Redhiyo yakarira pakamuka moto muhotera iri pedyo pauriri hwechishanu. Maminitsi mashoma gare gare, uri kushandisa bhegi rako rinosimudza pombi kugadzira zvibatanidza—ndiko kuti, “pfekedza pombi”—pakumhara pauriri hwechina, uye pauriri hwepamusoro pamusoro pako, zvinoita sokunge kuti simisitisi yokumwayira yakashata. Hotel. Iyi ingangove mamiriro ezvinhu anoshungurudza aungave kana kuti usati wambosangana nawo; kuita zvinhu zvidiki zvakanaka kuchabatsira kukunda kushushikana, uye kubudirira kudiki kunoshanduka kuve kubudirira kukuru. Vamwe vanhu vanogona kufunga kuti chimwe chezvinhu zvidiki ndezvekukurumidza, "Usakanganwa kugezesa!"
Kutsvaira riser isati yashandiswa nedhipatimendi remoto haisi basa diki, asi inhanho yakakosha inogona kushandiswa kune zvinangwa zvakawanda uye inokanganisa zvakanyanya mhedzisiro yemabasa ekudzima moto. Flushing inosimbisa kuvimbika kwekusimuka, mvura yayo uye kushanda kwevhavha; anobvisa tsvina mupombi; uye inokupa nguva yekugadzirisa matambudziko pachine nguva.
Mvura inoyerera ichibva pamukwidza inosimbisa kuti pombi ine tsime remvura. Kune akawanda ekupa mvura mikana yekusimudza masisitimu; tinofanira kuziva dzimwe sarudzo dzakajairika. Mapombi anogona kupihwa nemapombi anodzvanywa emoto, matsime emvura ekanzuru ane kana asina kumanikidzwa kwakakwana, kana Fire Department Connection (FDC) chete. Ndinovimba wakaronga chivakwa ichi pachine uye unonzwisisa hurongwa hwaunoda kushandisa. Mune akawanda anodzvanywa pombi yemoto masisitimu, paunovhura vharuvhu yekutsvaira, iyo system yekumanikidza inodonha, uye pombi yemoto inonzwa kudonha kwekumanikidza, wobva watanga nekupa mvura yakamanikidzwa kuhurongwa. Izvi ndizvo zvauri kuda kuti zviitike kune sisitimu inopihwa nepombi yemoto yekuvaka.
Saizvozvo, kana FDC nejini zvakabatana uye zvanyatsoputirwa, mvura inoyerera kunze kana vharafu ichinyungudutswa, uye zvese zvakanaka. Zvisinei, kana iwe ukazarura valve uye pasina mvura inoyerera kunze, zvinogona kureva kuti valve iri pasi peimba yepombi kana stair riser haina kuvhurwa, injini yakabatana nekubatana kusina kunaka, kana chimwe chikonzero. Pamwe pombi yemoto yakaremara kana simiti pachayo yakakuvadzwa, Zvisinei, hapana mvura inoyerera ichibva mupombi ingava mhedzisiro yakajairika yezvigadziriso zvemanyorero akaoma kana emaoko masisitimu anonyorova anovimba neFDC pakugovera mvura uye asina kubatana.
Vhuru yekusimudza inogona kunge isati yashandiswa muchivako kwemakore akawanda, kana kuti inogona kunge yakakuvadzwa nekuda kwechinangwa chekupara mhosva kana kukuvadzwa nevagari vezvivakwa vane ruzivo mumazuva mashoma apfuura. Kubva pakuiswa kwekutanga kana kushandiswa kwekupedzisira kusvika pazuva raunoda kuti rishande, zvinhu zvakawanda zvinogona kuitika. Kuti uve nechokwadi chekubudirira, bvisa chivharo uye isa dhipatimendi remoto gedhi valve (mufananidzo 1) usati wavhura vharafu yekuvaka. Unotakura vharuvhu iyi newe, unoziva kuti inogona kushanda, uye wakagamuchira kudzidziswa kwayo zuva iroro risati rasvika.
Mushure mekuisa vharuvhu yedhipatimendi remoto, vhura vharuvhu yekuvaka kamwe chete kuti uvhare sisitimu, wozoichengeta yakavhurika. Kuvhura valve yekuvaka kungada basa; zvinotarisirwa kunetsa kuvhura. Ita chero chaunofanira kuita kuti uivhure-irove, penya, kana kushandisa chipanera chepombi. Kana yangozaruka uye wagezesa sisitimu, chengeta vharanda rekuvaka rakavhurika uye shandisa dhipatimendi remoto gedhi vharafu kuvhara kuyerera kwemvura. Mushandi anogona kuramba achicheka pombi uye kuwedzera magokora, akaiswa mamita, hose, nezvimwewo, kuitira kuti pombi igadzirire kushandiswa (mufananidzo 2-3). Ivharuvhu yegedhi redhipatimendi remoto inobvumira vanodzima moto vanosimudza masitepisi kuti vasete kudzvanya kwakakodzera apo pombi inenge ichiyerera nepamasitepisi isati yadzima moto; mumamiriro ezvinhu asingazivikanwi, kushandisa gedhi revhavha kuvhara kuyerera kwemvura kunowanzova nyore kupfuura kushandisa chivako chekuvaka. Kana moto wadzima uye kushanda kwapera, vashandi vanogona kubata nekuvhara mavharuvhu ekuvaka kuti vadzorere mabasa avo emidziyo.
Iko kudikanwa kwekutsvaira marara kubva pane inosimudza system iri nyore kunzwisisa. Madhipoziti emvura yakaoma, chiyero, matoyi, marara, uye chero nhamba yezvinhu zvinogona kupinda mustandpipe system. Diva mvura inokwana kuburitsa zvinhu izvi kunze kwesystem uye papuratifomu. Zviri nyore kukwesha zvinhu zvekunze kuburikidza ne 2½-inch valve pane kuburikidza ne11⁄8-inch nozzle tip. Kutsvaira nekuomesa sisitimu hakungobvisi marara chete, asiwo kuburitsa mweya wakaunganidzwa muhurongwa kugadzirira sisitimu yekurwisa moto. Kutora nguva shoma ikozvino kuburitsa kunze zvinhu zvinogona kuvhara mhuno zvinogona kupihwa mubairo nenzira dzisingaverengeki mumabasa ekudzima moto.
Pakupedzisira, vashandi havana kuda kukanganwa kushambidza, nokuti zvakavapa nguva yekukunda dambudziko racho. Vanodzima moto vari mumasitepisi vanofanira kudonhedza mvura yakawanda kubva pamukwidza nekukurumidza, asi vamwe vashandi vari kuwedzera pombi uye kugadzirira mabasa ekudzima moto.
Semuenzaniso, kana chivako chacho chine bhuku rakaoma revhavha uye injini yevashandi vekunze inoshuma kuti yakabatanidzwa kune chivako uye inopa mvura, asi musimudzi wemoto anosimudza anozarura vharafu ye stairwell asi hapana chinobuda. Dambudziko nderei? Sitimu yakuvadzwa here, vharuvhu yekamuri yepombi yakavharwa here, kana kuti injini yakabatana nekubatanidza sipori? Iyo inokurumidza mutungamiriri wechiitiko akadzidza nezvedambudziko, zviri nyore kurigadzirisa pasina kuwedzera zvakanyanya nguva yekupindura (nguva kubva pakutumira kuenda kukudzingirira moto). Mifananidzo 4 ne5 inoratidza vadzimi vemoto vakawanikwa muchivako chinogarwa muOklahoma City, Oklahoma. Nzvimbo yacho yakafanorongwa uye kusimuka kwekubatanidza kwakakurukurwa nenhengo itsva.
Mumwe muenzaniso wekumisa vanodzima moto ndeye manual wet system yakabatana kune yakaderera pasi, ine pasi zhinji pamusoro penzvimbo yemoto. Iyo wet system inozadzwa nemvura asi haina kubatana kune yakamanikidzwa mvura yekupa system. Panosangana nhurikidzwa yechishanu yechivako chine nhurikidzwa gumi neshanu, pane 120 kusvika 150-mamita-refu-yakareba-yakazara mvura inosimudza sisitimu pamusoro pemuchinjiko. Izvi zvinogadzira kudzvanywa kwemusoro kwe60 kusvika 70 pounds per square inch (psi) kubva mumvura iri pamusoro pevharuvhu mupombi. Rangarira kuti tsoka yega yega yekusimuka mune inosimuka ichaisa 0.434 psi yekumanikidza.
Mumuenzaniso uri pamusoro, 120 tsoka × 0.434 = 52 psi, uye 150 tsoka × 0.434 = 65 psi. Kana iwe ukangorega vharuvhu ichiyerera kwesekondi imwe chete, iyo system inoita seine kumanikidza kwakakwana uye huwandu hwemvura. Zvisinei, chaizvoizvo, pombi inongobvisa mvura kubva papombi pamusoro payo, nokuti iyo standpipe yakagadzirirwa kuita kuti dhipatimendi remoto ripe mvura yekurwisana kwemoto chaiwo. Ndicho chikonzero nei zvakakosha kugezesa mvura yakakwana kuti uone kana pombi inongobviswa kana kupihwa kubva patsime remvura.
Mamiriro akafanana mumhando iyi yehurongwa ndeyekuti dzimwe nguva pombi diki inodzorwa inopa mvura muhurongwa. Paunovhura valve uye mvura shoma chete inobuda, iyo booster pump inotanga uye zvishoma nezvishoma edza kuzadza hurongwa. Kana vashandi vasina kuyerera kwakakwana, mushandisi anozofunga zvisiri izvo kuti kune tsime remvura. Vashandi vanokurumidza kudzidza nezvemhinduro dzemibvunzo iyi, ndiko kukurumidza kwavanogona kubata nayo nekuikunda.
Kana iwe ukatora nguva yekugadzirira, iyo riser operation inogona kuve yakarongeka uye isina kunetseka. Dzidzira zvinhu zvidiki izvi, sanganisa kudzidziswa zvisina tsarukano, uye edza kugadzirisa zvinogona kuitika standpipe zvinonetsa. Yeuka, kana tikaita zvinhu zviduku zvakanaka, zvinowedzera kusvika pakubudirira kukuru, izvo zvinogona kuita kuti riser firefighting basa rifambe zvakanaka.
JOSH PEARCY akatanga basa rake rekudzima moto muna 2001 ari lieutenant muOklahoma City (Zvakanaka) Dhipatimendi reMoto uye akagoverwa kunzvimbo yakakosha yekununura. Iye inyika yakanyoreswa paramedic uye firefighting, EMS, diving uye hunyanzvi hwekununura murairidzi. Ndiye mudzidzisi weFDIC International uye mutariri weboka rekutsvaga uye rekununura / nyanzvi yekununura yehelicopter yeOK-TF1 yekutsvaga kwemaguta neboka rekununura.
