Namhlanje siza kwabelana ngendlela yokugweba ukuba inzwa isebenza ngokuqhelekileyo.
Okokuqala, kufuneka sazi phantsi kweziphi iimeko ekufuneka sigwebe ukusebenza kweisivamvo. Kukho amanqaku amabini ngolu hlobo lulandelayo:
1. Ubunzima obubonakaliswe ngumqondiso wokulinganisa awuhambelani nobunzima bokwenene, kwaye kukho umehluko omkhulu.
Xa sisebenzisa iintsimbi eziqhelekileyo ukuvavanya ukuchaneka kweisikali, ukuba sifumanisa ukuba ubunzima obubonakaliswe ngumqondiso buhluke kakhulu kubunzima bovavanyo lovavanyo, kwaye inqaku le-zero kunye noluhlu lwesikali alukwazi ukutshintshwa ngokulinganisa, ngoko kufuneka siqwalasele ukuba inzwa ayiphulwanga. Kumsebenzi wethu wangempela, siye sadibana nesimo esinjalo: iphakheji yokulinganisa isikali, ubunzima bepakethi yepakethe yokutya yi-20KG (ubunzima bephakheji bunokusetwa njengoko kufuneka), kodwa xa ubunzima bephakheji bujongwa nge-electronic scale , Nokuba ngaphezulu okanye ngaphantsi, okwahluke kakhulu kumthamo ekujoliswe kuwo we-20KG.
2. Ikhowudi ye-alarm "OL" ibonakala kwisalathisi.
Le khowudi ithetha ukutyeba. Ukuba isalathisi sihlala sichaza le khowudi, khangela ukuba inzwa isebenza kakuhle
Indlela yokugweba ukuba inzwa isebenza ngokuqhelekileyo
Ukuchasa ukulinganisa (Isalathisi sokuqhawula)
(1) Kuya kuba lula kakhulu ukuba kukho i-sensor manual. Okokuqala sebenzisa i-multimeter ukulinganisa igalelo kunye nokuchasana kwemveliso yenzwa, uze uyithelekise kunye nencwadana. Ukuba kukho umahluko omkhulu, kuya kwaphulwa.
(2) Ukuba akukho ncwadana yemigaqo, ke ukulinganisa ukuchasana kwegalelo, okuyiyo ukuchasana phakathi kwe-EXC + kunye ne-EXC-; uxhathiso lwemveliso, luxhathiso phakathi kweSIG + kunye neSIG-; ukuxhathisa ibhulorho, eyi-EXC + ukuya kwi-SIG +, i-EXC + ukuya kwi-SIG-, Ukumelana phakathi kwe-EXC- ukuya kwi-SIG +, i-EXC- ukuya kwi-SIG-. Ukuchasana kwegalelo, ukuchasana kwemveliso, kunye nokuchasana kwebhulorho kufuneka kwanelise ubudlelwane obulandelayo:
"1", ukuxhathisa igalelo＞ukuchasa imveliso＞ukuchasana kwebhulorho
"2", ukuchasana kwebhulorho kuyalingana okanye kuyalingana.
Ukulinganisa amandla ombane (isalathisi sinamandla)
Okokuqala, sebenzisa i-multimeter ukulinganisa i-voltage phakathi kwe-EXC + kunye ne-EXC-i-terminals yesalathisi. Lo ngumbane wokuvuselela wenzwa. Kukho i-DC5V kunye ne-DC10V. Apha sithatha iDC5V njengomzekelo.
Uvakalelo oluphumayo lwezinzwa esizichukumisile ngokuqhelekileyo yi-2 mv/V, oko kukuthi, umqondiso wokuphuma kwenzwa uhambelana nobudlelwane bomgca we-2 mv kuyo yonke i-voltage ye-excitation ye-1V.
Xa kungekho mthwalo, sebenzisa i-multimeter ukulinganisa inani le-mv phakathi kwe-SIG+ kunye ne-SIG- iilayini. Ukuba imalunga ne-1-2mv, ithetha ukuba ichanekile; ukuba inani le-mv likhulu ngokukodwa, oko kuthetha ukuba inzwa yonakele.
Xa ulayisha, sebenzisa ifayile ye-multimeter mv ukulinganisa inani le-mv phakathi kwe-SIG+ kunye nee-SIG-ingcingo. Iya kunyuka ngokulingana nomthwalo olayishiweyo, kwaye ubuninzi buyi-5V (i-voltage excitation) * 2 mv / V (sensitivity) = malunga ne-10mv, ukuba akunjalo , Kuthetha ukuba inzwa yonakele.
1. Awunakugqitha kuluhlu
Uluhlu oluthe gqolo luya kubangela umonakalo ongenakuguqulwa kumzimba we-elastic kunye ne-strain gauge ngaphakathi kwenzwa.
2. I-welding yombane
(1) Nqamula intambo yomqondiso kwisilawuli sokubonisa ubunzima;
(2) Ucingo oluphantsi lwe-welding yombane kufuneka lubekwe kufuphi nenxalenye edibeneyo, kwaye inzwa kufuneka ingabi yinxalenye yesekethe ye-welding yombane.
3. I-Insulation yekhebula lenzwa
I-insulation ye-sensor cable ibhekisela ekuchaseni phakathi kwe-EXC +, i-EXC-, i-SEN +, i-SEN-, i-SIG +, i-SIG- kunye ne-SHIELD yocingo olukhuselayo. Xa ulinganisa, sebenzisa ifayile yokumelana ne-multimeter. Isixhobo sikhethwe kwi-20M, kwaye ixabiso elilinganisiweyo kufuneka libe lingenasiphelo. Ukuba akunjalo, inzwa yonakele.
