13.Lub tshuab tso pa tawm nyob rau sab ntawm lub chassis, uas tuaj yeem ua tau zoo thiab ceev cov pa tso pa tawm, uas tuaj yeem ua kom muaj cov pa oxygen hauv lub thawv thaum lub sijhawm kuaj thiab ua kom cov txiaj ntsig tau zoo dua.

14.Continuous detection device: Thaum lub sij hawm qhov kev xeem, qhov tam sim no tau dhau los ntawm tag nrho cov cores ntawm lub cable, thiab peb ib-theem transformers muaj peev xwm txaus los tuav lub siab tshaj plaws tso tawm tam sim no ntawm qhov ntsuas voltage. Txuas lub teeb rau txhua tus tub ntxhais hlau ntawm lwm qhov kawg ntawm lub cable, thiab thauj khoom tam sim no ze rau 0.11A ntawm qhov ntsuas hluav taws xob ntawm lub cable. Thaum cov qauv luv luv / qhib thaum lub sijhawm kuaj, tag nrho cov teeb liab tawm.

15.Cov cuab yeej muaj cov cuab yeej tiv thaiv kev nyab xeeb hauv qab no: lub zog muab hluav taws xob ntau dhau, kev tiv thaiv luv luv, tiv thaiv Circuit Court overload tiv thaiv.

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.Test ib puag ncig: sab nraud ambient kub ntawm lub chamber yuav tsum tau khaws cia ntawm 5 ℃ thiab 40 ℃.

Mass Flow Controller

Tus tswj huab hwm coj loj yog siv rau kev ntsuas qhov tseeb thiab kev tswj hwm ntawm cov pa loj. Mass flow meters muaj cov yam ntxwv ntawm qhov raug siab, zoo rov ua tau zoo, cov lus teb ceev ceev, pib muag muag, ruaj khov thiab kev ntseeg siab, kev ua haujlwm siab ntau yam. Nrog cov txheej txheem thoob ntiaj teb txuas, nws yooj yim rau kev khiav lag luam thiab siv, tuaj yeem ntsia tau rau hauv txhua txoj haujlwm, thiab yooj yim rau kev txuas nrog lub computer rau kev tswj tsis siv neeg.

Mass Flow Controller Technical Parameters:

1.Accuracy: ±2% F.S

2.Linearity：±1% F.S

3.Repeat accuracy：±0.2% F.S

4.Response time：1 ~ 4 sec

5.Pressure resistance: 3 Mpa

6.Working environment：5 ~ 45℃

7.Input qauv: 0-+5v

Cov kev ua tau zoo ntawm cov tester, suav nrog kev ntsuas hluav taws kub (B, cable lossis fiber ntau optic cable kab kev ntseeg siab combustion tester), dej tshuaj tua hluav taws ntsuas thiab ntsuas hluav taws xob txhua yam, muaj feem xyuam rau cov ntxhia insulated cables nrog qhov ntsuas voltage tsis tshaj 450 / 750V, nyob rau hauv cov nplaim taws rau lub sijhawm ntev los ua kom lub cev muaj zog.

Ua raws li tus qauv hluav taws xob tiv thaiv kab hluav taws xob BS6387 "Kev Ua Tau Zoo Cov Lus Qhia rau Cables kom Tswj Xyuas Kev Ncaj Ncees Hauv Qhov Teeb Meem Hluav Taws Xob".

1.Heat qhov chaw: ib tug 610 hli ntev nplaim-intensive tubular gas burner uas yuav raug yuam kom muab roj.

2.Temperature ntsuas: 2 hli txoj kab uas hla armored tus pas ntsuas kub yog muab tso rau ze ntawm cov cua inlet, parallel rau lub burner thiab 75 hli saum toj no.

3.Dej tshuaj tsuag: lub taub hau tshuaj tsuag yog mounted rau ntawm qhov chaw kuaj, kuj nyob rau hauv nruab nrab ntawm lub burner. Cov dej siab yog 250KPa txog 350KPa, txau 0.25L / m² mus txog 0.30L / m² ntawm cov dej nyob ze ntawm tus qauv. Tus nqi no yuav tsum tau ntsuas nrog lub tais uas muaj qhov tob txaus kom tso cai rau nws qhov ntev axis mus rau lub axis ntawm lub cable thiab muab tso rau hauv qhov chaw. Lub tais no yog hais txog 100 hli dav thiab 400 hli ntev (lub cuab yeej yog qhia hauv qab).

Hluav Taws thiab Dej Resistance Test Device:

Vibration Device:

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.

Water Spray Test Device Thiab Dej Jet Test Device:

1.Dej tshuaj tsuag: txuas cov yeeb nkab xeem, xyuas kom tsis muaj teeb meem nrog kev sib txuas, nias lub tshuab nqus dej kom pib, manually kho cov dej ntws tswj "Kho 2" (qhov no ntws yog 0-1.4LPM ntau) ntawm qhov loj vaj huam sib luag ntawm lub lag luam txee kom ncav cuag qhov kev xav tau ntawm kev ntsuas.

2.Dej dav hlau: Txuas cov tshuaj tsuag nozzle siv rau kev sim, xyuas kom tsis muaj teeb meem nrog kev sib txuas, nias lub dav hlau dej pib, manually kho cov dej ntws tswj "Kho 1" (qhov no ntws yog 2-18LPM ntau yam) nyob rau ntawm lub vaj huam sib luag loj ntawm lub txee ua haujlwm kom ncav cuag qhov kev xav tau ntawm qhov ntsuas.

3.Qhov kev ua haujlwm ntawm cov dej tso tawm khawm yog ntxiv rau qhov kev zov me nyuam: kaw cov dej nkag valve thiab nias lub pob tso dej tso tawm kom ntws cov dej seem hauv cov kav dej. Yog tias lub tshuab tsis tas yuav ua haujlwm rau lub caij ntuj no, nws raug nquahu kom tshem tawm cov yeeb nkab txuas thiab nias lub tso dej tso tawm kom tso cov dej seem hauv lub flowmeter kom tsis txhob khov ntawm qhov ntsuas.
