm sim tam sim ntawd: vim li cas thiaj hnav nws txhua? Qhov tsuas yog ntau dua los yog tsawg dua kev siv pneumatics ntawm txoj kev yog rau kev tiv thaiv tus kheej. Thiab txawm tias tom qab ntawd nws yuav tsis muaj peev xwm los tawm tsam tus neeg tua nrog cov mos txwv, koj tsuas tuaj yeem hem tus neeg uas tsis tuaj yeem paub qhov txawv txav ntawm ntau hom kev muaj riam phom.
Cov piv txwv uas zwm rau pawg thib ob (los ntawm 3 txog 7.5 J) twb yog cov riam phom tau txwv kom yog kev ntaus pob ncaws pob lossis tua tsiaj, nyob ntawm tus qauv. Lawv kuj tau muag hauv ntau lub khw muag khoom, tab sis twb muaj nyob hauv cov kws tshwj xeeb. Thiab tsis yog txhua tus tuaj yeem tuaj yeem yuav ib rab yaj phom lossis phom ntev rau cov qeb no. Txoj cai lij choj tso cai tsuas yog muaj cov laus (muaj hnub nyoog tshaj 18 xyoo) los yuav cov pneumatics. Hauv qhov no, feem ntau rau kev yuav khoom yos hav zoov lossis phom phom, kev tsocai los ntawm kev lis haujlwm hauv cov haujlwm sab hauv yuav tsum tau ua. Txawm li cas los xij, tsab cai lij choj ua rau muaj kev zam rau cov neeg mob ntsws; cov ntaub ntawv no tsis tas yuav tsum ua rau nws.
Raws li rau nqa rab phom nrog lub suab lub zog ntawm 7.5 J nrog koj, nws ua raws los ntawm kev txwv txiav muag rau cov menyuam yaus tias nws tsis raug tso cai nqa lawv rau cov neeg hnub nyoog qis dua 18 xyoo. Rau cov neeg laus, tib cov cai yog muaj feem cuam tshuam thaum hnav pneumatic "cov khoom ua si" - tsis txhob ua kom lwm tus raug mob, tsis txhob hem, tsis ua kom ntshai lwm tus, tsis txhob ua pneumatics zoo li rab phom. Ib qho ntxiv, tseem muaj qhov kev txwv uas yog rab phom tua phom thiab ntaus pob ncaws pob tsis tuaj yeem nqa khoom. Tsis tas li, lawv tsuas tuaj yeem siv rau hauv cov chaw tshwj xeeb (cov chaw tua, tua kab, hav zoov uas tau tso cai yos hav zoov).
Yog tias lub suab lub zog ntawm rab yaj phom lossis cov phom ntev tshaj 7.5 joules, kev kis tau, khaws thiab nqa ntawm cov riam phom yog tswj hwm los ntawm tib cov cai xws li rau rab phom. Yog li, lo lus teb rau lo lus nug ntawm seb koj tuaj yeem nqa tus mob ntsws nrog koj nyob ntawm seb koj puas muaj kev tso cai tsim nyog.
