Fire kudzvinyirira hurongwa. fireplug
Nokuti moto kudzivirira zvivako siyana kana zvivako, akaisa moto mutsetse. Inside basa akashongedzerwa nomoto-chivhariso unobatanidza kuti moto mukuru. Maererano nezvinodiwa SNiPP-30-76, ane moto chikuru moto hydrants zviri kuiswa mune dzinogarwa mukuru-vosimba zvivakwa.
Fire vharafu akashongedzerwa:
- moto vharafu dhayamita makumi mashanu kana matanhatu millimeters, chokuita unosimudza bazi;
- hosipaipi (hemp ruoko) pakureba 10-20 M;
- bystrosmykayuschimisya polugankami;
- moto mudhiramu nemvura ndege (kamwene) dhayamita 13 mm (uye zvinogonawo kuva dhayamita 16, 19, 22 mm).
Fireplug akaiswa pana 1.35 metres kubva plinth iri rinokosha makabhati akanzi "PC". Aiwanzopiwa wokushanda taps vanoiswa rimwe pamusoro mumwe nechokure mumwe mita pamusoro skirting bhodhi. Sezvo nomwoyo moto-vachirwa midziyo, nzvimbo zvinhu izvi zvinomiririra mumoto makachengeteka urongwa. Akaisa pedo rinokosha chiratidzo: Fire tepi chena iri dzvuku munda.
Kana moto mutsetse vanopfuura gumi nevaviri moto hydrants, ivo thick shure uye chokuita emimbure miviri kana kupfuura zvinoshandisa pakurima. Uwandu zvinhu pakutsvaga nzvimbo kudiridzwa zvivako muimba. The nharaunda chiito pamusoro Crane rinowanikwa kubudikidza nzira: R = L1 + L2,
apo R - nharaunda kwaitwa ane moto the hydrant,
L1 - Sleeves urefu (hosipaipi) moto the hydrant;
L2 - pamwero tsindirana chikamu ndege wakaenzana kureba mukamuri apo moto the hydrant iri yakaiswa, asi kwete isingasviki mitanhatu metres zvivako, nekukwirira, rinosvika 50 m, uye vanenge sere metres muzvivako akareba kupfuura 50 m.

The nharaunda kwaitwa ane moto the hydrant haafaniri kuva asingasviki gumi meters (zvivakwa pazasi 50 m) uye makumi maviri nezvitanhatu meters (zvivakwa pamusoro 50 m). Pasi mumoto hydrants zviri kuiswa nenzira kuti chero nguva mukamuri yaigona unodiridzwa ne jets kubva namano dzinenge mbiri. Kuwanda mawa moto hydrants uye shoma mvura iyerere kunogona kuonekwa Table 1.
Kana ukashandisa vaviri mano pamusoro chete pombi anogona kuiswa coaxial vharafu. Fire vharuvhu akatasva ane dhayamita 50 mm. Imwe mvura jeti kunoda 2,5 litres / chik kana 5 l / s, nhamba jets kuita pamwe chete, haafaniri kupfuudza masere.
