Explosion-proof contact pressure gauge raws li lub teb chaws tus qauv: GB/T1226-2001 "General Pressure Gauge" National Standard, 2-2000 "Blasting Gas Environment Electrical Equipment No. 9: Explosion-proof "c"" ntsig txog cov cai thiab JB/T9773- 1999 "Electrical Contact Pressure Gauge" cov txheej txheem tshaj lij kev npaj thiab tsim khoom. Hom tawg-pov thawj ntawm qhov tawg-pov thawj tiv thaiv qhov ntsuas siab yog hom tawg-pov thawj, thiab nws cov cim pov thawj tawg yog dⅡCT4.
Nws yog siv los ua ke nrog cov khoom siv hluav taws xob nrog cov khoom tawg-pov thawj los ntawm cov khoom siv sib cuag. Rau qhov siab ntawm qhov ntsuas nruab nrab, nws muaj ntau yam haujlwm xws li kev tswj tsis siv neeg, tswb, thiab cov teeb liab kis tau tus mob.
Lus Cim: Thaum ntsuas corrosive, crystalline thiab condensing media, nws yog ib qho tsim nyog yuav tsum tau siv cov kua qaub-resistant, tiv thaiv corrosion los yog barrier tawg-pov thawj hluav taws xob tiv tauj ntsuas ntsuas ntsuas me me (10Kpa ~ 60Kpa). Rau qee lub sijhawm, thov xaiv cov khoom siv hluav taws xob sib nqus-pab tawg-pov thawj hluav taws xob tiv thaiv lub ntsuas hluav taws xob lossis lub zog tiv thaiv photoelectric teeb liab tawg-pov thawj hluav taws xob tiv thaiv kev ntsuas siab, thiab siv lub tshuab hluav taws xob tiv thaiv hluav taws xob tiv thaiv hluav taws xob rau qhov ntsuas qhov tseeb thiab lub sijhawm zoo siab.
1. Siv
Explosion-proof contact pressure gauges yog siv nyob rau hauv cov xwm txheej uas ib puag ncig muaj kev pheej hmoo ntawm explosive sib tov los ntsuas lub siab (tsis zoo siab) ntawm non-corrosive non-crystalline, non-condensing media xws li tooj liab thiab tooj liab alloys, feem ntau carbon steel. Nws yog siv los ua ke nrog cov khoom siv hluav taws xob nrog cov khoom tawg-pov thawj los ntawm cov khoom siv sib cuag. Rau qhov siab ntawm qhov ntsuas nruab nrab, nws muaj ntau yam haujlwm xws li kev tswj tsis siv neeg, tswb, thiab cov teeb liab kis tau tus mob.
Lus Cim: Thaum ntsuas corrosive, crystalline thiab condensing media, nws yog ib qho tsim nyog yuav tsum tau siv cov kua qaub-resistant, tiv thaiv corrosion los yog barrier tawg-pov thawj hluav taws xob tiv tauj ntsuas ntsuas ntsuas me me (10Kpa ~ 60Kpa). Rau qee lub sijhawm, thov xaiv cov khoom siv hluav taws xob sib nqus-pab tawg-pov thawj hluav taws xob tiv thaiv lub ntsuas hluav taws xob lossis lub zog tiv thaiv photoelectric teeb liab tawg-pov thawj hluav taws xob tiv thaiv kev ntsuas siab, thiab siv lub tshuab hluav taws xob tiv thaiv hluav taws xob tiv thaiv hluav taws xob rau qhov ntsuas qhov tseeb thiab lub sijhawm zoo siab.
3. Cov qauv thiab cov qauv kev ua haujlwm
1. Explosion-proof contact pressure gauge Explosion-proof contact pressure gauge shell adopts explosion-proof structure. Thaum cov khoom tawg hauv lub plhaub raug cuam tshuam los ntawm cov nplaim taws lossis arcs, thaum blasting tshwm sim, nws yuav tsis ua rau cov khoom tawg tawm sab nraud kom tawg, thiab tom qab ntawd mus txog lub hom phiaj ntawm kev tawg-pov thawj.
2. Cov khoom tawg-pov thawj tiv thaiv kev ntsuas siab yog tsim los ntawm reed yeeb nkab siab ntsuas thiab cov khoom siv hluav taws xob sib txuas.
Lub hauv paus ntsiab lus ntawm kev tawg-pov thawj tiv thaiv kev ntsuas siab: thaum ntsuas nruab nrab nkag mus rau hauv cov kav dej reed, qhov hloov ntawm lub raj reed tau nthuav dav, thiab tom qab lub tshuab xa tawm tau nthuav dav, tus pointer yuav qhia qhov ntsuas qhov ntsuas ntawm lub dial, thiab tus pointer yuav tsav lub zog ntawm cov khoom siv hluav taws xob sib txuas. Kev sib cuag, thaum lub siab ncav cuag tus nqi uas tau txiav txim siab, qhov kev sib tiv tauj tau kov cov kev sib cuag ntawm tus pin qhov chaw, thiab lub voj voog txuas nrog.
3. Sab hauv txoj kab uas hla ntawm cov khoom siv roj hmab sealing nplhaib yog 10mm, Lub Nkoj hardness yog 45-55, thiab sab nraud txoj kab uas hla yog 9.8mm, 500VBX hom plaub-core roj hmab xaim (4XI)
