Mitirka heerka Ultrasonic

Mitirka heerka ultrasonic-ka waa qalab cabbira oo aan taabanayn oo cabbira heerka dareeraha ama heerka walxaha dareeraha ama walxaha adag iyadoo la adeegsanayo mabda'a milicsiga ultrasonic. Waxay leedahay astaamaha soo socda ee la arki karo:

1. Cabbiraadda aan taabashada lahayn oo leh la qabsi xooggan

Dareemaha si toos ah uma taabtaan qalabka la cabiray, isagoo ka fogaanaya arrimaha sida daxalka, dhegdhegga, iyo xirashada uu keeno qalabka. Waxay si gaar ah ugu habboon tahay xaaladaha shaqada ee adag ee ku lug leh heerkulka sare, cadaadiska sare, walxaha daxalka leh (sida xalalka aashitada), walxaha fiiqan (sida slurry), ama walxaha ka kooban walxaha adag. Waa mid saaxiibtinimo leh xaaladaha leh shuruudaha nadaafadda sare (sida warshadaha cuntada iyo daawooyinka) mana wasakheyn doonto agabka.

2. Cabbiraad ballaaran iyo dabacsanaan sare

Cabbirka cabbirku wuxuu noqon karaa tobanaan sentimitir ilaa tobanaan mitir (iyadoo ku xiran qaabka iyo xaaladaha shaqada), taas oo dabooli karta baahiyaha cabbirka heerka dareeraha/heerka agabka ee xaaladaha warshadaha badankood (sida haamaha kaydinta, kildhiyada falcelinta, barkadaha, silos, iwm.). Habka rakibiddu waa mid dabacsan. Waxaa lagu rakibi karaa dusha sare ama dhinaca weelka iyada oo loo marayo biriish iyada oo aan loo gelin meel qoto dheer oo dhexdhexaad ah, taasoo ka dhigaysa dhismaha mid ku habboon.

3. Xawaaraha jawaabta degdega ah iyo waxqabadka waqtiga-dhabta ah ee wanaagsan

Calaamadaha Ultrasonic-ka waxay ku faafaan xawaare degdeg ah (qiyaastii 340m/s hawada) iyadoo leh wareeg cabbir gaaban (badanaa milise ilbiriqsiyo), kaas oo ka tarjumaya isbeddellada firfircoon ee heerka agabka waqtiga dhabta ah. Waxay ku habboon tahay la socodka isbeddellada degdegga ah ee heerka dareeraha/heerka agabka (sida mashiinnada buuxinta, silosyada firfircoon, iwm.).

4. Hawlgal fudud iyo kharash dayactir oo hooseeya

Looma baahna qaab-dhismeedyo farsamo oo adag, habka cabbiraaddana waa mid fudud (qaar ka mid ah moodooyinka ayaa taageera hal-fure). Dayactirka dambe wuxuu u baahan yahay oo keliya nadiifin joogto ah oo lagu sameeyo baaritaanka dareemayaasha si looga fogaado boodhka iyo uumiga biyaha ee saameeya gudbinta calaamadaha, taasoo keenta kharashyo dayactir oo hooseeya. Moodooyinka badankood waxay ku qalabaysan yihiin bandhigyo dijitaal ah ama is-dhexgal isgaarsiineed (sida 4-20mA, RS485), kuwaas oo si toos ah u akhrin kara xogta ama ku xidhi kara nidaamka xakamaynta si loo fududeeyo la socodka fog.

5. Saamaynta sifooyinka jireed ee aaladda

Natiijooyinka cabbiraadda saameyn kuma yeelanayaan sifooyinka jireed ee dhexdhexaadka sida cufnaanta, viscosity, conductivity, iyo heerkulka (gudaha xaddi gaar ah, magdhow heerkulka ayaa loo baahan yahay). Ilaa inta dusha sare ee dhexdhexaadku si wax ku ool ah u muujin karo hirarka ultrasonic, cabbir deggan ayaa la gaari karaa.

6. Xaddidaadaha iyo taxaddarrada

Waxaa saameeya arrimaha deegaanka:

Hirarka Ultrasonic-ka ayaa ku faafa hawada. Haddii ay jiraan hirar hawo oo xooggan, boodh, uumi, xumbo, ama caqabado ku jira weelka (sida walaaqayaasha), waxay sababi kartaa milicsiga calaamadda oo aan shaqaynayn, taasoo saamaynaysa saxnaanta cabbirka ama xitaa horseedi karta guuldarro.

Shuruudaha sare ee interface-ka:

Dusha sare ee qalabka la cabbiray waa inay ahaataa mid siman (sida dareere aan joogto ahayn). Haddii ay tahay dusha dareeraha ah oo si xoog leh isu beddelaya ama dusha dabacsan ee walxaha adag (sida silo budo ah), khaladaad ayaa dhici kara sababtoo ah calaamadaha muuqda ee daciifka ah.

Xaddidaadda heerkulka:

Deegaannada heerkulka sare leh (sida ka badan 80°C) waxay sababi karaan isbeddelo ku yimaada cufnaanta hawada, taasoo saameyn ku yeelan karta xawaaraha faafinta hirarka dhawaaqa. Waa lagama maarmaan in la doorto moodooyinka leh shaqooyinka magdhowga heerkulka sare leh.

Faa'iidooyinka ugu muhiimsan ee mitirada heerka ultrasonic-ka waa kuwa aan la taaban karin, iska caabbinta daxalka, rakibidda iyo dayactirka fudud, iyo codsiyo badan. Waa aalado si caadi ah loogu isticmaalo cabbirka heerka dareeraha/heerka agabka wax soo saarka warshadaha. Si kastaba ha ahaatee, marka la dooranayo, waa in fiiro gaar ah la siiyaa sidii looga fogaan lahaa xasaasiyadda ay u qabaan deegaanka (sida boodhka, uumiga) iyo xaaladda dusha sare ee warbaahinta. Haddii loo baahdo, aaladaha caawiya (sida hagaha hirarka) ama moodooyinka gaarka ah (sida moodooyinka aan qarxin, heerkulka sare) waa in loo isticmaalaa si loola qabsado xaaladaha shaqada ee adag.
