I-13.Inkqubo yokukhupha ibekwe kwicala le-chassis, enokuthi ikhuphe ngokufanelekileyo kwaye ngokukhawuleza ikhuphe igesi yokukhupha, enokuqinisekisa umxholo we-oksijini kwibhokisi ngexesha lovavanyo kwaye wenze iziphumo zovavanyo zichaneke ngakumbi.

I-14.Isixhobo sokufumanisa ngokuqhubekayo: Ngethuba lovavanyo, okwangoku idluliselwe kuzo zonke iinqununu zekhebula, kwaye i-transformers ezintathu zesigaba esisodwa zinomthamo owaneleyo wokugcina ubuninzi obuvumelekileyo bokuvuza okwangoku kumbane wokuvavanya. Xhuma isibane kucingo ngalunye oluphambili kwelinye icala lekhebula, kwaye ulayishe i-current kufuphi ne-0.11A kwi-voltage elinganisiweyo yekhebula. Xa isampuli ifutshane / ivuliwe ngexesha lovavanyo, zonke iimpawu ziphuma.

I-15.Isixhobo sinezixhobo ezilandelayo zokukhusela ukhuseleko: ukugqithiswa kwamandla ombane, ukukhuselwa kwesiphaluka esifutshane, ukukhuselwa komthwalo wesiphaluka.

1.The equipment test is carried out in a 3 x 3 x 3(m) combustion chamber (customer-supplied), the chamber has the facility to exclude any gas produced by combustion, and there is sufficient ventilation to maintain the flame during the test.

2.Imeko yovavanyo: iqondo lokushisa langaphandle legumbi kufuneka ligcinwe phakathi kwe-5℃ kunye ne-40℃.

Umlawuli wokuHamba kweMisa

Isilawuli sokuhamba kobunzima sisetyenziselwa ukulinganisa okuchanekileyo kunye nokulawula ukuhamba kobuninzi begesi. Iimitha zokuhamba kobuninzi zineempawu zokuchaneka okuphezulu, ukuphindaphinda okulungileyo, ukuphendula ngokukhawuleza, ukuqala okuthambileyo, ukuzinza kunye nokuthembeka, uluhlu olubanzi loxinzelelo lokusebenza. Ngeekhonkco ezisemgangathweni zamazwe ngamazwe, kulula ukuyisebenzisa kunye nokusetyenziswa, inokufakwa kuyo nayiphi na indawo, kwaye kulula ukudibanisa nekhompyutheni yokulawula ngokuzenzekelayo.

Isilawuli sokuhamba kobunzima iiparamitha zobugcisa:

1.Accuracy: ±2% F.S

2.Linearity：±1% F.S

3.Repeat accuracy：±0.2% F.S

4.Response time：1 ~ 4 sec

5.Ukuxhathisa uxinzelelo: 3 Mpa

6.Working environment：5 ~ 45℃

7.Imodeli yegalelo: 0-+5v

Iimfuno zokusebenza komvavanyi, kubandakanya icandelo lovavanyo lokumelana nomlilo (B, intambo okanye i-fiber optic cable line integrity combustion tester), uvavanyo lokumelana nomlilo wokutshiza kunye novavanyo lokumelana nomlilo kumatshini, ziyasebenza kwiintambo ezifakwe kwiminerali ezifakwe kwi-voltage engagqithiyo kuma-450. / 750V, phantsi kweemeko zomlilo ixesha elide ukugcina ingqibelelo yesiphaluka.

Ithobelana nomgangatho we-cable-resistant cable standard BS6387 "Inkcazo yeeMfuno zokuSebenza kwiiCables ukuze kugcinwe imfezeko yeSekethe kwiSiganeko soMlilo".

I-1.Umthombo wokushisa: i-610 mm i-flame-intensive-intensive gas burner ye-tubular inokunyanzeliswa ukuba ibonelele ngegesi.

2. Umlinganiselo wobushushu: i-2mm ye-armored thermometer ibekwe kufuphi nendawo yokungenisa umoya, ngokuhambelana ne-burner kunye ne-75 mm ngaphezulu.

3.Isitshizi samanzi: intloko yokutshiza ifakwe kwindawo yokuvavanya, kwakhona phakathi kwesitshisi. Uxinzelelo lwamanzi ngu-250KPa ukuya kwi-350KPa, ukutshiza i-0.25L / m² ukuya ku-0.30L/m² yamanzi kufuphi nesampulu. Eli nqanaba lifuna ukulinganiswa ngetreyi enobunzulu obaneleyo ukuvumela i-axis yakhe ende ihambelane ne-axis yentambo kwaye ibekwe embindini. Le tray imalunga ne-100 mm ububanzi kunye ne-400 mm ubude (isixhobo siboniswe ngezantsi).

IsiXhobo sokuVavanya ukuFakiswa koMlilo naManzi:

Isixhobo sokungcangcazela:

The vibration device is a low carbon steel rod (25mm in diameter and 600mm in length). The longitudinal section of the rod is parallel to the wall and 200mm above the top of the wall. A shaft divides it into two parts of 200 mm and 400 mm, and the long part faces the wall. Falling from the inclined position to the middle position of the wall from 60°C separated by 30±2s.

Isixhobo soVavanyo lweSitshizi saManzi kunye nesixhobo soVavanyo lweJet yaManzi:

I-1.I-spray yamanzi: qhagamshela umbhobho wokuvavanya, qiniseka ukuba akukho ngxaki ngokudibanisa, cinezela i-spray yamanzi ukuze uqale, ulungelelanise umgaqo wokuhamba kwamanzi "Lungisa i-2" (oku kuhamba kuluhlu lwe-0-1.4LPM) kwindawo enkulu. Iphaneli yekhabhinethi yokusebenza ukufikelela kwimfuno yovavanyo.

I-2.Ijethi yamanzi: Qhagamshela umbhobho wokutshiza osetyenziselwa uvavanyo, qiniseka ukuba akukho ngxaki ngoqhagamshelo, cinezela ijethi yamanzi ukuze uqalise, ulungise ngesandla ummiselo wokuhamba kwamanzi "Lungisa i-1" (oku kuhamba kuluhlu lwe-2-18LPM) kwiphaneli enkulu yekhabhathi yokusebenza ukufikelela kwimfuno yovavanyo.

3.Umsebenzi weqhosha lokutshintsha ukukhutshwa kwamanzi wongezwa kwiprogram: vala ivalve yokungena kwamanzi kwaye ucinezele iqhosha lokukhupha amanzi ukuze ukhuphe amanzi aseleyo kumbhobho. Ukuba umatshini awudingi ukusebenza ebusika, kuyacetyiswa ukuba ususe uxhulumaniso lombhobho kwaye ucinezele ukukhutshwa kwamanzi ukukhulula amanzi asele ngaphakathi kwe-flowmeter ukukhusela ukukhenkceza kwesixhobo.
